5 Plug the power cord (supplied) into the power socket
located on the switch’s rear panel; next, plug the cord into
an easily-accessible grounded AC power source. See
“Electrical Requirements” on page 6 for more informa-
tion.
Note. Do not turn on the power supplies at this time. You
will power on all switches later in the setup process.

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 provides two rack-mount flanges with each
OmniSwitch 6600 Family 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 offers optional 23-inch rack-mounting hard-
ware. For more information, contact your Alcatel repre-
sentative.
• Alcatel 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 per the rack manufac-
turer’s specifications.
• Review page 9 for important chassis airflow and access
recommendations before installing.
To rack-mount the switch, follow the steps below.
1 Align 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.
