CPU Cables run from the ServSwitch Affinity to the keyboard port, mouse port (if
this is separate), 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 3.2.3).
1. Make sure that the Affinity is turned off and unplugged.
2. For Mac CPUs: Plug a ServSwitch Micro Mac Converter (KV99MCON) into
each of the CPU ports on the Affinity’s rear panel that you’ll be connecting to
a Mac CPU.
3. Take the CPU Cable you’ll be running to the first CPU and plug its DB25
male connector into one of the CPU ports on the Affinity’s rear panel
(preferably the lowest-numbered one—refer to Figures 2-2 and 2-3 in
Section 2.3), or into the Mac Converter attached to the port if the cable is
going to a Mac. Use the other (consecutively higher-numbered) CPU ports
for the rest of the CPU Cables.
4. For Mac CPUs that don’t output VGA-compatible video: As described on its
installation sheet, set a Mac Video Adapter for ServSwitch (KV99MA) to
emulate the proper monitor for each of your Mac CPUs, then attach the
adapter to the Mac CPU’s video port. (Keep in mind that unless all of your
CPUs are Mac type, you’ll need multisync monitors at your user stations.)
5. If all of the CPUs you will be attaching to your Affinity system are Sun models, and
none of the monitors you want to use support 640 x 480 resolution: Take the CPU
Cable attached to the Affinity’s lowest-numbered CPU port. Plug the video
strand of this cable into the video port of a powered and operating Sun CPU
that is outputting video in a resolution that at least one of your user-station
monitors supports. (You can also unplug this CPU’s keyboard and mouse and
attach the keyboard/mouse strand of the CPU Cable instead, but be aware
that this will cause the CPU to suspend normal operation and go into a
locked-up “panic mode.” To recover the CPU from this mode when you’re
ready to power the system, turn the Affinity system ON, select that CPU, and
type in the proper character sequence—usually “OK” [Enter].)
This step is necessary in order for the Affinity’s on-screen display to be
properly synchronized when the Affinity is powered up, so that it will then be
possible to configure all of your CPU ports for Sun keyboard and mouse. If
you skip this step, it will cause a series of hardware and firmware
incompatibilities that will prevent your Affinity system from working. To avoid
this complication altogether, we strongly recommend that you use multisync
monitors rather than monitors that don’t support 640 x 480 resolution.
