Features
Power supply
In its basic configuration, the server has a fixed power supply unit.
Optionally, one or two redundant hot-plug power supply units are available. If
one power supply unit fails, the second power supply unit in the redundant
configuration ensures operation can continue uninterrupted. The defective
power supply unit can be replaced during operation (for further details see
section
“Hot-plug power supply units” on page 95
).
Both power supply unit versions automatically adjust to a mains voltage in the
range of 100 V - 240 V.
Cooling
Each CPU has its own heat sink and a CPU fan.
The server is cooled by four system fans (redundant configuration).
If there are four system fans, each two form a redundant pair.
If one system fan in one redundant pair fails, the other fan ensures operation
can continue uninterrupted. A defective system fan can be replaced during
operation (for further details see
“Replacing hot-plug CPU/system fans” on
The power supply fans are fitted in the respective power supply unit.
