Connecting the RPM to the PMU
Turn off the system and disconnect the power cord before connecting or disconnecting the
RPM to or from the PMU. Failure to do so may result in RPM or PMU damage, possibly
voiding the warranty.
The RPM is matched to a PMU card and channel. Make sure to connect the RPM only to that PMU
card and channel.
With system power off, use the supplied RPM cable to connect a 4225-RPM to the matching RPM
channel of the 4225-PMU (see following figure).
