How to configure a PoE service on the MA5626

Hello, Gerard.

You could perform the following steps to configure PoE on the MA5626:

Step 1: Run the poe power-management command to configure the power management mode (automatic or manual) of the powered device (PD) that is connected to the MA5626. The default mode is automatic.

• When a new PD with its power management mode set to automatic is connected to an MA5626 whose total power is insufficient, the MA5626 powers off all other PDs whose power management priorities are lower than the priority of the new PD, and powers on the new PD.

• When a new PD with its power management mode set to the manual is connected to an MA5626 whose total power is insufficient, the MA5626 will not power on this PD until its total power meets the requirements after the user manually shuts down other PDs.

Step 2: (Optional) Run the poe temperature-protection command to enable the overtemperature alarm function for the PoE board of the MA5626. (This command is only supported by an MA5626 that uses the H822EPUB control board.)

Step 3: Run the port command to configure the PoE port on the MA5626.

• The priority parameter takes effect only when the power management mode of a PD is set to auto using the poe power-management command. If the total power of the MA5626 is insufficient, it powers off the connected PDs according to the PDs' power supply priorities in descending order (low->high->critical).

• The mode parameter is used to configure whether the power is supplied over a signal line or an idle line. (The MA5626 only supports power supply over a signal line currently.)

• The max-power parameter is used to configure the maximum power of a port. The default power on a port is 15400 mW. When a port cannot power a PD, the display poe command can be used to query the status of this port. If the power supply status is powering off PDs according to the priorities, you can change the value of this parameter. Note that the maximum power of a port must be greater than or equal to the start power of the PD to be connected to the port. If you are not aware of the start power of the PD device, set this parameter to 30000 mW to check whether the port can power on the PD device.

A PoE service requires the following configurations: The PoE power management mode is automatic mode, the overtemperature function is enabled, the PoE function is enabled on the user port, the power transmission mode is signal line mode, the power supply priority of the user port is critical, and the maximum output power is 30 W. To configure the PoE service with the preceding parameters, do as follows:
