MODE |
Mode switch button |
- |
- |
If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the PoE indicator is off. |

- |
Service port indicator |
Meanings of service port indicators vary in different modes. For details, see Table 4-81. NOTE:
If a power failure occurs on a device's PCB board, indicators of the last four optical ports on the device's front panel blink green cyclically at an interval of 1 second, with each indicator illuminating for 0.25 seconds. |

6 |
ID |
ID indicator |
- |
Off |
The ID indicator is not used (default state). |
Blue |
Steady on |
The indicator identifies the switch to maintain. The ID indicator can be turned on or off remotely to help field engineers find the switch to maintain. |

Display Mode |
Color |
Status |
Description |
|---|---|---|---|
Default mode |
- |
Off |
The port is not connected or has been shut down. |
Green |
Steady on |
A link has been established on the port. |
|
Green |
Blinking |
The port is sending or receiving data. |
|
PoE mode |
- |
Off |
The port is not providing power to a powered device (PD). |
Green |
Steady on |
The port is providing power to a PD. |
|
Green |
Blinking |
The power of the PD connected to the port exceeds the power capacity of the port or the power threshold configured on the port. Alternatively, the PD does not comply with IEEE standards. |
Power Supply System
The switch has a built-in AC power module and does not support pluggable power modules.
Heat Dissipation System
The switch has a built-in fan for forced air cooling. Air flows in from the left side, and exhausts from the right side.
When working properly at a normal temperature, the device meets the desktop-class noise requirements. However, the fan speed may be high and the noise may be loud during device startup.
This figure only shows the airflow direction and does not depict the actual device.
