Removing and installing a power supply
Use this procedure to remove and replace a power supply. The SAN384B can
continue operating during the replacement if the other power supply is operating.
Note: The SAN384B base configuration includes two power supplies for full
redundancy. Operating the system with a single functioning power supply
runs the risk of data loss in the event of a second power supply failure. Both
power supply slots should remain filled to ensure proper air circulation for
system cooling.
Time and items required
The installation procedure for each power supply takes less than 5 minutes. A
power supply unit or filler panel is required for the power supply installation.
