100VG-AnyLAN and 100Base-T Error Messages
SDI Driver Specific Status Values
ACTION: None. This error can usually be ignored. Power failures can
occur at any moment. The driver was executing at the moment power
failed. Power then returned, and the driver ran to completion, noticing
this error along the way. Upon exit, the driver was then officially
notified of a powerfail by MPE. The driver then attempted powerfail
recovery, and should now be operating the same as before.
The link did not connect. If you suspect power did not really fail but the
problem persists, the adapter card may be faulty. If retrying the connect
does not help, replace the adapter card.
MESSAGE 2: MII read error on adapter card.
3040 CLAS0001 CAUSE: During a 100VG-AnyLAN link connect attempt, the driver
attempted to request a training interval from the hub, but its read from
an MII hardware register on the adapter card failed to return the
proper acknowledgment bit.
ACTION: The link did not connect. MII reads can be sensitive to
software timing. If you have GLANCE or a similar tool, run it and check
the CPU load on the system. If the load is high, try reducing the CPU
load, then retry the connect. If the problem persists, the adapter card
has probably failed; replace the adapter card.
MESSAGE 2: Link connected.
3070 CLAS0002 CAUSE: The first upper layer subsystem to bind to the driver triggered
a link connect, which was successful (“Mode”= the connection mode:
100VG, 100Base-TX, or 10Base-T “Duplex”= Full or Half). This event is
also logged after the link or cable has been successfully reconnected
after being disconnected, or on a link reconnect following a hub retrain,
severe line-hit, power failure, or other recoverable error.
ACTION: This event is informational only.
No action is needed unless the message appears frequently while the
link is up, indicating possible cabling problems; make sure cabling is
securely connected and properly routed away from sources of
interference, and is of the proper UTP category or grade for the type of
link (CAT-5 for 100Base-T, CAT-3 or -5 for 100VG-AnyLAN).
MESSAGE: Link disconnected.
3100 CLAS0002 CAUSE: The last upper layer subsystem has unbound itself from the
driver, triggering a link disconnect This event is also logged if the link
unexpectedly drops due to a cable disconnect, hub retrain request,
powerfail, severe line hit, or other recoverable error (“Status”= 32-bit
status giving the reason for the disconnect, 0=normal).
ACTION: This event is informational only. If the network is being shut
down, no action is required.
