3Com Switch 8800 Family Configuration Guide

726 CHAPTER 61: POE CONFIGURATION
■ The reserved power for a blank slot will be recycled automatically by the system
if you insert a PoE-incapable card into the slot.
■ When a card is almost fully loaded and a new PD is added, the switch will
respond to the PD according to the PoE priority set on the port.
■ The PoE priority of each port is based on its card. In other words, the switch
cannot compare the priorities of ports on different cards.
■ The sampling cycle of the power, current and voltage of ports is 1 second; the
sampling cycle of the peak power and average power of both cards and ports
is 5 minutes

Configuration
After the above-mentioned configuration, you can use the display command in
any view to view the operating state, so as to verify configuration result.

Configuration
Example
Network requirements
■ Two PoE-capable cards are installed in slots 3 and 5 on an Switch 8800 Family
series routing switch.
■ GigabitEthernet3/1/1 through GigabitEthernet3/1/48 are connected with IP
phones and GigabitEthernet5/1/1 through GigabitEthernet5/1/48 are
connected with access point (AP) devices.
■ The IP phones connected to GigabitEthernet3/1/23 and GigabitEthernet3/1/24
do not need PoE.
■ GigabitEthernet3/1/48 is reserved for the use of network management, so it
needs higher priority.
■ Slot 3 is provided with 400 W power and slot 5 is provided with full power.
■ The input power of the AP device connected to GigabitEhternet5/1/15 cannot
be greater than 9000 mW.
