When you place it in “scan mode,” the ServSwitch Elite automatically switches the
video connection sequentially from port to port (computer to computer), so you
can observe the state of any or all of the computers in the system.
Instead of sequential uniform scanning, you can set up a scan mode that
includes specific computers in, or excludes them from, the scan. For this custom
scan mode, you can specify that the computers be scanned in a given sequence,
and for variable durations. Refer to Section 4.2.6.
To place the Switch in the scan mode, take these steps:
1. Press [Print Screen]. The
SERVSWITCH ELITE
window appears.
2. Press [F2] and the
FUNCTIONS
window appears. The Commands menu will be
displayed and its first entry (
SCAN
) will be highlighted.
3. Press [Enter]. At this point, the Switch enters scan mode and the display
returns to the status flag. You can press [Esc] (escape) at any time prior to
pressing [Enter] to cancel the operation.
To get out of scan mode, press any key on the keyboard or move the mouse. The
scan stops at the currently connected computer.
On the ServSwitch Elite 4x8 (KV7148FA), each of the four consoles can scan the
system independently. You can scan computer ports controlled by other consoles if
those ports are on a master or single Switch; however, if you try to scan any port on
the same slave Switch as a port controlled by another console, or if you try to stop
the scan at a port controlled by another console, the Switch will react in one of two
ways depending on the setting of DIP switch F (see Section 3.2):
• In the factory-default “cooperative” setting, the Switch will not let you stop
your scan on any computer port controlled by another console. You will
instead be “deselected”—not connected to any port, with video blanked—until
you select a different port. If you try to scan any port on the same slave Switch
as a port controlled by another console, you will not see anything (the video
will be blank).
• In the “preemptive” setting, if you stop your scan on a port controlled by
another console—or even if you scan any port on the same slave Switch as a
port controlled by another console—the Switch will connect you to that port
and will deselect the console that was in control of that port, or the other port
on that slave—instead.
