2.8.2 Redundant power supply units
To replace a power supply unit (PSU):
1. Disconnect the power cable, then lift the PSU lever.
2. Hold the PSU lever and press the PSU latch (A), then carefully pull the PSU out of the
system chassis (B).
To enable the hot-swap feature (redundant mode), ensure that at least two working
power supplies are installed.
We recommend that you use both of your hands in performing the following steps.
Always use PSUs with the same watt and power rating. Combining PSUs with different
wattages may yield unstable results and potential damage to your system.
For a stable operating environment, make sure that at least two (2) working power
supply units are connected before turning on the system.
For a steady power input, use only the power cables that come with the server system
package.
