Chapter 9 Viewing and Responding to Alarms
Viewing and Responding to Alarms Using Physical Switch Controls
System Status Green Blinking green indicates that the card is in the active state.
Yellow Slow blinking yellow indicates that the card is in the standby
state.
Fast blinking yellow indicates that the card is in the boot
state.
Red Solid red indicates that the card is in the Reset state, the card
has failed, or a back card is missing.
Blinking red indicates that the card is downloading new
software.
CR
(Critical alarm)
Blue A critical alarm indicates a condition that results in a loss of
service for which the switch cannot correct. For example,
when APS redundancy is not present, a broken trunk cable
generates a critical alarm. Immediate action is required.
MJ
(Major alarm)
Red A major alarm indicates a component or service failure that
currently has minimal impact on service. For example, if one
card in a redundant AXSM configuration fails, the good card
takes over and the switch displays a major alarm. Urgent
action is required to recover the failed component or service.
MN
(Minor alarm)
Yellow A minor alarm indicates a non-service affecting condition
that should be corrected. Minor alarms can indicate internal
switch failures, such as the failure of a single fan, or external
failures that cannot be corrected at the switch.
HIST
(History)
Green Green indicates that a network alarm occurred. Critical and
major alarms clear automatically when the problem is
resolved. Minor alarms remain lit until cleared with the
history button. If there are critical or major alarms in
progress, you cannot reset the HIST light. If the card
indicates a minor alarm, press the HIST button once to see if
the alarm condition has passed. When all alarms are cleared,
press the HIST button to turn off the HIST LED.
ACO
(Alarm cut-off)
Yellow Yellow indicates that the ACO switch was pushed to clear the
audible alarm indicator, but the alarm condition still exists.
DC-A Green Green indicates that the power supplies in tray “A” are
functioning.
None No light indicates that power supply tray “A” is empty (no
power modules).
DC-B Green Green indicates that the power supplies in tray “B” are
functioning.
None No light indicates that power supply tray “B” is empty (no
power modules).
ENET
(Ethernet)
Green Blinking green indicates that there is activity on the LAN
Control Port.
