2.If a battery is installed turn off the BBU switch to disconnect the battery.

3.Remove any voice or network modules.

4.Open the CCU main cover by opening the four ‘quarter turn’ screws indicated in the first diagram below.

5.Check the fuse on the Power supply

Note: The spare fuse should only be used to replace the installed mains fuse type 3.15A T and should not be used to replace any other fuse on the power supply board.
