Installing a strain-relief bar

Prerequisites
Procedure steps
Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Instal the strain-relief bar to support the weight of the power input cables and
the BIP-to-shelf cable assemblies.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• You need a strain relief bar with the part number P0911981.
1 While facing the rear of the BIP, hold the bar so that:
• the long flat side is at the top
• the short flat side faces you
• the mounting ears point away from you
2 Locate the top rear adapter brackets mounted to the rack.
3 Position the mounting ears of the bar against the top adapter brackets so
that the ear holes align with the remaining 4 adapter holes. The
temperature sensor bracket and the strain-relief bar share the same
adapter brackets. See the figure "Location of the temperature sensor
bracket assembly on a NEBS 2000 frame or a rack" (page 540).
4 While holding the bar in position, loosely fasten a thread-forming 10-mm
(3/8-in.) hex-head screw from pack P0601478 through each upper
mounting-ear hole.
5 Loosely fasten the remaining 2 screws.
6 Center the bar and tighten all 4 screws to snug plus a 1/4 turn.
