Cabling Common Equipment in a Single Group system
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.
