NOTE: If you need to mount the switch in a recessed position on either a two-post rack or a
four-post rack, you can use the 2-in.-recess front-mounting brackets provided in the separately
orderable four-post rack-mount kit.
NOTE: To ensure that the protective earthing terminal is accessible through the opening in the
rear mounting-blade:
• Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounting
the switch flush with the rack front on four posts of a rack.
• Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if you will mount the
switch 2 in. recessed from the rack front.
NOTE: One person must be available to lift the switch while another secures it to the rack.
CAUTION: If you are mounting multiple units on a rack, mount the heaviest unit at the
bottom of the rack and mount the other units from the bottom of the rack to the top in
decreasing order of the weight of the units.
To mount the switch on four posts of a rack:
1. Place the switch on a flat, stable surface.
NOTE: The four-post rack-mount kit ships with the short front-mounting brackets attached to
the side mounting-rails. If you want to recess the switch in the rack, you must unscrew the
short front-mounting brackets from the side mounting-rails by using the
Phillips (+) screwdriver and attach the long front-mounting brackets to the side mounting-
rails.
2. Align the side mounting-rails along the side panels of the switch chassis. Align the two holes in the
rear of the side mounting-rails with the two holes on the rear of the side panels.
