Configuring the
Provisioned PoE
Budget

1. From the Privilege Exec mode, enter CONFIGURE TERMINAL to
move to the Global Configuration mode:
awplus# configure terminal
awplus(config)#
2. Use the INTERFACE PORT command to move to the Port Interface
modes of ports connected to Hi-PoE or legacy PoE devices. This
example of the command moves into the Port Interface modes for
ports 9 and 10:
awplus(config)# interface port1.0.9-port1.0.10
awplus(config-if)
3. Enter the POWER-INLINE PAIR SPARE ENABLE command to
activate power on the spare strands, which corresponds to Alternative
B, on the ports:
awplus(config-if)# power-interface pair spare enable
Because Alternative A is enabled by default, the ports are now
transmitting power on all eight strands in the cables on the ports.
4. Do one of the following:
If you are configuring ports for Hi-PoE devices, no further steps are

required. The switch ports are now providing wattage to the Hi-PoE
devices on all eight strands in the cables. Go to "Configuring the
Provisioned PoE Budget" on page 104.
For ports connected to legacy PoE or PoE+ devices that only

support Alternative B, continue with the next step to disable
Alternative A.
5. Enter the NO POWER-INLINE PAIR DATA ENABLE command to
disable power on the data strands, which corresponds to Alternative A,
on the ports:
awplus(config-if)# no power-interface pair data enable
6. Go to "Configuring the Provisioned PoE Budget" on page 104.
The procedure in this section explains how to verify and adjust, if
necessary, the provisioned or nominal PoE budget for the switch. This
value is the maximum wattage the switch is expecting from the power
supply for the powered devices on its ports. The provisioned budget
should be the same as or less than the actual PoE budget from the power
supply. If the provisioned budget is above the actual budget, the switch
may experience problems. For instance, it may attempt to distribute more
power than it actually has available from the power supply or display the
PoE Status LEDs incorrectly.
