PoE Configuration
Example
Networking requirements
■ Two PoE-enabled boards are installed in slot 3 and 5 on a Switch 7757.
■ Online upgrade the PSE processing software of the PoE board in slot 5 of the
Switch 7757.
■ Ethernet3/0/1 to Ethernet3/0/48 are connected with IP phones and
Ethernet5/0/1 to Ethernet5/0/48 are connected with access point (AP) devices.
■ The IP phones are connected to Ethernet3/0/1 through Ethernet3/0/48, and
access point (AP) devices are connected to Ethernet5/0/1 through
Ethernet5/0/48.
■ PoE need not be enabled on the IP phones connected to Ethernet3/0/1 and
Ethernet3/0/48.
■ Ethernet3/0/48 requires high priority.
■ Set the PoE management mode of slot 3 to auto.
■ Slot 3 is supplied with 400 W of power and slot 5 is supplied with full power
(namely, 806 W).
■ Enable PoE-compatibility detection on the PoE board in slot 3.
■ The input power of the AP device connected the Ehternet5/0/15 port cannot
be greater than 9 W.
