2-1 Overview
Thischapterprovidesa quicksetupchecklist togetyour SuperServer6028R-WTR(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 SuperServer 6028R-WTR(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 SuperServer
6028R-WTR(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. Read the Rack and
Server Precautions in the next section.
2-3 Preparing for Setup
The box the SuperServer 6028R-WTR(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.

2-2
SUPERSERVER 6027R-73DARF 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) 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.
2-4 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
simultaneously 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 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
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 filled 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.
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating
temperature 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
temperature (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
connections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).

2-4
SUPERSERVER 6027R-73DARF User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the SC815 chassis into a rack unit
with the quick-release 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: This rail will fit a rack between 26" and 33.5" deep.
Warning: Do not pick up the server with the front handles. They are
designed to pull the system from a rack only.
Stability Hazard: The rack stabilizing mechanism must be in place, or the
rack must be bolted to the floor before you slide the unit out for servicing. Failure
to stabilize the rack can cause the rack to tip over.
Warning: Slide rail mounted equipment is not to be used as a shelf or a
work space.
Separating the Sections of the Rack Rails
The chassis package includes two 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.
Installing the Inner Rail Extension
The SC825 chassis includes a set of inner rails in two sections: inner rails and
inner rail extensions. Inner rail extensions are attached to the inner rails to mount
the chassis in the rack.
Installing the Inner Rails
1. Place the inner rail extensions on the side of the chassis aligning the hooks
of the chassis with the rail extension holes. Make sure the extension faces
"outward" just like the pre-attached inner rail.
2. Slide the extension toward the front of the chassis.
3. Secure the chassis with 2 screws as illustrated. Repeat steps for the other
inner rail extension.
