Gigabit Ethernet Poe; Connectivity Issues - Proxim Tsunami MP-8100 Series Installation And Management Manual

8.1 Gigabit Ethernet PoE

8.1.1 The Unit Does Not Work
1. Verify that you are using a standard UTP Category 5e/Category 6 cable.
2. Try a different port on the same Gigabit Ethernet PoE 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 Gigabit Ethernet PoE 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 Gigabit Ethernet PoE hub is connected to the Ethernet network with a good connection.
3. Verify that the Ethernet cable is Category 5e or better and is less than 100 meters (approximately 325 feet) in length
from the Ethernet source to the MP-8100 unit.
4. Try to connect a different device to the same port on the Gigabit Ethernet PoE 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 Gigabit Ethernet PoE 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 Gigabit Ethernet PoE 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 MP-8100 Does Not Boot
The MP-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 Gigabit Ethernet PoE, make sure you are using a Category 5e/Category 6, 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.
