If this circuit board installation is a permanent change to the size of the matrix,
the system will need to virtualized to recognize the change. Virtualize the
system using the detailed instructions in chapter 3, Virtualization/Control
Software.
If this BME does not have redundant power supplies, the switcher may or may
not shut down for an out of tolerance voltage.
The power supply modules are hot-swappable. If this BME has redundant
power supplies A and B, each power supply can be removed without powering
down the switcher. If the BME does not have power supply redundancy,
removing either primary power supply will shut down the matrix.
Cause
One of the power
supply voltages is out
of tolerance.
Cause
There is an airflow
restriction or one or
more of the fans is not
moving as much air as
expected.
