You can find the alarm status of the MMU card’s ports using the LCD screen on the ONS 15454 fan-tray
assembly. The screen displays the number and severity of alarms on a given port or slot. For the
procedure to view these counts, refer to “Manage Alarms” in the Cisco ONS 15454 DWDM Procedure
Guide.
Green ACT LED The green ACT LED indicates that the MMU card is carrying traffic or is
traffic-ready.
Amber SF LED The amber SF LED indicates a signal failure on one or more of the cards
ports. The amber SF LED also turns on when the transmit and receive fibers
are incorrectly connected. When the fibers are properly connected, the light
turns off.
