Cisco Systems IGX 8400 Series manual Connecting a Modem, Connecting Modems to an IGX Node

Attaching Peripherals

Step 4 Tighten the EIA/TIA-232/V.24 connector screws to firmly attach the cable connector to the AUX port connector.

Step 5 Plug the printer power cord into the appropriate wall receptacle.

Connecting a Modem

Two modems can be connected to the IGX node to provide access for remote troubleshooting and for remote alarm logging. (See Figure 3-21.) Each connection between the SCM and a modem requires a special cable and setup procedure.

The modem that provides access for remote troubleshooting from the Cisco TAC office (TAC-to-IGX modem) connects to the Control Terminal port on the SCM. Typically, the modem connects to the telephone wall jack with a direct-dial line. You can reach the TAC through Cisco Customer Engineering.

The modem that is used to provide remote alarm logging (IGX-to-TAC modem) is connected to the AUX port on the SCM. This modem connects to a wall jack using a standard telephone line.
