8.15 Other Commands: System Control and Maintenance

The ServSwitch Multi supports a number of other keystroke-sequence commands for system control and maintenance:

Command	Function
<CM>CHASSIS=n[Enter]	Cascaded systems only: Sets the unit address of the local ServSwitch Multi (the
	one your console is attached to) to n (a number from 0 to 254). If you have
	Transmit Cards installed in all of your Switches, you won’t need to issue this
	command; the Switches’ unit addresses will be set on the Cards’ DIP switches
	(see Section 6.3.1). If more than one of your Switches have only Receive Cards
	installed in them, however, you will have to issue this command to set them to
	unique addresses in order to view or update the firmware of Cards or local-
	console modules installed in them (see Section 8.13). (This is because the
	factory-default unit address of all ServSwitch Multis is zero, and it remains zero
	for any given Switch—unless you install a Transmit Card in it—until you issue
	this command.)
	If you send this command to a Switch with any Transmit Cards installed in it,
	and n does not match the address setting of those Cards, that Switch will
	behave as if you’ve installed a Transmit Card with a non-matching address in it:
	The LEDs of all Transmit Cards in that Switch will start blinking, and you’ll
	have to either issue another CHASSIS=n command or physically change the
	unit-address settings of the Cards to get that Switch working again.
<CM>Kn[Enter]	Sets the scan mode (n = 1, 2, or 3) of the keyboard signals the Switch should
	send to the currently selected IBM PC compatible computer. Scan mode 2 is
	used by the vast majority of CPUs, and is also the default state of all 101-key and
	PS/2 keyboards. Mode 1 is used primarily by certain older PS/2 CPUs. Mode 3
	is used by RS/6000 CPUs, some other PC type UNIX® based computers, and
	certain specialized servers. Issue this command if your computer is behaving in
	a way that seems to indicate that it is misinterpreting what you’re typing.
<CM>M+[Enter]	Re-enables your mouse for use with the currently selected channel. Issue this
	command after you attach a different type of mouse to your console or after
	you send the “RESET” or “RESETAddr” command (see below) to the currently
	selected computer channel.
<CM>OFF[Enter]	Logs you off of the system: Your console deselects your previously selected
	computer channel—freeing up a data pathway through the switch if you were
	an independent user—and your monitor screen goes blank. The monitor is not
	reactivated again until a channel is selected from your console.
<CM>RESET[Enter]	Resets your console’s User-Interface Card. You might have to enter the “M+”
	command (see above) afterward to get your mouse working properly.
<CM>RESETAddr[Enter]	Resets any User or CPU-Interface Card in the system.
<CM>SAVE[Enter]	Saves your console’s Follow Leader and Swap Partner settings (if any; see
	Sections 8.8 and 8.9) to the ServSwitch Multi’s nonvolatile memory. Unless
	these settings are saved, they’ll be lost if the Switch loses power or is turned
	OFF.
