Power Supply Units Power Supply Concept

VCAUTION!

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 figure 94) on the front of the PSU dummy module for monitoring the status of built-in fans.
