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.).
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.

2.3 Installing the Rails

There are a variety of rack units on the market, which may require a slightly different assembly
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
specific rack you are using.

Identifying the Rails

The rack rails and the related hardware should have been included with the system. Refer to
Figure 2-1 to identify the rail sections. Note that these two rails are left/right specific

Installing the Chassis Rails

Begin the rack mounting procedure by installing the inner rails to the server chassis.
1. Position the front and rear chassis rail sections along the side of the server making sure
the screw holes line up. Note that these two rails are left/right specific.
2. Screw the front chassis rail (the long piece) securely to the side of the chassis (see
Figure 2-2). There should be two screws for each side. Repeat this procedure for the
other rail on the opposite side of the chassis.
3. Attach the two rear chassis rails to the chassis in the same manner, again keeping in
mind that the rails are left/right specific. (You will also need to attach the rail brackets
when installng into a telco rack.)
Slide rail mounted equipment is not to be used as a shelf or a work space.
Warning: do not pick up the server with the front handles. They are designed to pull
the system from a rack only.
