You might need to locate the voltage regulator modules on the
system backplane. This section includes information on the locations of the
voltage regulators.
The system backplane
A contains three
voltage regulator modules. The following figure shows the location of two
1.3 V dc modules
C and the 2.5 V dc module
B.
(Your system might have only one 1.3 V dc module.)
