Installing a shelf filler panel
Install a shelf filler panel to cover an opening in the upper half of the front or
rear of a NEBS 2000 frame.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need one or both of these parts:
— front filler panel with PEC NTHR76 (1 m or 3.3 ft)
— rear filler panel with PEC NTHR77 (800 mm or 2.6 ft)
• When a sparing panel or fanout panel is to be or is already mounted onto
the upper half of a NEBS 2000 frame, the termination panel must be
mounted between the frame and the filler panel. The termination panel
and the filler panel can share the same mounting screws, but you will
need at least one helper to hold the parts until they are fastened.
• You may need a helper to hold a panel until the first 2 mounting screws
are fastened.
Procedure steps
1 Open the kit and unpack the filler panel and thread-forming screws.
2 Count 4 dimples or holes or both in the grounding strip on the outside face
of the right front frame upright starting below the top cable management
bracket. The dimples cover holes in the uprights. Count downwards and
mark the hole (or poke through the dimple). Mark its mate on the opposite
upright.
3 Hold the panel against the front (or rear) face of the frame uprights as in
the figure“Location of the front shelf filler panel” (page 511) so that
• the edge labeled TOP is pointing upwards
• the hollow space between the sides faces inwards to the front of the
frame
• the top two holes in the sides of the panel align with the 2 holes
marked on the frame uprights
• the cut-ins at the sides of the panel surround the cable management
brackets, that is, the panel does not overlap any bracket
