Notes:
a. Error Type 1This error indicates the circuit pac k totally stopped
functioning or it was physic ally removed from the system.
NOTE:
The alarm is logged ap proximately 11-minutes after the circuit p ack
is removed/SAKI Sanity Test (#53) fails.
If the circuit pac k is not present in the system, insert a circu it pack in the
slot indicated b y the error to resolve the error.
If the circuit pac k is present in the system, it is faulty and must b e
replaced. See the preced ing section,
How to Replace the Tone-Clock
Circuit Pack
.
If the faulty circuit pac k is in standby mode, a MINOR alarm is raised , but
no other system action is taken. If the circ uit pack is the active Tone-Clock,
further effects of this error depend on the Reliability Option for the switch.
If an interchange is attempted and the system is unable to ac tivate the
standby Tone-Clock, Emergency Transfer is activated. If th e problem is in
the PPN the entire system is affected. Otherwise only the EPN in question
is affected. When this happens, b oth circuit pac ks are faulty and must be
replaced. See the preced ing section,
How to Replace the Tone-Clock
Circuit Pack
.
If a successful interchang e occurs in response to a failure of the active
Tone-Clock, or if a standby Tone-Clock fails, the faulty Tone-Clock should
be replaced.
b. Error Type 18The indicated Tone-Clock circuit pack has been made
unavailable via the busyout tone-clock PC command . This error applies
only to High or Critical Reliability syste ms (an active Tone-Clock may not
be busied out). To resolve this error, execute release tone-clock PC.
c. Error Type 23The circuit pack has b een logically admi nistered but not
physically installed. Ins talling the circuit pac k will resolve the alarm.
