Chapter 2: Server Installation
2-1
Chapter 2
Server Installation
This chapter provides a quick setup checklist to get your system up and running.
This quick setup assumes that your system has come to you with the processors
and memory preinstalled. If your system is not already fully integrated with a
serverboard, processors, system memory etc., please turn to the chapter or section
noted in each step for details on installing specic components.
2-1 Unpacking the System
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, le a damage claim with the carrier
who delivered it.
2-2 Preparing for Setup
Decide on a suitable location for the rack unit that will hold your chassis. It should
be a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical
noise and electromagnetic elds are generated. A nearby grounded power outlet.
is required
The box your chassis was shipped in should include two sets of rail assemblies, two
rail mounting brackets and the mounting screws to mount the system into the rack.
Please read this chapter in its entirety before beginning the installation procedure.
Choosing a Setup Location
• Leave enough clearance in front of the rack to enable you to open the front door
completely (~25 inches) and approximately 30 inches of clearance in the back
of the rack to allow for sufcient airow and ease in servicing.This product is for
installation only in a Restricted Access Location (dedicated equipment rooms,
service closets and the like).
• This product is not suitable for use with visual display work place devices
acccording to §2 of the German Ordinance for Work with Visual Display Units.

2-2
SUPERSERVER 1028GQ-TXR(T) User's Manual
2-3 Warnings and Precautions
Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to
the oor with the full weight of the rack resting on them.
• In single rack installation, 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 component from the
rack.
• You should extend only one component at a time - extending two or more
simultaneously may cause the rack to become unstable.
• Rack-mounted equipment should not be used as a shelf or work space.
Server Precautions
• Review the electrical and general safety precautions in Chapter 4.
• Determine the placement of each component in the rack before you install the
rails.
• Install the heaviest server components on the bottom of the rack rst, and then
work up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from
power surges, voltage spikes and to keep your system operating in case of a
power failure.
• Allow the hot plug SATA drives and power supply modules to cool before
touching them.
• Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.

Chapter 2: Server Installation
2-3
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 ambient temperature
of the room. Therefore, consideration should be given to installing the equipment
in an environment compatible with the manufacturer’s maximum rated ambient
temperature (Tmra).
Reduced Airow
Equipment should be mounted into a rack so that the amount of airow 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
the 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.).
Warning! 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 lled 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.

rails provided. There are a variety of rack units on the market, which may mean
that the assembly procedure will differ slightly from the instructions provided. You
should also refer to the installation instructions that came with the rack unit you are
using. Note: This rail will t a rack between 27" and 32" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit. 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 that slides in the outer rail.
These assemblies are specically designed for the left and right side of the chassis.

Releasing the Inner Rail
It is necessary to release the inner rail from the middle and outer rails before
installing the inner rail on the chassis.
Releasing the Inner Rail from the Middle and Outer Rails
1. Lift the front latch on the inner rail and pull the inner rail out of the middle rail,
and the middle rail out of the outer rail until the rails are fully extended.
2. Press down the locking lever on the inside of the inner rail to release the inner
rail. Continue to pull the inner rail out of the middle rail.

Installing The Inner Rails on the Chassis
Installing the Inner Rails
1. Conrm that the left and right inner rails have been correctly identied.
2. Place the inner rail rmly against the side of the chassis, aligning the pins on
the side of the chassis with the slotted thru holes in the inner rail.
3. Slide the inner rail toward the rear of the chassis until the pins are at the end of
the narrow slot, which secures the inner rail to the chassis. An optional screw
may be added for extra security.
4. Repeat for the other inner rail.
Warning: Do not pick up the server by the front handles. They are designed
to pull the system from a rack only.
