Performing Diagnostics on Ports
Choose Operations from the navigation panel. Choose the Port tab and the
Diagnostics tab; the Diagnostics tab view displays (Figure 6–6 on page 6-8). Use this
view to run either internal or external loopback diagnostic tests for any port. (Service
personnel may request these tests to be conducted to aid in troubleshooting problems.)
• Internal loopback test - an internal loopback test checks internal port, serializer,
and deserializer circuitry.
• External loopback test - an external loopback test checks all port circuitry,
including fiber-optic or copper components.
