CHAPTER 9: Troubleshooting
Your video is OK in low-resolution mode, but you can’t get into high-resolution
mode.
A. If you’re using XGA, you must use coaxial cables (see Section 3.2.3 and
Appendix B).
B. Check your video driver or control panel. It might not be set up correctly for
your desired resolution.
Your on-screen display is not synchronized.
There might be a sync mismatch between a CPU and the monitor; for example,
perhaps the CPU is sending video with composite sync or sync on green and the
monitor only accepts horizontal or vertical sync. Change the settings of the CPU or
monitor so that the two are compatible. If this is not possible, swap in a different
monitor that can handle all of your CPUs’ synchronization types.
The Affinity doesn’t work with your docking station.
The Affinity does not support most docking stations for portable computers.
The Affinity doesn’t work with your dongle-protected software.
The Affinity does not support most dongles (the devices
required to be inserted
into the keyboard line by some software for copy protection).
The Affinity doesn’t work with your IBM ThinkPad.
The Affinity supports only “stream mode” (continuous) mouse data. It doesn’t
support the “prompt mode” (burst-on-request) method for handling mouse data
that some older IBM ThinkPad models use, regardless of whether the ThinkPad is
connected to the Affinity directly or through a docking station (and see the text
under “The Affinity doesn’t work with your docking station” above).
Your Dual-Powered Affinity is plugged in but its front-panel LEDs are not all lit.
If your Dual-Powered Affinity is plugged into a pair of working outlets with good
power cords, but one or more of the POWER MONITOR LEDs on its front panel
are dark, there has been a hardware failure. If LED 1 is dark, power supply #1 (the
upper transformer) has failed. If LED 2 is dark, power supply #2 (the lower
transformer) has failed. See Section 9.2 if you need to replace a failed supply.
If LED 1 or 2 is lit but the SYSTEM LED is dark, diodes inside the chassis have
failed. Contact Black Box as described in Section 9.3 to arrange for the chassis to
be repaired or replaced.
