A system can have up to four memory modules. Memory modules are available
in 32 MB (MS690–BA), 64 MB (MS690–CA), and 128 MB (MS690–DA), and
can be used in any combination. The firmware logically configures the memory
modules at power-up.
Note
The MS690–BA may not be used with the KA692 or KA694 CPU
modules.
3.1.1 Installing Add-On MS690 Memory Modules
Perform the following steps to install add-on MS690 memory module(s). You do
not set any jumpers or switches on the memory module. The memory address
for the memory module is mapped by the system.
Caution
Turn off the system before installing modules. Installing modules while
this system is powered up can damage the modules.
1. Two captive screws hold the console module (H3604) in place. To loosen,
both screws should be turned counterclockwise. The console module is
hinged on the left. Swing the assembly open.
