Before you begin
Observe the following precautions when replacing the cache DIMMs
on a controller.
CAUTION:
HP recommends that you perform the replacement procedure
within seven minutes. Ensure all necessary parts are available
so the procedure can be completed without interruption.
Removing a controller module significantly changes the air flow
within the enclosure. Both controllers must be installed for the
enclosure to cool properly. If a controller fails, leave it in place
in the enclosure until a new module is available to install. The
enclosure could shut down due to overheating unless the
controller is replaced within the recommended seven minutes.
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
Alloy (gray)-colored latches on components like the controller means
the component is warm-swappable. Halt the I/O of a controller being
serviced with HP P6000 Command View before removing this com-
ponent.
There are two controllers at the rear of the controller enclosure. See
Figure 1
for the locations.
Your controller enclosure model may vary slightly from what is illus-
trated in this document.
