(3) Link/Activity Status LEDs
The first (top) and third row of LEDs, which are colored yellow or green, show the link, activity and speed status of the related ports:
10/100/1000BASE-T Ports
Status | Meaning | |
|
| |
Green | The link is operating at 1000 Mbps. | |
Yellow | The link is operating at 10 or 100 Mbps. | |
Flashing | Packets are being received or transmitted on the | |

Flashing | Packets are being received or transmitted on the | |
Yellow | port at 10 or 100 Mbps. | |
Off | The link has not been established, either nothing | |
| is connected to the port, or there is a problem: | |
| ■ | Check that the attached device is powered |
|
| on. |
| ■ | Check that the cable or fiber is the correct |
|
| type and is not faulty. |
| ■ | For fiber connections, ensure that the receive |
