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:
