7. Have a second person secure the switch to the rack by using the appropriate screws.
Tighten the screws using the appropriate screwdrivers.
8. Ensure that the switch chassis is level by verifying that all screws on one side of the
rack are aligned with the screws on the other side.
NOTE: We recommend that you install cover panels in unused module slots
and dust covers in unused SFP/SFP+ ports.

Mounting an EX4550 Switch on Four Posts in a Rack or Cabinet
You can mount an EX4550 switch on four posts in a 19-in. rack or cabinet by using the
separately orderable four-post rack-mount kit. (The remainder of this topic uses rack to
mean rack or cabinet.)
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 “Mounting an EX4550 Switch
on Two Posts in a Rack or Cabinet” on page 148.
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 mount
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.
