• To determine the operational status of a port that has an SFP plugged into
it, especially if a LED is unlit, use the procedure 241-5701-600 Passport
7400, 15000, 20000 Configuration Guide to display the status of an
installed SFP optical module.
• When a port pair on dual-FPs is to be configured for Y-protection, ensure
that the software configuration is completed before connecting the
Y-splitter cables.
• When connecting cables in a spared configuration, complete the main
connections first, and then the spare connections. Many sparing panels
automatically start operating through the main connections.
• For coax cables between an FP and a sparing panel or a fanout panel,
connect the transmit (Tx) at the FP to the Tx at the panel, and the receive
(Rx) to Rx.
• For more information about cable management refer to 241-1501-200

Procedure steps
1 Match the label on the connector or connectors of the fiber cable to the
port on the faceplate of the FP.
For an initial switch installation, always start cabling from the rightmost FP
and move left. The intent is to have the FP cable cluster that is nearest the
brackets stay closest to the FP on the brackets so that crossing cable
clusters is minimized.
For each FP, always start at the bottom right port and move upwards. If
the FP has two columns of ports, continue down to the bottom left. This
facilitates efficient cable management especially when port densities are
high (for example, with 16-port OC-3/STM-1 FPs).
2 On the fiber cable, ensure that its label will reside outside the faceplate
hood when it is closed, especially for the 16-port OC-3/STM-1 FPs.
3 Remove the dust plug or boot from the transceiver or connector on the
port connection of the FP. Put them aside for re-use in another procedure.
4 Remove the dust boot or cover from the end of the cable connector. If the
connector is duplex, also remove the boot from its mate. Put the boots
aside for re-use in another procedure.
5 Connect the cable as indicated in the figure “Types of connectors on
Passport FP cables” (page 323) and in the table “Actions to engage types
of FP connectors” (page 324).
