Attention: Any loss of power erases data stored in the card’s protected memory. To prevent loss,
ensure that the battery tray contains a fresh battery and is attached to the J10 connector.
7. Remove the battery attention labels from the battery holders on the card. These labels can be torn off
and discarded. They are to be replaced by the spare labels included in the kit.
8. Remove the battery in the BT1 position. To eject the battery, turn the coprocessor over and insert a
small object, such as a screwdriver, through the hole to eject the battery.
9. Replace the battery in the BT1 position with a new battery.
10. Replace the battery in the BT2 position with the battery in the battery tray. (The new battery already
installed in the BT1 position provides power to the PCI-X cryptographic coprocessor while you
perform this step.)
11. Remove the battery holder from the J10 connector.
12. Reapply the spare battery attention labels onto the holders on the card covering the batteries.
13. Re-insert the coprocessor into the PCI-X bus slot; be sure the card is fully seated.
14. Replace the host computer’s cover.
15. Reconnect the power cable and any other cables you disconnected.
16. Turn the computer ON. The PCI-X cryptographic coprocessor runs its power-on self-test (POST).
17. The batteries are lithium 3.3-volt batteries. Recycle or dispose of the old batteries as required by local
law.
You have completed the procedure for replacing the PCI-X cryptographic coprocessor batteries.
