Configuring The Poe Monitoring Function; Configuring Pse Power Monitoring; Monitoring Pd - HP 5820X Switch Configuration Manual

If the guaranteed remaining PSE power (the maximum PSE power minus the power allocated to the
critical PoE interface, regardless of whether PoE is enabled for the PoE interface) is lower than the
maximum power of the PoE interface, you will fail to set the priority of the PoE interface to critical.
Otherwise, you can succeed in setting the priority to critical, and this PoE interface will preempt the
power of other PoE interfaces with a lower priority level. In the latter case, the PoE interfaces whose
power is preempted will be powered off, but their configurations will remain unchanged. When you
change the priority of a PoE interface from critical to a lower level, the PDs connecting to other PoE
interfaces will have an opportunity of being powered.
Configuration prerequisites
Enable PoE for PoE interfaces.
Configuration procedure
To configure PoE interface power management:
To do...
1. Enter system view.
2. Configure PoE interface power
management priority policy.
3. Enter PoE interface view.
4. Configure the power supply
priority for a PoE interface.

Configuring the PoE monitoring function

With the PoE monitoring function enabled, the system monitors the parameter values related to PoE power
supply, PSE, PD, and device temperature in real time. When a specific value exceeds the limited range,
the system automatically takes some measures to protect itself.

Configuring PSE power monitoring

When the PSE power exceeds or drops below the specified threshold, the system sends trap messages.
To configure a power alarm threshold for the PSE:
To do...
1. Enter system view.
2. Configure a power alarm
threshold for the PSE.

Monitoring PD

When a PSE starts or ends power supply to a PD, the system sends a trap message.
Use the command...
