This completes the LED board installation.
Proceed to the next section to restart the system and verify that the new LED board functions
correctly.
Keep the spring depressed as you pull the board straight out at a 90-degree orientation to
the backplane.
Place the board in an antistatic bag if returning it to the factory.
Ensure that the power supplies are still turned OFF and disconnected from the power
source, and that you are still wearing a ground strap.
Handle the LED board by the edges only to avoid damage from ESD.
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 3.)
Slide the back edge of the board (the end with the connector) into the guides in the plastic
brackets. (See Figure 3.)
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.
Slowly release the spring and allow it to spring up against the chassis ceiling.
A steel pin at the front of each bracket holds the board in place (see Figure 3). On each side,
place your thumb underneath the pin and your forefinger on top of the bracket to support
it, and press the pin up through the guide in the board. If the pin does not extend fully
upward, push the board firmly into the backplane connector until the pins align with the
guide holes in the board.
Refer to the section "Replacing the Panels" on page 9 to replace the top and bottom front
chassis panels before you restart the system to verify the installation.
