Figure 26 Securing the Fan Tray Screw Latch

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.

2. Grip the handle and pull the fan tray out approximately one inch from the chassis. Wait 30 seconds until

the fan blades stop rotating, then remove.

Danger: Keep fingers clear of rotating fan blades.

3. Prior to inserting a new fan tray, fully turn (with a flathead screwdriver) the screw latch

counter-clockwise until the fan tray latching mechanism retracts into the fan tray.

4. Insert the fan tray into the chassis. Guide the tray firmly into the slot until it stops and the handle end is

flush with the chassis rear.

5. To secure the fan trays into place, turn the screw latch clockwise to tighten the latching mechanism.

(see Figure 26)

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.
