Ensure that the power supplies are still turned OFF.
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.
Slide the back edge of the board (the end with the connector) into the guides in the plastic
brackets. (See Figure 5-31.)
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.
Release the spring; it will spring up against the chassis ceiling.
A steel pin at the front of each bracket holds the board in place. 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 hole 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.
Replace the top and bottom front chassis panels (refer to the section "Removing and
Replacing the Front Chassis Panels" earlier in this chapter) and proceed to the following
section to verify the installation.
Turn ON the power switches on all installed power supplies.
After the system boots successfully, verify that the normal LED goes on. If it does not, do
the following:
•
Check the normal LED on the RP. If it is not on, the system has not reached normal
operating state. Refer to the troubleshooting procedures in the chapter "Troubleshooting
the Installation."
•
If the normal LED on the RP is on, the system software is functioning properly. On all
installed power supplies, turn the switch OFF and reseat the LED board by following
Steps 2 through 6 of the previous procedure, "Installing a New LED Board."
Verify that the upper and lower power LEDs light for the installed power supplies. If they
do not, check the LEDs on the AC-input (or DC-input) power supplies in the back of the
chassis as follows:
•
Check the AC power (or input power) LED on the power supply for the front panel LED
that does not light. If the AC power (or input power) LED is on, the power supply is
functioning properly. Turn OFF the system power and reseat the LED board by
following Steps 2 through 6 of the previous procedure, "Installing a New LED Board."
•
If the power supply AC power (or input power) LED is not on, or if the DC fail (or out
fail) LED is on, the power supply has failed. Refer to the troubleshooting procedures in
the chapter "Troubleshooting the Installation."
If after several attempts the LEDs do not operate properly, or if you experience trouble with
the installation (for instance, if the guide pins do not align with the holes in the board),
contact a customer service representative for assistance.
