MDA LED indications
Label Color State Meaning
Green Steady Indicates network activity for the corresponding port.
A very low level of network activity (approximately
1–5 pps) can cause the LED to blink.
— Off The port is not transmitting data (no network activity).
TX
Amber Blinking The port is out of order; the administrative state is
down.
Green Blinking Indicates network activity for the corresponding port
(the port is receiving traffic).
Green Steady The port is operational; no network activity.
Amber Blinking The port is not operational; the administrative state
is down.
Amber Steady
A Remote Defect Indication (RDI) alarm condition
has been detected; the administrative state is down.
The RDI alarm condition indicates that a failure
occurred at the far end of the network. In ATM,
when the physical layer detects loss of signal or
cell synchronization, RDI cells are used to report a
VPC/VCC failure. RDI cells are sent upstream by a
VPC/VCC endpoint to notify the source VPC/VCC
endpoint of the downstream failure.
RX
— Off The port is not operational. Be sure that the MDA is
fully seated in the slot; check that the port is properly
configured.
