| LED | Status | Condition |
|-------+-----------+----------------------------------------|
| LED1 | Blinking | Card is transmitting for an extended |
| | | time (Jabber) |
|-------+-----------+----------------------------------------|
| LED1 | On | Normal operation |
|-------+-----------+----------------------------------------|
| LED2 | Blinking | Collision detected on network |
|-------+-----------+----------------------------------------|
| LED2 | On | Normal operation |
|-------+-----------+----------------------------------------|
| LED3 | Blinking | Data is being received |
|-------+-----------+----------------------------------------|
| LED3 | On | Data is not being received/Twisted |
| | | pair network connection good |
|-------+-----------+----------------------------------------|
| LED3 | Off | Twisted pair network connection broken |
|-------+-----------+----------------------------------------|
| LED4 | Blinking | Data is being transmitted |
|-------+-----------+----------------------------------------|
| LED4 | Off | Data is not being transmitted |
|------------------------------------------------------------|
| Note: The function of LED3 is dependent on the cable type |
| selected. |
| |
| LED3 will indicate twisted pair network connection only |
| when the cable type is twisted pair. |
