Owner`s manual

You will need to upgrade a VAX 6000 system by installing KA65A processor

boards when:

The customer already has a VAX 6000 Model 500 system and simply

wants to add more KA65A processors.

The customer is upgrading to a Model 500 from a Model 300 or 400 that

is equipped to supply +3.3V power to the KA65A.

The customer is upgrading to a Model 500 from a Model 200, 300, or 400

system that is not equipped to supply the +3.3V power needed by the

KA65A. In most cases, you install the H9657-CX upgrade kit, which

consists of a power regulator module and a bus bar. This is cheaper

and simpler than solution , but there are some limitations on the

new conﬁguration.

Again, the customer is upgrading to a Model 500 from a Model 200, 300,

or 400 system that is not equipped to supply the +3.3V power needed

by the KA65A. However, this case requires a full power and packaging

upgrade.

In this upgrade, you disregard the H9657-CX kit, and instead install

the H9657-CU upgrade kit. With this upgrade, you replace most of

the major power elements of the system, achieving the same power

environment as that available with a factory-built Model 500.

The H9657-CU installation is described in the VAX 6000 XMI

Conversion Manual.

NOTE: If you order a Model 500 processor (KA65A) for cases , , and ,

you will receive an H9657-CX upgrade kit automatically. You only need this

kit for case . Disregard it for the other situations.

Section 1.2 compares the upgrades in and . Section 1.3 tells what

sections of this manual you need to read for the various upgrade paths.
