Removing a shelf filler panel
Remove a shelf filler panel from the front and/or rear of a NEBS 2000 frame
to enable installing other equipment onto or between the frame uprights. With
a door installed, you no longer need the panel to prevent access to the inside
of the frame.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a helper to support:
— the weight of the panel when it is unfastened because it weighs about
6.8 kg (15 lbs) and can be awkward by its size
— any other equipment that shares the same mounting screws, for
example, an NTQS31 sparing panel or NTHW52 fanout panel
• When removing a filler panel that shares mounting screws with other
equipment (other than cable management brackets), you may have to
remove its opposite filler panel to enable easier access to the other
equipment. Other equipment includes sparing panels or fanout panels
(termination panels).
Procedure steps
1 Behind the filler panel, determine whether any termination panel shares
screws with the filler panel. If so, you must decide how to remove the
termination panel before removing the filler panel. If the opposite side of
the frame also has a filler panel, you must decide whether removing the
opposite panel enables easier access with less risk of dropping the
shared equipment.
2 If decided, remove the opposite filler panel. Have a helper hold the panel
while unfastening the 2 remaining 10-mm (3/8-inch) screws. Put the panel
and screws aside temporarily.
3 If the filler panel shares screws with a termination panel, unfasten the
bottom 10-mm (3/8-inch) shared screws. Have a helper hold the
termination panel from the other side of the frame while you unfasten the
last 2 screws. Put the termination panel and screws aside temporarily.
4 Repeat step 3 for each other termination panel or other equipment except
cable management brackets.
