Install mounting ears on the fiber management tray.
NOTE
By default, the fiber management tray is installed in the lower part of the cabinet and is more than 50 mm
away from the subrack. The fiber management tray must also be more than 50 mm away from the air inlet
and outlet of the subrack. The fiber management tray can be installed in a cabinet that is not fully configured
with subracks, but future expansion will be affected due to reduced installation space in the cabinet.
