When performing any troubleshooting on the TCC+ cards, first check the LEDs as follows:
1.Check the POWER LEDs on each TCC+ card. Are the POWER LEDs on each TCC+ card on (green)?
–If no, remove the TCC+ card and reinsert it, making sure that it firmly connects to the backplane and that both captive screws are tightly connected.
–If yes, proceed to the next step.
2.Is the STATUS LED on the primary TCC+ card on (green) to indicate that it is the primary card? Is the STATUS LED on the secondary TCC+ card flashing (green) to indicate that it is the redundant card?
