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> K n [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 “RESET
Addr ” 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> RESET Addr [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.
