Port fault LED flash patterns
The amber port fault LED is lit to indicate that the port has failed one of the following port operational tests performed with the SAN Utility or the
CLI:
•Internal
•External
•Online
If the port fault LED is lit, take the port offline and contact your Intel technical support representative.
Port testing
The port loopback tests verify correct port operation by sending a test data frame out through the loop and then verifying that the frame received matches the frame that was sent. You can perform the following port tests from the Port Loopback window:
•Internal SerDes test (internal and external ports) - The SerDes (serializer/deserializer) level test verifies internal and external port circuitry. The SerDes level test sends a test frame from the ASIC through the SerDes chip and back to the ASIC for the selected internal ports. The port passes the test if the frame that was sent by the ASIC matches the test frame that was received.
✏NOTE
A loopback plug is required to perform an external SFP test.
•External SFP test (external ports only) - The SFP level test also verifies port circuitry. The SFP level test sends a test frame from the ASIC through the SerDes chip, through the SFP module fitted with the loopback plug, and back to the ASIC for the selected external ports. The external port passes the test if the test frame that was sent by the ASIC matches the test frame that was received.
