Upgrading a System without +3.3V by

Installing an H9657-CX Kit

If you have a system that does not have a +3.3V XMI, the H9657-CX kit

lets you upgrade the system to a Model 600 without going through the full

power and packaging upgrade (kit H9657-CU).

This chapter assumes that you have powered the system down as described

in Chapter 2. Sections include:

• Contents of the H9657-CX Kit

• Conﬁguration Rules for the H9657-CX Kit

• Installing the Bus Bar

• Installing the T2019 Module

NOTE: The H9657-CX kit, consisting of a power regulator module and a bus

bar, is provided with KA66A processor modules for upgrades from Model

200, 300, or 400 systems. You do not use the kit in all cases, however.

The H9657-CX kit is only used for an upgrade from a system that does not

supply +3.3V, and where the following conditions hold:

• No battery backup is needed

• No more than 4 processors are needed

• No more than 12 XMI slots are needed
