Power Supply Module
One 350-Watt plug-in power supply module (PSU) is mounted in the rear of the system.
Optionally, a second power supply module can be fitted to provide redundancy.
Figure 1-9 shows a PSU module.
Figure 1-9 Power Supply Module
Power supply voltage operating ranges are nominally 115 V or 230 V, and are selected
automatically.
In a redundant configuration, the modules operate together; if one fails, the other
maintains the power supply while the faulty unit is replaced.
Important:
Module replacement should only take a few minutes to perform but must be
completed within 10 minutes from removal of the failed module. Alternatively, if a
replacement power supply module is not available, a power supply blanking module
must be fitted after removing the faulty module.
