When CNET_fault_code > 0, CNET_fault = 1, and Global_fault = 16 (if
no higher global faults are active).
Note: There are two CNET plug card LEDs – one for channel A and
one for channel B. Because these LEDs are internal to the CNET
fiber optic plug card, they are not readily visible on this type of
plug card.
If a cable is connected to the network access port (NAP) of the CNET
plug card, the state of the LEDs is meaningless.
Plug Fault
A CNET Communications fault (CNET_fault_code = 4) indicates that a
problem internal to the CNET plug card has caused the card to fail. This
fault occurs during CNET initialization.
When CNET_fault_code = 4, Global_fault = 16, CNET_fault = 1,
CNET_status = 3 and both CNET plug card LEDs are solid red.
Note: There are two CNET plug card LEDs – one for channel A and
one for channel B. Because these LEDs are internal to the CNET
fiber optic plug card, they are not readily visible on this type of
plug card.
If a cable is connected to the network access port (NAP) of the CNET
plug card, the state of the LEDs is meaningless.
To handle or clear this fault:
•
