Removing and Replacing AC Power Supplies

If you are operating your E1200i AC chassis with redundant Power Supplies, you can install, remove, or replace a Power Supply without affecting system operation. If you are operating your E1200i AC system with only two Power Supplies (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.

Danger: Do not remove the AC-Cord Retainer until the power supplied by the remote power source is OFF.
