CPU Adapter Cables run from the ServManager 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
).
CAUTION!
Avoid routing cable near fluorescent lights, air-conditioning
compressors, or machines that may create electrical noise. Total length
of original Serv cable from the keyboard, monitor, and mouse to any
given CPU should not exceed 25 ft. (7.6 m). For typical equipment and
video resolutions, length of coaxial cable should not exceed 20 ft. (6.1 m)
from a ServManager to any attached device (keyboard, monitor, mouse,
CPU, or submaster). 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; consult with the
manufacturers of your CPUs about this. To go even farther, you might
want to use Station Extenders (see
Appendix B
) if your common keyboard
and mouse are IBM type.
1.
After you verify that the ServManager is turned off and unplugged, p
lug the
DB25 male connector of the first CPU’s CPU Adapter Cable into the
lowest-numbered CPU port on the ServManager’s rear panel that isn’t
going to be occupied by a submaster Serv type switch. Use consecutively
higher-numbered ports for the rest of the CPUs. For example, if you
planned to put three submasters and three CPUs on an 8-port master
ServManager, you would put the submasters on ports CPU 1 through
CPU 3 (see
Section 3.2.4
), and you would plug the three CPUs into ports
CPU 4 through CPU 6.
2. Plug the 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 ServManager will automatically adjust to
the keyboard mode of IBM compatible CPUs when you power up the
CPU. Avoid plugging CPUs into the ServManager if they are already ON;
if you accidentally do so, see
Section 4.3.7
to make sure the ServManager
is set for the proper keyboard mode.
CAUTION!
Do
not
attach docking stations for ThinkPad
®
or other portable
computers, no matter what type or make, to the ServManager. At the time
of this writing, the ServManager does not support docking stations; your
ServManager system might not function properly if any are attached.
