Rack-Mounting the Switch
Refer to the important guidelines below before installing the
OmniSwitch chassis in a rack.
•It is recommended that two people install the switch in
the rack—one person to hold the chassis and position it
in the rack, and a second person to secure the chassis to
the rack using attachment screws (not supplied).
•Alcatel-Lucent provides two rack-mount flanges with
each OmniSwitch 6850 Series switch. These flanges
support standard 19-inch rack mount installations.
These flanges must be attached to the chassis before
the switch can be rack mounted.
Note. If you are installing the switch in a 23-inch wide
rack, Alcatel-Lucent offers optional 23-inch rack-mount-
ing hardware. For more information, contact your Alcatel-
Lucent representative.
•Alcatel-Lucent does not provide rack-mount screws.
Use the screws supplied by the rack vendor.
•To prevent a rack from becoming top heavy, it is
recommended that you install heavier equipment at the
bottom of the rack whenever possible.
•If you are installing the switch in a relay rack, be sure
to install and secure the rack as per the rack manufac-
turer’s specifications.
•Review page 6 for important chassis airflow and access
recommendations before installing.
Rack Mounting Steps
To rack-mount the switch, follow the steps below:
Note. Rack-mount flanges may come factory-installed in
some cases. If this is the case, skip steps 1 and 2 below.
1Align the holes in the provided rack-mount flanges
with the four threaded holes in the OmniSwitch chassis.
These threaded holes are located in the left and right sides
of the chassis, near the front panel.
2Attach the flanges to the chassis using the provided
Phillips-head screws. Be sure to tighten each of the screws
firmly using a Phillips screwdriver.
