Verify E-Series and ML-Series Ethernet Card LED Operation
E-Series and ML-Series card-level LEDs illuminate during a lamp test, but the port-level LEDs do not.
Note
For information about the ML-Series card, refer to the Ethernet Card Software Feature and Configuration
Note
Guide for the Cisco ONS 15454, Cisco ONS 15454 SDH, and Cisco ONS 15327.

"Verify General Card LED Operation" procedure on page 1-105
Clear port LED: Should only occur if there is a loss of receive link (such as a disconnected link or
unplugged Ethernet Gigabit Interface Converters [GBICs]). An LOS alarm could be present on the
port.
Amber port LED: Should only occur if a port is disabled but the link is connected; or if the port is
enabled and the link is connected, but a transport failure is present. A TPTFAIL alarm can be present
on the port.
Green port LED: Should occur if the port is enabled and has no errors against it or traffic in it; can
also occur if the port is enabled, has no errors, and is running traffic proportionate to the blink rate.
No traffic-affecting port alarms should be present.
"Verify General Card LED Operation" procedure on page 1-105
Clear port LED: Should only occur is there is a loss of receive link (such as a disconnected link or
unplugged GBIC), or if traffic is flowing in one direction (either transmit or receive). A CARLOSS
alarm could be present on the port.
Amber port LED: Should only occur if the link is connected and the physical port is transmitting
and receiving traffic.
Green port LED: Should occur if the link is up and no traffic is flowing on the port.
