    Removing an M40e AC Power Supply

    The AC power supplies are located at the bottom rear of the chassis, as shown in M40e Chassis Description. Each AC power supply weighs approximately 15 lb (6.8 kg).

    Caution: Do not leave a power supply slot empty for more than 30 minutes while the router is operational. For proper airflow, the power supply must remain in the chassis, or a blank panel must be used in an empty slot.

    To remove an AC power supply (see Figure 2):

    1. 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.
    2. Press the power switch on the power supply faceplate to the OFF (O) position.

      Note: If you are not removing the power supply, but simply powering it off, wait at least 60 seconds before turning it back on. If you need to power it off again, wait for at least 60 seconds after powering it on.

    3. Unplug the power cord from the appliance inlet on the faceplate.
    4. Loosen the thumbscrew at each corner of the power supply faceplate, using a Phillips screwdriver if necessary.
    5. Grasp the handle or handles on the power supply faceplate and pull firmly to slide the unit about halfway out of the chassis.
    6. Place one hand under the power supply to support it, then slide it completely out of the chassis.

    Warning: Do not touch the power connectors on the rear of the power supply (see Removing an M40e DC Power Supply). They can contain dangerous voltages.
