If not created already, create an instance of Rest or Redfish Object using the RestObject or RedfishObject class respectively. The class constructor takes iLO hostname/ ip address, iLO login username and password as arguments. The class also initializes a login session, gets systems resources and message registries.

Rest Object creation:

REST_OBJ = RestObject(iLO_host, login_account, login_password)

:

Redfish Object creation:

REDFISH_OBJ = RedfishObject(iLO_host, login_account, login_password)

:

The method ex15_set_uid_light takes an instance of rest object (or redfish object if using Redfish API) and boolean uid state (FALSE for turn off or TRUE for turn on) as arguments.

def ex15_set_uid_light(restobj, uid):

:

Find and get the system resource for computer system.

instances = restobj.search_for_type("ComputerSystem.")

:

Prepare the PATCH request header based on the requested UID state parameter.

for instance in instances:
   body = dict()
   if uid:
     body["IndicatorLED"] = "Lit"
   else:
     body["IndicatorLED"] = "Off"

:

Perform the PATCH action, check the response.

response = restobj.rest_patch(instance["href"], body)
restobj.error_handler(response)
