Indicators and Buttons
Figure 4-7 Indicators on the Switch
The S220S-26PN4JX model is used as an example.
Table 4-13 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 | CLOUD | Cloud indicator | – | Off | The device is not connected to the cloud. |
| Blue | Fast blinking | The device is connecting to the cloud. | |||
| Blue | Slow blinking | The device is in the cloud management state. | |||
| 4 | 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. | |||
| 5 | 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. |
| 6 | – | 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 4-14. | |
Table 4-14 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 device provides 8 PoE ports. The maximum output power of a PoE port is 30 W, and the maximum PoE output power of the entire device is 128 W.
Heat Dissipation System
The device has no fans and uses natural heat dissipation.
