• The motherboard that you use as a spare part does not include the key chip. The Keychip contains the license information of the E-24B controller and the activated optional features, which is very expensive. When you replace the motherboard, do not forget to move the key chip from the old board to the new board.

You need to re-configure the system date, time, and time zone. [Link to Adjusting the System Date and Time]

  7. Remove the Keychip [A].
  8. Remove the CPU holder bracket (on the back side of the motherboard) [A]
    The CPU holder bracket is attached to the motherboard with two strips of double-sided tape. In order to prevent the motherboard from being damaged, put a small screwdriver between the bracket and the motherboard as shown below and twist the screwdriver to detach the CPU holder bracket.

  • When you replace the motherboard, move the CPU, CPU cooling assembly, video board, Keychip, and the CPU holder bracket from the old board to the new board. The Keychip contains option upgrade information and licensing information for the E-24B.
  • A new motherboard comes with a protective cover [A] on the CPU slot. Remove it before using the motherboard.

For reassembling:

  • Make sure of where to connect the connectors for each cable.
  • Make sure that all connectors are inserted firmly in the sockets. Also, do not put the connectors in the sockets the wrong way around.
