TX200 S6 Operating Manual 19
Preface
Power supply
In its basic configuration the server has a permanently installed power supply
unit or a hot-plug power supply unit that adjusts automatically to any mains
voltage in the range 100 V - 240 V. Besides the hot-plug power supply unit, a
second hot-plug power supply unit can be installed optionally to serve as a
redundant power supply. If one power supply unit fails, the second power supply
unit in the redundant configuration ensures operation can continue
uninterrupted. The faulty power supply unit can be replaced during operation
(for further details see section "Hot-plug power supply units (optional)" on
page 92).
Cooling
In the standard configuration the server is cooled by two system fans and one
power supply fan.
In the optional, redundant configuration the server is cooled by four system fans
(two double fans) and one or two power supply fans. If one of the four system
fans fails, one of the two predetermined fans (system fan 3 and system fan 4,
see the "Options Guide" for the system) increases its power to ensure that the
server is cooled properly.
