Planning for Remote Dial-In and Dial-Out Support
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.
