Preface
USB ports
The three USB ports on the front of server support activities carried out by the
service technician. The maximum length of the external cable are three meters.
Power supply
The basic configuration of the server includes a hot-plug power supply unit,
which automatically sets itself to a mains voltage in the range of 100 V - 127 V
oder 200 V - 240 V. As an option, the power supply can be expanded with an
extra power supply unit to create a redundant power supply. If a power supply
unit fails, the redundant configuration assures continued operation. The
defective power supply unit can be replaced during operation (for further details
see section
"Hot-plug power supply units" on page 80
).
Cooling
The Cool-safe™ cooling concept with improved air flow cooling technology
(honeycomb design) ensures the highest possible performance of the
processors at work; at the same time, the system is extremely reliable thanks to
the reduced heat dissipation.
Each processor has a heat sink. Further cooling for the installed processors is
provided by six fan units (redundant). If
one
fan
in a
redundant unit fails, the
system is able to continue operating without limitations. If a fan fails, it can be
replaced while the system is running (for further details see section
