Chapter 2

Rack Mount Installation

2.1 Overview

This chapter provides instructions for preparing and mounting your chassis in a rack. By default, the chassis is shipped configured as a tower. The tower top cover and bottom feet must be removed to mount in a rack. Also, the control panel/drive module should be rotated 90 degrees.

Mounting rails are optional for this system. Be sure you have received the correct rail kit for your server.

2.2 Preparing for Rack Mounting

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 at least 25 inches clearance in front of the rack to open the front door completely.
• Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient airflow and access for servicing.
• It should be a restricted access location, such as a dedicated equipment room or a service closet.
• 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.

• You should 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.

Server Precautions

• Review the electrical and general safety precautions in Appendix B.
• 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.

2.3 Chassis Preparation

The chassis is shipped with the tower top cover and feet installed. Both must be removed for before installing the rails.

Removing the Tower Top Cover

1. Locate the chassis cover lock (blue lever) at the rear of the chassis cover.
2. Slide the chassis cover lock to the right and push chassis cover forward.
3. Lift the chassis top cover off the chassis.

Tower Top Cover Chassis Feet Chassis Cover Lock

Figure 2-1. Remove Feet and Chassis Top Cover

Removing the Chassis Feet

1. Place the chassis on its side.
2. Remove the screw holding a chassis foot in place.
3. The foot lock is a tab located in the center of the foot. It prevents the foot from sliding. Using a flat head screwdriver, gently lift the foot lock upward and slide the foot toward the rear of the chassis.

2.4 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" and 35.9" 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 optional rackmount kit includes two rack rail assemblies, one for each side. Each of these assemblies consist of several sections: an inner fixed rail that secures to the chassis, an outer rack rail that secures to the rack, a middle rail that slides within the outer rail, and two brackets that attach the outer rail to the rack. The brackets are specific to the left and right side, and front and back, and labeled.

Outer rail Inner rail Rail brackets

Figure 2-2. Identifying the Sections of the Rack Rails

Releasing the Inner Rails

The inner rails must be removed from the outer rails to install onto the chassis. To remove the inner rail, pull it out as far as possible until it clicks to a stop. Depress the locking lever on the inner rail next to the middle rail to pull the inner rail completely out.

Installing the Inner Rails

Identify the left and right inner rails.

1. Attach the handles to the front sides of the chassis with three screws each.
2. Position the inner rails along the side of the chassis making sure the screw holes line up.
3. Screw the rail securely to the side of the chassis.

Screw for Handles Screw for Inner Rails

Figure 2-3. Installing the Chassis Rails

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

Assembling and Installing the Outer Rails

Each outer rail comes in three sections that require assembly before mounting onto the rack.

1. Find the outer rail mounting brackets in the chassis accessory box.

• A pair of long brackets for the rear of each rail

• A pair of short brackets for the front of each rail

Note that the brackets are labeled as to front, rear, and up. They are specific for the left and right rails.

1. Secure the front (short) bracket onto the outer rail with M5 screws.
2. Mount the rear (long) bracket onto the outer rail at the approximate position to fit your rack. Use two or three M5 screws into holes that are convenient. Leave the screws just loose enough that the bracket can slide.
3. Install the outer rail assembly onto your rack. Adjust the outer rail to the exact depth of the rack by sliding the rear bracket. Then use screws and fasteners to secure the outer rail to the front and rear rack posts.
4. Further tighten the screws holding the rear bracket to the rail.

Screw for Outer Rail Brackets

Figure 2-4. Assembling the Outer Rails

2.5 Installing the Server into the Rack

After attaching rails to both the chassis and the rack, slide the server into the rack.

1. Pull the middle rail out of the front of the outer rail and make sure that the ball bearing shuttle is locked at the front of the middle rail.
2. Align the rear of the inner (chassis) rails with the front of the outer (rack) rails and slide the inner rails into the outer rails until the server is completely in the rack.
3. Insert and tighten the thumbscrews that hold the front of the server to the rack.

Inner Rails Outer Rail Assemblies

Figure 2-5. Installing the Server into a Rack

Note: Figure is for illustrative purposes only. Always install servers to the bottom of a rack first.

Warning: 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.

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. Pull the chassis forward out the front of the rack until it stops.
2. Find the release lever on each side of the chassis on the inner rails. Release the chassis by simultaneously and lifting the left lever and pushing down the right lever. Continue to pull the chassis out of the rack.

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

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

2.6 Control Panel Orientation

The server can be configured for either tower or server rack orientation. It is shipped in tower mode and can be immediately used as desktop server. To use it in a rack, rotate the module that contains the control panel and the three drive trays ( ① in Figure 2-6) 90 degrees.

Note that two of the 5.25" drives may be replaced by a mobile rack containing eight 2.5" storage drives.

Caution: Use caution when working around the backplane. Do not touch the module backplane with any metal objects and make sure no ribbon cables touch the backplane or obstruct the holes, which aid in proper airflow.

Chapter 3

Maintenance and Component Installation

This chapter provides instructions on installing and replacing main system components. To assure compatibility, only use components that match the specifications or part numbers given. Installation or replacement of most components require that power first be removed from the system.

3.1 Removing Power

Use the following procedure to ensure that power has been removed from the system. This step is necessary when removing or installing non-hot-swap components.

1. Use the operating system to power down the system.
2. After the system has completely shut down, disconnect both the AC power cords from the power strip or outlet.
3. Disconnect the power cords from both the power supply modules.

3.2 Accessing the System

The chassis offers a removable side cover (top, if rack mounted) which allows access to the internal components.

Removing the Side Cover

1. Locate the latch on the cover, depress where it says "push," then lift the latch to release the cover.
2. Slide the cover to the rear and off.

Figure 3-1. Removing the Chassis Cover

3.3 Chassis Components

Storage Drives

The standard system provides hot-swap drive bays for eight 3.5" SATA drives covered by the front bezel. Alternatively, each bay can house a 2.5" SATA drive with an optional converter (pn MCP-220-00080-0B). The drive IDs for these bays are preconfigured as 0 through 7 from bottom to top.

The drives are hot-swappable, meaning they can be removed and replaced without powering down the system, if that capability is supported by your operating system. The drives are mounted in drive carriers to simplify their installation and removal from the chassis. The carriers also promote airflow for the system. For this reason, even carriers without drives must remain in the server.

There are several options that provide additional SAS or SATA storage drives if an optional SAS RAID controller card is purchased. Each 5.25" bay can house one 3.5" drive, or two 2.5" drives with a bracket. Or two 5.25" bays can be replaced by an optional enclosure called a mobile rack that houses eight hot-swap 2.5" drives. Additional cables are also required.

Note: Enterprise level hard disk drives are recommended for use in Supermicro chassis and servers. For information on recommended HDDs, visit the Supermicro website at http://www.supermicro.com/products/nfo/files/storage/SBB-HDDCompList.pdf.

Drive Indicators

Each hot-swap drive has two LED indicators: an activity indicator and a status indicator. In RAID configurations, the status indicator lights to indicate the status of the drive. In non-RAID configurations, the status indicator remains off. See the table below for details.

Drive Carrier LED Indicators
	Color Blinking Pattern Behavior for Device
Activity LED	Off No drive, or SATA drive installed
	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

To modify the operation of the backplane, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin 1 is identified with a square solder pad on the printed circuit board. Note: On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.
