CAUTION!
Because of chassis airflow disruption, the power supply unit slot should
not be vacant and/or uncovered for more than five minutes when the
system power is ON. Exceeding the five-minute limit may damage com-
ponents.
Each PSU dummy module includes three fans respectively.
There is one LED indicator (1 on
figure 80
) on the front of the PSU dummy
module for monitoring the status of built-in fans.
