DW6000 Troubleshooting 37
Problem: System LED
not lit
If the System LED is not on, but the Transmit and Receive LEDs are on, there
may be a problem at the NOC. Take the following steps.
• Wait a while. If there is a problem at the NOC, it will soon be corrected and
the System LED will come on. You can then resume normal operation.
• If the LED does not come on after you have waited a while, power cycle the
DW6000 by unplugging the power cord from the wall outlet or surge
protector, waiting ten seconds, and plugging it back in.
• If the problem persists, contact customer support.
Problem: Power LED not
on
If the Power LED is not lit, take the following steps. Note that if the Power LED
is not on, probably no other LEDs will be on or come on.
• Check to make sure the power cable is securely attached. See Figure 24.
• If securing the power cable does not solve the problem, check all cable
connections. Tighten any that seem loose.
• If the Power LED still does not come on continuously, power cycle the
DW6000 by unplugging the power cord from the wall outlet or surge
protector, waiting ten seconds, and plugging it back in.
• If the problem persists, contact customer support.
