organized methods of cabling. For example, before marking the footprint of
the frame onto the floor in preparation for anchoring it, you must consider
where optional equipment is located for cabling the system.
The hardware and method involved in managing telecom cables includes:
• "Basic cable management brackets for low-density cabling" (page 316)
• "Cable management brackets for high-density cabling" (page 319)
• "Hardware to manage fiber cable slack near the switch" (page 326)
• "Cabling a card with or without a termination panel" (page 330)
When a Passport 15000 or 20000 switch is mounted in a NEBS 2000 frame,
the basic cable management brackets are already installed on the frame. If a
shelf-based switch is shipped for installation into a mounting apparatus other
than the NEBS 2000 frame, basic cable management brackets are shipped
without being installed.
A basic cable management bracket is a plastic one with three segregated
sections. All switch hardware packages have 28 plastic cable management
brackets and two metal brackets at the upper rear of each NEBS 2000 frame.
The metal brackets (P0879577) have two fingers each and are intended for the
heavier and thicker electrical cables being routed up to a cable trough. (When
power cables are routed down through the floor, they are to be fastened to the
zig-zag bars of the frame, not the basic or optional cable management
brackets.) See the figures
• "Metal and plastic cable management brackets on a NEBS 2000 frame"
(page 317)
• "A plastic cable management bracket P0937935" (page 318)
With any switch hardware package, enough cable management brackets are
provided to ensure tight and neat cable dressing for low-density cabling of
fiber and mini-coax cables. For switch configurations that have higher density
cabling, optional hardware is available. See "High-density cable management
brackets" (page 320).
