Light emitting diodes (LEDs)
LEDs | The Device Server has LED indicators located on its front panel. The LEDs present |
| |
| shows the LEDs and a chart that explains the function of each. |
| LED | Description |
1 | Power (PWR) | Lights green when input power is good |
2 | Redundant Power (RPS) | Lights green when receiving external power from |
|
| redundant input source |
3 | Alarm (ALM) | Lights red, signaling an alarm (when an external |
|
| alarm is connected) during a down link condition on |
|
| any port, or during primary/redundant power failures |
4 | LNK/ACT | Lights green when connected to another device. |
|
| Flashes (amber) to indicate when the fiber port |
|
| receives link pulses from a compliant device (fiber |
|
| port only). |
5 | ACT | Lights to indicate when the serial port is receiving |
|
| link pulses or data from a compliant device |
6 | POST | Lights (amber) when the Power on Self Test was |
|
| successful; flashes when performing the POST |
7 | 100 | Lights (amber) to indicate when receiving data from |
|
| at 100Mbps (fiber port only) |
