Intelligent Power Management

The Intelligent Power Management (IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources.) feature actively measures the power utilization of the AP and dynamically adapts to the power resources. IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources. dynamically limits the power requirement of the AP as per the available power resources. This is in contrast to the existing static power management method where the power profiles such as POE-AF, POE-AT, POE-DC, or LLDP Link Layer Discovery Protocol. LLDP is a vendor-neutral link layer protocol in the Internet Protocol suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, which is principally a wired Ethernet. are hard-coded for each AP. The reduction steps and the associated priority values are configured to control the AP power consumption within the power budget.

The following procedure configures IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources.:

1. In the Managed Network node hierarchy, navigate to Configuration > System > Profiles tab.
2. In the All Profiles list, expand the AP menu, then select AP system.
3. Select the AP system profile that you want to edit, or click + to create a new profile.
4. Expand IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources. Configuration, and configure the following parameters:

IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources..

Configuring Reduction Steps

The reduction steps and their order are configured using either the IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources. power reduction steps with priorities parameter in the WebUI, or the ipm-power-reduction-step-prio ipm-step <reduction step> priority <priority> parameter in the ap system-profile command. The reduction steps are associated with priority values, and the priority settings are defined by integer values, where the lower values have the highest priority and are implemented first. When triggered, the reduction steps are applied sequentially starting with the reduction step that is assigned the highest priority value. The reduction steps are applied only when the AP exceeds the power budget or threshold temperature.

The following table describes the reduction steps and their corresponding WebUI and CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. parameters.
