Connection problems using a modem in shared mode

If you are unable to login to the IRC in shared mode, it is strongly recommended that you first troubleshoot the problem with modem sharing options set to dedicated. Once proper operation has been verified, return to shared mode and proceed in this section if the problem still exists.

If you are able to login to IRC, but are either unable or not consistently able to connect through Integrated Remote Console to operating system-based management, it is strongly recommended that you troubleshoot the problem by temporarily disabling IRC. Once proper operation of the modem has been verified in the operating system with Integrated Remote Console disabled, re- enable Integrated Remote Console and proceed in this section if the problem still exists.

This section assumes that there are no connection problems with IRC when the modem is configured as dedicated, and there are no connection problems to operating system-based management when Integrated Remote Console is disabled.

Managed Server does not answer the phone in shared mode

The management console attempts to establish a connection with IRC, but the phone is not answered.

Explanation: Operating system has taken ownership of the modem and disabled auto-answer mode.

Solution: Check the following:

■Make sure that the operating system is not currently using the modem for another connection.

■The operating system may have recently accessed the modem. IRC will regain ownership of the modem if no activity is detected for 60 seconds. Wait 60 seconds and try again.
