SMU configuration
Minimum configuration:
One HRSMU and two MPSMUs
(default configuration)
A maximum of two HRSMUs can
be installed and connected only
to the SMU1 and SMU2 ports. A
maximum of two HPSMUs can be
installed and connected only to
the SMU3 and SMU4 ports. The
first HPSMU must be connected
to SMU3 and the second to
SMU4. The default configuration
of the 4073A has one HRSMU
(connected to the SMU2 port)
and two MPSMUs (connected to
the SMU3 and SMU4 ports). The
following tables indicate the
installation order for additional
SMUs.
One HRSMU and no HPSMU installed in
