2-5Installing the Chassis Rails
Position the fi xed chassis rail sections you just removed along the side of the
chassis so that the three screw holes line up with the corresponding holes on the
chassis. Note that these two rails are left/right specifi c. Screw the rail securely to
the side of the chassis (see Figure 2-2) with the screws provided in the rackmount
kit. Repeat this procedure for the other rail on the other side of the chassis. You
will also need to attach the rail brackets when installing into a telco rack.
Locking Tabs: As you have seen, both chassis rails have a locking tab, which
serves two functions. The fi rst is to lock the server into place when installed and
pushed fully into the rack, which is its normal position. Secondly, these 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 you pull it out for servicing.
Figure 2-2. Installing Chassis Rails
also refer to the installation instructions that came with the rack unit you are using.
Be aware that there are a variety of rack units on the market, which may mean the
assembly procedure will differ slightly.
The two rail sections must be detached from each other prior to installation. Do
this by depressing the locking tab on the inner rail to release it from its locked
