Yellow Yellow indicates a Minor Network alarm in the node. A minor alarm is used when a non-service affecting condition has occurred. Minor alarms should be investigated to determine if the problem has the potential to affect service. 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. Yellow Yellow indicates that the ACO switch was pushed to clear the audible alarm indicator, but the alarm condition still exists. Green Blinking green indicates that there is activity on the LAN Control Port. AXSM Card Controls Figure 9-2 shows the LEDs available on the front of the AXSM card.
