Labeling a card cable connection
Label each CP and FP cable connection to ensure that it can be reconnected
to the appropriate connector at each junction of the connection path.
Prerequisites
• Whether you plan to route one cable at a time from end to end of the full
connection path between the FP and its far end, or route a cluster of
cables along the path, you must ensure that each physical connection of
the cable matches the software configuration. The software depends on
matching the port number and slot number of a card in order to run
without generating alarms for misconnected ports. You can connect and
label the cables and then configure the software to match, or you can
ensure that each cable connects to the appropriate port or ports along the
connection path. Either way, each physical port connection must match
its software configuration.
• You must determine the full path of each interface port along the
connection path. Each cable connection to a hardware unit that is part of
the connection path must have unique connection identification
information. The connection path can include a combination of the
following equipment:
— the near-end FP faceplate
— a termination panel such as a fanout panel, a sparing panel, or a fiber
optic patch panel
— an interworking device such as a DS1 EdgeLink 100 mux or a
multiport aggregate device
— the far-end termination such as another FP, a Nortel Networks
product other than a Multiservice Switch, or a non-Nortel Networks
product (also referred to as customer premises equipment or CPE)
• Typical identification information for each Multiservice Switch card
cable connection includes:
— the port number or series of port numbers on the card’s faceplate
— the direction of the port as transmit (Tx) or receive (Rx)
— the connection identifier that is on the hardware unit to which the
cable will be connected
