Alarm Collection and Display
The ONS 15454 has several methods to alert you to possible problems with the
node.The ONS 15454 faceplate has LEDs that alert you to critical, major, minor,
or remote alarms on the node. The LCD provides this information but on a port
and card level also. CTC displays alarms and events on a card or node level for all
nodes in the network. You can also use TL1 to view and troubleshoot the same
alarm messages that appear in CTC.
Front Panel LEDs
The Critical, Major and Minor alarm LEDs on the fan tray front panel indicate
whether a critical, major, or minor alarm is present anywhere on the ONS 15454
assembly. These LEDs are viewable through the front door so that you can quickly
determine if any alarms are present on the assembly. These LEDs are independent
of the Slot, Status, and Port indicators on the LCD.
LCD Alarm Indicators
The ONS 15454 LCD screen provides slot and port-level information for all ONS
15454 card slots, including the number of Critical, Major, and Minor alarms.
