Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your SuperServer 7045B-8R+/
7045B-TR+ 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.
The 7045B-8R+/7045B-TR+ may be employed either as a tower or mounted in a
rack as a 4U rackmount chassis. If using it as a tower unit, please read the Server
Precautions in the next section and then skip ahead to Section 2-5.
2-2 Unpacking the System
You should inspect the box the system 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 SuperServer 7045B-8R+/7045B-TR+. 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. Be sure to read the Rack and Server
Precautions in the next section.
2-3 Preparing for Setup
The box the system was shipped in may include two sets of rail assemblies, two
rail mounting brackets and mounting screws needed for installing the system into a
rack (optional kit). 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 7045B-8R+/7045B-TR+ User's Manual
Choosing a Setup Location
- Leave enough clearance in front of the system to enable you to open the front
door completely (~25 inches).
- Leave approximately 30 inches of clearance in the back of the system 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 according
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 SCSI/SATA 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.).

SUPERSERVER 7045B-8R+/7045B-TR+ User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the system into a rack unit. Rack
installation requires the use of the optional rackmount kit. If the system has already
been mounted into a rack or if you are using it as a tower, 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 server into a rack with the rack rails provided in the rackmount kit.
You should also refer to the installation instructions that came with the rack unit
you are using.
Identifying the Sections of the Rack Rails
The optional rackmount kit includes two rack rail assemblies. Each of these as-
semblies consist of three sections: an inner fixed chassis rail that secures to the
chassis, an outer rack rail that secures directly to the rack itself and two rail brackets,
which also attack to the rack (see Figure 2-1.) The inner and outer rails must be
detached from each other to install.
To remove the inner chassis rail, pull it out as far as possible - you should hear a
"click" sound as a locking tab emerges from inside the rail assembly and locks the
inner rail. Depress the locking tab to pull the inner rail completely out. Do this for
both assemblies (one for each side).
