Troubleshooting

A.2 Testing Network Connectivity Using PVCs

The network connectivity tests require that two ATM adapters be connected to an ATM switch fabric with PVCs (as shown in Figure A.2). The carrier lights should be extinguished on the adapters and on the switch fabric, indi- cating that the fibers are OK.

Figure A.2 - Hardware Configuration for Checking PVCs

The network connectivity test suite, shown in Figure A.3, examines higher level functionality after basic adapter board performance has been verified by passing all the tests and checks shown in Figure A.1.
