Installing the Dial Shelf in the Rack
One person can not install the dial shelf chassis in the rack unassisted. T wo or preferably three peopl e
will be needed.
To secure the rack-mount brackets to the posts or mounting strips in the rack, you must use the
slotted mounting screws provided. Because the brackets support the entire weight o f the chassis, be
sure to use at least two slotted screws per bracket.
Be sure you have the dial shelf prepped as described in the previous chapter before installing it in
the rack. To install the d ial shelf chassis in t he rack, complete t he following steps:
Tips To prevent injury, review the safety precautions in the “Safety Recommendations” section on

Step2 Attach one support bracket to each front post or mounting strip using the pro vided slot ted
screws and a 1/4-in., flat-blade screwdriver. Ensure that the support brackets are level.
(See Figure3-5 and Figure 3-7.)

two slotted screws per b racket. These brackets a lso ensure that the re quired space between
the dial shelf and the power supply is available.
