Processor Cards
Slots 6 and 7 of the Cisco ONS 15540 ESPx chassis hold processor cards. The
processor cards support redundancy and online insertion and removal. In a
redundant system, the processor cards monitor each other using the Ethernet
backplane and signals. The processor card monitors the fan assembly operation
and airflow temperature. (See
.) During a fan failure or an
out-of-temperature range condition, the processor card activates an alarm. See
for fan assembly status.
