Cabling Common Equipment in a Multi Group system
which faces the front of the module, contains the primary shrouds, which
provide mechanical guidance for the pins of the card edge connectors. The
secondary side of the backplane, which faces the rear of the module, contains
the secondary shrouds, which provide mechanical guidance for cable
connectors.
When routing cCNI to 3PE cables, store any excess cable length near the
associated Network module. Do not store excess cable in the Core/Net
module.
Because the cable troughs and spaces on the sides of a module are within the
EMI shielding of the system, unshielded cables can be routed in those areas.
As space permits, Common Equipment cables can be routed horizontally in
the cable troughs at the front, rear, and sides of the module or vertically on
the sides of the module.
Note: In a DC-powered module, because there is no MPDU, there is
room to route cables horizontally from front to rear on the left side (front
view) of the module.
CAUTION — Service Interruption
System Failure
Cables must be routed as perpendicular as possible
to any nearby power cables. Avoid routing cables
near power cables if alternate routing is available.
At the rear of the module, cables routed between the
I/O panel and the rear cover can be parallel to the
power cables because the panel provides EMI
shielding.
