Appliance X6 series. Refer to the preceding chapters in this document for information on

Oracle Database Appliance Version 1 is equipped with two hot pluggable power supplies. They
are redundant, meaning that the system can operate with a single power supply. This allows you
to remove and replace a power supply without shutting the system down.
If a power supply fails and you do not have a replacement available, to ensure proper airflow,
leave the failed power supply installed in the system.
