Removing and Replacing Power Module

If you are operating your E300 chassis with a redundant AC Power Supply, you can install, remove, or
replace a power supply without affecting system operation. If you are operating your E300 system with
only three Power Supplies (the minimum), you must completely power off the system to replace a power
supply.
NOTE: If there is a power module failure (the Status LED is not lit, major alarm LED is lit, and audible alarm
sounds from the RPM), the entire unit must be replaced. There are no field serviceable parts inside the unit.
CAUTION: The power supply cord is used as the mains disconnect device, ensure that the socket-outlet is
located/installed near the equipment and is easily accessible so that the plug can be disengaged.
