Removing the T640 Router Installation Handle and Reinstalling the Power Supplies

After you have installed the T640 router, remove the installation handle and reinstall the two power supplies in the chassis, starting with the lower power supply (see Reinstalling a Power Supply):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site. For more information about ESD, see T640 Preventing Electrostatic Discharge Damage.
2. Loosen the captive screws on the installation handle completely, and remove the handle from the chassis.
3. Switch the circuit breakers on the power supply faceplate to the off position (O).
4. Using both hands, slide the power supply into the chassis until you feel resistance.
5. Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
6. Tighten the captive screws at the lower corners of the power supply faceplate to secure the power supply in the chassis.
7. Repeat the procedure for the upper power supply.
