None of the Indicators Light

When you turn on the modem, the 56 indicator and the terminal turn on. If the LEDs
remain off, the modem is probably not receiving power.
CAUTION: Do not under any circumstances replace the transformer module with
one designed for another product; doing so can damage the modem and void your
warranty.
Make sure the modem's power switch is on, especially if you normally turn the
modem on by turning on a power strip.
If the modem is plugged into a power strip, make sure the power strip is
plugged in and its power switch is on.
Make sure the transformer 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 transformer
module to another outlet on the power strip.
Test that the outlet is live by plugging another device, such as a lamp, into it.
The modem or the DC power transformer may be defective. If you have another
Multi-Tech modem, try swapping modems. If the problem goes away, the first
modem or the DC power transformer may be defective. Call Technical Support
for assistance.
