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
CAUTION
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.
