• Legacy. Specifies that the port is powered using a high-inrush current, used by
legacy PDs for which startup power requirements exceed 15W.
• Pre-802.3at. Specifies that the port is powered in the IEEE 802.3af mode initially and
then switched to the high-power IEEE 802.3at mode within a period of 75 msec.
This
mode must be selected if the PD does not perform Layer 2 classification or if the
switch performs 2-event Layer 1 classification.
• 802.3at. Specifies that the port is powered in the IEEE 802.3at mode.
9. From the Power Limit T
ype menu, select the maximum power that a port can deliver.
Select one of the following options from the menu:
• None. Specifies that the port draws up to class 0 maximum power in low-power mode
and up to class 4 maximum power in high-power mode.
• Class. Specifies that the port power limit is equal to the class of the attached PD.
• User. Specifies that the port power limit is equal to the value specified in the Power
Limit field.
10. In the Power Limit (W) field, specify the maximum power in watts that a port can deliver
.
The maximum allowed power is 30W per port.
11. From the Detection T
ype menu, select how the port detects the PD:
• pre-ieee.
The port performs legacy detection.
• IEEE 802.
The port performs a 4-point resistive detection. This is the default setting.
• auto.
The port performs a 4-point resistive detection, and if required, continues with
legacy detection.
12. From the T
imer Schedule menu, select a timer schedule that just be assigned to the port.
By default, the selection is None, which specifies that no timer schedule is assigned to
the port. For more information about timer schedules, see
Manage Timer Schedules on
page 160.
13. Click the Apply button.
Your settings are saved.
14. T
o reset the selected ports, click the Reset button.
The ports are reset.

Field Description
Port The interface for which data is to be displayed or configured.
High Power Enabled when particular port supports High Power mode.
Max Power The maximum power in Watts that can be provided by the port.
