Usage Guidelines
Use this command to view details about PoE power usage.
You can view the PoE operational status for the entire device, for a specific PoE
module, or for a specific interface.
The
show inline power command displays the following information.
Output field
Description
Power Capacity
The total PoE power supply capacity and the amount of available power (current free)
for PoE-power-consuming devices. Both values are shown in milliwatts.
Power Allocations
The number of times the device fulfilled PoE requests for power.
Port
The slot number and port number.
Admin State
Specifies whether Power over Ethernet has been enabled on the port:
On: The
inline power command was issued on the port.
Off: The
inline power command has not been issued on the port.
Oper State
Shows the status of inline power on the port:
On: The PoE power supply is delivering inline power to the powered device (PD).
Off: The PoE power supply is not delivering inline power to the PD.
Non-PD: Identifies the ports connected to nonpowered devices.
Denied: The port is in standby mode (waiting for power) because the device does not
currently have enough available power for the port.
Note: When you enable a port using the CLI, it may take 12 or more seconds before the operational
state of that port is displayed correctly in the
show inline power output.
Power Consumed
The number of current, actual milliwatts that the PD is consuming.
Power Allocated
The number of milliwatts allocated to the port. This value is either the default
or configured maximum power level or the power class that was automatically detected
by the device.
PD Type
The type of PD connected to the port:
802.3at: The PD connected to this port is 802.3at-compliant.
802.3af: The PD connected to this port is 802.3af-compliant.
Legacy: The PD connected to this port is a legacy product (not 802.3af-compliant).
N/A: Power over Ethernet is configured on this port, and one of the following is true:
The device connected to this port is a nonpowered device.
No device is connected to this port.
The port is in standby or denied mode (waiting for power).
Note: Although not 802.3af-compliant, some legacy products may show the PD type as 802.3af.
PD Class
Determines the maximum amount of power that a PD receives. This field can also be
"n/a" meaning that the device attached to the port cannot advertise its power class.
Note: If an 802.3at PD with a class 4 value is connected to a
RUCKUS ICX switch, the switch must be running FastIron release 08.0.20 or later to be able to
perform the necessary power negotiations.
Pri
The port inline power priority, which determines the order in which the port receives
power while in standby mode (waiting for power). Ports with a higher priority receive
power before ports with a lower priority. This value can be one of the following:
3: Low priority
2: High priority
1: Critical priority
Fault/Error
If applicable, the fault or error that occurred on the port:
critical temperature — The PoE chip temperature limit rose above the safe operating
level, thereby powering down the port.
detection failed: discharged capacitor — The port failed capacitor detection (legacy
PD detection) because of a discharged capacitor. This can occur when connecting a
non-PD on the port.
detection failed: out of range capacitor — The port failed capacitor detection (legacy
PD detection) because of an out-of-range capacitor value. This can occur when connecting
a non-PD on the port.
internal h/w fault — A hardware problem hindered port operation.
lack of power: The port shut down due to lack of power.
main supply voltage high — The voltage was higher than the maximum voltage limit,
thereby tripping the port.
main supply voltage low — The voltage was lower than the minimum voltage limit, thereby
tripping the port.
overload state — The PD consumed more power than the maximum limit configured on
the port, based on the default configuration, user configuration, or CDP configuration.
over temperature — The port temperature rose above the temperature limit, thereby
powering down the port.
PD DC fault — A succession of underload and overload states, or a PD DC/DC fault,
caused the port to shut down.
short circuit — A short circuit was detected on the port delivering power.
underload state — The PD consumed less power than the minimum limit specified in the
802.3af standard.
voltage applied from ext src — The port failed capacitor detection (legacy PD detection)
because the voltage applied to the port was from an external source.
Total
The total power in milliwatts being consumed by all PDs connected to the interface
module and the total power in milliwatts allocated to all PDs connected to the interface
module.
Grand Total
The total number of current, actual milliwatts being consumed by all PDs connected
to the PoE device and the total number of milliwatts allocated to all PDs connected
to the PoE device.
