Installing and Maintaining the E1200i System 69
If you are operating your E1200i DC chassis with redundant Power Supplies, you can install, remove, or
replace a Power Supply without affecting system operation. If you are operating your E1200i DC system
with only one Power Supply (the minimum), you must completely power off the system.
Note: If there is a Power Supply failure (Power Supply LED is not lit or major alarm LED is lit), the entire
Power Supply Module must be replaced. There are no field serviceable parts inside the Power Supply unit.
