Installing cable management brackets
Install cable management brackets onto the adapter brackets of a 23-inch
wide rack to enable cable management.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• The cable management brackets to mount a shelf onto a 23-inch wide
rack are included in switch hardware packages NTQS04 for a
Passport 15000 or NTQH04 for a Passport 20000. To install cable
management brackets, you need these parts:
— 2 metal cable management brackets (part number P0879577)
— 28 plastic brackets (part number P0937935)
Procedure steps
1 While facing the rear of the rack, locate the left and right short adapter
brackets that have the strain-relief bar and the temperature sensors
fastened to them. These are the only short brackets that will not have
cable management brackets fastened to them.
2 Loosely fasten a cable management bracket to each remaining short
adapter bracket on the rear uprights. Use the thread-forming 10-mm
(3/8-in.) hex-head screws from pack P0601478 through each mounting-
ear hole. Notice the orientation of the cable management brackets in the
figure “Mounted cable management brackets onto rear adapter brackets”
(page 598). The top 8 cable management brackets (4 per side) are metal,
while the bottom 2 or 4 (1 or 2 per side) are plastic.
3 Tighten all rear cable management bracket screws to snug plus a 1/4 turn.
4 While facing the front of the rack, loosely fasten a plastic cable
management bracket in the positions shown by the figure “Mounted cable
management brackets onto rear adapter brackets” (page 598).
5 Tighten all front cable management bracket screws to snug plus a 1/4
turn.
