Table 5-5Actions for Open Errors (continued)

Error Code	Explanation	Action
36	Address Verification, Ring Failure: The PC Card,	1 and 2a
	acting as an active monitor, was unable to complete
	the ring purge function successfully. This indicates
	that an error condition has occurred since the
	successful completion of monitor contention (claim
	token), when this PC Card became the active
	monitor.
37	Address Verification, Ring Beaconing: The PC Card	1 and 2b
	has either detected a monitor greaster than or equal
	to contention (claim token) failure or received a
	beacon greater than or equal to MAC frame from
	the ring.
38	Address Verification, Duplicate Node Address: The PC	4
	Card has detected that another station on the ring
	has a PC Card address that is the same as the PC
	card address being tested.
3A	Address Verification, Remove Received: The PC Card	2a and 4
	has received a remove ring station MAC frame,
	indicating that a network management function has
	directed this specific address to get off the ring.
42	Ring Poll, Signal Loss: The PC Card has detected a	1 and 2a
	250-ms signal loss (receiver cannot recognize signal)
	indicating that an error condition has occurred since
	the PC Card successfully completed the ring signal
	recognition phase of the open operation.
45	Ring Poll, Time Out: The insertion timer expired	1 and 2a
	before this function was completed, indicating that
	the ring can be congested, experiencing a high
	bit-error rate, or losing an abnormally high number
	of tokens or frames. This prevents the PC Card’s
	successful reception of either the ring poll request
	or response MAC frame, or transmission of the
	required ring poll response MAC frame.
46	Ring Poll, Ring Failure: The PC Card, acting as an	1 and 2a
	active monitor, was unable to complete the ring

purge function successfully. This indicates that an error condition has occurred since the successful completion of monitor contention (claim token), when this PC Card became the active monitor.
