6-2 CHAPTER 6: PROBLEM SOLVING

Problems When Using Your Hub

Power LED not lit. Check your power adapter connection. If there is still no power, you may have a faulty power adapter which needs replacing with another OfficeConnect power adapter. Do not use any other power adapter with the hub.

Alert LED continuously lit. If you haven’t configured the Alert LED, it lights for two default conditions. It could be that there is either continual excessive use of your network (over 80%) or, more likely, a 10BASE-T port has partitioned due to a loop in your network (in which case a Port Status LED is yellow). Examine your connections and remove the loop. Each piece of equipment needs only one connection to your OfficeConnect hub.

If you have configured the Alert LED, check the Alerts dialog box in Quick Config Manager to see what conditions have caused the LED to light, see “Setting Up the Alert LED” on page 4-15.

Check that the Alert LED Test is disabled, in the Alerts dialog box. If it is not, select Disable and click on OK.

Port Status LED yellow for a 10BASE-T port.

It is likely that there is a loop in your network which has caused this port to partition. Examine your connections and remove the loop. Each piece of equipment needs only one connection to your OfficeConnect hub.

Port Status LED not lit for a 10BASE-T port that has a connection. There is a problem with this connection. Check you are using a ‘Straight-through’ 10BASE-T cable which is properly connected at both ends, is not damaged, and that the equipment it is connected to is powered on and operating correctly.

Link between two OfficeConnect hubs not working. Check your hub connections; follow the information given in “Connecting OfficeConnect Hubs Together” on page 2-8. With 10BASE-T it is likely an MDI/MDIX switch is set incorrectly. With 10BASE-2 (Coax) it is likely a terminator (end piece) is not fitted properly; this would cause the Coax Port Status LED to light yellow (partition).
