108 IBM ^ zSeries 990 Technical Guide

The port cards support concurrent maintenance. The ETR card port has a small form factor

optical transceiver that supports an MT-RJ connector only.

3.4.7 Cryptographic features

What follows are the cryptographic features available on z990 servers. To enable any

cryptographic function on the z990, the CP Assist for Cryptographic Function (feature code

3863) must be installed and enabled. For more information about cryptographic functions,

see Chapter 5, “Cryptography” on page 119.

PCIX Cryptographic Coprocessor (PCIXCC) feature

The Peripheral Component Interconnect X Cryptographic Coprocessor (PCIXCC) feature

(feature code 0868) occupies one I/O slot in the z990 I/O cage.

Each PCIXCC feature has one coprocessor. It does not require a CHPID number, but is

assigned to a PCHID.

The CP Assist for Cryptographic Function (feature code 3863) must be installed and enabled

to use PCIXCC.

PCI Cryptographic Accelerator (PCICA) feature

The Peripheral Component Interconnect Cryptographic Accelerator (PCICA) feature (feature

code 0862) occupies one I/O slot in the z990 I/O cage.

Each PCICA feature has two accelerator cards. The PCICA feature does not require CHPID

numbers, but is assigned to PCHIDs.

The CP Assist for Cryptographic Function (feature code 3863) must be enabled to use

PCICA.

Important: The z990 timer support has been enhanced and requires a customer to assign

a timer netID that must match the Sysplex Timer (9037) netID before the CPC clock will

step to the 9037 time signals; refer to 7.2.1, “Sysplex configurations and Sysplex Timer

considerations” on page 159 for more information.

Note: The ETR card does not support a multimode fiber optic cable terminated with an

ESCON Duplex connector.

However, 62.5 micron multimode ESCON Duplex jumper cables can be reused to

connect to the ETR card. This is done by installing an MT-RJ/ESCON Conversion kit

between the ETR card MT-RJ port and the ESCON Duplex jumper cable.

Fiber optic conversion kits and Mode Conditioning Patch (MCP) cables are not orderable

as features on z990. Fiber optic cables, cable planning, labeling, and installation are all

customer responsibilities for new z990 installations and upgrades.

IBM Fiber Cabling Services offer a total cable solution service to help with your cable

ordering needs, and is highly recommended.
