SERVSWITCH™ ULTRA
of the keyboard marked with [–] and [_]). The command is not case-sensitive. Do
not use the [+] and [–] keys on the keyboard’s numeric pad; the Switch doesn’t
recognize these.
You can also select the next or previous port manually from the ServSwitch
Ultra’s front panel by pushing the button labeled “
” or “” respectively (“+” or
“–” on the 2-port units). Each time you press the button, the next or previous port
in sequence is selected.
4.3.3 S CAN M ODE
To start scanning (switching from CPU to CPU in a continuous rotation) from the
keyboard, press and release the left Control key ([Ctrl]), then press [S]. The
ServSwitch Ultra will begin scanning sequentially from its currently selected port
through the higher-numbered ports, then begin again at CPU Port 1. As it scans, it
delays 1 to 15 seconds at each port. (This “Scan-Delay Time” is user-selectable; see
Section 5.2.6.) To stop scanning, press and release [Ctrl], then press [X]; you can
also stop a scan by entering a Select Port command. ServSwitch Ultra letter
commands are not case-sensitive: You can enter upper- or lower-case letters.
To disable scanning, set the scan-delay time to zero; see Section 5.2.6.
4.3.4 K EEP S ETTINGS
The Keep Settings command saves the current state of the ServSwitch Ultra’s two
keyboard-selectable settings (“Set Screen-Saver Interval” and “Transpose Command
and Alt Keys,” described in the next two sections) to nonvolatile memory
(NVRAM), where they become the new default (loaded at power-up) settings. To
enter the command, press and release the left Control key, then type [K].
4.3.5 S ET S CREEN -S AVER I NTERVAL
This feature reduces the wear on your shared screen and provides security for your
system by blanking the screen when there has been no keyboard activity for a
specified length of time. To set the screen-saver interval, press and release the left
Control key, type [V] followed by the interval time in seconds (1 to 999, or 0 to
disable the screen saver), and press [Enter]. Issue the Keep Settings command
after you enter this command.
To reactivate the screen when it’s been blanked, press any key on the keyboard
or move the mouse. The default setting of this option is 0 (screen saver disabled).
NOTE
When the ServSwitch Ultra is in the Screen-Saver state, all of its
SELECT LEDs (the left-hand, red port LEDs) will be OFF.
