5.5 Fault-finding
5.5.1 Unit Faults
The MX8400 Multiplexer monitors and report errors on all major items (such as fans,
power supplies and option cards) and monitors its internal temperature.
All faults are logged and not lost during a power failure. All internal logs are stamped
with the time and date.
Any abnormal condition that does not impact directly on the MX8400’s operation is
flagged as a warning. This includes conditions like single fan failure or switched to
redundant input where the unit will continue to operate but should be investigated.
It is possible to set each alarm condition to be ignored, raised as a warning or an
alarm. All alarms and warnings are made available to the user via the nCompass
Control system.
A list of reported unit faults is shown in Table 5.1.
