To disable the non-standard power detection method that allows the switch to use legacy PDs, use the
following command:
disable inline-power legacy slot
PoE Operator Limits
You set the power limit that a PD can draw on the specified ports. The range is 3000 to 16800 mW, and
the default value is 15400 mW.
You set the operator limit on specified ports, which limits how much power a PD can draw from that
port by using the following command:
configure inline-power operator-limit <milliwatts> ports [all |<port_list>]
If the measured power for a specified port exceeds the port’s operator limit, the power is withdrawn
from that port and the port moves into a fault state.
To reset the power limit allowed for PDs to the default value of 15.4 W per port, use the following
command:
unconfigure inline-power operator-limit ports [all |<port_list>]
If you attempt to set an operator-limit outside the accepted range, the system returns an error message.
LEDs
Individual port LEDs on the PoE module also indicate the inline power status of each port ( Table 14 ).
Configuring PoE
PoE on the G48P module supports a full set of configuration and monitoring commands that allow you
configure, manage, and display PoE settings at the system, slot, and port level. Refer to the
ExtremeWare
XOS Command Reference Guide for complete information on using the CLI commands.
To enable inline power, or PoE, you must have a powered chassis and module.
