Type Status Description
RXLED
Off
Synchronization occurs but no packets are received
and the “Link LED Enable ($0x502)” is not set.
Amber On
RX Synchronization has not occurred or no optical
signal exists.
Amber Blinking
The port has remote fault and the “Link LED Enable
($0x502)” is not set (based on remote fault bit setting
received in Rx_Config word).
Green On
RX Synchronization occurs and the “Link LED Enable
($0x502)” bit is set.
Green Blinking
RX Synchronization occurs and the port is receiving
data.
TXLED
Off
The port is not transmitting data or the “Link LED
Enable ($0x502)” is not set.
Green Blinking
The port is transmitting data and the “Link LED Enable
($0x502)” bit is set
NOTE: Table 35 assumes the port is enabled in the “Port Enable ($0x500)” and the LEDs are enabled in the
“LED Control ($0x509)”. If a port is not enabled, all the LEDs for that port will be off. If the LEDs are not
enabled, all of the LEDs will be off.
