Once the unit is reassembled, these zipties must be replaced. Failure to do this will result in protection mode errors.

Cut the zipties that hold the front panel wires on the fan. This provides better component access.

With the faceplate loose and all of the cables disconnected, unclip the faceplate one side at a time. Lay the faceplate flat on your workspace. Leave enough room to access the boards on the front panel.
