Rack-Mounting the OS6800-BPS-SHLF Power Shelf
Refer to the important guidelines below before installing the OS6800-BPS-SHLF power shelf in a rack.
• The power shelf can be installed with either the power supply bays or the fan vents facing out. Screw
holes for rack-mount flanges are provided on either side of the power shelf. As a result, either panel
can be considered the front panel, depending on the preferred installation. Note that installations in
which the power supplies face out require a longer connector cable distance between the switch chas-
sis and the power shelf. Before attempting to install the power shelf in a rack, be sure that the connec-
tor cables have adequate reach.
• It is recommended that two people install the power shelf in the rack—one person to hold the shelf and
position it in the rack, and a second person to secure the shelf to the rack using attachment screws (not
supplied).
• Alcatel-Lucent provides two rack-mount flanges with each OS6800-BPS-SHLF power shelf. These
flanges support standard 19-inch rack mount installations. These flanges must be attached to the chas-
sis before the power shelf can be rack mounted.
Note. If you are installing the power shelf in a 23-inch wide rack, Alcatel-Lucent offers optional 23-inch
rack-mounting 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 power shelf in a relay rack, be sure to install and secure the rack per the rack
manufacturer’s specifications.
• Review page 2-16 for important chassis airflow and access recommendations before installing.
Rack Mounting Steps
To rack-mount the power shelf, follow the steps below:
1 Align the holes in the provided rack-mount flanges with the four threaded holes in the power shelf.
These threaded holes are located in the left and right sides of the power shelf, near the front panel.
2 Attach the flanges to the power shelf using the provided Phillips-head screws. Be sure to tighten each
of the screws firmly using a Phillips screwdriver.
Attaching a Rack-Mount Flange
Note: The power shelf can be installed with either
the power supply bays or the fan vents facing out.
Screw holes for rack-mount flanges are provided
on either side. This example diagram shows the
an installation in which the power supply bays are
facing out. Refer to the list of guidelines above
for more information.
