Select the Admin Mode (Enable or Disable) to determine the ability of the port to
1.
deliver power.
Port Priority is used to determine which ports can deliver power when the total power
2.
delivered by the system crosses a specific threshold. If the switch is not be able to supply
power to all connected devices, priority is used to determine which ports can supply power.
The lowest numbered port which is one of the ports of the same priority will have a higher
priority. Select the priority order from the following list:
Low - Low priority
•
Medium - Medium priority
•
High - High priority
•
Critical - Critical priority
•
Select the High Power Mode from the following options:
3.
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 powerup.
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 needs to
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 will not power up the PD.
The Power Limit Type describes or controls the maximum power that a port can deliver.
4.
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 will draw up to class 0 max power in case of low power
•
mode and up to class 4 max power in case of high power mode.
Select the Power Limit to define the maximum power (in watts) which can be delivered by
5.
a port.
