Power Over Ethernet (PoE) Operation for the Series 2600-PWR Switches

Viewing PoE Configuration and Status

Power Denied Cnt: Shows the number of times PDs requesting power on the port have been denied due to insufficient power available. Each occurrence generates an Event Log message.

Voltage: The total voltage, in dV, being delivered to PDs.

Power: The total power, in mW, being delivered to PDs.

Configured Type: Shows the type of PD detected on the port.

Power Class: Shows the power class of the PD detected on the indicated port. Classes include:

0: 0.44w to 12.95w

1: 0.44w to 3.84w

2: 3.84w to 6.49w

3: 6.49w to 12.95w

4:reserved

MPS Absent Cnt: This value shows the number of times a detected PD has no longer requested power from the port. Each occurrence generates an Event Log message. (“MPS” refers to the “Maintenance Power Signature”. Refer to “Terminology” on page 11-3.)

Short Cnt: Shows the number of times the switch provided insufficient current to a connected PD.

Current: The total current, in mA, being delivered to PDs.

For example, if you wanted to view the PoE status of port 5 on a Switch 2626- PWR or Switch 2650-PWR, you would use show power-management 5 to display the data:
