Table 5-5Actions for Open Errors (continued)

Error Code	Explanation	Action
47	Ring Poll, Ring Beaconing: The PC Card has either	1 and 2b
	detected a monitor contention (claim token) failure
	or received a beacon MAC frame from the ring.
4A	Ring Poll, Remove Received: The PC Card has	2a and 4
	received a remove ring station MAC frame,
	indicating that a network management function has
	directed this PC Card to get off the ring.
55	Request Parameters, Time Out: The insertion timer	1 and 2a
	expired 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 successful transmission of the request
	parameter MAC frame or reception of either the set
	parameter 1 or set parameter 2 MAC frame
	(required response to the PC Card’s request).
56	Request Parameters, 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 (when
	this PC Card became the active monitor).
57	Request Parameters, Ring Beaconing: The PC Card	1 and 2b
	has received a beacon MAC frame from the ring.
59	Request Parameters, Parameter Request - Retry	1 and 2a
	Count Exceeded: The PC Card has detected that the
	ring parameter server is present on the ring but that
	the required response (set parameter 1 or set
	parameter 2 MAC frame) was not received in the
	allotted time. This indicates that the ring can be
	congested, experiencing a high bit-error rate, or
	losing an abnormally high number of tokens or
	frames.
5A	Request Parameters, 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 PC Card to get off the ring.
