Tsunami QB-8100 Series (100 Mbps/5 Mbps Models) Installation and Management Guide 188
8.1 PoE Injector
8.1.1 The Unit Does Not Work
1. Verify that you are using a standard UTP Category 5 cable.
2. Try a different port on the same PoE injector hub (remember to move the input port accordingly) – if it works, there is
probably a faulty port or bad RJ-45 port connection.
3. If possible, try to connect the unit to a different PoE injector hub.
4. Try using a different Ethernet cable – if it works, there is probably a faulty connection over the long cable, or a bad
RJ-45 connection.
5. Check power plug and hub.
6. If the Ethernet link goes down, check the cable, cable type, switch, and hub.
8.1.2 There Is No Data Link
1. Verify that the indicator for the port is “on.”
2. Verify that the PoE injector hub is connected to the Ethernet network with a good connection.
3. Verify that the Ethernet cable is Category 5 or better and is less than 100 meters (approximately 325 feet) in length
from the Ethernet source to the QB-8100 unit.
4. Try to connect a different device to the same port on the PoE injector hub – if it works and a link is established, there
is probably a faulty data link in the unit.
5. Try to re-connect the cable to a different output port (remember to move the input port accordingly) – if it works,
there is probably a faulty output or input port in the PoE injector hub or a bad RJ-45 connection.
8.1.3 Overload Indications
1. Verify that you are not using a cross-over cable between the PoE injector output port and the unit.
2. Verify that there is no short over any of the twisted pair cables.
3. Move the device into a different output port (remember to move the input port accordingly); if it works, there is
probably a faulty port or bad RJ-45 connection.
8.2 Connectivity Issues
8.2.1 QB-8100 Does Not Boot
The QB-8100 shows no activity (the power LED is off).
1. Ensure that the power supply is properly working and correctly connected.
2. Ensure that all cables are correctly connected.
3. Check the power source.
4. If you are using an Active Ethernet splitter, ensure that the voltage is correct.
5. If you are using PoE injector, make sure you are using a Category 5, foiled, twisted pair cable to power the unit.
8.2.2 Ethernet Link Does Not Work
1. First check the Ethernet LED:
• Solid Green: Ethernet is up.
• Blinking Green: Ethernet is down.
2. Verify pass-through versus cross-over cable.
