Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your SuperStorage 5018D2-
AR12L/5018D4-AR12L/5018D8-AR12L 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.
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 le a damage claim with
the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the system. 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. 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 5018D2-AR12L/5018D4-AR12L/5018D8-AR12L 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.
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).

2-2
SUPERSTORAGESYSTEM 5018D2-AR12L/D4-AR12L/D8-AR12L User's Manual
• 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.
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 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 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 any hot plug 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 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.

2-5 Installing the System into a Rack
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
the assembly procedure will differ slightly. You should also refer to the installation
instructions that came with the rack unit you are using.
Note: These rails will t a rack between 25.6" and 33" deep.
Installing the Chassis into a Standard Rack
The chassis package includes two sets of rack rails, one set for the right side of the
chassis and one for the left. Each set consists of an inner rail that is xed directly
to the chassis and an outer rail that attaches to the rack.
The inner rails are pre-attached and do not interfere with normal use of the chassis
if you decide not to install it into a rack.
Figure 2-1. Identifying the Sections of the Rack Rails
Warning: do not pick up the server with the front handles. They are de-
signed to pull the system from a rack only.
