Setting the maximum power level for a PoE power- consuming device
Setting power levels configuration note
Consider the following when enabling this feature:
• There are two ways to configure the power level for a PoE or PoE+ power consuming device.
The first method is discussed in this section. The other method is provided in the section
“Setting the power class for a PoE power- consuming device” on page 672. For each PoE port,
you can configure either a maximum power level or a power class. You cannot configure both.
You can, however, configure a maximum power level on one port and a power class on another
port.
• The Brocade PoE or PoE+ device will adjust the power on a port only if there are available
power resources. If power resources are not available, the following message will display on
the console and in the Syslog:
PoE: Failed power allocation of 30000 mwatts on port 1/1/21. Will retry when
more power budget.
Configuring power levels command syntax
To configure the maximum power level for a power consuming device, enter commands such as the
following.
Brocade#configure terminal
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e1000-1/1)# inline power power-limit 14000
These commands enable inline power on interface ethernet 1 in slot 1 and set the PoE power level
to 14,000 milliwatts (14 watts).
Syntax: inline power power-limit <power level>
The <power level> variable is the maximmum power level in number of milliwatts. The following
values are supported:
• PoE – Enter a value from 1000 through 15,400. The default is 15,400.
• PoE+ – Enter a value from 1000 through 30,000. The default is 30,000.
NOTE
Do not configure a power level higher than 15,400 for standard PoE PDs, which support a maximum
of 15,400 milliwatts. Setting the power level higher than 15,400 could damage the PD.
For information about resetting the maximum power level, refer to “Resetting PoE parameters” on
page 675.
