Intelligent Power and Temperature Monitoring

The Intelligent Power and Temperature Monitoring feature is an enhancement to the existing IPMIntelligent 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 of Instant APs. IPTM is the combination of both IPMIntelligent 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. and ITM functions for enhanced optimization of AP operations in changing power and temperature conditions.

In order to manage this optimization, a set of reduction steps can be configured and associated with a priority value. IPTM applies a sequence of reduction steps as defined by the priority definition until the AP is functioning within the power budget and threshold temperature. This happens dynamically as IPTM constantly monitors the power consumption and temperature of the AP.

IPMIntelligent 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. and ITM must be enabled separately using the CLICommand-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.. However, the reduction steps applied for IPMIntelligent 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. and ITM are the same and are configured under ipm command. The IPMIntelligent 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. and ITM settings configured for the AP can be viewed using the show running configuration command.

Important Points to Remember

Intelligent Power Management

IPMIntelligent 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.  measures the power utilization of the AP and dynamically adapts to the power budget. IPMIntelligent 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, PoEPower over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port.-DC, or LLDPLink 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 following CLICommand-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. command enables IPMIntelligent 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.:

(Instant AP)(ipm)# enable

Reporting Power Values to Central

Instant APs can measure and periodically report their power information such as current, average, minimum, and maximum power consumption values sampled over the previous one minute and report the same to Aruba Central. When Instant APs measure the power values, they send the information to the master Instant AP over a PAPIProcess Application Programming Interface. PAPI controls channels for ARM and Wireless Intrusion Detection System (WIDS) communication to the master controller. A separate PAPI control channel connects to the local controller where the SSID tunnels terminate. message. This information is saved and finally sent to Central.

This functionality is supported on IAP-334, IAP-335, IAP-314, IAP-315, IAP-304, IAP-305, AP-303H, AP-344, AP-345, AP-374, AP-375, AP-377, AP-318 access points.

The following CLICommand-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. command is used to view the power monitoring information:

(Instant AP) #show aps power-monitor

Intelligent Thermal Management

ITM measures the internal temperature of the AP and dynamically adapts operations to reduce the internal temperature. When enabled, the operations of the AP will be throttled down when the internal temperature exceeds the maximum threshold. The reduction steps applied to control the temperature are defined using the ipm-power-reduction-step-prio ipm-step parameter in the ipm command.

The following CLICommand-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. command enables ITM:

(Instant AP)(config)# itm

Configuring Reduction Steps

The priority for reduction steps are configured using the ipm-power-reduction-step-prio ipm-step parameter in the ipm command. The priority values range from 1-16, 1 being the highest and 16 being the lowest. The reduction steps are applied sequentially, starting with the reduction step assigned the highest priority value. The reduction steps will be applied only if the AP exceeds the power budget or threshold temperature when IPMIntelligent 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. or ITM is enabled.

Setting a high-priority value to a maximum reduction step like cpuCentral Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions._throttle_75 reduces the power and temperature level sooner than a minimum or medium reduction step like cpuCentral Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions._throttle_25 or cpuCentral Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions._throttle_50. However, if the reduction step is of the same type but a different level, the smallest reduction should be allocated a higher priority value so that the reduction step takes place earlier. For example, the cpu_throttle_25 or radio_2ghz_power_3dB parameter should have a higher priority level than cpu_throttle_50 or radio_2ghz_power_6dB, respectively, so that IPMIntelligent 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. reduces the CPUCentral Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. throttle or power gradually based on the priority list.
