Installing an M40e AC Power Supply

To install an AC power supply (see Figure 1):

1. Verify that the power switch on the power supply faceplate is in the OFF (O) position.
2. Locate the power cord shipped with the router, which should be appropriate for your geographical location (see M40e AC Power, Connection, and Power Cord Specifications).
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
4. Place one hand under the power supply and grasp a handle on the faceplate with the other hand. Slide the power supply into the chassis until it contacts the midplane.
5. Starting with the bottom screws, tighten (but do not overtighten) the thumbscrew at each corner of the power supply faceplate.
6. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply faceplate and insert the plug into an AC power source receptacle. Verify that the power cord does not block access to router components or drape where people could trip on it.

   Note: The AC power source must supply 220 VAC power (nominal range 200–240 VAC), not 110 VAC power (nominal range 100–120 VAC).

7. Press the power switch on the faceplate to the ON ( | ) position. Verify that the green LED labeled OUTPUT OK on the faceplate blinks rapidly for a short time, then lights steadily.

   Note: After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off. If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, see Disconnecting AC Power from the M40e Router or Disconnecting DC Power from the M40e Router. After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply, show chassis commands, and messages on the craft interface LCD—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
