You can access the RMC through either of two serial lines: the standard console
terminal COM1 (MMJ) port or the RMC modem port (9-pin DIN).
• To enter the RMC console remotely, dial in through a modem, enter a password,
and then type a special escape sequence that invokes the RMC command mode.
The default escape sequence is ^[^[rcm. This is equivalent to
<Esc><Esc>rcm, where <Esc> is the escape key on a PC keyboard. The
default string can be changed using the set escape command. Before you can
dial in remotely, you must set up the RMC initialization and dial strings. Refer
to Section 4.2 for first-time setup instructions.
• To enter the RMC console locally, type the escape sequence at the SRM console
prompt on the local serial console terminal.
You can also enter the RMC console from the local graphics monitor by
entering the RMC command at the SRM console prompt, and then entering the
escape sequence. When finished accessing the RMC console from the graphics
monitor, enter the reset command to restore the RMC and SRM consoles.
Once connected to the RMC, the operator can use a special set of remote console
commands, distinct from the standard SRM and AlphaBIOS consoles. The RMC
firmware is implemented in a dedicated microprocessor (RMC PIC processor). The
RMC commands allow the operator to remotely monitor power supply status, system
temperature, and fan status.
RMC commands also allow the remote operator to exercise control over the system,
equivalent to using the system control panel: Power off/on, Reset, and Halt (in/out).
The RMC logic can dial a preset telephone number when it detects system alarm
conditions. A typical scenario might be:
1. RMC detects an alarm condition due to excessive temperature.
2. RMC dials the operator’s pager and sends a message identifying the system.
3. Operator dials the system from a remote serial terminal.
4. Logging into the RMC, the operator checks system status and powers down the
system.
5. Later the operator powers up the system and reboots.
