Configuration procedure
# Set the maximum power to 400 W on the card in slot 3. By default, the power of
each card is full, so the power on the card in slot 5 need not be configured.
[SW8800] poe max-power 400 slot 3
# Enable PoE on the ports GigabitEthernet3/1/1 through GigabitEthernet3/1/48.
[3Com-GigabitEthernet3/1/1] poe enable

[3Com-GigabitEthernet3/1/3] poe enable
Go on the configuration till the port GigabitEthernet3/1/48.
# Enable PoE on the ports GigabitEthernet5/1/1 through GigabitEthernet5/1/48.

Go on the configuration till the port GigabitEthernet5/1/48.
# Set the PoE priority of the port GigabitEthernet3/1/48 to critical, the PD
connected with GigabitEthernet3/1/48 will be powered in precedence on the
premise that other ports’ power supplying is not interrupted.
