Planning for the rear-door heat exchanger
If the optional rear-door heat exchanger (feature code AFR1) was ordered, you
must prepare the installation site before an IBM service representative can install
the rear-door heat exchanger on any of your FlashSystem A9000R.
See the following information in order to properly plan for your rear-door heat
exchanger:
v
“Rear-door heat exchanger operating specifications”
v “Rear-door heat exchanger performance” on page 39
v “Preparing your site to provide water to the rear-door heat exchanger” on page

v “Secondary cooling loop parts and services information” on page 57
v “Maintenance schedule” on page 60
Rear-door heat exchanger operating specifications
Rear-door heat exchanger operating specifications provide detailed information for
your heat exchanger, including dimensions, weight, air source, water source, water
pressure, and water volume.
The following table shows the specifications for the rear-door heat exchanger.
