The switch mustbe offline.An error message would look similar to the following example:310*"011$5310*"0#135310*R1$ & The portLoopbackTest verifies the intended functional operation of the switch bysending frames from each port’s transmitter back to the same port’s receiver by wayof an internal hardware loopback.Pressing while the portLoopbackTest window is selected displays areminder to take the switch offline, if it is not offline. If the message is displayed, takethe switch offline.The portLoopbackTest is an internal test which continues to run until you press anybutton. While the test is running, all GBIC module front panel LEDs rapidly flickergreen indicating that the test is finding no errors and is processing.To stop the test, press any button and 0 is displayed.An error message would look similar to the following example:310*11$5310*9%/$31(35310*R1$5310*$1(%=$5310*(//#$0$5310*(//#$0$5310*#$0$#5310*30$05310*9%/$0;#($ & The crossPortTest verifies the intended functional operation of the switch by sendingframes from each port’s transmitter by way of the GBIC and external cable and back toanother port’s receiver. It exercises the entire path of the switch.Figure 5-1 is a recommended connection when executing the crossPortTest com-mand. The cables need not be connected. A port can be connected to any port in thesame switch provided the connection is of the same technology, meaning copperports must connect to copper ports, SW ports to SW ports, and LW ports to LW ports.
