3. If you are replacing the motherboard with a new motherboard, remove the following from the old motherboard:
• DIMM ("DIMM" on page
• CPU ("CPU and CPU cooling assembly" on page
• Security chip (see next section)
Transferring the security chip
Transferring the security chip from the old motherboard to the new motherboard ensures that all customer-purchased software
options are transferred.
IMPORTANT:
Make sure to remove the security chip from the old motherboard before returning the old motherboard to your authorized
service/support center. If you fail to install the security chip on the new motherboard, the imagePASS will not start up and
all customer-purchased software options will be lost.
To transfer the security chip to the new motherboard
1. Locate the extraction tool provided in the new motherboard kit.
2. Remove the security chip from socket J12(CRYPTO) on the old motherboard
Carefully position the extraction tool around the edges of the security chip, and pull the chip straight out of the socket. Make
sure not to put stress on surrounding components.
IMPORTANT:
Do not rock the chip from side to side when removing it from the socket. Doing so may result in permanent damage to the
security chip.
3. Inspect the security chip and carefully straighten any bent pins with needlenose pliers.
