Rear Support Bars and Brackets
Under normal conditions, mounting the frame to the front of the rack with four rack screws should be
sufficient to carry the load, including the weight of accompanying cables. The optional FSB-8321 Rear
Support Bars and Brackets are specifically engineered to compensate for extra load stress associated
with certain applications, such as mobile truck installations, to also support the rear of the frame.
Figure 15. FSB-8320 Rear Support Bars and Brackets Diagram
Installing the Rear Support Bars and Brackets
Use the following procedure to install the FSB-8321 rear support bars and brackets:
1. The rear support bars can be attached to the frame in six possible positions; refer to
Figure 15. Choose the position that suits the cabinet depth that will give
approximately a ½ inch (0.5") projection beyond the rear vertical mounting rails.
Using four screws per bar, as shown in the illustration, fasten one bar to each side of
the frame.
2. Mount the frame to the front rails of the rack cabinet using four rack screws fastened
through the front mounting flanges.
3. At the rear of the cabinet, slide the bracket slots over the rear of the support bars and
secure to the cabinet rear rails with two rack screws each.
This completes the procedure to install the FSB-8320 rear support bars and brackets.
