Chapter 2: Server Installation
2-1
Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your 8015C-T 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, processors, 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 8015C-T 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 8015C-T. 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 8015C-T 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.

SUPERSERVER 8015C-T User's Manual
Warnings and Precautions!
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 si-
multaneously 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.
•

•
•
•
•
•
•
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 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
acccording to §2 of the the German Ordinance for Work with Visual Display
Units.

Chapter 2: Server Installation
2-3
Allow the hot plug SATA 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.
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 8015C-T User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the 8015C-T into a rack unit with the
rack rails provided. If the system 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. 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 two rack rail assemblies in the rack mounting kit. Each
assembly consists of two sections: an inner fixed chassis rail that secures directly
to the server chassis and an outer fixed rack rail that secures directly to the rack
itself (see Figure 2-1). Two pairs of short brackets to be used on the front side of
the outer rails are also included.
Installing the Inner Rails
Both the left and right side inner rails have been pre-attached to the chassis. Pro-
ceed to the next step.
Figure 2-1. Identifying the Sections of the Rack Rails
(right side rail shown)

Chapter 2: Server Installation
2-5
Installing the Outer Rails
Begin by measuring the distance from the front rail to the rear rail of the rack. Attach
a short bracket to the front side of the right outer rail and a long bracket to the rear
side of the right outer rail. Adjust both the short and long brackets to the proper
distance so that the rail can fit snugly into the rack. Secure the short bracket to the
front side of the outer rail with two M4 screws and the long bracket to the rear side
of the outer rail with three M4 screws. Repeat these steps for the left outer rail.
Locking Tabs
Both chassis 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.
Figure 2-2. Installing the Rack Rails

2-6
SUPERSERVER 8015C-T User's Manual
Figure 2-3. Installing the Server into a Rack
Installing the Server into the Rack
You should now have rails attached to both the chassis and the rack unit. The next
step is to install the server into the rack. Do this by lining up the rear of the chas-
sis rails with the front of the rack rails. Slide the chassis rails into the rack rails,
keeping the pressure even on both sides (you may have to depress the locking
tabs when inserting). See Figure 2-3.
When the server has been pushed completely into the rack, you should hear the
locking tabs "click". Finish by inserting and tightening the thumbscrews that hold
the front of the server to the rack.
