Esa Critical, Minor - Nortel DMS-100 Series Maintenance Manual

Alarm display
Indication
The alarm code ESA under the PM subsystem header indicates an ESA alarm.
The *C* indicates a critical ESA alarm. The absence of *C* under the ESA
indicates a minor ESA alarm. The number (n) before ESA indicates the
number of ESA processors with the alarm condition.
Meaning
The n is the number of ESAs in the system busy (SysB) or in-service trouble
(ISTb) state.
Impact
The SysB condition does not directly affect service. Local backup is not
available. An interruption of service can occur if the OPM cannot contact the
host office and the ESA processor is SysB.
The ISTb condition does not directly affect service. Operating company
personnel must investigate the trouble condition to avoid the possibility of
service interruption if the ESA condition deteriorates.
Common procedures
There are no common procedures.
