About AC power supplies
The VIPRION
®
4800 platform supports up to four hot swappable power supplies.
The platform supports power redundancy, which ensures that the system is unaffected if a single power
supply fails in a system containing more than one power supply. In the event of a power supply failure, you
can replace a failed DC power supply without powering down the system. For maintenance, you can replace
a working power supply, provided that there are working redundant supplies installed in the system. There
must be two or more working power supplies if 1-3 blades are installed. There must be three or more working
power supplies if 4-8 blades are installed. The system can operate without redundancy at max capacity with
two of the four power supplies installed.
