Troubleshooting
Diagnosing a Console or SCI PeerWay Problem
-
To diagnose a Console or SCI PeerWay problem:
1. Move the drop cable from one tap connection to another.
CAUTION
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. If the problem is now cleared,
replace the Tap Box at the 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.
2. Replace the Console PeerWay Interface Card.
3. Replace the Console Power Regulator Card.
4. Replace the drop cable.
5. Command Console and Basic Command Console only: Pull the
console card cage out and connect the drop cable directly to the
back of the motherboard, bypassing the short marshaling panel
cable. Use extreme caution when removing and installing the
console c ard cage to avoid damaging any cables.
