Attaching the Slide Brackets
Secure two slide brackets to each switch.
CAUTION: Ensure that the mounting screws are the proper length
and that flat washers are used. Installing screws longer than 9/32
inch or without a flat washer may damage the switch.
• For older 8-port switches (380591–B21/ DS–DSGGA–AA)
in rack-front and rear installations, see Figure 8.
Use four pan head SEMS screws (10-32 x 9/32 inches) and
four flat washers to attach the mounting brackets to the
switch.
IMPORTANT: Attach the slide brackets using a flat washer with each
screw. Without the flat washers, the screws contact with the power
supply assembly inside the switch chassis.
