You can save power and reduce costs by automatically disabling some of the network power consumption during non-business hours. The poesched script automatically turns power on and off to PoE ports on a specific schedule for defined locations.
Once activated, this script will be triggered once every hour, comparing the on and off configurations with the actual times of the configured locations. The PoE ports will be disabled and enabled according to the configured schedules.
