NOTE: If you need to mount the switch in a recessed posion on either a two-post rack or a
four-post rack, you can use the 2-in.-recess front-mounng brackets provided in the separately
orderable four-post rack-mount kit.
NOTE: To ensure that the protecve earthing terminal is accessible through the opening in the
rear mounng-blade:
• Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounng
the switch ush 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 li the switch while another secures it to the rack.
CAUTION: If you are mounng mulple units on a rack, mount the heaviest unit at the
boom of the rack and mount the other units from the boom 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 at, stable surface.
NOTE: The four-post rack-mount kit ships with the short front-mounng brackets aached to
the side mounng-rails. If you want to recess the switch in the rack, you must unscrew the
short front-mounng brackets from the side mounng-rails by using the
Phillips (+) screwdriver and aach the long front-mounng brackets to the side mounng-
rails.
2. Align the side mounng-rails along the side panels of the switch chassis. Align the two holes in the
rear of the side mounng-rails with the two holes on the rear of the side panels.
