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.
Communicating by Serial Port, on page 88, outlines the procedures for connecting
to the SSU-2000 using the Comms module serial ports. Communicating by
Ethernet, on page 90, outlines the procedures for connecting via the Ethernet
connection. Appendix A, Alarms and Events, details event and alarm descriptions,
default event and alarm levels, status messages and corrective action
