SERVSWITCH BRAND CAT5 KVM EXTENDER FOR SUN
7. Operation
7.1 Keyboard and Mouse Emulation
The ServSwitch Brand CAT5 KVM Extender for Sun uses a microprocessor to
emulate the presence of a directly connected keyboard and mouse for the attached
Sun CPU. This means that you don’t have to connect a keyboard or mouse to the
CPU in order for it to boot; in fact, the CPU will boot with only the Local Unit
connected.
This feature makes several other things possible:
• Your CPU can operate continuously regardless of whether or not the
extender’s Remote Unit is powered, connected, or even present.
• You can “hot-plug” or “hot-swap” the remote or local keyboard and mouse at
any time; that is, you can unplug and replug the keyboard and mouse without
disrupting the operation of the CPU.
• You can connect different Local Units to different Remote Units at different
times in order to create a “switched” KVM-extension system with multiple user
stations. You can do this by moving cable between patch-panel ports or directly
between units, although you should do this as infrequently as possible to avoid
wearing out the connectors on your cable and devices. Or you can use a CAT5
switch, but the switch must carry all eight wires (maintaining the twists between
the wire pairs) and must have enough bandwidth to support your system’s
video demands. Please call Black Box Technical Support to discuss your
application before installing such a system.
7.2 The Scroll-Lock Reset
In an extender system, you can reinitialize the keyboard and the associated mouse
after you detach and reconnect either of them, or if either of them ever lock up.
Do this (at either the local or remote station) by pressing and holding the right
[Shift] key, pressing and releasing [Scroll Lock], and releasing right [Shift]. (Note
that the extender will automatically reinitialize the keyboard and mouse whenever
you attach them.) If a Scroll-Lock reset doesn’t help your remote keyboard or
mouse, try cycling power to the Remote Unit.
