Reinstalling the Power Supplies

The two power supplies are located at the bottom rear of the chassis, as shown in Figure 2. To reinstall the power supplies, follow this procedure (see Figure 55):

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Verify that the power switch for each power supply is in the OFF (O) position. The switches are on the circuit breaker box.
3. 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.
4. Starting with the bottom screws, tighten (but do not overtighten) the thumbscrew at each corner of the power supply faceplate.
5. Repeat the procedure to reinstall the second power supply.
6. To continue the installation, proceed to Connecting the Router and Performing Initial Configuration.
