Access Points in Thermal Management Mode

HPE Aruba NetworkingAP-555 and AP-535 access points (APs) have an internal thermal sensor. The sensor initiates a shutdown when the operating temperature crosses the temperature threshold recommended for an AP. When an AP operates in thermal management mode, all the radios are in Disabled mode in the AP Health Bar.

• In swarm mode, the thermal management mode is as follows:
  • In swarm mode, when the member AP operates beyond the recommended temperature threshold, the Virtual AP profile is disabled. After the member AP attains the optimum temperature again, it reboots with the Recovery from Thermal Management Mode message, and then reconnects with the virtual controller. This process of reboot and reconnection is executed for five times. If the connection between the member AP and the virtual controller is not restored after five times, the member AP remains in the shutdown state until it is manually turned on.
  • In swarm mode, when the conductor AP operates beyond the recommended temperature threshold, it reboots with the Reboot due to Thermal Management message. After the conductor AP attains the optimum temperature again, it turns into a member AP, reboots with the Recovery from Thermal Management Mode message, and then reconnects with the virtual controller. This process of reboot and reconnection is executed for five times. If the connection between the member AP and the virtual controller does not restore after five times, the member AP remains in the shutdown state until it is manually turned on.
  • In swarm mode, when the conductor AP operates beyond the recommended temperature threshold and the number of IAPs is one in the swarm scale, the Virtual AP profile is disabled. After the conductor AP attains the optimum temperature again, it reboots with the Recovery from Thermal Management Mode message. This process of reboot is executed for five times. If the conductor AP does not reboot after five times, the conductor AP remains in the shutdown state until it is manually turned on.
• In standalone mode, when the AP operates beyond the recommended temperature threshold, the Virtual AP profile is disabled. After the AP attains the optimum temperature again, it reboots with the Recovery from Thermal Management Mode message. This process of reboot is executed for five times. If the AP does not reboot after five times, it remains in the shutdown state until it is manually turned on.

When the thermal management mode is either enabled or disabled in an AP, the Events table displays the following details:

• The Event Type column includes the AP Thermal Shutdown type which can be used to filter thermal shutdown events.
• The Description column includes the status of the thermal shutdown feature in the AP. For example, Thermal management enabled or Thermal management disabled.
