When adding extended cable management brackets to a
NEBS 2000 frame

When adding a door to a NEBS 2000 frame

The optional extended brackets enable handling the cables of one or two fully
provisioned Passport 15000 or 20000 switches in the frame. Installing the
NTRU0370 junction kits provides brackets and hardware to join two adjacent
and equally enlarged NEBS 2000 frames.
The frame spacer kits in NTRU0365 are used to enlarge the standard 600 by
600 mm footprint of a NEBS 2000 frame. They add 150 mm width to the
footprint, 75 mm on each side. Installing the NTRU0365 kits means that the
spacer brackets from these kits must be installed on each side of the frame.
Installing the spacer brackets enables adding the optional extended cable
management brackets (NTRU0368 and NTRU0369).
The need for the extended cable management brackets is described in
"Managing very high-density coax cabling" (page 43).
The door hardware from kits NTQS37AA and NTQS37AB is added to the
base of a NEBS 2000 frame. When adding a door and its mounting hardware
to a frame, the footprint where the frame is to be anchored or has been
anchored increases into the aisle by 6.6 cm (2 5/8 in.) on that face of the
frame. Adding a door to both the front and rear of the frame increases the
footprint the same on each half for a total of 13.2 cm (5 1/4 in.). The larger
footprint must accommodate:
• space to add the extension hardware and space to install it by hand tools
• space to fully open the door at either the front or rear of frame so that
plug-in cards or modules can be safely removed and installed, as
indicated in "Front and rear access to switch hardware" (page 72)
