(The fan and power lead is an O-ring of every cabinet’s status lead.) Since
an error condition on a fan’s or power supply’s output could be the result of
a temporary overload (e.g., during board insertion) or caused by the
equipment’s location (e.g., fan blockage), a single event may be an
anomaly that eventually clears. However, a repeating condition causes a
major alarm.
On-Demand Tests: Descriptions and Error Codes
Always investigate tests in the order presented in the following table. For
example, by clearing error codes associated with the RMC Power/Fan Query test,
you may also clear errors generated from other tests in the testing sequence.
Test descriptions and recommended maintenance procedures follow for every
error that can occur during on-demand testing.
Notes:
a. Refer to ‘‘Analog Ring Generator Initialization Test (#117)’’ on page 8-1010
for a description of this test.
b. Refer to ‘‘Analog Ring Generator Query Test (#118)’’ on page 8-1011 for a
description of this test.
