Diagnosing Problems with ATM Modules
If the cause of a Phase 2 problem is not due to the 6416SW console connection, make
sure that all ATM modules are operational by following these steps:
1. Enter the SHOW MODULE ALL command as described in the
ONcore Switching
Hub/CELLplex 4000 ATM Command Reference Guide
.
2. Check that each module is installed, connected, and functioning properly. Normal
operation is indicated when Y appears in the Install, Connect, and Operation
columns for all slot numbers except the row where <extension> appears. In the
row for this slot, normal operation is indicated by Y in the Install column and n in
the Connect and Operation columns.
3. If n appears for Install, make sure that the module is properly plugged into the
backplane connectors in the hub.
If n appears for Connect, use the SET MODULE command to reconnect the module
for ATM traffic.
If n appears for Operation, the module, slot, or backplane may be faulty. Insert the
module into other slots to see if the slot or backplane is the cause.
If the problem persists, enter the SHOW MODULE VERBOSE command to display
more detailed information on the module's status.
4. If the status of the module in the SHOW MODULE VERBOSE screen is hardware
KO and permanent failure, reset the module. If the problem persists and if the
module's status does not change to hardware okay and normal, replace the module.
If the module's status continues as under recovery for a long time, reset the
module. If the problem persists, replace the module.
