SERVSWITCH™ JR. MP

3.3 Connecting the CPUs

CPU Cables run from the ServSwitch Jr. MP to the keyboard port, video-output port, and (on PC CPUs) mouse 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).

CAUTION!

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. MP to any attached device (keyboard, monitor, mouse, or CPU). However, we do provide coaxial cable in lengths up to 100 ft. (30.5 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.

1A. SW627A-R2:After you verify that the ServSwitch Jr. MP is powered OFF, plug the DB25 male composite connector of the PC CPU’s CPU Cable into the port labeled “1” on the Switch’s rear panel. Plug the CPU Cable you’re running to the Mac CPU into the port labeled “2”.

1B. SW628A-R2:After you verify that the ServSwitch Jr. MP is powered OFF, plug the DB25 male composite connector of the first PC CPU’s CPU Cable into the port labeled “1” on the Switch’s rear panel. Plug the CPU Cable you’re running to the first Mac CPU into the port labeled “3”. If you’re using a second PC, plug the third CPU Cable into the port labeled “2”; if you’re using a second Mac, plug the fourth CPU Cable into the port labeled “4”.

2.Plug each CPU 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 4.3.10 to make sure the Switch is set for the proper keyboard mode.

NOTE

Newer G3™, G4™, and similar Mac computers have HD15 VGA ports rather than traditional DB15 Mac video ports. If you have such a CPU with ADB (legacy) keyboard and mouse ports, you’ll need to use a Mac Gx type cable (EHN550 or EHN560) to connect it to a Mac port on a ServSwitch Jr. MP. If your G3 or G4 type CPU has USB keyboard and mouse ports instead, call Black Box for technical support.
