Appendix B. Modem Configurations - IBM TotalStorage NAS Gateway 500 Service Manual

Appendix B. Modem configurations

Attention: This appendix applies only to modems attached to serial port S2 located on the CEC
backplane (location U0.1-P1).
The service processor and Electronic Service Agent are designed to place little demand on an attached
modem, thereby increasing the setup and connection success rates.
Modem setup
This section describes how to configure the IBM modems recommended for use with the Electronic
Service Agent and the service processor.
The recommended modems are:
v 7852 Model 400
v 7857-017 or 7858-336
Note: You can use a non-recommended modem. The Electronic Service Agent configuration has an
extensive selection of modems from which you can choose, while the service processor allows you
to customize a configuration modem file if your modem is not listed in its directory. If the Electronic
Service Agent and the service processor are to use the same modem, and you are not using one of
the recommended modems, you must choose a modem from the Electronic Service Agent modem
list. Then you must customize a configuration modem file in service processor that best fits the
modem you are using for the Electronic Service Agent and service processor.
This appendix contains sample modem configuration files that either work directly with your modem or
provide a starting point for a custom setup. The sample modem configuration files are located in your
service processor firmware in the /usr/share/modems subdirectory with the following names. A listing of
each file is included in this appendix.
