How to place an order for a 4765 battery-replacement kit
The 4765 has two on-board batteries which provide critical backup power to a small quantity of internal memory, the clock-calendar, and the tamper-detection circuitry. So that you can maintain the functionality of the coprocessor, a kit containing
replacement batteries for the 4765 is available through IBM as a field replaceable unit (FRU). Refer to Table 2.

Note: Part number 45D5803 can also be used for 4767 battery replacement.
Important: It is imperative that the coprocessor always has batteries installed with sufficient stored energy to power the coprocessor during its entire useful life. When the coprocessor is not in a powered-on system and the
batteries either fail or are removed from the coprocessor, the unit will zeroize and be rendered permanently inoperable. There is no recovery from this situation.
Special procedures are required to safely replace coprocessor batteries. Instructions for replacing the batteries are in IBM 4765 PCIe Cryptographic Coprocessor Installation Manual. This manual is available for download from the Library page.
