Chapter 3. Replacing IBM PCI-X cryptographic coprocessor
batteries
This section describes the way to replace the batteries on the IBM 4764-001 PCI-X Cryptographic
Coprocessor.
Two lithium batteries mounted on the IBM 4764-001 PCI-X Cryptographic Coprocessor supply power to the
card’s components, including protected memory. Your support software or application software can query
the coprocessor to determine whether the batteries need to be replaced.
When shipped from the factory, the protected memory contains a certified device key. If your coprocessor
has been initialized by support software, the protected memory contains secret data, including a master
cryptographic key, user profiles, and user passwords.
Attention: If you remove either of the batteries without first backing up the power with a fresh battery, the
data in protected memory can be lost. The Replacement Battery Kit for the IBM 4764 PCI-X Cryptographic
Coprocessor (Feature #1008) provides the battery tray needed to provide backup power while you replace
the batteries.
To order the kit, contact your local IBM representative or your IBM Business Partner.
