the secondary shrouds, which provide mechanical guidance for cable connectors.

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

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.

A label kit is included in system package. Use of these labels is optional.

Note: To replace cables from the Core/Net module backplane, you must use the P0741489 Extraction Tool provided, located in the rear of the module (behind the I/O safety panel).

CAUTION — Damage to Equipment

Do not pry the against the connector with the extraction tool. Simply inserting the tool between the connector and the securing clip is sufficient to unlock the connector. Prying may cause damage to the connector or the backplane pins.
