An intermittent problem is a problem that occurs for a short time,
and then goes away.
The problem may not occur again until some time in the future,
if at all. Intermittent problems cannot be made to appear again easily.
Some
examples of intermittent problems are:
- A reference code appears on the control panel (the system attention light
is on) but disappears when you power off, then power on the system. An entry
does not appear in the Product Activity Log.
- An entry appears in the problem log when you use the Work with Problems
(WRKPRB) command. For example, the 5094 expansion
unit becomes powered off, but starts working again when you power it on.
- The workstation adapter is in a hang condition but starts working normally
when it gets reset.
Note: You can get equipment for the following conditions from your
branch office or installation planning representative:
- If you suspect that the air at the system site is too hot or too cold,
you need a thermometer to check the temperature.
- If you suspect the moisture content of the air at the system site is too
low or too high, use a wet/dry bulb to check the humidity. See General intermittent problem checklist for
more information.
- If you need to check ac receptacles for correct wiring, you need an ECOS
tester, Model 1023-100, or equivalent tester. The tester lets you quickly
check the receptacles. If you cannot find a tester, use an analog multimeter
instead. Do not use a digital multimeter.
