3.16 Chassis Rail Installation (Universal Rails)

WARNING

Use care in supporting the chassis rail assembly. It is heavy and

awkward to position within the cabinet. If possible, use two persons

to support and position the chassis rail assembly. The chassis rail

assembly may cause personnel injury and equipment damage if

dropped during installation.

Note

To be sure of proper alignment of the chassis rail assembly, use care to

position the round standoffs in the correct front and rear chassis rail

locating holes.

3. From the rear of the cabinet, position the chassis rail assembly at the

correct mounting holes, as shown. Be sure that the rail bracket is

positioned toward the rear of the cabinet, and that the arrow on the

rail bracket points up.

4. Insert the front round standoff into the front chassis rail locating hole.

5. Support the chassis rail assembly against the front vertical cabinet rail

and maintain the front round standoff in its locating hole. Extend the rail

bracket to insert the rear round standoff into its correct rear chassis rail

locating hole.

6. Fasten the chassis rail assembly to the inner ﬂanges of the front and

rear vertical cabinet rails with four shoulder screws with lockwashers, as

shown.

7. Fasten the rail bracket to the rear vertical cabinet rail with one sems

screw, as shown.
