Rack mounting
The Model 2750 can be mounted in a standard 19-inch rack. For a mainframe that has one
or no switching modules installed, the Model 2750 can be secured to the front rails of the
rack.
The hardware necessary to secure the mainframe to the front rails of the rack is supplied
with the Model 2750. The supplied hardware kit includes four dress screws and four
retaining clips. Each retaining clip has a captive nut.
Perform the following steps to mount the Model 2750 to front rails of the rack:
WARNING Make sure the Model 2750 is turned off, the line cord is disconnected,
and it is not connected to any external circuitry.
1. Select a location in the rack. The mainframe takes up 3
H
-inches of vertical space.
2. Using Figure 1-3 as a guide, install two retaining clips on the left front rail. Slide
each retaining clip over a mounting hole such that the captive nut is positioned on
the inside of the rack cabinet. In a similar manner, install two retaining clips on the
right front rail.
3. Remove the four foot assemblies from the bottom of the Model 2750. The retaining
screw for an assembly is located under the rubber foot. Simply pull off the rubber
feet to gain access to the screws. Retain these foot assemblies for future use.
4. Position the Model 2750 in the rack and loosely attach the front panel to the rack
rails using the four supplied dress screws.
5. Tighten the four dress screws.
CAUTION For a Model 2750 that has two or more installed switching modules,
rear brackets are required to support the additional weight. The Model
4288-7 is a rack mount kit for the Model 2750 that uses rear support
brackets.
