Chapter 2: Server Installation
Chapter 2
Rack Installation
2-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following these steps in the order given should enable you to have the system
operational within a minimal amount of time.
2-2 Unpacking the System
You should inspect the box which the chassis was shipped in and note if it was
damaged in any way. If the chassis itself shows damage, you should le a damage
claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold your chassis. It should
be situated in a clean, dust-free area that is well ventilated. Avoid areas where
heat, electrical noise and electromagnetic elds are generated. The system needs
to be placed near a grounded power outlet. Be sure to read the Rack and Server
Precautions in the next section.
2-3 Preparing for Setup
The box your chassis was shipped in should include two sets of rail assemblies and
the mounting screws needed for installing the system into the rack. Also included
is an optional square hole to round hole converter bracket, for use in racks with
round mounting holes. Please read this section in its entirety before you begin the
installation procedure outlined in the sections that follow.
Choosing a Setup Location
• Leave enough clearance in front of the rack to enable you to open the front
door completely (~25 inches).
• Leave 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).

2-2
SUPERSERVER 4048B-TR4FT USER'S MANUAL
2-4 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 installations, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure that the rack is stable before extending a component from
the rack.
• You should extend only one component at a time - extending two or more si-
multaneously may cause the rack to become unstable.
General Server Precautions
• Review the electrical and general safety precautions that came with the com-
ponents you are adding to your chassis.
• 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 upwards.
• 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 hard drives and power supply modules to cool before touch-
ing them.
• Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.

2-3
Chapter 2: Server Installation
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (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
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 connec-
tions 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.

SUPERSERVER 4048B-TR4FT USER'S MANUAL
2-5 Rack Mounting Instructions
This section provides information on installing the chassis into a rack unit with the
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 26.5" and 36.4" deep
Identifying the Sections of the Rack Rails
The chassis package includes a rack rail assembly in the rack mounting kit. Each
assembly consists of three sections: An inner chassis rail which 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 specically designed for the left and right
side of the chassis..
Installing the Inner Rails on the Chassis
Installing the Inner Rails
1. Place the inner rails on the side of the chassis aligning the hooks of the chas-
sis with the inner rail holes. Make sure that the rail faces "outward" so that it
will t with the rack's mounting bracket.
2. Slide the rail toward the front of the chassis.
