Measures reported by CisSGPoePSEPortTest

PoE PSE (Power Sourcing Equipment) is the ability to supply power to a device connected to a PSE-capable Ethernet port. In terms of power, a standard PoE port can support a maximum output of 15W, while a PoE+ port supports up to 30W. If the output current and voltage passing through the ports exceed the pre-configured maximum value, the port may be severely damaged and hence may cause the Cisco SG Switch to malfunction. To avoid this, it is essential to keep a constant vigil on the status of the ports available in the Cisco SG Switch as well as periodically check the output current and voltage passing through the ports. This is where the CisSGPoePSEPortTest test helps the administrators.

For each port auto-discovered on the target Cisco SG Switch, this test reports the current status. This test also reveals the output voltage, current and power passing through each port. This way, administrators can isolate the ports that are inactive and the ports on which the output voltage, output current and output power levels have exceeded the pre-configured limits.

Outputs of the test : One set of results for each port on the target Cisco SG Switch that is being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
PSEport_status Indicates the current status of this port.   The table below indicates the values that this measure can report and their corresponding numeric equivalents:

Measure Value Numeric Value
Inactive 0
Active 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current status of each port. However, in the graph of this measure, the status of the port will be represented using the corresponding numeric equivalents only.
PSEport_output_voltage Indicates the current output voltage of this port. Milli volts(mV) Compare the value of this measure across ports to identify the ports through which the output voltage is passing beyond the pre-configured limits.
PSEport_output_current Indicates the output current of this port. Milli ampere(mA) Compare the value of this measure across ports to identify the ports through which the output current is passing beyond the pre-configured limits.
PSEport_output_power Indicates the current output power of this port. Milli watts(mW) Compare the value of this measure across ports to identify the ports through which the output power is passing beyond the pre-configured limits.
