SERVSWITCH™ JR.
3.3 Connecting the CPUs
CPU Adapter Cables run from the ServSwitch Jr. to the keyboard port, mouse port,
and video-output port of each CPU you want to directly attach to it. Different types
of this cable fit the connectors on different computers (see Appendix B). This
cable also comes in the different lengths supported by different applications (see
Section 4.1.3).
Avoid routing cable near fluorescent lights, air-conditioning
compressors, or machines that may create electrical noise. Total length
of original Serv cable from a ServSwitch Jr. to any given CPU should not
exceed 20 feet (6.1 m). For typical equipment and video resolutions,
length of coaxial cable should not exceed 20 ft. (6.1 m) from a
ServSwitch Jr. to any attached device (keyboard, monitor, mouse, or
CPU). However, we do provide coaxial cable in lengths up to 50 ft.
(15.2 m), because some CPUs can drive and receive keyboard and
mouse signals at greater distances than others. To go even farther, you
might want to use Station Extenders or CAT5 KVM Extenders (see
Appendix B), but please call Black Box Tech Support to discuss your
application.
1. After you verify that the ServSwitch Jr. is powered OFF, plug the DB25 male
composite connector of the first CPU's CPU Adapter Cable into port 1 on the
Switch's rear panel. Plug the Adapter Cable you're running to the next CPU
into port 2; if your Switch has more ports, plug the third CPU Adapter Cable
(if necessary) into port 3, and so on.
2. Plug each CPU Adapter Cable's video-, keyboard-, and mouse-port connectors
into the corresponding ports on the CPU. The CPU should be OFF when you
do this; the Switch will automatically adjust to the CPU's keyboard mode
when you power up the CPU. Avoid plugging CPUs into the Switch if they are
already ON; if you accidentally do so, see Section 4.3.11 to make sure the
Switch is set for the proper keyboard mode.
Do not attach docking stations for ThinkPad
computers, no matter what type or make, to the ServSwitch Jr. The
ServSwitch Jr. does not support docking stations; your Switch system
might not function properly if any are attached.
Even if you connect your ThinkPad directly (rather than through a
docking station) to the keyboard, video, and mouse feeds from the
ServSwitch Jr., it still won't work, because the Switch supports only
"stream mode" (continuous) mouse data but the ThinkPad has to see
"prompt mode" (burst-on-request) mouse data.
