5. To verify that the Control Board is installed correctly and functioning normally:
• Connect an Ethernet cable to the HOST/ETHERNET port on the Control Board. If the host
subsystem is operational, the ACT port LED is lit to indicate Ethernet activity. If you can run the
CLI from a management device attached to the Control Board, the Control Board is installed
correctly.
• Verify that the green OK LED on the Control Board faceplate is lit steadily green. The green OK
LED should light steadily a few minutes after the Control Board is installed.
• Verify that the FAIL LED on the Control Board faceplate is not lit. If the FAIL LED is lit steadily,
remove and install the Control Board again. If the FAIL LED still lights steadily, the Control Board
is not functioning properly. Contact your customer support representative.
