PoE Port Configuration
Use the PoE Port Configuration page to configure per-port PoE settings.
To display this page, click System
PoE Advanced PoE Port Configuration. A screen
similar to the following displays.
1. Unit - Displays the Current PoE Unit. You can change the PoE Unit by selecting another
unit ID listed here.
2. Use Admin Mode to enable/disable the ability of the port to deliver a power.
3. Use Port Priority to determine which ports can deliver power when total power delivered by
the system crosses a certain threshold. The switch may not be able to supply a power to all
connected devices. Priority is used to determine which ports can supply power. The lower
numbered port which is one of the ports of the same priority will have a higher priority.
• low - Low priority.
• high - High priority.
• critical - Critical priority.
4. Use High Power Mode to specify one of the following:
• Disable value means that a port is powered in the IEEE 802.3af mode.
• Legacy value means that a port is powered using high-inrush current, used by legacy
PDs whose power requirement is more than 15W from powerup.
• Pre-802.3at value means that a port is powered in the IEEE 802.3af mode initially,
switched to the high-power IEEE 802.3at mode before 75msec. This mode needs to
be used, if PD is NOT performing Layer 2 Classification Or PSE is performing 2-Event
Layer 1 Classification.
• 802.3at value means that a port is powered in the IEEE 802.3at mode, i.e., if class
detected by PSE is not the class4, then the PSE port will not power up the PD.
