The LEDs may not light until the module has been configured in Hardware Configuration Utility or MAX. Before proceeding, verify that the module appears in Hardware Configuration Utility or MAX.

If the module appears in Hardware Configuration Utility or MAX but the ACCESS LED fails to light after you power on the chassis, a problem may exist with the chassis power rails, the hardware module, or the LED.
