A7 Midplane Assembly Troubleshooting
If there is an analyzer function such as a boot up issue where the power
supplies are suspect, view the power supply LED's on the Midplane Assembly
by removing the instrument outer cover. See
Figure 10-4
Midplane Assembly
As shown above, the Midplane Assembly has test points for each power supply
that can be used as measurement points. These DC voltages can be verified
with a voltmeter. Continuity measurements can also be performed on each
power supply if a shorted condition is suspect. Refer to the table below for
measurement details.
