8.3 Troubleshooting
Not all errors indicate defects in FRITZ!X USB or your terminal
equipment. This section describes the most common error
conditions with their most likely causes and remedies.
Begin by performing the following checks:
z
Do the LEDs on your FRITZ!X USB indicate normal
operation? The LED signals are described in the section
“LEDs FRITZ!X USB” on page 12.
z
Is FRITZ!X USB operational? The green LED labeled
“Power” should be lit.
z
Test the “Phone” LED for each extension:
If you pick up the handset of an extension phone, or if the
extension has an active connection, this is indicated by
an amber LED. Incoming calls are indicated by a blinking
LED.
If the LED does not light up when you pick up the
handset, this probably indicates a fault in the
telephone cord or a wiring error in the connector. Test
all the extensions one after another.
z
Is the USB cable securely connected to the computer
and FRITZ!X USB?
z
Is the power adapter securely connected to the AC
outlet and FRITZ!X USB?
z
Is the ISDN cable securely inserted in the ISDN socket of
your NT (Network Terminator) and FRITZ!X USB?
