None of the LEDs Light When the Modem Is On
When you turn on the ZDX, the LED indicators on the front panel should
flash briefly as the modem runs a self-test. If the LEDs do not light, the
modem is probably not receiving power.
•
Make sure the modem’s power switch is on, especially if you normally
turn on the modem by turning on a power strip.
•
If the power supply is plugged into a power strip, make sure the power
strip is plugged in and its power switch is on.
•
Make sure the power supply module is firmly connected to the modem
and to the wall outlet or power strip.
•
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.
•
Test that the outlet is live by plugging a lamp into it.
•
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.
CAUTION: 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.
The Modem Does Not Respond to Commands
•
Make sure the modem is plugged in and turned on. (See “None of the
LEDs Light When the Modem Is On.”)
•
Make sure you are issuing the modem commands from the data
communications software, either manually in terminal mode or
automatically by configuring the software. (You cannot send commands
to the modem from the DOS prompt.)
