FINSTRATE INSTALLATION
INSTRUCTIONS FOR HP-QUALIFIED PERSONNEL:
Start on page 2-6 (RAM/CPU), or 2-7 (lOP) and follow the instructions that apply to the installation
you are performing. For example,
if you are installing a 2nd lOP in a 520 computer you would start
on page 2-7, and perform all steps that begin with: (ALL), (ALL 2nd lOP), (ALL EXCEPT 520-3rd
lOP), (520), (520 ONLY), and (520-2nd lOP).
ALL RAM and CPU Instuctions start on 2-6.
ALL lOP Instructions start on 2-7.
When completed with the installation of the finstrate, Insert the following pages in your CE Hand-
