Table 4 describes the behavior of the Link LED - Amber, Link LED - Green, and Activity LED for
the IXF1110.
Table 4. IXF1110 LED Behavior
Type Status Description
RxLED
Off
Synchronization has occurred but no packets are being
received and the Link LED Enable Register (Addr:
0x502) is not set.
Amber On
RX Synchronization has not occurred or no optical
signal exists.
Amber Blinking
Port has remote fault and the LED Fault Disable
Register (Addr: 0x50B) is not set. Based on remote
fault bit setting received in Rx_Config word.
Green On
RX Synchronization has occurred and the Link LED
Enable Register (Addr: 0x502) bit is set.
Green Blinking
RX Synchronization has occurred and port is receiving
data.
TxLED
Off
Port is not transmitting data or the Link LED Enable
Register (Addr: 0x502)” is not set.
Green Blinking
Port is transmitting data and the Link LED Enable
Register (Addr: 0x502)” bit is set.
NOTES:
1. The LED behavior table assumes the port is enabled in the Port Enable Register (Addr: 0x500) and the
LEDs are enabled in the LED Control Register (Addr: 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.
2. For a detailed description of the LED interface and register information, refer to the IXF1110 Datasheet.
