How to obtain Crypto support

The following describes how to contact IBM with a comment or question about the IBM PCIe Cryptographic Coprocessor.

Note that the coprocessor is supported on the following IBM platforms: Power Systems™ running AIX®, Power Systems running IBM i, System x™, and System z™. For anything that is platform specific, contact IBM through the channel indicated on the product support page. ICSF and TKE customers should direct their inquiries through System z. For customers on Power Systems or System z, this is generally done by opening a Problem Management Record (PMR) on the IBM REmote Technical Assistance Information Network (RETAIN).

For System x customers and anything that is not platform specific, send the Crypto support team an email to . Before sending an email, please review the information provided on the product support page.

For Release 4.3, 4.2.5, and 4.1, CCA can be installed on additional operating systems by purchasing a separate add-on feature. An add-on feature is available for each of these operating systems:

With a new cryptographic hardware management solution, itcis now possible to centrally manage multiple serves with one or more cryptographic coprocessors installed. The new Crypto Hardware and Initialization Management (CHIM) solution is now available for IBM System x and IBM Power Systems.

For questions or support for any of the above add-on features, contact the IBM Crypto Competence Center at The Center is located in Denmark, which is in the Central European Time Zone (GMT+1).

The Crypto support team is located in the Eastern USA. This team monitors its email queue at least several times each business day. Normally you can expect a response within one business day.
