AOS-CX API PowerSupply and Chassis

The Device.get_subsystems() call is used to get various information about chassis, power supplies and more. This is returned in device.subsystems, a dictionary of objects where the key (name) is the subsystem type followed by a comma and an ID.

An example of chassis information looks like this:

subsystems = {
    'chassis,1': {
        'fans': {},
        'interfaces': {},
        'power_supplies': {
            '1/1': {'characteristics': {'instantaneous_power': 132, 'maximum_power': 680}, 'identity': {'airflow': 'F2B', 'description': 'Aruba X372 54VDC 680W PS', 'hardware_rev': '10', 'input_voltage_high': 240, 'input_voltage_low': 100, 'model_number': '0957-2475', 'product_name': 'JL086A', 'serial_number': 'TH33GZ9DBB', 'voltage_type': 'AC'}, 'name': '1/1', 'redundant_psu': [], 'statistics': {'failures': 0, 'warnings': 0}, 'status': 'ok'},
            '1/2': {'characteristics': {'instantaneous_power': 0, 'maximum_power': 0}, 'identity': {'description': 'N/A', 'hardware_rev': 'N/A', 'model_number': 'N/A', 'product_name': 'N/A', 'serial_number': 'N/A'}, 'name': '1/2', 'redundant_psu': [], 'statistics': {'failures': 0, 'warnings': 0}, 'status': 'fault_absent'}},
        'product_info': {

            'serial_number': 'SG37LMR0LZ',
            'vendor': 'Aruba'
        },
        'resource_utilization': {}
    },

    'chassis,10': {
        'fans': {},
        'interfaces': {},
        'power_supplies': {},
        'product_info': {
            'base_mac_address': '00:00:00:00:00:00',
            'instance': '10',
            'number_of_macs': '0',
            'part_number': '',
            'product_description': '',
            'product_name': '',
            'serial_number': '',
            'vendor': ''
        },
        'resource_utilization': {}
    },

    'chassis,2': {
        etc...

Power Supply info is stored as shown below, where the subsystem type is ‘chassis’, the id is ‘1’.
