Operating the System Remotely
This appendix describes how to use the remote console monitor (RCM) to monitor
and control the system remotely.
C.1 RCM Console Overview
The remote console monitor (RCM) is used to monitor and control the system
remotely. The RCM resides on the server control module and allows the system
administrator to connect remotely to a managed system through a modem, using a
serial terminal or terminal emulator.
The RCM has special console firmware that is used to remotely control an
AlphaServer system. The RCM firmware resides on an independent microprocessor.
It is not part of the SRM console that resides in the flash ROM. The RCM firmware
has its own command interface that allows the user to perform the tasks that can
usually be done from the system’s serial console terminal. RCM console commands
are used to reset, halt, and power the system on or off, regardless of the operating
system or hardware state. The RCM console commands are also used to monitor the
power supplies, temperature, and fans.
The user can enter the RCM console either remotely or through the local serial
console terminal. Once in command mode, the user can enter commands to control
and monitor the system.
To enter the RCM console remotely, the user dials in through a modem, enters a
password, and then types a special escape sequence that invokes RCM command
mode. You must set up the modem before you can dial in remotely. See
Section C.1.1.
To enter the RCM console locally, the user types the escape sequence at the
SRM console prompt on the local serial console terminal.
The RCM also provides an autonomous dial-out capability when it detects a power
failure within the system. When triggered, the RCM dials a paging service at 30-
minute intervals until the administrator clears the alert within the RCM.
