SERVSWITCH™ ULTRA
4. Operation: Hardware and
Keyboard Commands
The first part of this chapter,
Section 4.1
, gives you some guidelines that you
should follow to make sure your ServSwitch Ultra works properly with your
equipment.
Section 4.2
summarizes the ServSwitch Ultra’s keyboard commands, and
Section
4.3
describes these commands in detail.
Section 4.4
outlines how you can select ports or upgrade firmware from an
optional computer or terminal connected to the ServSwitch Ultra’s RS-232 port.
NOTES
If, as you prepare to operate the ServSwitch Ultra, you see a prompt on
your screen asking you to “Enter password,” you must type in the
unit’s access password before the ServSwitch will allow you to enter
commands. See
Section 5.5.2
.
To start any ServSwitch Ultra keyboard command, you must press and
release the left Control Key ([Ctrl]). Pressing and releasing [Ctrl] cues
the Switch to expect command characters from the keyboard. You then
have two seconds in which to start entering a valid command. If no
command is begun within two seconds or if an invalid command is
entered, the ServSwitch aborts the command.
When entering commands that contain numbers or math symbols, use
only the numeral keys located at the top of your alphanumeric keyboard.
Numbers and symbols entered from the numeric keypad to the right will
not be recognized as valid.
4.1 Guidelines for Using the ServSwitch Ultra with Your Equipment
4.1.1 CPU
S
For your IBM PC type CPUs, use only IBM PC/AT or PS/2 or 100% compatible
machines. The ServSwitch Ultra does not support IBM PC/XT™ or compatible
machines. It does not support machines that output CGA or EGA video. (Because
the basic hardware design for Sun and Apple CPUs has remained backward-
compatible, the ServSwitch Ultra supports all Apple and Sun machines.) Any SGI
machines you attach must output the current type of SGI video on 13W3
connectors or standard VGA video on HD15 connectors.
