Server Installation
2.1 Overview
This chapter provides advice and instructions for mounting your system in a server rack.
If your system is not already fully integrated with processors, system memory etc., refer to

Caution: Electrostatic Discharge (ESD) can damage electronic components. To prevent such
damage to PCBs (printed circuit boards), it is important to use a grounded wrist strap, handle
all PCBs by their edges and keep them in anti-static bags when not in use.
2.2 Preparing for Setup
The box in which the system was shipped includes the rackmount hardware needed to install
it into the rack. Please read this section in its entirety before you begin the installation.
Choosing a Setup Location
• The system should be situated in a clean, dust-free area that is well ventilated. Avoid areas

• In single rack installations, stabilizers should be attached to the rack. In multiple rack in-
stallations, the racks should be coupled together.
• Always make sure the rack is stable before extending a server or other component from
the rack.
• You should extend only one server or 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 Appendix B.
• Determine the placement of each component in the rack before you install the rails.

• Use a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any drives and power supply modules to cool before touching them.
• When not servicing, always keep the front door of the rack and all covers/panels on the
servers closed to maintain proper cooling.
Rack Mounting Considerations
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 room's ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (TMRA).

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.

Chapter 2: Server Installation
19
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.).

procedure.
The following is a basic guideline for installing the system into a rack with the rack mounting
hardware provided. You should also refer to the installation instructions that came with the

Separating the Inner and Outer Rails
1. Locate the rail assembly in the chassis packaging.
2. Extend the rail assembly by pulling it outward.
3. Press the quick-release tab.
4. Separate the inner rail extension from the outer rail assembly.
Warning: do not pick up the server with the front handles. They are designed to pull
the system from a rack only.
Slide rail mounted equipment is not to be used as a shelf or a work space.
