Reinstall the Power Supplies

The router has two power supplies (either AC or DC) located at the bottom rear of the chassis (see Figure 2). To reinstall the power supplies, follow this procedure (see Figure 46, which shows an AC power supply):

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Verify that the power switch on the faceplate of both power supplies is in the OFF (O) position.
3. Grasp the handle on the power supply faceplate with one hand and place the other hand under the unit to support it.
4. With a finger of the hand that is grasping the handle, lift and hold up the safety interlock lever. (On an AC power supply, the lever is just below the appliance inlet. On a DC power supply, it is just below the power switch.)
5. While holding the safety interlock lever up, slide the power supply into the chassis until it contacts the backplane.
6. Still holding the safety interlock lever up, turn the extractor/inserter clockwise until the power supply engages with the connectors on the backplane.
7. Push the safety interlock lever down.
8. Using a Phillips screwdriver, tighten (but do not overtighten) the thumbscrew at each upper corner of the power supply faceplate.
9. Repeat Steps 3 through 8 to reinstall the second power supply.
