Multiple ServSwitch Wizards can be cascaded (connected together in a one-to-
many scheme) in order to increase the maximum number of available CPU ports
in your KVM-switching system. (Note that
each
Wizard in a cascade
must
be
powered through a power supply and
not
from the keyboard interface.) This can
be particularly useful where clusters of computers are located some distance from
each other, because each Wizard acts as a kind of signal booster or repeater and
can be long distances away from the other Wizards in the system.
You can include ServSwitch Wizard LPs, ServSwitch Wizard Pros, and ServSwitch
Duos in ServSwitch Wizard cascades. We don’t recommend including Duos,
however, unless a single ServSwitch Duo is the master switch for your cascade. This
is because users attached to two or more Duos in the same cascade might see the
same CPUs as having different CPU numbers, and might have to use different
commands to access them.
Make sure that your “master” ServSwitch Wizard—the chassis that your monitor,
keyboard, and mouse will be attached to—is unplugged and powered down. If
possible, turn off and unplug all of the devices that you want to attach to this
Wizard. (If you have to “hot-plug” any powered computers into your Wizard
system, see
Section 5.8
.)
Connect your user equipment (keyboard, PS/2 mouse, and monitor) to the
appropriate “control port” connectors on the master Wizard’s rear panel. If you
have had to place the Wizard farther from the user equipment than the
equipment’s native cables will reach—up to an additional distance of 30 ft.
(9.1 m)—you can plug the native cables into ServSwitch Duo User-Extension
Cable. If you need to place your user equipment farther away than that, you’ll need
to use one of our ServSwitch brand KVM extenders.
Now connect a layer of as many as four “subsidiary” Wizards to your master
Wizard by running cabling from the subsidiary Wizards’ control ports to the master
Wizard’s “CPU ports.” This cabling can be either separate male-to-male keyboard-,
mouse-, and video-extension cables, or our three-in-one ServSwitch Duo CPU-
Extension Cable. If you need to run farther than 100 ft. (30.5 m) between master and
subsidiary Wizards, you’ll need to use one of our ServSwitch brand KVM extenders.
You can extend your cascade to a third layer by repeating the process and
attaching additional subsidiary Wizards to the subsidiary Wizards already attached
to your master Wizard chassis. Though it’s theoretically possible to cascade Wizards
to four, five, or more layers, we recommend that you limit your setup to three,
because the addresses you need to enter to switch CPU channels become
ridiculously long. If you need to connect that many computers, use a more
powerful KVM switch such as our ServSwitch™ Affinity or ServSwitch Multi.
