The battery is a lithium battery. To avoid possible explosion, do not burn or
charge the battery. Exchange only with the IBM-approved part. Discard the
battery as instructed by local regulations. (RSFTC227)
1. Remove the 4758 PCI Cryptographic Coprocessor card from the system (see
“Models 830/SB2 with FC 9074 – Cards – Concurrent” on page 655, “Models
840/SB3, FC 8079 (lower half), FC 9079 Cards — Concurrent” on page 678,
“FC 5074, FC 5079 – Cards – Concurrent” on page 620, or “FC 5075 – Cards –
Concurrent” on page 638).
2. Find the location of the 4 lithium batteries. They are located in adjacent
holders, with the Battery 2 holder above the J3 connector. Refer to the
illustration below.
Note: The 4758-023 card contains 4 batteries, even though only 2 batteries are
shown in the figure above. Battery 3 is next to Battery 1, and Battery 4
is next to Battery 2.
3. Attention: Any loss of battery power erases data stored in the card’s
protected memory and renders the card useless.
4. Open both of the battery replacement kits.
5. Insert one of the new batteries into the battery tray provided with the kit.
Note: The battery ’+’ must be oriented in the battery tray with the same
polarity matching the ’+’ on the tray.
6.
Connect the battery tray’s cable to the J3 connector on the 4758 card.
Note: This maintains battery power to the card while the new batteries are
installed one at a time. Refer to step 3 of this procedure.
7. Remove the 2 battery warning labels which cover both sets of batteries..
Discard the labels.
8. Replace the battery in the Battery 1, 2 and 3 positions with a new battery.
Note: The battery ’+’ must be oriented in the holder with the same polarity
matching the ’+’ on the holder.
9.
Replace the battery in the Battery 4 position with the battery in the battery
tray.
Note: The battery ’+’ must be oriented in the holder with the same polarity
matching the ’+’ on the holder.
10. Remove the battery tray from the J3 connector and discard it.
