CHAPTER 5: Troubleshooting
D. If your CPU is producing composite sync and your monitor accepts only
separate horizontal and vertical sync (or vice versa), try swapping in a
matching monitor or CPU, or a monitor that will aceept both sync types. If
this is not an option, call Black Box for technical support; we might be able to
give you a quote on a sync converter and special cabling.
E. If the video problem is not centered on the monitor, check the video
strands of your cables. Tighten any loose connections.
F. If no cable connectors are loose, begin swapping your cables one at a time.
If the problem goes away when you substitute a cable, the old cable is
probably defective.
G. If swapping cables doesn’t solve the problem, try plugging the CPU into a
different CPU port on the ServManager or submaster. If the problem goes
away when the CPU is connected to a different port, the old port is probably
defective.

A. If you’re using XGA, you must use coaxial cables (see Section 4.1.3 and
Appendix B ).
B.
Check your video driver. It might not be set up correctly for your desired
resolution. This might be true even for Mac or Sun CPUs.

A. The Units value might not be set correctly. (If any of the CPUs you can
access are receiving garbage characters, this is a good indicator.) Try setting it
now (see
Section 4.3.10 ).
B. The Maximum Ports or Width value might not be set correctly. Try setting
it now (see Sections 4.3.8 and 4.3.9 ).
