Note - The server will not boot unless all 12 power supplies are installed.
Although the server requires that 12 power supplies be installed, it can operate with a minimum of six functioning power supplies. If there are only five functioning power supplies, the server will cease operations:
If the DCUs are on, they will shut down.
If the DCUs are off, they cannot be turned on.
If you encounter this situation, turn on both facility power grids to ensure that 11 power supplies are functioning before you replace a faulty power supply.
The following table shows which power supplies, AC power cords, and AC input filters receive AC power from the two facility power grids.
See the Installation Guide for detailed information about power grids.
