Power Detect Type
The PD detection mechanism performed by the PSE port. Possible value are:
Dot3af/at—The 4-point detection scheme defined in IEEE 802.3af is used. This is the
default option.
Dot3af/at + Pre-Standard—The 4-point detection scheme defined in IEEE 802.3af is
used. If this mechanism fails to detect a connected PD, Dot3af/at detection is used.
Power Limit Type
The type of power limiting used for the port. Possible values are:
Class—The device class determines the power limit. The switch learns the class of the
device through the receipt of LLDP messages. This is the default selection.
User—The power limit is user-defined, overriding the LLDP information.
When set to User, the specified power limit also displays next to this value. When High Power
Mode is enabled, the maximum value is 30W. When High Power Mode is disabled, the
maximum value is 15.4W. (The Power Limit field is available on the Edit PoE Port
Configuration page.)
Status
The status of the port as a provider of power over Ethernet. Such devices are referred to as
power-sourcing equipment (PSE). Possible values are:
Disabled—The PSE is disabled.
Delivering Power—The PSE is delivering power.
Fault—The PSE has experienced a fault condition.
Test—The PSE is in test mode.
Other Fault—The PSE has experienced a variable error condition.
Searching—The PSE is transitioning between states.
Requesting Power—The PSE is currently not able to deliver power because power is
unavailable to the port.
Fault Status
The fault status, if a fault occurred. Possible values are:
None—No faults have occurred.
Short—The switch provided insufficient current to a connected PD
Overload—A connected PD has attempted to draw more than the allowed watts.
Power Denied—A PD requesting power on the port has been denied because of insuffi-
cient power available.
