Notes:
1. During normal operation, both power supplies must be installed for proper
operation cooling.
2. The xSeries 440 server requires a 220 V power connection for full power-supply
redundancy. Whenever possible, use a 220 V connection for all configurations.
However, you can use a 110 V connection without power-supply redundancy.
Note:
Before you continue working with power supplies, review the following information.
