Figure 2: Aruba 6410 ten-slot switch weight warning

WARNING:

- To reduce the risk of personal injury or damage to equipment: ,

- Heed all warnings and cautions throughout the installation instructions.

If you plan to re-ship the switch in its original packaging, remove any transceivers installed in line modules before preparing the switch for shipment. See also Shipping a rack-mounted Aruba 6400 switch chassis.

- Observe local occupational health and safety requirements and guidelines for manual material handling.

The switch is heavy. Avoid personal injury due to the combined weight of the chassis and installed accessories. If your installation process includes manually lifting or carrying the switch instead of using a mechanical lift, uninstall the removable accessories from the switch before moving it. This guide includes information about removing and installing accessories, as well as the weight of the switch and individual accessories.

- Mount devices installed in a rack or cabinet as low as possible. Install the heaviest devices at the bottom and progressively lighter devices above.

- To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is adequately secured.

- Ensure that the rack or cabinet unit in which you plan to mount the 6400 switch is rated to support the full equipment load you plan to install in the unit.

- Before you power up the switch, ground it reliably. See Grounding the chassis.

- Never have more than one power supply or module slot uncovered at a time while the switch is powered on. Install a blank slot cover on any empty management module, line module, power supply, or AC inlet slot opening in the chassis. This ensures the flow of cooling air through the chassis. It also helps to contain radio frequency emissions that may interfere with the operation of other devices.

- Replace only one fan tray at a time. Removing more than one fan tray at a time compromises system cooling, risks damage to the hardware, and can cause the switch to shut down abruptly. When replacing (hot-swapping) a fan tray, complete the process within two minutes. Allowing the switch to operate longer with only one working fan tray (6405) or three working fan trays (6410) installed reduces the flow of cooling air through the switch chassis and will result in the switch shutting down. For more information on fan trays, see Installing a fan tray in an empty fan tray slot.

- To avoid electrical and mechanical hazards, never allow any part of your body, jewelry, tool, or other foreign object to enter any module or power supply slot.

- The switch may use more than one power supply cable. To fully power down the switch, you must disconnect all power supply cables from the switch.

CAUTION:

- Protect the switch and its components from damage caused by ESD (Electrostatic discharge):

• See the ESD information under Preventing electrostatic discharge damage.

•Always wear an ESD wriststrap when handling the switch or its components. Ensure the strap is reliably grounded when installing or removing switch components.

- Hold management modules and line modules by their edges. Do not touch any electronic components or printed circuitry.

- Store uninstalled modules in antistatic bags.

- Do not ship the Aruba 6400 Series switch mounted in a rack without first checking for rack requirements and restrictions. Otherwise, damage to the switch or components may occur. Damage resulting from using unsupported methods or equipment to ship a rack-mounted chassis may void the switch warranty. For more information, see Shipping a rack-mounted Aruba 6400 switch chassis

- Ensure the source circuits for your 6400 Series switch are properly grounded. Connect the switch to the power sources by using the power cords supplied with the switch or power supply units.

- Only Aruba-approved power cords may be used with Aruba devices. See the power cord documentation provided in the latest version of the Aruba 6400 Switch Series Installation and Getting Started Guide. Lost or damaged power cords must be replaced only with Aruba-approved power cords.

- If your installation requires different power cords than the ones supplied with the switch or power supplies, be sure that the cords are adequately sized for the current requirements. In addition, be sure to use power cords displaying the mark of the safety agency that defines the regulations for power cords in your country/region. The mark is your assurance that the power cord can be used safely with the switch and power supply. For more on power cords, see Power cords, power inlet accessories, and power supplies.

- When installing the switch, select AC outlets near the switch for easy access in case the switch must be powered off.

- Do not install the switch in an environment where the operating ambient temperature exceeds its specification. (For environmental specifications, see Specifications.)

- Ensure that the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add the ampere ratings of all devices installed on the same circuit as the 6400 Series switch. Then compare the total with the rating limit for the circuit. The maximum ampere ratings are printed on the devices near their AC power connectors.

- Ensure that the air flow through the chassis is not restricted. Leave a front and rear clearance of at least 30 cm (11.8 inches) for air flow. Air flow direction is front-to-rear. (Fully perforated rack doors are acceptable within the 30 cm spacing.)

• Install a blank slot cover on any empty management module, line module, power supply, or AC inlet slot opening in the chassis. This ensures the flow of cooling air through the chassis. It also helps to contain radio frequency emissions that may interfere with the operation of other devices.

- If a power supply must be removed, and then reinstalled, wait at least 5 seconds before reinstallation. Otherwise, damage to the switch or its components may occur. The power supply needs this time to dissipate any retained power.

- For proper cooling, the 6405 switch requires two fan trays installed and the 6410 switch requires four fan trays installed. For more information on fan trays, see Fan trays.

- For rack-free mounting requirements and warnings, see Mounting the switch.

- Protect the equipment from AC power fluctuations and temporary interruptions with a regulating facility Uninterruptible Power Supply (UPS) device. This device protects the hardware from damage caused by power surges and voltage spikes, which keeps the switch in operation during a power failure.

Space

For easy installation and maintenance, make sure the rack has enough space to accommodate the switch and normal switch maintenance, such as installing or removing management modules, line modules, and fan trays. For dimensions, see Product dimensions.

Safety recommendations

To avoid possible bodily injury and equipment damage, carefully read the following publications before installing your Aruba 6400 Switch:

• Safety, Compliance, and Warranty Information (shipped with the switch)
- START HERE: Installation, Safety, and Regulatory Information for the Aruba 6400 Switches and Accessories (shipped with the switch)
- START HERE: Installation, Safety, and Regulatory Information for the Aruba 6400 Power Supply Units (shipped with the switch and with PSUs)
• All safety recommendations in this chapter
• The chapter titled Installation precautions and guidelines.

NOTE: The recommendations in the listed publications do not cover every possible hazardous condition.

Electricity safety

• Clear the work area of possible electricity hazards, such as ungrounded power extension cables, missing safety grounds, and wet surfaces or wet floors.
• Locate the emergency power-off switch in the room before installation so you can quickly shut power off if an electrical accident occurs.
• Remove all external cables, including power cords, before moving the chassis.
• Do not work alone when the switch has power.

Handling safety

CAUTION: Do not use the handle of a fan tray or a power supply unit, bezel, module locking or extraction levers, or the chassis air vents to lift or move the switch. Any attempt to move the switch with these parts may cause equipment damage and bodily injury.

When you move the switch, follow these guidelines:

• Remove all power supplies, line and management modules, fan trays, and all external cables, including the power cords, before moving the chassis.
• Use a minimum of four people to manually move a chassis weighing more than 100 lbs, and a minimum of two people to manually move a chassis weighing less than 100 lbs. To determine chassis weight, see Aruba 6400 product weights.

WARNING: Aruba recommends using a mechanical lift to move the chassis.

- Lift and lower the chassis slowly. Never move it suddenly.

For information and recommended practices for moving the chassis, see Unpacking, lifting, and moving the chassis.

Preventing electrostatic discharge damage

Be aware of the precautions you must follow when setting up the switch or handling components. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the switch or component.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
  • Always use a properly grounded ESD wrist strap when touching static-sensitive components or assemblies.

Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
• Use an ESD wrist strap connected to an ESD connection point on the switch (see the following image). Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance. To provide proper ground, wear the strap snug against the skin.

1 Remove the bezel and clip the alligator clamp onto the tab used to mount the bezel.

2 Clip the alligator clamp onto the grounding lug.

If you do not have any of the suggested equipment for proper grounding, have an Aruba authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an Aruba authorized reseller.

Laser safety

WARNING: Do not stare into any fiber port or view directly with non-attenuating optical instruments when the switch has power. The laser light emitted from the fiber port may injure your eyes.

The Aruba 6400 switches are Class 1 laser products.

Examining the installation site

The switch must be used indoors. To help ensure correct operation and a long service life for your switch, the installation site must meet the requirements in this section.

Temperature

CAUTION: If condensation appears on the chassis when you move it to a high-temperature environment, dry the chassis before powering it on to avoid short circuits.

To ensure correct switch operation, make sure the room temperature meets the following requirements.

NOTE: Above 1524m (5000ft), reduce maximum operating temperature by 1^ C ( 1.8^ F) per 305m (1000ft) altitude gain.

Table 1: Temperature requirements

Temperature Range
Operating temperature 0°C	to 45°C (32°F to 113°F)
Storage temperature -40°C	to +70°C (-40°F to +158°F)

For more environmental information, see Environmental, safety, and electrical information.

Humidity

Maintain the humidity in your equipment room in the acceptable range, as described below.

• Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.
• Lasting low relative humidity can cause ESD and circuit failure.

Table 2: Humidity requirements

Humidity Range
Operating humidity 15% to 95%	at 45C (104F), noncondensing
Storage humidity 15% to 95%	at 65C (149F), noncondensing

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points. In the worst case, electrostatic adsorption can cause communication failure.

Table 3: Dust concentration limit in the equipment room

Substance Concentration limit (particles/m3)

Dust particles ≤ 3 x 104 (No visible dust on desk in three days)

NOTE: Dust particle diameter ≥ 5 μm

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown below.

Table 4: Harmful gas limits in the equipment room

Gas Max. (mg/m3)
SO_2	0.2
H_2S 0.006
NH_3	0.05
CI2 0.01

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:

• A conduction pattern of capacitance coupling.
- Inductance coupling.
• Electromagnetic wave radiation.
- Common impedance (including the grounding system) coupling.

To prevent EMI, use the following guidelines:

• If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.

• Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.

• Use electromagnetic shielding (for example, shielded interface cables) when necessary.

• To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables indoors only.

Grounding

CAUTION: Reliably ground the switch to protect it from hazards such as lightning shocks, interferences, and ESD discharges. The switch is grounded through the safety wire in the power cords. Aruba recommends an independent grounding connection for the chassis if there is any doubt about the reliability of the grounding through the power mains. The grounding lug is located on the rear of the switch, at the bottom edge. This figure shows the grounding lug on the Aruba 6405 switch. On the Aruba 6410 is located in a similar position.

Make sure the resistance between the chassis and the ground is less than 1 ohm.

Power

Perform the following tasks to meet the power requirements:

Procedure

1. Calculate the system power consumption. The system power consumption varies by module type and density. (See System power consumption.)
2. Identify the number of power supplies. Include sufficient power to meet power consumption and sufficient redundancy to ensure system uptime in the event of a PSU failure.
3. Verify that the power system at the installation site meets the requirements of the power supplies including the input method and rated input voltage. (For power supply unit (PSU) information, see System power consumption.)

Cooling

Plan the installation site for adequate ventilation:

- Leave a minimum of 30 cm (11.81 in) of clearance at the front and rear of the switch. (Perforated rack doors are acceptable within the 30cm spacing.)

NOTE: Air flow into and out of the switch is indicated by the arrows in the image below.

• Ensure that the rack for the switch is well ventilated, with minimal airflow obstruction at the front and rear.
• The installation site HVAC system must be capable of removing all heat generated by the switch.
• Verify that the airflow design of the chassis is compatible with the airflow design of the installation site.

NOTE: If the switch configuration has no information about any module in a slot (i.e. in a default configuration, a line module installed in that slot boots up when power is applied. But if the slot is configured for a different type of line module than installed in the slot, then the installed line module does not boot up when power is applied. See Using controlled shut down to add or replace line modules.

Installing or removing transceivers

WARNING: The SFP and QSFP form-factor optical transceivers are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port.

CAUTION:

- Use only supported, genuine HPE or Aruba transceivers with your switch. Consult Datasheets/Quickspecs for a list of supported transceivers and DACs. Use of non-supported transceivers may result in product malfunction. If you require additional transceivers, contact your authorized Aruba Sales representative.

- When handling line modules and transceivers, always wear an ESD wrist strap. Make sure it has snug skin contact and is reliably grounded.

- Do not remove the dust plug from a transceiver if you are not going to connect an optical fiber to it.

• Before installing a transceiver, first remove any connected optical fiber cable.

- To prevent particles from entering unused transceiver ports, keep dust plugs in any ports where a transceiver is not installed.

For information on Aruba optical transceivers and cable assemblies supported on your Aruba 6400 Switch, see the latest version of the ArubaOS-Switch and ArubaOS-CX Transceiver Guide at https://asp.arubanetworks.com/downloads.

You can install or remove SFP and QSFP form-factor transceivers without having to power off the switch.

Installing a transceiver

1. Wear an ESD wrist strap with snug skin contact and reliable grounding. (See Attaching an ESD wrist strap.)
2. Unpack the module. Hold it carefully by its sides. Avoid touching the plated contacts.
3. Slide the transceiver into a slot until it clicks into place.

Removing a transceiver

1. Wear an ESD wrist strap with snug skin contact and reliable grounding. (See Attaching an ESD wrist strap.)
2. Disconnect the network cable from the transceiver before removing it from the module. Depending on when you purchased your transceiver, it may have either of three different release mechanisms: a plastic tab on the bottom, a wire bail, or a plastic collar.
3. To remove the transceivers that have the plastic tab or plastic collar, push in the plastic tab or collar toward the switch until you see the transceiver release from the switch (you can see it move outward slightly), and then pull it from the slot.

4. To remove the transceivers that have the wire bail, lower the bail until it is approximately horizontal, then using the bail, pull the transceiver from the slot.

5. Place the transceiver in an ESD-protected container.

6. If you are leaving the transceiver slot empty, install a dust cover.

Fan trays are installed in the slots on the rear of the chassis.

CAUTION: For proper cooling and ventilation, a powered-up 6400 Series chassis must have all fan trays installed and all fans in each fan tray running. Do not remove a fan tray from a powered up switch without having a replacement fan tray available. When replacing a fan tray in an operating switch, install the replacement fan tray within two minutes of removing the original fan tray.

CAUTION: Replace only one fan tray at a time. Removing more than one fan tray at a time compromises system cooling, risks damage to the hardware, and can cause the switch to shut down abruptly.

CAUTION: Handle your Aruba 6400 switch fan trays with care. Rough or careless handling can damage these components and result in unplanned down time.

IMPORTANT: The Aruba 6405 Switch operates with two fan trays, and the Aruba 6410 switch operates with four fan trays. For proper air flow, ensure that all fan tray slots are occupied with fully functioning fan trays.

Procedure

1. Select an empty fan tray slot.

2. Insert a fan tray in the fan tray slot. The fan tray latch will sound an audible "click" when properly seated.

3. Tighten the two screws securing the fan tray in the slot.

1. To install another fan tray in another empty slot, repeat steps 1 through 3.

Installing the cable manager

The cable manager attaches through the rack mounting brackets to the rack for 2-post rack mounting. The cable manager attaches through the rack mounting brackets and the four-post mounting spacer for 4-post rack mounting.

Prerequisites

The switch is mounted in a four-post rack or with the rack mounting brackets in the front mounting position in a two post rack mount. (See the illustrations under Two-post rack mounting.)

Procedure

1. Attach five cable retainers to each cable manager bulkhead, as shown.

1. Attach three angle brackets to each cable manager bulkhead. Use the screws provided. (The Aruba 6405 Switch is shipped with two cable manager bulkheads. The Aruba 6410 Switch ships with four cable manager bulkheads.)

1. Install the cable restraints on the cable manager bulkheads, as shown in step 1.

2. Position the cable manager bulkheads over the rack mounting brackets so that the holes in the attached angle brackets line up with holes going through the rack mounting brackets to the screw holes in the rack posts. Install and tighten the screws to secure the cable manager bulkheads on the rack posts.

Power-on and boot-up

Prerequisites

Install the switch components as described in Installing components.

Procedure

1. Plug the supplied power cords into the AC inlets on the rear panel of the chassis.

NOTE: The Aruba 6400 switches do not have a power switch. They are powered-on when the power cord is connected to the switch and to a power source.

1. Plug the provided power cords into the AC power supplies for your switch. Each power cord should be plugged into a separate, dedicated, properly grounded 20-Amp circuit.

CAUTION: Do not plug multiple power supplies into the same circuit, as it may cause an overload condition.

1. Allow approximately five minutes for the switch to complete the NOS boot-up.

2. After the NOS boot-up completes, verify that the switch is operating properly by observing the LEDs. If you need a reference for interpreting LED behavior, see the Monitoring Guide by visiting the Aruba Support Portal at https://asp.arubanetworks.com/downloads.

Initial management access

Initial configuration of a factory default switch

NOTE: For detailed information on using the following initial configuration methods, see the Fundamentals Guide on the Aruba Support Portal at https://asp.arubanetworks.com/downloads

Use one of the following methods to perform the initial configuration:

- Zero Touch Provisioning (ZTP).

- Wireless connection through a mobile device using Bluetooth and the Aruba CX Mobile App. The wireless connection is achieved by plugging in the Bluetooth dongle to the USB slot, and then connecting using the Aruba CX Mobile application.

NOTE: The Bluetooth dongle is shipped with all Aruba CX switches.

- Connecting with SSH through the switch management port to a computer connected to the same network.

- Connecting the switch console port to a computer running terminal emulation software, and configuring switch settings by executing CLI commands.

Protect the switch and components from damage caused by ESD (Electrostatic discharge)

CAUTION:

• See Grounding the chassis.

• Always wear an ESD wrist strap when handling the switch or its components. Ensure the strap is reliably grounded to an unpainted metal grounding point when installing or removing switch components.

2 ESD wrist strap connection point (grounding lug) on rear panel

- Hold management modules and line modules by their edges. Do not touch any electronic components or printed circuitry.

- Store uninstalled modules in antistatic bags.

Handle your Aruba 6400 Switch components with care. Rough or careless handling can damage the components and result in unplanned down time.

Adding or replacing line modules with controlled shutdown or hot swap methods

Aruba recommends using the CLI to shut down modules before removing them from the switch. This provides a controlled shutdown process that minimizes traffic loss and loss of function. However it also can cause a longer delay in getting the replacement module operational.

IMPORTANT: Unplanned hot swapping of modules is also supported, though it can result in traffic loss and some system interruption. Unplanned line card hot swap is enabled for a single card at a time with at least one minute required between unplanned hot swaps of multiple line cards.

Using controlled shut down to add or replace line modules

If an empty line module slot is in the default configuration state, a module boots up when installed in the slot. If there is a configuration mismatch between an installed module and the slot in which it is installed, the module does not boot up. Use the procedures in this section to bring up a line module in cases where the slot configuration is a mismatch for the line module.

Adding a line module to an empty, unconfigured slot

Prerequisites

• Have an ESD wrist strap ready to use.
• Have available the line module you plan to install in the empty, unconfigured slot. When installing a line module in an unconfigured slot, the module will be brought up as Admin-state up.
• Know the configuration you want on the selected slot.

Procedure

1. Put on a snugly fitting ESD wrist strap and attach it to the ESD connector on the front of the switch. (See Protect the switch and components from damage caused by ESD (Electrostatic discharge).)
2. Remove the blank slot cover from the chosen slot and store it for future use.
3. Install the module. As noted above, installing a line module in an unconfigured slot brings the module up as Admin-state up.

Removing or replacing a line module

NOTE: If you are exchanging one type of line module with a different type in the same slot, or not replacing the module at all, reset the slot to the default configuration by using the no module command. If you are exchanging a line module for another line module of the same type, resetting the slot is not needed. In this case, the existing slot configuration is retained.

IMPORTANT: When removing or installing line modules, make sure to wear a properly installed ESD wrist strap to avoid damage to the line card. See Attaching an ESD wrist strap for more information.

Prerequisites

Have the replacement line module available and ready to install.

Procedure

1. Use the module admin-state down command to bring down the module slot before removing the installed module.

For example, to bring down module slot 1/2:

switch(config)# module 1/2 admin-state down

1. Before removing the module, verify that it is down using the show module command.

For example, to show the module in slot 1/2:

switch(config)# show module 1/2
Line module 1/2 is down: (Administratively down)

Full Description: 6400 24-port SFP+ and 4-port SFP56 Module
Serial number: xxxxxxxxxx
Product number: R0X43A 

1. Loosen the screws securing the line module to the chassis.

2. Open the extractor handles and pull the module out of its slot, placing the module in an antistatic bag for protection from ESD damage.

3. If you do not plan to install another line module in the empty slot, then secure a line module slot cover over the slot opening.

1. To install another line module in the empty slot:

a. Slide the line module part-way into the selected module slot.
b. Open the extractor handles.
c. Push the module into the slot until it stops.

d. Firmly close the extractor handles.

e. Tighten the screws at the top and bottom of the module.

1. If you are replacing the module with a module of a different type, use the no module command to set the slot to its default configuration and then reconfigure the slot for the new module type. See the Fundamentals Guide for more information.

2. If the replacement module is the same type as the original module, use the module admin-state up command to bring up the module slot. The original configuration will be maintained.

For example, to bring up module slot 1/2:

switch(config)# module 1/2 admin-state up

1. Verify that the module successfully booted and is operational using the show module command.

For example, to show the module in slot 1/2:

switch(config)# show module 1/2
Line module 1/2 is up:

Removing or replacing a standby management module

Prerequisites

If you are replacing the standby module, have the replacement available and ready to install.

Procedure

1. Put on an ESD wrist strap and connect it to the ESD connection point on the front of the chassis. (See Attaching an ESD wrist strap.)

2. Identify the standby Management module.

The Stby LED shows a solid green and the Actv LED is dark.

1. Loosen the screws securing the standby module to the chassis.

2. Open the module levers and pull the module out of its slot. To help protect the module from ESD damage, place it in an anti-static bag.

1. If you do not plan to install another management module in the empty slot, then secure a management module slot cover over the slot opening.

2. To install another management module in the empty slot:

a. Slide the management module part-way into the standby Management module slot. (The installed management module showing the lighted Actv LED indicates the active slot).
b. Open the module locking levers.
c. Push the module into the slot until it stops.

d. Firmly close the module locking levers.

e. Tighten the screws at the top and bottom of the module.

Removing or replacing an active management module

NOTE: To remove an active management module, both a standby and an active management module must be installed in the switch. If there is only one management module installed, then install your replacement module as a standby module before performing this procedure. (See Removing or replacing a standby management module.)

To remove the active management module from the switch, first use the redundancy-switchover command to convert the active module to standby and the standby module to active.

Prerequisites

If you are replacing the active management module, have the replacement module available and ready to install.

Procedure

1. Put on an ESD wrist strap and connect it to the ESD connection point on the front of the chassis. (See Attaching an ESD wrist strap.)

2. Identify the active management module. (The Mgmt State Activ LED shows solid green to indicate the active management module.)

3. Using the CLI, execute the redundancy-switchover command to convert the active management module to standby, and the standby management module to active.

For more information on module commands, see the Command-Line Interface Guide.

NOTE: After using the redundancy-switchover command, check the Active and Standby LEDs on both modules to ensure that the Active/Standby conversion took place. If the Standby management module was not available when the command was executed, the conversion fails.

1. Loosen the screws securing the module you converted to Standby in step 3.

2. Open the locking module levers and pull the module out of its slot. Place the module in an antistatic bag for protection from ESD damage.

1. If you do not plan to install another management module in the empty slot, then secure a management module slot cover over the slot opening.

Fan trays are installed in the slots on the rear of the chassis.

CAUTION: Replace only one fan tray at a time. Removing more than one fan tray at a time compromises system cooling, risks damage to the hardware, and can cause the switch to shut down abruptly.

CAUTION: For proper cooling and ventilation, a powered-up 6400 Series chassis must have all fan trays installed and all four fans in each fan tray running.

- Do not remove a fan tray from a powered up switch without having a replacement fan tray available.

- When replacing a fan tray in an operating switch, install the replacement fan tray within two minutes of removing the original fan tray.

- Ensure that all fans in the replacement fan tray are operating after installation.

- If replacing more than one fan tray, ensure each fan tray is correctly installed and operational before removing the next fan tray.

Handle your Aruba 6400 Switch components with care. Rough or careless handling can damage the components and result in unplanned down time.

Basic troubleshooting tips

The following situations cause most problems. Check for these items first when starting your troubleshooting:

• Faulty or loose cables. Look for loose or faulty connections. If they appear to be OK, make sure that the connections are snug. If that does not correct the problem, try a different cable.
• Non standard cables. Non standard and mis-wired cables may cause network collisions and other network problems, and can seriously impair network performance. Use a new, correctly wired cable. For pinouts and correctly wired cable, compare your cable to the cable information in the latest version of the ArubaOS-Switch and ArubaOS Transceiver Guide at https://asp.arubanetworks.com/downloads. A category 5 cable tester is a recommended tool for every 1000Base-T network installation.
• Improper Network Topologies. It is important to ensure that you have a valid network topology. Common topology faults include excessive cable length and excessive repeater delays between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is likely at fault.

In addition, make sure that your network topology contains no data path loops. Between any two end nodes, there must be only one active cabling path at any time. Data path loops cause broadcast storms that severely impact your network performance.

Building redundant paths between important nodes in your network provides some fault tolerance. Before opening redundant paths, enable Spanning Tree Protocol support on the switch. Spanning tree ensures that only one of the redundant paths is active at any time, thus avoiding data path loops. Spanning Tree can be enabled through the switch console or the web browser interface.

The 6400 switches also support Trunking (link aggregation), which allows using multiple network cables for a single network connection without causing a data path loop. For more information, go to https://asp.arubanetworks.com/downloads and see these publications:

- Spanning Tree: Layer 2 Bridging Guide

- Trunking: Link Aggregation Guide

- Using event and debug logs, show tech, and run-time diagnostics. These built-in features can help to isolate the sources of problems. For more information, see the Diagnostics and Supportability Guide at https://asp.arubanetworks.com/downloads.

Functions of the management module reset button

CAUTION: Use a hard reset on a management module only if other methods to recover from a loss of control have failed. Using a hard reset can result in corrupting the file system on the management module SSD (solid state drive). In this case, reformatting the management module SSD is required to recover.

Module Soft reset: Press Reset button for less than five seconds		Hard reset: Press Reset button for five seconds or more
Module "A" Active	Resets management module "A" after a 5-10 second delay for orderly shutdown.Failureover occurs. Module "A" becomes the Standby after it comes back up.Module "B" (the former Standby management module) becomes the new Active management module and maintains switch operation.If there is no Standby management module installed, or if the installed Standby module is inoperative, then the switch goes down while module "A" completes the reset process and resumes operation as the Active management module.	Immediately resets management module "A". There is no shutdown process. This action can result in a loss of data that was currently being processed in module "A".Management module "B" does not reset; becomes the new Active management module.If there is no second module installed, or if the installed second module is inoperative, then the switch goes down while management module "A" completes the reset process and resumes operation.
Module "B" Standby	Resets management module "B" during a 5-10 second reset delay for orderly shutdown.The switch remains up and running.Management module "B" returns to the Standby role when it completes its reset cycle.No effect on the Active management module (Module "A").NOTE: If a condition that causes a failover occurs while Module "B" is still in its reset cycle, a full chassis restart results.	Immediately resets management module B. There is no orderly shutdown process.Management module "B" resumes as the Standby management module after the reset concludes.No effect on the Active management module (Module "A").

NOTE: Using a C16 inlet adapter with a 3000W PSU, or using a C20 inlet adapter with an 1800W PSU is not supported.

System power consumption

To determine the maximum power consumption of an Aruba 6400 switch, determine the quantity of each component installed in the table titled "Component power usage". Multiply the quantity installed by the "Power per component" to determine the total power consumption of each component type. Sum the total of all component types to determine the total maximum power consumption for the system.

Table 13: Base chassis power consumption

Switch SKU and model Included/installed components Power

1 Power is reduced to 2950 at 200VAC nominal. This primarily applies to Japan, as they are the only country with a 200VAC high line. However, the power drop can also occur in other electrical environments where the high line power drops to 200VAC for any reason.

NOTE: Power consumption numbers reflect worst case conditions under maximum traffic loading. In practice actual power consumption is typically less than these limits.

These power consumption limits are used by the management software to determine how much power to allocate for each module. If there is not enough available power for all line cards installed, the management software may not power all cards to stay below the available power.

Power available for PoE: Excess power available from the power supplies beyond the total system and line module allocation is available for PoE powered devices sourced by the line modules.

Redundancy: If power supply or AC grid redundancy is required, add additional power supplies to the system.

Example using an Aruba 6405:

- Installed components:

• Two 1800W PSUs @ 200-240 VAC (high line)
• Two management modules
• All fan trays installed

• System power required: 645W + (4× 113W) + (1× 352W) = 1449W
  • Available power: 2 x 1800W = 3564W (see Table 15: Available power from PSUs installed)
• Excess power available for PoE: 3564W -- 1449W = 2115W
• If power supply redundancy is required:

• Available power comes from one less PSU, which equals 1800W.

- Excess power available for PoE is: 1800W -- 1449W = 351W.
