Cabling Common Equipment - Nortel Meridian 1 Manual

Cabling common equipment

Note: This procedure does not apply to the option 51C system.
Use the following guidelines for routing common equipment cables for
options 61C, 81, and 81C:
— When routing CNI to 3PE cables, store any excess cable length near the
associated Network Module. Do not store excess cable in the Core/Net
Module.
— When routing DIGS to intergroup cables, store excess length near the
InterGroup 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
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.
— vertically on the sides of the module
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.)
