Fan Module and Power Supply Numbering
CS-Storm 500NX 1U server fan and PSU numbering.
The CS-Storm 500NX 1U chassis contains eight 9-cm exhaust fans that provide cooling for the system. Four of these fans are combined with the four hot-plug power supplies (PSUs). There is no need to power down the system when replacing fans or power supplies.
In the event of a power supply failure, the remaining power modules continue server operation. The failed power module can be hot swapped. Be sure to replace PSUs with the same model.
An amber light on the power supply is illuminated when the power is switched off. A green light indicates that the power supply is operating.
