Command Function
clr Resets all MSC options to their power-on defaults. This includes echo mode, no
heartbeats, and so forth.
ech 0 Turns off echoing as MSC commands are entered; what you type does not appear
onscreen.
ech 1 Turns on echoing. You see what you type.
ech Toggles the echoing. (Echoing is on by default after the system is reset.)
fan Checks the speed of the fans. The command displays an n if the fans are operating
at a normal speed, and an h if the fans are operating at a high speed. Note that
the MSC automatically switches the fan speed to high if one of the fans fails or if
the ambient air temperature is between 83.3˚ F (28.5˚ C) and 104˚ F (40˚ C).
fan n Sets the fans to run at normal speed.
fan h Sets the fans to run at high speed.
nmi Sends a hardware nonmaskable interrupt (NMI) to the system.
pas xxxx Enters Supervisor mode; xxxx is the four-character password for your system. All
Origin200 servers ship with the word "none" as the default password.
pas s xxxx Sets the password to xxxx. Note that the password must be exactly 4 characters
long.
pwr Displays u if the power is on and d if the power is off.
pwr u Turns on power to the drives, logic carrier, fans, and PCI boards.
pwr d Turns off power to the drives, logic carrier, fans, and PCI boards.
pwr d N Waits N seconds and then powers the system off. N is a hexadecimal value from
5 to 258 (5 to 600 decimal).
pwr c N Waits N seconds and then powers the system on. N is a hexadecimal value from
5 to 258 (5 to 600 decimal).
rst Sends a hardware reset to the system.
sel cpu Selects the CPU to receive input from the MSC. Anything typed on the MSC that
is not an escaped command is sent through to the selected CPU. CPUs are named
by module and slice. For example, sel 1a selects CPU A in module 1 for input,
and sel 2b selects CPU B in a second (slave) module.
