98 Summit 300-48 Switch Software User Guide
Power Over Ethernet
Ports are powered based upon their priority and discovery time. Higher priority ports with the oldest
discovery time are powered first.
If a device consumes more power than it is allocated by class type, it is considered a class violation. The
device enters a fault state, and unreserved power is returned to the common pool. Power is also
returned to the common pool if a port is disconnected. The device stays in the fault state until you
explicitly clear the fault, disable the port for power, or disconnect the device.
Per-Port LEDs
The per-port LEDs indicate link and power status for PoE usage, as indicated in Table 35:
NOTE
Wait for the LED to extinguish before reconnecting to the port.
Configuring Power Over Ethernet
Use the inline power commands in Table 36 to configure PoE on Summit 300-48 switch ports.
NOTE
Configuration parameters affecting operational parameters require the port or slot to be first disabled.
