Power Save Mode for Microbranch APs

Aruba Central now supports the Power Save feature that helps save energy consumption from common equipment in various areas like airports, offices, universities, hotels and so on. Based on the feeds, the Power Save feature dynamically enables, disables, or reduces functionality of an allocated AP to reduce consumption of energy. Once the AP fall into deep-sleep mode, the connection between the AP and Aruba Central is automatically disconnected. The APs that support the Power Save feature are also known as Green APs.

Before the APs falls into deep-sleep mode, it performs the following actions:

• Bring down all the virtual APs.
• Send a warning syslog message
• Remove all connections to managed devices.
• Set the reboot reason. This is set to ensure that when the AP wakes up from the deep-sleep mode, this reboot reason indicates that the AP has recovered from deep-sleep mode.
