Removing the Power Supply Assembly from a Cisco 3825 Router

Step 3 Remove the router from the rack. Remove the rack-mounting brackets from the router using the number 2 Phillips screwdriver.

Step 4 Place the router on a flat surface. Remove the three screws from the top of the router and set them aside in a safe place.

Step 5 Remove the three screws on each side panel and set them aside in a safe place.

Step 6 Slide the cover toward the front of the chassis (about 1 inch [25 mm]). See Figure 48. Step 7 Lift the cover away from the router base.

Step 8 You must remove the Cisco 3825 power supply to replace it or to access components on the motherboard. Continue with the “Removing the Power Supply Assembly from a Cisco 3825 Router” procedure on page 81.
