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
components.
All unoccupied PSU slots in the blade server system are fitted with PSU dummy
modules (figure 94) to ensure that the electromagnetic emission properties of
the system are observed and that the system components are properly cooled.
Each PSU dummy module includes three fans respectively.
There is one LED indicator (1 on
module for monitoring the status of built-in fans.
Figure 94: PSU dummy module
If you want to install an additional power supply unit, you must first remove the
PSU dummy module from the corresponding slot.
