3.3 Assembling / Disassembling the IR44CF II Boards
ATTENTION:
If the power connector is connected incorrectly the mainboard will be destroyed when the IR44CF II is
switched on
During reassembling, make sure the latch of the power connector fits correctly to the mainboard’s power plug.
If the ground cable coming from the rear panel is not connected to the mainboard, the mainboard can be de-
stroyed
During reassembling, make sure the ground cable is fixed correctly to the specified threaded bar of the main-
board.
PREREQUISITE:
While in the IR44CF II make sure you are aware of Electro Static Discharge (ESD), your IR44CF II power is
disconnected, and that you are properly grounding yourself.
TIP:
The complete mainboard must be replaced if the external CF card adapter is defective (e. g. locking lever
broken).
Mark all connection cables to enable a proper allocation when assembling!
This chapter describes the replacement of the IR44CF II motherboard as well as the replace-
ment of single add-on cards.
3.3.1 Preparation
Before any work on the IR44CF II device:
Disconnect all connections to the device.
Put the system on an antistatic, grounded base.
Put on an antistatic, grounded wristband.
Open the top cover as described “Removing / mounting the top cover”.
3.3.2 Removing / mounting the rear panel
The rear panel must be removed in order to replace the mainboard.
