Troubleshooting
3. Replace the Coordinator Processor Card.
If there are several ControlFiles on the PeerWay, use the following
procedure.
-
To diagnose a ControlFile PeerWay problem with multiple
ControlFiles on the PeerWay:
1. Move the drop cable from one tap connection to another.
WARNING
When moving drop cables and PeerWay Buffer Cards from a
ControlFile for troubleshooting purposes, make certain you
move only those cards and cables associated with the
suspect PeerWay. If anything on the good PeerWay is
disconnected, the ControlFile could be taken off the
PeerWay.
2. Look at the PeerWay Node screen from the Tap Box, and note the
“Noecho” and “Badecho” Fields on the screen. If the problem is
now cleared, replace the Tap Box at your earliest convenience. If
all of the tap connections are used, swap two drop cables at the
Tap Box. Determine if the problem moves to the node that was
swapped. If the problem moved, replace the Tap Box.
3. Swap the PeerWay Buffer Card from this node’s bad PeerWa y
with a PeerWay Buffer Card from the same PeerWay of another
ControlFile. If the problem moves, replace the PeerWay Buffer
Card.
WARNING
If the Coordinator Processor Card is disabled on a running
process, all operator process changes, links running
between controllers in that cage, and links to and from that
ControlFile will freeze at the last value received. The
controllers will continue to operate the process under these
conditions. As soon as the Coordinator Processor Card is
restarted all links will be updated.
4. If the problem does not move to the other ControlFile in step 3,
replace the Coordinator Processor Card in the suspect card cage.
