Redundant Power Supply (Optional) 

 

The redundant power supply feature consists of hot-swappable power supply modules. If one of the power modules 

failures, the remaining working modules will continue to provide power to the unit so users do not experience 

downtime. A replacement power supply could be installed while the unit is running. Once the replacement power 
supply has been installed, the unit will regain its redundant power feature. 

 

Note: Power must be supplied to all power supply modules in order for the redundant feature to operate correctly. 
 

 

Fan/Power Fail LED Information (Front Panel) 

 
When the power supply modules or internal cooling fan malfunction, the front fail LED will blink and the alarm will go
