The IONPS6-D is an DC power supply module for the ION 6-slot chassis. The ION106-D chassis ships with one DC power supply, but the system can be made redundant with the use of the IONPS-D power supply module. The second power supply module works in a load-sharing mode, however a single power supply module can be used to power a fully loaded ION chassis. The IONPS6-D supports a power input voltage range of 21VDC to 72VDC.
