You can mount the switch on two posts in either a two-post rack or a four-post rack by
using the mounting brackets provided with the switch. See
on Two Posts in a Rack or Cabinet” on page 114
NOTE:
If you are mounting the switch on four posts, ensure that the rack is
21.5 in. through 31.5 in. deep if you will mount the switch flush with the rack
front and that the rack is 23.5 in. through 32.5 in. deep if you will mount the
switch 2 in. recessed from the rack front, thus ensuring that the protective
earthing terminal is accessible through the opening in the rear
mounting-blade.
Before mounting the switch on four posts in a rack:
•
Verify that the site meets the requirements described in
for EX4500 Switches” on page 77
•
Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
•
Read
“General Safety Guidelines and Warnings” on page 221
, with particular attention
to
“Chassis Lifting Guidelines for EX4500 Switches” on page 235
•
Remove the switch from the shipping carton (see
“Unpacking an EX4500 Switch” on
).
•
Have two persons available to mount the switch. One person will support the switch
in a level position, and the second person will secure the switch to the rack.
Ensure that you have the following parts and tools available:
•
Phillips (+) screwdriver, number 2
•
12 flat-head M4x6-mm Phillips mounting screws (provided with the four-post
rack-mount kit)
•
One pair of front-mounting brackets
•
One pair of rear mounting-blades
•
Screws to secure the front-mounting brackets and the rear mounting-blades to the
rack (not provided)
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.
