Cisco 7000 and Cisco 7507
LED Board Replacement Instructions
78-1060-02
Product Number: MAS-7KLED
This document contains instructions for replacing the top and bottom front chassis panels and the
LED board in the Cisco 7000 and Cisco 7507.
Note The LED board installation and functionality are identical for both chassis; therefore,
throughout this document, both chassis are referred to as the chassis, with differences clearly noted.
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.
The sections in this document include the following:
Product Overview, page 2
Prerequisites, page 5
Removing and Replacing the Front Chassis Panels, page 7
Removing and Replacing the LED Board, page 12
Cisco Information Online, page 20
Caution The following applies to Cisco 7000 chassis only: if you remove AC-input power supplies
from a Cisco 7000 and replace them with DC-input power supplies, you might need to replace the
LED board in the chassis, if it was shipped before November 1, 1994. In this earlier chassis, the LED
circuitry will not recognize and indicate the presence of the new DC-input power supplies. If
replacement is necessary, use this document to replace the LED board. (This document is also
available on UniverCD.)
If the chassis was shipped after November 1, 1994, no LED board replacement is required.
