2.7 Troubleshooting
Your MultiModemZDXV was thoroughly tested at the factory before it was
shipped. If you are unable to make a successful connection or if you experience
data loss or garbled characters during your connection, it is possible that the
modem is defective. However, it is more likely that the source of your problem
lies elsewhere. Problems you may encounter include:
•
None of the LEDs light when the modem is on;
•
The modem does not respond to commands;
•
The modem dials but is unable to make a connection;
•
The modem disconnects while online;
•
The modem cannot connect when answering;
•
Slow file transfer;
•
Losing data;or
•
Garbage characters on the monitor
2.7.1 None of the LEDs Light When the
Modem Is On
When you turn on the MultiModemZDXV, the LED indicators on the front panel
should flash briefly as the modem runs a self-test. If the LEDs remain off, the
modem is probably not receiving power.
4
Make sure the modem’s power switch is on, especially if you normally turn
on the modem by turning on a power strip.
4
If the power supply is plugged into a power strip, make sure the power
strip is plugged in, and its power switch is on.
4
Make sure the power supply module is firmly connected to the modem and
to the wall outlet or power strip.
4
If the power strip is on and the modem switch is on, try moving the modem
power supply to another outlet on the power strip.
4
Test the outlet is live by plugging a lamp into it.
4
The modem or power supply may be defective. If you have another Multi-
Tech modem, try swapping modems. If the problem goes away, the first
modem or power supply may be defective. Call Tech Support for
assistance.
*
:
Do not under any circumstances replace the power supply module with one
designed for another product, as it may damage the modem and void your
warranty.
