3com 4210 PWR 9-Port 3CR17341-91-ME 用户手册

Switch A is a Switch 4210 that supports PoE.

Ethernet 1/0/1 through Ethernet 1/0/10 of Switch A are used by users of group A, 
who have the following requirements:

■

The PoE function can be enabled on all ports in use.

■

Signal mode is used to supply power.

■

The PoE priority for Ethernet 1/0/1 through Ethernet 1/0/5 is Critical, whereas 
the PoE priority for Ethernet 1/0/6 through Ethernet 1/0/10 is High.

■

The maximum power for Ethernet 1/0/1 through Ethernet 1/0/5 ports is 3,000 
mW, whereas the maximum power for Ethernet 1/0/6 through Ethernet 1/0/10 
is 15,400 mW.

Based on the above requirements, two PoE profiles are made for users of group A.

■

Apply PoE profile 1 for Ethernet 1/0/1 through Ethernet 1/0/5;

■

Apply PoE profile 2 for Ethernet 1/0/6 through Ethernet 1/0/10.
