72 SD Series Technical Manual MDS 05-4846A01, Rev. D
Both setting and clearing of major/minor alarms and status conditions
are logged, as well as informational events (i.e., remote rebooted, repro-
gramming in process, etc.).
Major Alarms vs. Minor Alarms
Major Alarms report serious conditions that generally indicate a hard-
ware failure, or other abnormal condition that will prevent (or seriously
hamper) further operation of the transceiver. Major alarms generally
indicate the need for factory repair. Contact your factory representative
for further assistance.
Minor Alarms report conditions that, under most circumstances will not
prevent transceiver operation. This includes out-of-tolerance conditions,
baud rate mismatches, etc. The cause of these alarms should be investi-
gated and corrected to prevent system failure.
Status and Informational Events
Status events indicate current states or conditions that are not errors.
They are used merely to indicate process functions (i.e., Reprogramming
in Process).
Informational (Info) events pertain to those items which have occurred
since bootup. They may or may not indicate an error, and they do not
show current conditions, just an even that occurred at some point after
boot-up (i.e., Event #32 Booting Up).
Event Code Definitions
Table 15 contains a listing of event codes that may be reported by the
transceiver. The codes shown are a subset of a larger pool of codes used
for various GE MDS products. For this reason, the table does not show
a sequential listing of all code numbers. Only the codes applicable to
this product series are shown.
