Rack-Mounting the Power Shelf
Refer to the important guidelines below before installing the power shelf in a rack.
•
If the power shelf was not shipped with power supplies installed, it is recommended that you install the
power supplies
after you have rack mounted the switch
. This will minimize the weight of the chassis
when positioning and installing the power shelf. For detailed information on installing power supplies,
refer to
•
It is recommended that two people install the power shelf in the rack—one person to hold the unit and
position it in the rack, and a second person to secure the unit to the rack using the rack attachment
screws (not provided).
•
Alcatel provides two rack-mount flanges with each power shelf. These flanges support standard
19-inch rack mount installations. These flanges must be attached to the power shelf before the power
shelf can be rack mounted.
Note.
If you are installing the power shelf in a 23-inch wide rack, Alcatel offers optional 23-inch rack-
mounting hardware. For more information, contact your Alcatel representative.
•
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 power shelf in a relay rack, be sure to install and secure the rack per the rack
manufacturer’s specifications.
To rack-mount the power shelf, follow the steps below.
1
Align the holes in the provided rack-mount flanges with the threaded holes located in the left and right
sides of the unit.
