Internal Loopback
Test
An internal loopback test checks internal port, serializer, and
deserializer circuitry and checks for the presence of an optical
transceiver, but does not check fiber-optic components of the
installed transceiver. Operation of the attached device is disrupted
during the test. To perform the test:
1. Inform the customer a disruptive internal loopback test is to be
performed. Ensure the system administrator quiesces Fibre
Channel frame traffic through the port and sets the attached
device offline.
NOTE: A small form factor pluggable (SFP) optical transceiver must be
installed in the port during the test. A device can remain connected
during the test.
2. At the Element Manager application (management server), select
Port Diagnostics from the Maintenance menu. The Port Diagnostics
dialog box displays (Figure 4-14).
3. Type the port number to be tested or select all ports at the Port
Select area of the dialog box.
4. At the Diagnostics Test list box, select the Internal Loop option.
5. Click Next. The message Press START TEST to begin diagnostics
appears, and the Next button changes to a Start Test button.
