LED matrix on the Express hub
Type | Label | Color | Meaning |
Hub power supply status | Pwr | Green | Hub is receiving AC power. |
|
| Off | Hub is not receiving AC power. |
|
|
|
|
Hub status | Stat | Green | Hub is powered, has passed the confidence test, and |
|
|
| is operating normally. |
|
| Amber | At initial power up, this LED lights to indicate the |
|
|
| hub is running its confidence test. If this LED lights |
|
|
| after the confidence test is performed, it indicates the |
|
|
| hub is not operating normally due to a fan failure, a |
|
|
| hub power supply failure, or a confidence test failure. |
|
| Off | Hub is not receiving power. |

|
Network utilization | Data % | Blinking | The ≤1% LED blinks green to indicate there is traffic |
|
| green | on the segment that is utilizing less than 1% of the |
|
|
| network. |
|
| Solid green | The Data % LEDs light solid green to indicate the |
|
|
| percentage of the network utilization for the Ethernet |
|
|
| segment in a standalone hub or a stack of hubs. These |
|
|
| LEDs operate as a bar graph to provide you with a |
|
|
| continuous indication of the network utilization. For |
|
|
| example, if the 1% and 5% Data LED light green, the |
|
|
| Ethernet segment in that stack of hubs is utilizing 5% |
|
|
| of the network. |
