8. Select the High Power mode from the following options:
• Disabled indicates that a port is powered in the IEEE 802.3af mode.
• Legacy indicates that a port is powered using high-inrush current, used by legacy
PD's whose power requirements are more than 15W from power up.
• Pre-802.3at indicates a port is powered in the IEEE 802.3af mode initially and then
switched to the high-power IEEE 802.3at mode before 75 msec. This mode must be
selected if the PD is NOT performing Layer 2 Classification or the PSE is performing
2-Event Layer 1 Classification.
• 802.3at indicates that a port is powered in the IEEE 802.3at mode. For example, if the
class detected by PSE is not class4, then the PSE port does not power up the PD.
• upoe indicates that a port is powered in the UPoE mode.
9. The Power Limit Type describes or controls the maximum power that a port can deliver.
Select the type from the following list:
• Class indicates that the port power limit is equal to the class of the PD attached.
• User indicates that the port power limit is equal to the value specified by Power Limit.
• None indicates 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.
10. Select the Power Limit to define the maximum power (in watts) which can be delivered by
a port.
The maximum allowed power limit is 60000 mW per port.
11. The Detection Type Describes a PD detection mechanism performed by the PSE port.
• pre-ieee. Only legacy detection is done.
• ieee. 4 Point Resistive Detection is done.
• auto. 4 Point Resistive Detection followed by Legacy Detection is done.
• 4point and Legacy indicates that the resistive 4 point detection scheme is used and
when it fails to detect a connected PD, legacy capacitive detection is used.
12. The Timer Schedule defines the timer schedule assigned to the port. Select None to
remove the timer schedule assignment.
13. Click Reset to forcibly reset the PSE port.
14. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
The following table describes the PoE Configuration nonconfigurable fields.
Table 44. PoE Configuration
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.
