Troubleshooting
Diagnosing a ControlFile PeerWay Problem
The procedure for checking PeerWay problems differs if there is one
ControlFile or several ControlFiles on the PeerWay.
-
To diagnose a ControlFile PeerWay problem with one ControlFile
on the PeerWay:
1. Move the drop cable from one tap connection to another.
WARNING
When moving drop cables and PeerWay buffers from a
ControlFile for troubleshooting purposes, make certain you
move only those associated with the suspect PeerWay. If
anything on the good PeerWay is disconnected, the
ControlFile or console could be taken off the PeerWay.
Look at the PeerWay Node screen for this device, and note the
“Noecho” and “Badecho” Fields on this screen. If the problem is
now cleared, replace the Tap Box. 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.
2. Remove the PeerWay Buffer card from the ControlFile on the
faulty PeerWay. Follow step a or b below depending on the part
number of the card.
a. Part number 1984--1402--0003: The card must be replaced to
determine if it is bad. If no spares are available, the c ard can
be swapped with the other buffer in this cage. This will take
the node off of the PeerWay.
b. Part number 1984--1502--0001: Remove the card and move
the s even jumpers (HD 2, 3, 4, 5, 6, 7, and 8) on the card to
the TEST position. Install the card and look at the PeerWay
Node screen and determine if the N oecho and Badecho
Fields are at 0. If they are now at 0, the PeerWay Buffer Card
is bad and must be replaced.
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.
