Setting the Jumper

1 Open the Sunny Mini Central as described in section 10.2 "Opening of the

Sunny Mini Central" (Page 59).

2 Place the jumper on the controller board socket, as laid out below.

3 Close the Sunny Mini Central as described in section 10.3 "Closing of the

Sunny Mini Central" (Page 60).

4 The Sunny Mini Central recognizes the jumper only after the system has been

restarted (i.e. all LEDs must have gone out before a restart).

5 Check the fans' air-flow. The Sunny Mini Central sucks air in from underneath

and then blows it back out on the upper sides. Listen for any unusual noise,

which could indicate incorrect installation or that the fans are faulty.

6 Once you have checked the fans, remove the jumper.

Open and close the Sunny Mini Central as described in section 10 "Opening

and Closing the Sunny Mini Central" (Page 58).
