Replacing PA-4T+ Port Adapter Cables

Caution Serial interface cables must be attached correctly or damage to the cable plug will result. Attempting to force a cable plug on the 60-pin receptacle can damage the plug. (See Figure 7-2.)

Step 2 Attach the network end of the serial cable to your DSU, CSU, DTE, or other external synchronous serial equipment and tighten the strain-relief screws.

This completes the procedure for attaching serial interface cables to the PA-4T+.

Replacing PA-4T+ Port Adapter Cables

The port adapter cable connected to each port determines the electrical interface type and mode of the port. The default mode of the ports is DCE, which allows you to perform a loopback test on any port without having to attach a port adapter cable. Although DCE is the default, there is no default clock rate set on the interfaces. When there is no cable attached to a port, the software actually identiﬁes the port as Universal (cable unattached) rather than either a DTE or DCE interface.

Following is an example of the show controllers command for Cisco 7100 series, Cisco 7200 series or Cisco uBR7200 series routers that shows an interface port (1/0) that has an EIA/TIA-232 DCE cable attached:

Router# show controllers serial 1/0

M4T: show controller:

PAS unit 8, subunit 0, f/w version 1-25, rev ID 0x2800001, version 2 idb = 0x60B83B40, ds = 0x60B858B8, ssb=0x60B85FFC

DCD=up DSR=up DTR=up RTS=up CTS=up line state: up

cable type : V.24 (RS-232) DCE cable, received clockrate 9600 [display text omitted]

Note In the above output from the show controllers command, the PA-4T+ is displayed as M4T.
