Alarm display

The alarm code ESA under the PM subsystem header indicates an

emergency stand-alone (ESA) alarm. The *C* indicates a critical ESA

alarm. The absence of the*C* under the ESA indicates a minor ESA alarm.

The number (n) before ESA indicates the number of ESA processors with

the alarm condition.

The number (n) of ESAs that are in the system busy (SysB) or in-service

trouble (ISTb) state.

The SysB condition directly affects service when the OPAC is in ESA.

Local backup does not occur. An interruption of service can occur if the

OPAC 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 a service

interruption if the ESA condition deteriorates.
