120 Sun Storage Fibre Channel Switch 5802 QuickTools User Guide September 2008
Internal — a disruptive test that verifies 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 ports. The port passes the test if the frame that was sent by the ASIC
matches the test frame that was received. This test requires that the port be in
diagnostics mode, and therefore, disrupts communication.
External — a disruptive test that verifies port circuitry. The SFP level test sends a
test frame from the ASIC through the SerDes chip, through the SFP transceiver
fitted with an external loopback plug, and back to the ASIC for the selected ports.
The port passes the test if the test frame that was sent by the ASIC matches the
test frame that was received. This test requires that the port be in diagnostics
mode.
Online — a non-disruptive test that verifies communications between the port
and its device node or device loop. The port being tested must be online and
connected to a remote device, and therefore, does not disrupt communication. The
port passes the test if the frame that was sent by the ASIC matches the frame that
was received.
