20.4 Fault
Log
The unit maintains a time-stamped 200 event fault log in non-volatile memory, this include event acceptance
and clearance, and user logging in and out times. The non-volatile memory has an endurance of greater
than 100,000 cycles.
All faults are logged on separate mainframe fault logs for mainframe-specific faults retained by each
mainframe and a single system fault log retained by the VAR Router, which stores all faults (200 events).
To prevent intermittent or frequently recurring faults from rapidly causing excessive write operations to the
memory, faults are latched so that a recurring fault is logged in its first instance, and thereafter any
repetitions are not recorded, unless a physical manual fault ‘clear’ has taken place.
The fault log is continuously checked, and, if it is found to be corrupted, it is erased and a new ‘LOG
CLEARED’ fault is logged. A manual fault log clearing function is also provided.
