If the server’s power is interrupted, HP TopTools Remote Control automatically switches to battery operation. HP TopTools Remote Control logs the event and generates an alert (if so configured). In addition, some HP TopTools Remote Control functions that require the server to be powered up are also suspended, including console redirection, PCI Bus Utilization monitoring, and server resets. If a remote connection is active when power is interrupted, the connection will be maintained. The HP TopTools Remote Control card will continue to function for at least one hour on battery power.
NOTE | If you are using an external modem with HP TopTools Remote |
| Control, the modem won’t have access to battery power. To |
| guarantee power to an external modem, use a modem that is |
| attached to an Uninterruptible Power Supply (UPS). |
