Rack Installation
To install the Model 281xSA hub in an equipment rack, follow these steps:
1.
Attach the mounting brackets.
a. On each side of the hub, use a #1 Phillips screwdriver to remove the
screws at the front corner (see Figure 2-5).
Figure 2-5. Attaching brackets for rack installation
b. Hold a mounting bracket against each side of the hub, as shown in
Figure 2-5, and align the countersunk screw holes in the bracket with
the bracket mounting holes in the hub.
The bracket covers a few of the chassis ventilation holes. This does not
compromise the cooling of the hub.
c. Insert two #4-40 x 5/16 flat-head screws through each bracket and into
the bracket mounting holes in the hub cabinet.
d. Using a #1 Phillips screwdriver, tighten the screws to secure each
bracket.
