Planning for Remote Dial-In and Dial-Out Support

If you plan to configure a system for both dial-in and dial-out remote support, HP

recommends that you configure two system consoles and two modems. One system

console and modem is used for dial-in access to the system, and the other system

console and modem is used for dial-out access from the system. Dial-ins and dial-outs

are possible using only one system console and one modem on a system, but this

configuration lacks fault-tolerance.

Dial-Outs

Two system consoles can be designated as primary and backup dial-out points for

each system. These consoles, also called primary and backup system consoles, must

be connected to a dedicated LAN (one used for OSM or TSM only). If your system has

only one system console (the primary system console), this workstation is defined as

the primary dial-out point. If the dedicated LAN contains multiple servers, HP

recommends that the primary and backup system consoles each be configured to

receive incident reports from no more than 10 servers on the LAN.

Dial-Ins

All system consoles provided by HP include remote operations software for dial-in

capability, and any system console connected to a modem can receive a dial-in. The

workstation must reside on the same subnet as the primary system console. For more

information about dial-in and dial-out, refer to the OSM or TSM Notification Director

online help.

Note. Remote access and remote notification are not available in countries where the modem

provided by HP is not certified. In these countries, you cannot use the OSM or TSM client

software to dial out to or accept dial-in communications from a service provider.

Caution. Removal of hardware that has not failed will register as a failure and will cause a

dial-out to the GCSC call center.
