Attaching the Installation Handle to the M320 Router

To assist you with the installation of the router, attach the installation handle over the three lowest power supply slots of the chassis. To remove the corresponding power supplies and attach the handle:

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. Switch the circuit breaker on the power supply faceplate to the off position (O). We recommend this even though the power supplies are not connected to power sources.
3. Loosen the captive screw on each side of the power supply faceplate completely.
4. Grasp the flange on each side of the power supply faceplate, placing your hand between the flange and the chassis.
5. Pull firmly to start removing the power supply. Slide it halfway out of the chassis (see Figure 1, which shows the removal of a DC power supply).
6. Place one hand underneath the power supply to support it and slide it completely out of the chassis.

   Caution: Each power supply weighs approximately 10 lb (4.5 kg). Be prepared to support the full weight of the power supply as you remove it from the router.

7. Repeat the procedure for the remaining power supplies.
8. Attach the installation handle by tightening the captive screws of the handle into the holes previously occupied by the captive screws of the power supplies in slots PEM1 and PEM3 (see Figure 2).
