2: Server Installation
Outer Rack Rails
Outer rails attach to the rack and hold the chassis in place. The outer rails for the chassis extend
between 30 inches and 33 inches.
Install the Outer Rails to the Rack
1. Measure the depth of the rack (distance from the front rail to the rear rail) to ensure it
complies with the limitations listed in the previous subsections.
2. 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 (see Figure 2-1 on page 13 ).
3. Adjust both the short and long brackets to the proper distance so that the rail can fit snugly
into the rack.
4. 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.
5. Repeat the previous steps to properly install the left outer rail.
The Inner Rail Extension
The chassis includes a set of factory-installed inner rails in two sections: inner rails and inner rail
extensions. The inner rails are pre-attached to the chassis, and do not interfere with normal use of
the chassis if you decide not to use a server rack. The inner rail extension is attached to the inner
rail to mount the chassis in the rack.
Using the Rail Locking Tabs
Both chassis rails have a locking tab, which serves two functions:
• The tabs can lock the server into place when installed and pushed fully into the rack, (its
normal operating position).
• The 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 pulled out for servicing.
Depress both tabs at the same time to fully remove the server from its rail mounting and extract it
from the rack.
