Indicators and Buttons
Table 4-30 Description of indicators on the switch
| No. | Indicator | Name | Color | Status | Description |
|---|---|---|---|---|---|
| 1 | PWR | Power module indicator | – | Off | The switch is powered off. |
| Green | Steady on | The power supply is normal. | |||
| 2 | SYS | System status indicator | – | Off | The system is not running. |
| Green | Fast blinking | The system is starting. | |||
| Green | Steady on | During the system startup preparation phase, the SYS indicator is steady green, which lasts for a maximum of 30 seconds. | |||
| Green | Slow blinking | The system is running normally. | |||
| Red | Steady on | The system does not work normally after registration, or a fan alarm or a temperature alarm has been generated. | |||
| 3 | PoE | PoE indicator | – | Off | The PoE mode is not selected. |
| Green | Steady on | The PoE mode is selected, and service port indicators show the PoE status of each port. | |||
| 4 | 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. |
| 5 | – | Service port indicator (one indicator for each port) | Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top. | Meanings of service port indicators vary in different modes. For details, see Table 4-31.
NOTE: If a power failure occurs on a device’s PCB board, indicators of the last four GE or 10GE 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 | CLOUD | Cloud indicator | – | Off | The device is not in the cloud management state. |
| Blue | Fast blinking | The device is connecting to the cloud. | |||
| Blue | Slow blinking | The device is in the cloud management state. | |||
Table 4-31 Description of service port indicators in different modes (one indicator for each port)
| 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. The built-in power module can provide 400 W PoE power, which ensures full PoE power on 24 ports in compliance with 802.3af or on 13 ports in compliance with 802.3at.
Heat Dissipation System
The switch has two built-in fans for forced air cooling. Air flows in from the left side and front panel, 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.
