Prerequisites
If you plan to install a front cover on your HD shelf and you use cables
with MPOconnectors, you must also install the front cover extension. To
determine if your shelf rack or cabinet configuration supports front covers
and extensions, and for more information about accessory installation
requirements, see Accessory Installation Requirements.
When mounting the cover extension to the shelf mounting brackets:
l Verify that you have the specified minimum access clearances for maintenance,
servicing, and other operations. If applicable, verify that the rack cabinet doors can
close.
l If this is not the initial installation of your HD system and the shelf is equipped with
modules, remove the cabling from the power supplies and the adjacent modules on the
left and right side, creating sufficient space for mounting the cover extension.
l Ensure that the cables are correctly labeled so they can be easily reinstalled. Then
remove the relevant modules from the shelf slots, as far as is necessary to install the
cover extension.
EQUIPMENT DAMAGE MAY RESULT IF YOU ARE NOT
CAREFUL WHEN REMOVING AND REINSTALLING
MODULES, AS THIS INCREASES THE CHANCES OF
BREAKING FIBER-OPTIC CABLES OR BENDING PINS ON
THE BACKPLANE.
