Chapter 2

Installation in a Rack

This chapter provides advice and instructions for mounting your system in a rack.

2.1 Preparing for Setup

The box in which the system was shipped should include the hardware needed to install it into the rack. Please read this section in its entirety before you begin the installation.

Choosing a Setup Location

• The system should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated.
• Leave enough clearance in front of the rack so that you can open the front door completely (\~25 inches) and approximately 30 inches of clearance in the back of the rack to allow sufficient space for airflow and access when servicing.
• This product should be installed only in a Restricted Access Location (dedicated equipment rooms, service closets, etc.).
• This product is not suitable for use with visual display workplace devices according to §2 of the German Ordinance for Work with Visual Display Units.

Rack Precautions

• Ensure that the leveling jacks on the bottom of the rack are extended to the floor so that the full weight of the rack rests on them.
• In single rack installations, stabilizers should be attached to the rack. In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a server or other component from the rack.

• Extend only one server or component at a time - extending two or more simultaneously may cause the rack to become unstable.

• When initially installing the server to a rack, test that the rail locking tabs engage to prevent the server from being overextended. Have a rack lift in place as a precaution in case the test fails.

• In any instance of pulling the system from the rack, always use a rack lift and follow all associated safety precautions.

Server Precautions

• Review the electrical and general safety precautions in Chapter.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components at the bottom of the rack first and then work your way up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any drives and power supply modules to cool before touching them.
• When not servicing, always keep the front door of the rack and all covers/panels on the servers closed to maintain proper cooling.

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the room's ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature (Tmra).

Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of power strips, etc.).

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
• Slide rail mounted equipment is not to be used as a shelf or a work space.

2.2 Installing the Rails

There are a variety of rack units on the market, which may require a slightly different assembly procedure. Do not use a two post "telco" type rack. This rail set fits a rack between 26.5" and 36.4" deep.

The following is a basic guideline for installing the system into a rack with the rack mounting hardware provided. You should also refer to the installation instructions that came with the specific rack you are using.

Identifying the Rails

The chassis package includes two rail assemblies. Each assembly consists of three sections: An inner rail that secures directly to the chassis, an outer rail that secures to the rack, and a middle rail which extends from the outer rail. These assemblies are specifically designed for the left and right side of the chassis and labeled.

Figure 2-1. Identifying the Outer Rail, Middle Rail and Inner Rail (Left Rail Assembly Shown)

Releasing the Inner Rail

Each inner rail has a locking latch. This latch prevents the server from coming completely out of the rack when when the chassis is pulled out for servicing.

To mount the rail onto the chassis, first release the inner rail from the outer rails.

1. Pull the inner rail out of the outer rail until it is fully extended as illustrated below.
2. Press the locking tab down to release the inner rail.
3. Pull the inner rail all the way out.

Figure 2-2. Extending and Releasing the Inner Rail

Installing the Inner Rails

Begin the rack mounting procedure by installing the inner rails to the chassis.

1. Identify the left and right inner rails. They are labeled.
2. Place the inner rail firmly against the side of the chassis, aligning the angled posts on the side of the chassis with the holes in the inner rail.
3. Slide the inner rail forward toward the front of the chassis and under the angled posts until the rail lock snaps into place, securing the rail to the chassis.
4. If desired, secure the rail with a locking screw.

Figure 2-3. Installing the Rails

Warning: Do not pick up the server with the front handles. They are designed to pull the system from a rack only.

Installing the Outer Rails onto the Rack

1. Press upward on the locking tab at the rear end of the middle rail.
2. Push the middle rail back into the outer rail.
3. Hang the hooks on the front of the outer rail onto the square holes on the front of the rack. If desired, use screws to secure the outer rails to the rack.
4. Pull out the rear of the outer rail, adjusting the length until it just fits within the posts of the rack.
5. Hang the hooks of the rear section of the outer rail onto the square holes on the rear of the rack. Take care that the proper holes are used so the rails are level. If desired, use screws to secure the rear of the outer rail to the rear of the rack.
6. Repeat for the other outer rail.

Figure 2-4. Extending and Mounting the Outer Rails

Adapters for Round and Threaded Hole Racks

The chassis includes adapter brackets for those customers using round hole racks or racks with threaded holes size M5 or larger.

Installing the Outer Rails with Adapter Brackets

1. Place the hooks of the front of the outer rail into the square holes of one of the adapter brackets.
2. Place the hooks of the rear of the outer rail into the square holes of a second adapter bracket.
3. Adjust the length of the outer rail to fit within the rack uprights.
4. Secure the front adapter bracket to the front of the rack using the screws recommended by the rack manufacturer.
5. Secure the rear adapter bracket to the rear of the rack in the same manner.

2.3 Installing the Chassis into a Rack

After the rails are installed on the chassis and on the rack, the server can be installed in the rack. It is heavy and requires two to three people or a lift.

Installing the Chassis into a Rack

1. Pull both middle rails out the front of the outer rail until each clicks to a stop.
2. Align the inner rails on the chassis with the front of the middle rails.
3. Slide the inner rails on the chassis into the middle rails, keeping the pressure even on both sides. When partially in, the locking levers will stop further progress.
4. Press down the locking levers on the inside of the inner rails and push the chassis all the way into the rear of the rack. The front latches will click into place.

Note: Figures are for illustrative purposes only. Your actual chassis may differ. Always install servers into racks from the bottom up.

Figure 2-5. Installing the Chassis into the Rack

Warning: When initially installing the server to a rack, test that the rail locking tabs engage to prevent the server from being overextended. Have a rack lift in place as a precaution in case the test fails.

Removing the Chassis from the Rack

Caution! It is dangerous for a single person to off-load the heavy chassis from the rack without assistance. Be sure to have sufficient assistance supporting the chassis when removing it from the rack. Use a lift.

1. Lift the release levers and pull the chassis out the front of the rack until it stops.
2. Press the release latches on each of the inner rails downward simultaneously and continue to pull the chassis completely out of the rack.

Figure 2-6. Removing the Chassis From the Rack

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Slide rail mounted equipment is not to be used as a shelf or a work space.

2.4 Optional Quick Installation Method

The following quick installation method may be used to install the chassis to a rack.

Installing the Chassis into a Rack

1. Install the whole rail assembly into the rack in a manner similar to that described in the previous section, "Installing the Outer Rails onto the Rack."
2. Fully extend the inner rails.
3. Using a lift, carefully align the chassis between the inner rails.
4. Install the inner rails on the chassis in a manner similar to that described in the previous section, "Installing the Inner Rails."

2.4 Installing the Cable Management Arm

The SC946L JBOD chassis supports a cable management arm (CMA) that keeps the rear cables organized and clear of the rail mechanisms when the system is extended out the front of the rack for maintenance. The kit includes six fabric Velcro cable ties.

The CMA attaches to the rack mounting rails by means of four connectors. They are labeled on the connectors 1, 2, 3, and 4.

Figure 2-7. Cable Management Arm and Velcro Straps

Installing the Cable Management Arm

1. Slide CMA connector #1 forward onto the two posts on the rear of the right inner rail (right side when viewed from the front). It snaps into place.
2. Slide CMA connector #2 forward onto the two posts on the rear of the right middle rail. It snaps into place.

Figure 2-8. Installing the Connectors 1 and 2

1. Slide CMA connector #3 forward onto the two posts on the rear of the left middle rail. It snaps into place.

2. For CMA connector #4, align the metal tabs with the slots on the rear of the left outer rail and push it forward. It snaps into place.

Figure 2-9. Intalling the Connectors 3 and 4

Figure 2-10. Routing the Cables

1. Open the four red plastic caps and route the cables into the wire carrier.
2. If necessary, adjust the U-brackets to clear chassis components.

Figure 2-11. Adjusting the U-Brackets

1. Use the six Velcro straps to secure the cables to the CMA. Use a strap on either side of each joint and one on each U-bracket, inserting it through the slot on the bracket.
2. Slide the chassis forward and backward in the rack to confirm that the cable management arm is operating smoothly. If necessary, loosen the straps for smoother movement.

If at some time you must remove the cable management arm, follow this procedure.

Removing the Cable Management Arm

1. Remove cables from the CMA, releasing the Velcro straps and the red plastic caps.
2. For CMA connector #4, pull the metal release tab toward the center of the rack and slide the connector toward the rear to release it.
3. For CMA connectors #3, #2, and #1, depress the front edge of the yellow plastic rocker lock, and slide the connector toward the rear to release it.

After a Power Loss

The system will power up automatically approximately fifteen seconds after the power returns.

Power Down

1. Hold down the power button. The blue Information LED will begin blinking. Continue to hold the power button.
2. Release power button after blue LED stops blinking and goes dark.
3. The shutdown sequence will begin and shut down the system within ten seconds

Removing Power from the System

Before performing most setup or maintenance tasks, use the following procedure to ensure that power has been removed from the system.

1. After the system has completely shut-down, carefully grasp the head of the power cord and gently pull it out of the back of the power supply. If your system has dual power supplies, remove the cords from both power supplies.

2. Disconnect the cord from the power strip or wall outlet.

3.2 Cable Connections

IPMI

The SC946L JBOD chassis offers intelligent management with IPMI to provide hardware health monitoring and remote power control. To enable, connect to the storage enclosure using the dedicated IPMI LAN connector (Figure 1-3).

The default IP address configuration mode is DHCP (Dynamic Host and Configuration Protocol). When connected to the network, you can find the IP address assigned to this system from DHCP server. You can now connect using the User name and Password as shown below.

Note: The IP configuration mode can be toggled between DHCP and Static IP. Press and hold the reset button on the front panel for 6-8 seconds to change to static IP mode with the default IP address as shown below. Press and hold the reset button for 10-12 seconds to change the IP configuration mode back to DHCP.

Simple setup configuration:

IPMI default IP: 192.168.1.99

User name: ADMIN

Password: ADMIN

For details on configuring and using IPMI, refer to the Supermicro IPMI manual.

SAS Cables

This drawing shows connectors for SAS cabling. For primary and secondary, the top two connectors are marked In, and the bottom two connectors are marked In/Out.

Connect two mini-SAS HD cables (SFF-8644) from the head server node host bus adapter (HBA) card to the top two Primary receptacles marked In. If using the E2C model for redundancy, connect two more mini-SAS HD cables to the top two Secondary receptables also marked In. Cables are described in Appendix B.

To cascade out, connect cables from the two receptacles marked In/Out to the next JBOD storage enclosure. (see Figure 3-2 and 3-3)

3.3 Accessing the Chassis

Drive bays can be accessed by opening the top cover. Other components can be accessed though the front or rear of the chassis.

Caution: Except for short periods of time, do not operate the server without the cover in place. It helps provide proper airflow and prevent overheating.

Opening the Drive Cover

On the right side of the chassis, release the two thumb screws and lift the cover. The cover holds an open position at 100 degrees without additional support. Do not open farther.

Figure 3-4. Opening the Drive Cover

3.4 Chassis Components

Hard Drives

The SC946L JBOD chassis supports forty five 3.5" hard drives. They can be removed without powering down the system if your operating system supports RAID. In addition, it supports two 2.5" drives accessible at the rear of the chassis.

Hard Drive Carrier Indicators

Each hard drive carrier has two LED indicators: an activity indicator and a status indicator. The status indicator functions in RAID configurations. For non-RAID configurations, it remains off. See the table below for details.

Hard Drive Carrier LED Indicators
	Color Blinking Pattern Behavior for Device
Activity LED	Blue Solid On SAS drive installed
	Blue Blinking I/O activity
Status LED	Red Solid On Failure of drive with RSTe support
	Red Blinking at 1 Hz Rebuild drive with RSTe support
	Red Blinking with two blinks and one stop at 1 Hz		Hot spare for drive with RSTe support
	Red On for five seconds, then off		Power on for drive with RSTe support
	Red Blinking at 4 Hz Identify drive with RSTe support

Note: Enterprise level hard disk drives are recommended for use in Supermicro chassis and servers. For information on recommended HDDs, visit the Supermicro website and check the "Drive Options" in the product webpage.

Hard Drive Installation

The drives are mounted in drive carriers to simplify their installation and removal from the chassis. These carriers also help promote proper airflow through the drive bays.

Removing Hard Drive Carriers from the Chassis

1. Open the top front cover of the chassis.
2. Slide the release button on the drive carrier, which opens the carrier handle.
3. Use the drive carrier handle to pull the drive out of the chassis.

Figure 3-5. Removing a Hard Drive Carrier

Caution: Except for short periods of time, such as swapping hard drives, do not operate the server with the hard drive bays empty.

Installing a 3.5" Hard Disk Drive

With the drive carrier removed from the storage compartment:

1. Under the main the carrier handle, find and the lift the breakout lever and pull out the side of the carrier.

Figure 3-6. Opening the Drive Carrier

1. Remove the dummy drive from the carrier.

2. Insert the hard drive into the drive carrier. Orient the drive by matching the two alignment pins on the side and by noting the notch in the carrier for the HDD connectors. Close the side of the carrier until it snaps in place.

3. Slide the carrier assembly into its spot in the chassis until it clicks into locked position.

System Cooling

Five hot-swap, heavy-duty rear mounted fans provide cooling. They can be replaced without powering down the system.

Fan speed is controlled by a system temperature setting in IPMI. If a fan fails, the remaining fans will ramp up to full speed. Replace any failed fan at your earliest convenience with the same type and model. The system can continue to run with a failed fan.

Replacing a System Fan

1. While the power is running, examine the fans to determine which fan has failed.
2. Simultaneously press down on the upper release tab and push up the lower release tab of the failed fan.

Figure 3-8. Fan Release Tabs

1. Pull the fan out of the bay using the tabs.

Caution: Fans will continue to rotate for a brief time after removing them from the chassis. To avoid injury, keep fingers clear of the rotating fan blades.

1. Place the new fan into the vacant fan bay. Confirm that the fan is fully seated in the fan bay and functioning properly.

Checking the Server Air Flow

• Make sure there are no objects to obstruct airflow in and out of the server.
• If you are using a front bezel, make sure the bezel filter is replaced periodically.
• Do not operate the server without drives or drive trays in the drive bays.
• Use only recommended server parts.
• Make sure no wires or foreign objects obstruct air flow through the chassis. Pull all excess cabling out of the airflow path or use shorter cables.

The control panel LEDs display system heat status. See “Control Panel” in Chapter 1 for details.

Overheating

There are several possible responses if the system overheats.

Overheat Temperature Setting

Some backplanes allow the overheat temperature to be set at 45, 50, or 55 by changing a jumper setting. For more information, consult the backplane user manual at www.supermicro.com. (Click Support, then the Manuals link.)

Responses

If the enclosure overheats:

1. Use the LEDs to determine the nature of the overheating condition.
2. Confirm that the chassis covers are installed properly.
3. Make sure all fans are present and operating normally.
4. Check the routing of the cables.

Power Supply

The chassis features redundant power supplies. The system will continue to operate if one module fails. It should be replaced as soon as convenient. The power supply modules are hot-swappable, meaning they can be changed without powering down the system. New units can be ordered directly from Supermicro or authorized distributors.

These power supplies are auto-switching capable. This feature enables them to automatically sense the input voltage and operate at a 100-120v or 180-240v.

Power Supply LEDs

On the rear of the power supply module, an LED displays the status.

• Solid Green: When illuminated, indicates that the power supply is on.
• Solid Amber: When illuminated, indicates the power supply is plugged in and turned off, or the system is off but in an abnormal state.
• Blinking Amber: When blinking, this system power supply temperature has reached 63C. The system will automatically power-down when the power supply temperature reaches 70C and restart when the power supply temperature goes below 60C.

Changing the Power Supply Module:

1. Unplug the AC cord from the module to be replaced.
2. On the back of the module, push the release tab sideways, as illustrated.
3. Pull the module out using the handle.
4. Push the new power supply module into the power bay until it clicks. Replace with the same model.
5. Plug the AC power cord back into the module.

There are several procedures to turn on or off the system with the CB3 JBOD control board.

Power Up

First Use or Power Cord Plug-In

1. Plug the power cords into the rear of the power supplies.
2. Wait until blue Information LED starts to blink.
3. Press the power button once. The JBOD control board initiates the power up sequence in three seconds.

After Normal Shutdown by IPMI or Power Button

Press the power button once. The JBOD control board will initiate the power up sequence in three seconds.

After a Power Loss

The system will power up automatically approximately fifteen seconds after the power returns.

Power Down

1. Hold down the power button. The blue Information LED will begin blinking. Continue to hold the power button.
2. Release power button after blue LED stops blinking and goes dark.
3. The shutdown sequence will begin and shut down the system within ten seconds

D.6 IPMI Static IP to DHCP Setting

IP Address to DHCP Setting

1. Download the utility from the Supermicro website or technical support.
2. Extract the file to a known folder.
3. By default, the JBOD control board will be configured in static IP 192.168.1.99.
4. Change the host to static IP as 192.168.1.10.
5. Go to the IPMI website and select the Configuration tab and then select the Network page.
6. Change the setting from Static to DHCP mode

If default website is not responding, press the reset button for more than ten seconds to reset to default. You will observe that the fan speed will slow and then return to normal. Continue to change to DHCP mode when the fan reaches normal speed.

1. Save the new setting.
2. Change the host IP back to DHCP mode.
3. Determine the DHCP IP address of the host, for example 10.1.1.50.
4. Run the command prompt with administrative privileges.
5. Go to the utility folder and type:

findit 00-25-90-xx-xx-xx yy.zz.255.255

Where: xx-xx-xx is, enter the JBOD control board MAC ID. yy.zz represents the first two octets of your host IP. Example: findit 00-25-90-xx-xx-xx 10.1.255.255

1. The utility will return the IP address of the JBOD control board. Enter the IP in browser and access the IPMI web GUI.
