5.3.4 z990 cryptographic feature codes
What follows is a list of the cryptographic features available with the z990.
Feature code Description
3863 Crypto enablement
Crypto enablement feature. Prerequisite to use the CPACF, PCIXCC, and
PCICA hardware features.
0868 PCIX Cryptographic Coprocessor (PCIXCC) feature
0862 PCI Cryptographic Accelerator (PCICA) feature
0886 TKE hardware for Token Ring
TKE workstation hardware with Token Ring connection, DVD drive, and
17-inch monitor.
0851 TKE 4.0 code
0852 TKE 4.1 code (available May 2004)
0889 TKE hardware for Ethernet
TKE workstation hardware with Token Ring connection, DVD drive, and
17-inch monitor.
0851 TKE 4.0 code
0852 TKE 4.1 code (available May 2004)
The z990 requires TKE Version 4.0 or 4.1 code. In case a z900 with a TKE 3.x workstation is
upgraded to a z990, the TKE Version 3.x workstations can be retained to control other
servers, but cannot be used on the z990. To control the z990, TKE Version 4.0 or 4.1 code is
required. TKE 3.x workstations that are carried forward are automatically updated to the 4.1
TKE code when a PCIXCC feature is ordered or present on the sever.
The TKE Version 4.0 or 4.1 code supports all models back to CCF support on a G3 CMOS
processor.
TKE 4.1 code provides local and a remote key entry with a master key.

Note: The z990 (and the z890) are the last zSeries servers offering Token Ring adapters
on the Trusted Key Entry (TKE) workstations. Timely planning is advised to prepare for
migration to the Ethernet environment.
