2-6 SPARC Enterprise M3000 Server Installation Guide • January 2009
If the computer equipment is subjected to repeated power interruptions and
fluctuations, it is susceptible to a component failure rate that is higher than it would
be with a stable power source.
The SPARC Enterprise M3000 server has the following basic connection
configurations:
■ Power cables with a redundant PSU connection (FIGURE 2-1)
■ Power cables with a dual-power feed connection (FIGURE 2-2)
To connect the power cables
in a redundant PSU connection to the same AC power
supply, connect each power cable independently to its own outlet.
FIGURE 2-1 Power Cables With a Redundant PSU Connection
For a dual-power feed connection, connect each power cable separately to each AC
power supply system.
