Removing cache memory from the faulty controller
To remove the cache memory from the faulty controller:
1. Before removing the cache memory, record the slots where it is
installed, as you will need to install the same modules in the equivalent
slots in the new controller.
2. Push the slot levers that secure the cache memory.
3. Using both hands, gently pull up the cache memory and remove it.
4. Place the cache memory in a temporary location where anti-static
measures are observed.
Installing the cache memory on the new controller
After removing the cache memory from the old controller, install it on the
replacement controller.
1. Using both hands, hold the cache memory you removed from the old
controller and insert it into the new controller. Insert the modules into
the same slots where they were installed in the controller you removed.
2. Align the projection inside the slot with the cut on the cache memory,
and then gently push the cache memory into the slot until the slot levers
close completely.
