zSeries 800: Installation Manual for Physical Planning
zSeries 800s may have a cryptographic coprocessor feature for applications where
extensive data security is required. For these systems, there is a separate console
available for authorized access to the cryptographic feature. This console is named
the Trusted Key Entry (TKE) PC.
The TKE workstation includes a system unit, mouse, keyboard, monitor, and line
cord. A DVD is available for installation of Licensed Internal Code.
Note: zSeries 890 and 990 are the last zSeries servers that will support Token
Ring LAN connection to the TKE workstation.
TKE workstation LAN adapter feature codes depend on the version of the TKE
microcode.
Table 4-1.
TKE Microcode Level
3.0
3.1
4.0
4.1
Notes:
1. Older levels of LAN connection Feature Codes can be carried forward on
system upgrades.
2. FC 0886 and FC 0889 are only orderable with zSeries 990.
3. zSeries 990 and zSeries 890 require TKE microcode levels at either 4.0 or 4.1.
The Token Ring adapter supports a link data rate of 4 or 16 Mbps. Ethernet on the
system unit motherboard supports a link data rate of 10, 100, or 1000 Mbps. The
Ethernet adapter supports a link data rate of 10 or 100 Mbps.
The TKE workstation attaches to the customer LAN, providing a security-rich,
flexible method of providing master key and operational key entry to locally and
remotely managed Cryptographic Coprocessor features.
Customers with TKE 3.x installed workstations may carry them forward to control
legacy systems only.
To use the TKE function on zSeries 800, the CMOS Cryptographic Coprocessor
Facility(CCF) feature must be enabled and the PCICC feature (FC 0861) must be
installed. An update from TKE 3.0 or TKE 3.1 microcode level to TKE 4.0 or TKE
4.1 microcode level is required for use with the zSeries 890.
The TKE PC requires two 110/120 volt outlets in the U.S. and Canada. Power
requirements vary in other countries.
LAN cabling is a customer responsibility.
To connect the TKE workstation with Token Ring to a LAN, use either
v Unshield Twisted Pair (UTP) cable terminated with an RJ-45 connector
