This document contains instructions for replacing the top and bottom front chassis
panels and the LED board in the Cisco 7000. The top and bottom front chassis panels
comprise plastic bezels on a metal frame and should be replaced if they become warped
or broken. The LED board, which contains the light-emitting diodes (LEDs) for the
three front-panel system status indicators (Normal, Upper Power, and Lower Power), is
mounted inside the front of the chassis.
