Order 4765 battery-replacement kit

The IBM PCIe Cryptographic Coprocessor Version 1 (PCIeCC) is supported as IBM Z® features CEX4S and CEX3C, machine type-model (MTM) 4765-001, and IBM Power Systems™ features EJ27, EJ28, and EJ29.

PCIeCC withdrawn from marketing

As of October 31, 2016, IBM® withdrew from marketing the MTM 4765-001. See Hardware Withdrawal: IBM Cryptographic Coprocessor for more information. The replacement cryptographic coprocessor is the IBM 4767-002. See IBM PCIeCC2 Overview for information.

MTM 4765-001 end of support

As of December 31, 2018, IBM plans to end support for the MTM 4765-001 on x86 servers.

The PCIeCC is currently supported on IBM Z (zEC12, z196 and z10® only), either on z/OS® or Linux® on IBM Z operating systems. It is ordered as a Crypto feature code (FC). It is also supported on select IBM-approved x86 servers as an IBM Z machine type-model (MTM), on certain SUSE® (a Micro Focus Company) Linux Enterprise Server (SLES) operating systems, and on IBM Power Systems™ (either IBM AIX® or IBM i) as a Crypto feature code (FC).

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 the Part number information below.

4767 battery tray

Part number for 4765 battery replacement kit

Part number Description
FRU 45D5803 Battery-replacement kit. Includes two replacement batteries, one battery-attention label, and one battery tray with connecting wires.


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.
