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.
