Troubleshooting
3.1
Self-testing
When the device is powered on, the Power LED will be illuminated showing that there
is power to the unit. The RUN LED will be either on, flashing or off depending on the
DIP switch setting (see Page 9).
3.2
Twisted Pair Port Testing
As shown in Figure 3.1, with the switch powered on, connect two RJ45 ports from
the switch to two test computers and send the “ping” command between each
computer. If both the computers receive the complete command without packet loss
and the green LED flashes, this means that the two RJ45 ports are working correctly.
Test the other RJ45 ports as required, using the same method. During normal
operation the green ACT LED will flash to show data transfer and the yellow LINK
LED will either be off to show 10Mbps (10BASE-T) operation or on to show 100Mbps
(100BASE-TX) operation.
