Installing extended cable management brackets
Install extended cable management brackets on a NEBS 2000 frame to
accommodate high-density cabling for electrical FPs. The extended cable
management brackets can only be used with coax cables.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need four extended cable management brackets per side of a frame
with these part numbers:
— NTHRU0368 for the left side facing the front of the frame
— NTHRU0369 for the right side facing the front of the frame
• Each kit contains all of the hardware to mount one bracket. You will need
up to four for each side of the frame, depending on how you are handling
the cable management. For example, if FP cables are routed overhead of
the frame from the upper cage of the lower shelf, you need three brackets.
• The NEBS 2000 frame arrives with standard cable management brackets
already screwed to the uprights at the front and rear sides of the frame.
When a cage is provisioned with a specific type and quantity of FPs, the
standard cable management brackets must be replaced by the optional
extended brackets in kits. Refer to the criteria for using extended cable
management brackets in assessing cable management in 241-1501-200

• To accommodate fiber optical FP cables, use the procedure “Installing
high-density cable management brackets” (page 619).
Procedure steps
1 Open the kit NTHRU0369 and remove all packaging.
2 Cut the tie-wraps off the cables on the pre-installed cable management
brackets on the front right upright of the frame. Be careful not to cut any
of the cables.
3 Unfasten the 6-mm (15/64-in.) hex-head screws of each cable bracket up
the front and put the brackets aside. Also put the screws and washers
aside for re-use. Leave the cables connected and hanging loosely.
