Installing the Switch in a Telco Rack
To install the switch in a Telco rack:
1. Install each of the 8 clip nuts provided onto each side of the front of the rack (4 clip nuts per rack
mount flange). Install each clip nut behind a hole into which you plan to install a trusshead screw.
(See Figure 5 on page 13.)
2. Slide the switch into the rack until both rack mount flanges are flush with the front of the rack.
CAUTION:
Continue to support the weight of the switch until after you have installed four of the eight
screws (2 screws per rack-mount flange).
If you attempt to place the weight of the rack-mounted 8265 switch on fewer than four fully
installed screws, the switch may drop off of the rack. Personal injury or serious damage to the
switch may result.
3. Match the uppermost open slot on each rack mount flange with the corresponding hole on the rack.
Hold the switch in place until you complete step 4. The remaining three open slots on each rack
mount flange automatically line up when each uppermost open slot is matched to a hole on the rack.
4. Secure the switch to the rack with the screws provided (eight, 10-32 x 1/2-inch screws):
a. Install one screw in the uppermost open slot on
each of the rack mount flanges.
b. Install an additional screw in each rack mount flange, and tighten all screws completely before you
allow the weight of the switch to rest (unaided) on the rack. A fully installed screw is flush with the
surface of each rack mount flange.
c. Install the remaining screws in open slots on each rack mount flange (for a total of four screws per
rack mount flange). Install each screw so it is (approximately) equidistant from the screw installed
directly above it and the screw installed directly below it. Tighten the screws completely.
