Installing front or rear frame panels
Install the front or rear panels on a NEBS 2000 frame to protect and hide the
cable installations up and down the sides.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need kit numbers NTRU0185 and NTRU0366. Kit NTRU0185
includes the panel that spans across the top edge of the NEBS 2000
frame, and has threaded screw holes at each end to fasten the panel of kit
NTRU0366. Kit NTRU0366 contains a vertical panel that can be
installed in a front or rear location at the left or right side of the frame.
The panel brackets differ for front and rear fastenings, but the procedure
to mount either is the same. Kit NTHW51 is the same as NTRU0185
except it includes an equipment label. A panel with the label is intended
for the top front of a NEBS 2000 frame.

Procedure steps
1 Separate the contents of the kits.
2 See the figures “Location of front and rear panels, exploded view”
(page 614) and “Installed front, rear, and side panels” (page 617).
Observe the position of the upper and lower pairs of brackets. The upper
brackets differ in shape from the lower brackets. The upper brackets
fasten to the top cover assembly from kit NTRU0185.
3 From the kit NTRU0185, place the top bracket in position according to the
figure “Location of front and rear panels, exploded view” (page 614).
4 Fasten the top bracket using the provided thread-forming 6-mm
(15/64-in.) hex-head screws. Tighten the screws to snug plus a 1/5 turn.
5 Fasten the top cover to the top bracket to complete the top cover
assembly.
6 From the kit NTRU0366, align an upper bracket (P0902814) according to
the figure “Upper brackets for frame panels” (page 615).
7 Fasten the bracket to the cover using the 2 provided thread-forming 6-mm
hex-head screws.
8 Repeat step 6 and step 7 for the other 3 upper brackets.
