Removing the LED Board

Installing a New LED Board
Cisco 7000 Front Chassis Panel and LED Board and Replacement 11
To remove the existing LED board, perform the following steps:
Step 1:
Ensure that all system power is turned OFF and that power cords are
disconnected from the power supplies or the power source.
Step 2:
Follow the steps in "Removing the Panels" on page 7 to remove the top and
bottom front chassis panels.
Step 3:
If you have not already done so, slip on an ESD-prevention grounding strap.
(A disposable wrist strap is included with all spare boards.) Connect the
equipment end of the strap to an unpainted surface inside the chassis, such as
the metal frame that is exposed when the front panels are removed.
Step 4:
Locate the LED board (see Figure 3), which is mounted on a horizontal plane
in two plastic brackets near the top of the chassis.
Step 5:
Two steel pins near the front of the brackets hold the board in place (see
Figure 4). On each pin, place your thumb on the top of the pin and your
forefinger underneath the bracket to support it, and press the pins down and
out of the guide holes in the board.
Caution:
Handle the LED board by the edges only to avoid damage from ESD.
Step 6:
Grasp the edges of the board and place a finger on the top of the LED board
spring to depress it.
Step 7:
Keep the spring depressed as you pull the board straight out at a 90-degree
orientation to the backplane.
Step 8:
Place the board in an antistatic bag if returning it to the factory.
To install the new LED board, perform the following steps:
Step 1:
Ensure that the power supplies are still turned OFF and disconnected from
the power source, and that you are still wearing a ground strap.
Caution:
Handle the LED board by the edges only to avoid damage from ESD.
Step 2:
Hold the board with the LEDs toward you, with the spring on the top, and
with the LEDs and components on the underside of the board.Grasp the
edges of the board and place a finger on the top of the LED board spring to
depress it (see Figure 4).
Step 3:
Slide the back edge of the board (the end with the connector) into the guides
in the plastic brackets (see Figure 4).
Step 4:
Keep the spring depressed as you push the board straight in at a 90-degree
orientation to the backplane until the connector on the LED board is fully
seated in the backplane connector.
