Network Interface Card LEDs
The network card features two I/O LEDs per port:
- LED 1 and 2 are bi-color I/O LED which indicate link status. LED behavior is described below for Ethernet and InfiniBand port configurations.
- LED 3 and 4 are reserved for future use
Ethernet Network Port LED Behavior
| LED Color and State | Description |
|---|---|
| Off | No link is established |
| Blinking amber | 1Hz blinking amber occurs due to running a beacon command to locate the adapter card 4Hz blinking amber indicates a problem with the physical link |
| Solid green | Indicates a valid link with no active traffic |
| Blinking green | Indicates a valid logical link with active traffic |
InfiniBand Network Port LED Behavior
| LED Color and State | Description |
|---|---|
| Off | No link is established |
| Solid amber | Indicates an active physical link |
| Blinking amber | 1Hz blinking amber occurs due to running a beacon command to locate the adapter card 4Hz blinking amber indicates a problem with the physical link |
| Solid green | Indicates a valid link with no active traffic |
| Blinking green | Indicates a valid logical link with active traffic |
