Procedure steps
1 Unpack the sparing panel from its container.
2 At the front or rear of the NEBS 2000 frame, determine where on the 2
NTHW14 adapter brackets that the top mounting holes of the panel are to
be. Count holes from the top or bottom (whichever is shorter) on both
brackets to ensure a level installation. Mark the holes.
3 Hold the panel in one hand so that:
• the faceplate lettering reads right to left and top to bottom
• the connections face into or out of the frame as desired
4 Position the sparing panel against the brackets and align the mounting
holes.
5 Thread an EIA thread-forming screw through the upper left and the upper
right mounting ear holes of the sparing panel. Leave the fastener almost
seated. Use the fasteners that were included with the panel because the
10-mm (3/8-in.) frame fasteners are too wide for thread-forming into the
adapter brackets.
When turning a thread-forming screw into a hole for the first time, ensure
that the screw is perpendicular to the hole.
On any other mounting apparatus, use whatever screws were provided
and follow whatever instructions are provided with it.
6 Align the remaining mounting holes on the panel with the holes on the
brackets and loosely tighten the remaining 2 screws.
7 Tighten all screws to snug plus a 1/4 turn. If you strip a hole or a fastener,
you must move the sparing panel so that it has 4 firm fastenings.
