Redundancy

This section describes the redundant components of the system unit.
Power supply
Installation of two power supplies on the system unit enables power supply
duplication.
This allows continuous operation without shutting down the system unit if either
of the power supplies fails. Each power supply supports a hot plug. Therefore, a
failed power supply can be replaced without shutting down the system unit.
We recommend connecting two power supplies to different power sources,
respectively, if installed. In case of a failure on one power source, the system
unit can operate without a shutdown, as long as power is still supplied from the
other source.
System fans
The system unit has system fans for internal cooling. Some of these fans are
designed to be redundant.
The system unit can operate without a shutdown even if one of the system fans
fails.
If a failure occurs in one power supply, contact the sales representative
or maintenance personnel.
Replace the failed power supply as soon as possible.
If a system fan failure occurs, contact the sales representative or
maintenance personnel.
Replace the failed system fan as soon as possible.
