NOTE: As credits are used, the Logged-In LEDs on the corresponding donor ports illuminate continuously.
In addition, donor port Activity LEDs reflects the same traffic as the recipient port. Donor ports whose
credits are being used are unavailable for device connections.

Moving a licensed port

The mPort Technology feature enables you to move a port license from one SFP port to another SFP port
that is currently unlicensed. If all SFP ports are licensed, this feature does not apply.
To move a port license:
1. Select Port > Move Port License to open the Move Port License dialog box
2. Select the source port from the Source Port drop-down list.
3. Select the destination port from the Destination Port drop-down list.
4. Click Move to move the license to the destination port.
5. Click Close to close the dialog box.

Resetting a port

The Reset Port option reinitializes the port using the saved configuration. To reset a port:
1. In the faceplate display, select the port(s) to be reset.
2. Select Port > Reset Port.
3. Click Yes to reset the selected port(s).

Testing ports

You can test a port using the Port Diagnostics dialog box. Only one port can be tested at a time for each
type of test. The Port Diagnostics dialog box
• Internal is 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 is 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 is 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.
