• the 3-prong wire connectors point to the right side
• the mounting ears are above the flat span of the bracket
3 Locate the nearest mounting holes on the uprights of the NEBS 2000
frame as shown in the figure “Location of the temperature sensor bracket
assembly on a NEBS 2000 frame or a rack” (page 540) or on the adapter
brackets that are already fastened to a 23-in. wide EIA rack as shown in
the figure “Location of the temperature sensor bracket assembly on a
23-inch wide EIA rack” (page 541).
4 Insert the bracket assembly between the frame uprights or the rack
adapter brackets, below the BIP, and above the shelf until the mounting
ears touch the uprights or the adapter brackets.
5 Align the mounting-ear screw holes (shown in the figures) with the lowest
holes on the brackets.
6 Loosely fasten a threading-forming 10-mm (3/8-in.) hex-head screw from
pack P0601478 through the 2 mounting-ear holes.
7 Center the sensor bracket and tighten both screws to snug plus a 1/4 turn.
8 At the end of the cable assembly with the 3 connectors occurring at
different lengths, connect the longest one to the left sensor, the middle
one to the middle sensor, and the shortest the right. Ensure that you plug
in each connector, with gentle, even, steady, straight force.
9 Route the rest of the cable assembly to the right side of the rack and down
to the rear of the cooling unit. Leave it hanging loosely for now.
