You may install new disk units into the 5065 or 5066 Expansion Unit or yourself. It
takes approximately 1 hour to install the hardware.
You may also elect not to install the feature. Contact IBM or an authorized dealer
to make arrangements for them to install the disk unit feature for a fee.
Allow additional time to complete your jobs, back up your system, IPL your
system, and verify your hardware configuration.
When you use these instructions, you will do the following:
v
Remove the front cover for the expansion-unit.
v
Install one or more new disk units.

Your 5066 Expansion Unit consists of two independent 5065 Expansion
Units. The installation instructions for each expansion unit in your 5066 are
identical.
Before you begin:
v
Ensure that you have a current backup of your operating system and licensed
programs. If you have backed up the operating system and licensed programs
since the last time you applied PTFs, that backup is acceptable.
v
Ensure that you take a few minutes to become familiar with these instructions.
v

following:
– Your authorized dealer

Optimizing your new disk unit
When you install a disk unit, you should optimize it for maximum performance by
evenly distributing the disk units on the disk controllers.
Note:
If you are installing feature 4331 1.65 GB Read Cache, solid-state disk units,
you can only install them in position one of your disk unit enclosures. You
can install three of these features (if you have three disk unit controllers) in
the expansion unit.
Refer to the label on the inside of the front cover and install the disk units in this
sequence:
1.
First fill all the disk unit positions that are controlled by the first high speed
disk unit controller.
