Installing NEBS 2000 frame-to-EIA adapter brackets
Install NEBS 2000 frame-to-EIA adaptor brackets to the uprights of a NEBS
2000 frame to allow 19-inch wide equipment to be mounted in the 21-inch
wide NEBS 2000 frame.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a hardware kit with PEC NTHW14.
• The NEBS-to-EIA adapter brackets are required to mount 19-inch wide
equipment onto the 21-inch wide NEBS 2000 frame.
Procedure steps
1 While facing the front of the switch, unfasten the pairs of thread-forming
10-mm (3/8-in.) hex-head screws of the top 3 brackets on each side of the
frame. Put the screws and brackets aside to be re-installed later.
2 On the front of the NEBS 2000 frame, locate the first screw hole or dimple
below the mounting ear of the breaker interface panel.
3 Locate any cable management brackets at the rear of the frame. Record
the location and whether the arms point forwards or rearwards of any
bracket in the top half of the frame.
4 Unfasten the 10-mm (3/8-in.) screws of the cable brackets on the back of
the frame. Put the screws and brackets aside to be re-installed later.
5 Remove the left and the right adapter brackets (part number P0905867)
from the hardware kit NTHW14.
6 Hold the left bracket so that
a. it is vertical and two columns of holes face you
b. the label TOP faces you and is at the top
c. the wider spaced holes are at the left side
7 The column of wider spaced holes are intended to fasten to the frame
upright. Align the top hole of the bracket with the dimple immediately
below the BIP.
8 Fasten a 10-mm (3/8-in.) screw through the bracket into the marked hole
in the upright. The top holes of the bracket align with the first hole or
dimple below the BIP’s mounting ear.
