Troubleshooting

The SSU-2000 incorporates many alarms and event messages to alert that a
possible problem exists. These alarm and event message reports can be accessed
via the Communications module serial ports using a dumb terminal or PC.
Communication may also be established using the RJ-45 Ethernet connector
(ETHERNET 10-BASE-T) on the connector interface panel of the chassis.
