Rack Mounting Instructions

This section provides information on installing the chassis into a rack unit with the
rails provided. There are a variety of rack units on the market, which may mean
that the assembly procedure will differ slightly from the instructions provided. 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 26.5" and 36.4" deep.

Identifying the Sections of the Rack Rails

The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of three sections: An inner chassis rail which secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail which extends
from the outer rail. These assemblies are specifically designed for the left and right
side of the chassis.

Warning: do not pick up the server with the front handles. They are de-
signed to pull the system from a rack only.

Locking Tabs

Each inner rail has a locking tab. This tab locks the chassis into place when installed
and pushed fully into the rack. These tabs also lock the chassis in place when fully
extended from the rack. This prevents the server from coming completely out of
the rack when when the chassis is pulled out for servicing.

Releasing the Inner Rail

Releasing Inner Rail from the Outer Rails
1. Identify the left and right outer rail assemblies as described on page 6-4.
2. Pull the inner rail out of the outer rail until it is fully extended as illustrated
below.
3. Press the locking tab down to release the inner rail.
4. Repeat steps 1-3 for the second outer rail.

Slide rail mounted equipment is not to be used as a shelf or a work space.
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.
