Rcm Overview - Compaq AlphaServer 1200 User Manual

6.1 RCM Overview

The remote console manager (RCM) monitors and controls the system remotely.
The control logic resides on the system board.
The RCM is a separate console from the SRM and AlphaBIOS consoles. The RCM
is run from a serial console terminal or terminal emulator. A command interface lets
you to reset, halt, and power the system on or off, regardless of the state of the
operating system or hardware. You can also use RCM to monitor system power and
temperature.
You can invoke the RCM either remotely or through the local serial console
terminal. Once in RCM command mode, you can enter commands to control and
monitor the system. Only one RCM session can be active at a time.
•
To connect to the RCM remotely, you dial in through a modem, enter a
password, and then type an escape sequence that invokes RCM command mode.
You must set up the modem before you can dial in remotely.
•
To connect to the RCM locally, you type the escape sequence at the SRM
console prompt on the local serial console terminal.
When you are not monitoring the system remotely, you can use the RCM dial-out
alert feature. With dial-out alerts enabled, the RCM dials a paging service to alert
you about a power failure within the system.
CAUTION: Do not issue RCM commands until the system has powered up. If you
enter certain RCM commands during power-up or reset, the system may hang. In
that case you would have to disconnect the power cord at the power outlet. You can,
however, use the RCM halt command during power-up to force a halt assertion.
Refer to Section 3.12 for information on halt assertion.
