Replacing the Fan Assembly

WARNING: When removing a fan module, avoid contacting moving fan blades before and after
removal with tools, hands, or other objects. If removing the fan module to access or replace the
modules behind it, turn off the equipment power and allow the modules to cool before
performing any work as the surfaces of the modules can be hot.
CAUTION: To prevent overheating, this fan must be in place at all times, except during
servicing.
IMPORTANT: The fan assembly can be swapped out without shutting the power off. The
replacement fan assembly must be in place within a reasonable amount of time so that the
device module does not overheat and shut down.
