RLCM alarm clearing procedures

critical, minor

Alarm display

The alarm code ESA under the PM subsystem header indicates an 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 n is the number of ESAs in the system busy (SysB) or in-service trouble

(ISTb) state.

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

There is no local backup. An interruption of service can occur if the RLCM

cannot contact the host office and the ESA processor is SysB.

The ISTb condition does not directly affect service. Investigate the trouble

condition to avoid a possible service interruption if the ESA condition

deteriorates.
