Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your SuperServer 6025B-TR+/
6025B-8R+ up and running. Following these steps in the order given should enable
you to have the system operational within a minimum amount of time. 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, pro-
cessors, system memory etc., please turn to the chapter or section noted in each
step for details on installing specific components.
2-2 Unpacking the System
You should inspect the box the SuperServer 6025B-TR+/6025B-8R+ was shipped
in and note if it was damaged in any way. If the server itself shows damage you
should file a damage claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the SuperServer
6025B-TR+/6025B-8R+. It should be situated in a clean, dust-free area that is well
ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are
generated. You will also need it placed near a grounded power outlet. Read the
Rack and Server Precautions in the next section.
2-3 Preparing for Setup
The box the SuperServer 6025B-TR+/6025B-8R+ was shipped in should include
two sets of rail assemblies, two rail mounting brackets and the mounting screws
you will need to install the system into the rack. Follow the steps in the order
given to complete the installation process in a minimum amount of time. Please
read this section in its entirety before you begin the installation procedure outlined
in the sections that follow.

2-2
SUPERSERVER 6025B-TR+/6025B-8R+ User's Manual
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 sufficient airflow 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 ac-
cording to §2 of the the German Ordinance for Work with Visual Display Units.
Rack Precautions
- Ensure that the leveling jacks on the bottom of the rack are fully extended to the
floor 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 simul-
taneously may cause the rack to become unstable.
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 first, 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/SCSI drives and power supply units 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.

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 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 connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).

2-4 Installing the System into a Rack
This section provides information on installing the SuperServer 6025B-TR+/6025B-
8R+ into a rack unit. If the 6025B-TR+/6025B-8R+ has already been mounted into
a rack, you can skip ahead to Sections 2-5 and 2-6. There are a variety of rack
units on the market, which may mean the assembly procedure will differ slightly.
The following is a guideline for installing the system into a rack with the rack rails
provided. You should also refer to the installation instructions that came with the
rack unit you are using.
Identifying the Sections of the Rack Rails
You should have received a total of six rack rail sections with the SuperServer
6025B-TR+/6025B-8R+. Two of these sections secure directly to the 6025B-TR+/
6025B-8R+ and the third (which actually consists of two joined sections) secures
directly to the rack itself. All screws and hardware mentioned in the installation
steps should be included in the hardware kit.
Refer to Figure 2-1 to determine which rail section gets attached to the front of the
chassis and which gets attached to the rear of the chassis. (The longer of the two
is the front section. The third rail section attaches to the rack.)
Installing the Chassis Rails
Position the front and rear chassis rail sections along the side of the 6025B-
TR+/6025B-8R+ making sure the screw holes line up. Note that these two rails
are left/right specific. Screw the front chassis rail (the long piece) securely to the
side of the chassis (see Figure 2-1, step 1). There should be two screws for each
side. Repeat this procedure for the other rail on the opposite side of the chassis.
Then attach the two rear chassis rails to the chassis in the same manner, again
keeping in mind that the rails are left/right specific. (You will also need to attach
the rail brackets when installng into a telco rack.)
Locking Tabs: Both front chassis rails and the rack rails have a locking tab, which
serves two functions. The first is to lock the server into place when installed and
pushed fully into the rack, which is its normal position. Secondly, these tabs also
lock the server in place when fully extended from the rack. This prevents the server
from coming completely out of the rack when you pull it out for servicing.
