8U SuperBlade User’s Manual
5-6
Therefore the following redundancies apply to your system when, as an example,
2200W power supplies fail.
• If one PSU fails, then you have 6600 Watts available. The CMM will detect the
remaining power left for the whole system. But because the total blade power usage
is only 3750 Watts, every blade can still work properly.
• If 2 PSUs fail, then only 4400 Watts are left available to support the blade power
usage. The system can still support all ten blades running in it.
• If 3 PSUs fail, then the remaining 2200 Watts available cannot support the whole
system. Therefore the CMM will start to shut down or throttle down the load in order
to keep blades running based upon the priority settings that were made for each
blade using the IPMIView application until the load is enough to power the
remaining blade modules.
5-3 Power Supply Fans
Each power supply unit has two to four rear fans. These fans are not hot-swappable. If
one fails, the power supply will continue to operate but you should replace the power
supply unit at the earliest opportunity. If two or more fans fail, the power supply unit will
shut down and the LED on the back will turn amber.
