Installing the H9657-CX Kit
If you have a VAX 6000 Model 200, 300, or 400 system that does not have a
+3.3V XMI, the H9657-CX kit lets you upgrade the system to a Model 500
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 KA65A processor modules when the customer is
upgrading from a VAX 6000 Model 200, 300, or 400 system. You do not
use the kit in all cases, however. The H9657-CX kit is only used for an
upgrade from a VAX 6000 Model 200, 300, or 400 system with an XMI 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
