3.16 Chassis Rail Installation (Universal Rails)
1. Turn the cabinet power off.
2. Determine the correct enclosure mounting locations and corresponding
cabinet rail mounting holes for the chassis rail assembly. Refer to the
chapter in this document pertaining to your specific cabinet configuration
for this information. The enclosure mounting hole specified for each
position is the chassis rail locating hole shown in Figure 3–8.
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 front 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 front of the cabinet, and that the arrow on the rail
bracket points up.
4. Insert the rear round standoff into the rear chassis rail locating hole.
5. Support the chassis rail against the rear vertical cabinet rail and maintain
the rear round standoff in its locating hole. Extend the rail bracket to
insert the front round standoff into its correct front chassis rail locating
hole.
