Replacing the Cisco 3725 Cover

To replace the router cover, follow these steps:

Step 1 Place the chassis so that the front panel faces you. Make sure that all cables are securely tucked in and are not in danger of being stressed or cut.

Step 2 Hold the cover at a 45-degree angle, and insert the tabs into the slots along the front (bezel) edge of the chassis to engage the hinges. (See Figure 5 part 1.)

Step 3 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. (See Figure 5 part 2.)
