UTP AND THIN ETHERNET REPEATERS
• A length of phone wire is connected, but there is nothing at the other
end of the line.
• A length of phone wire is connected, but there is a short circuit in the
cable at or near the repeater.
• The polarity of the phone wire connecting two Repeaters is reversed
(pin 3 of one jack is connected to pin 4 of another) and the wire is less
than 150 feet (45.7 m) long.
• One repeater is not powered.
• There is a break in the wire.
3. The LEDs on a 10BASE2 port alternate when:
• There is nothing connected to the jack.
• A length of 10BASE2 coax is connected, but there is no terminator at
the far end of the segment.
• A length of 10BASE2 coax is connected, but there is a short circuit in
the cable at or near the repeater.
• A length of 10BASE2 coax is connected, but there is a break in the wire.
When the LEDs alternate, the corresponding port is automatically
disconnected from the network. This enables the remaining portions of
the network to keep functioning until the problem is corrected.
5.2 Troubleshooting
Symptom
: No LEDs are on, and the network does not operate.
Cause
: The repeater is not powered.
Action
: Check that the external power supply is plugged into the repeater
and into a working wall outlet. Verify that the outlet is functional using
another electrical device such as a lamp. If the outlet is OK and the
repeater still does not work, call Technical Support.
Symptom
: The LEDs continue to flash even when a cable is attached.
Causes
: If any of the following causes exist simultaneously, you must
correct all of them for the port to work. The repeater automatically
disconnects the offending channel, so it is not necessary to shut down the
network to repair a problem.
Cause
: 1. There is nothing connected to the jack.
