OPERATION
The firmware revision level identifies the firmware version (the system
software contained in EPROMs).
A memory status message is Passed (message is on steady) or Failed
(message is flashing), and indicates whether the memory passed certain
tests. A RAM failure is also indicated by flashing front panel indicator
BPV, and a ROM failure is also indicated by flashing front panel indi-
cator LB. Any failed memory should be considered a potentially serious
problem and the pc card should be replaced. Use of the Supervisory termi-
nal is prohibited during a failed memory condition. Supervisory termi-
nal operation may be restored and the memory problem may be temporar-
ily corrected by powering off the CSU and then powering it on. If the prob-
lem cleared, the CSU and Supervisory terminal should be operational.
The CSU address number (000 to 255) identifies the CSU to which you are
connected. This address is defined by option switches S4-1 to S4-8.
