This document describes how to install an adapter plate in Cisco 3640 routers for use with the Cisco Redundant Power System (RPS). The Cisco RPS provides power system redundancy to external devices (such as routers, switches, or hubs). The system includes two fully redundant AC input power modules and four DC output power modules for connection to external devices. The Cisco RPS supports quasi-redundant and fully redundant power source configurations. To use the Cisco RPS with Cisco 3640 routers, you must remove the existing power supply and replace it with a Cisco RPS adapter plate.
This document includes the following sections:

Follow these guidelines when working on equipment powered by electricity:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
This kit includes the following items:
To install the Cisco RPS Adapter Plate, you will also need the following tools and equipment (which are not included):
To install the Cisco RPS adapter plate in Cisco 3640 routers, you need to perform the following procedures, which are described in this section:
You must remove the chassis cover to access the internal power supply.
Take these steps to remove the chassis cover:
Step 2 Attach an ESD-preventive wrist strap.
Step 3 Disconnect all network interface cables from the rear panel of the router.
Step 4 Place the router so that the front panel is facing you. Remove the three screws located on top of the cover near the front edge, as shown in Figure 2.
Step 5 Lift the front edge of the cover until it clears the front of the chassis, as shown in Figure 2.
Step 6 Pull the cover toward you until the metal tabs on the rear edge separate from the chassis bottom, as shown in Figure 2.
Step 7 Lift the cover until it is free from the chassis and then set it aside.
This section describes how to remove the internal power supply. Although the AC power supply is shown in the illustrations that follow, the procedure is the same for removing both the AC and DC power supplies.
Take these steps to remove the power supply:
Step 2 Locate the two small two-pin connectors used to power the fans. Grasp the two halves of each connector firmly and pull them apart. (See Figure 4.)
Note If cable tie-wraps on the harness interfere with removing the connectors, cut the tie-wraps, being careful not to cut the power supply wires.
Step 3 If your Cisco 3640 router has an EMI shield as shown in Figure 5, remove the screw that secures the EMI shield to the power supply. Retain the screw for later use.
Step 4 Remove the two mounting screws that secure the power supply to the chassis and set them aside. (See Figure 6.)
Step 5 Slide the power supply slightly forward in the chassis. This disengages the built-in hook that helps secure the power supply to the chassis. (See Figure 7.)
Step 6 Lift the power supply out of the chassis.
Take these steps to install the adapter plate:
Step 2 Attach the DC power rating label over the ratings on the rear panel of the router. (See Figure 9.)
Step 3 Align the Cisco RPS Adapter Plate with the chassis cutout for the power supply and the built-in hook. Then slide the adapter plate toward you, making sure that the built-in hook engages. (See Figure 10.)
Step 4 Connect the eight-pin connector to the system board. The power connector is keyed so that it cannot be connected to the system board incorrectly. (See Figure 11.)
Step 5 Reconnect the two small two-pin connectors used to power the fans. (See Figure 11.)
Step 6 Connect the 4-pin environmental status connector only if your router, with the connector connected, has been upgraded to the correct level of IOS. Using any other level of Cisco IOS software can cause the router to crash. Version 11.1(12)AA or later is compatible, but will not show status from the RPS. Version 11.2(7)P or later will provide RPS status information to the network.
Step 7 Install the screws that were removed from the power supply into the screw holes. (See Figure 12.)
Step 8 If you removed the screw from the EMI shield in Step 3, reinstall the screw to secure the EMI shield to the adapter plate. (See Figure 13.)
Follow these steps to replace the cover:
Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom, as shown in Figure 14.
Step 3 Push the cover toward the rear, making sure that the cover tabs fit under the chassis back panel, and the back panel tabs fit under the top cover.
Step 4 Lower the front of the cover onto the chassis, making sure that the side tabs on the cover fit inside the chassis side panels, and the chassis tabs fit under the cover side panels.
Step 5 Secure the cover with the three screws you set aside earlier.
Step 6 Reinstall the chassis on a rack, wall, or desktop.
Step 7 Reconnect all cables.
Step 8 Remove your ESD-preventive wrist strap.
Step 9 Power ON the router.
Use the following step to attach the warning label to the router:
