Power LED is Off
External power supply has failed or is disconnected.
•
Check connections between the RoamAbout R1, the
external power supply, and the wall outlet.
•
If the power indicator does not turn on when the
power cord is plugged in, you may have a problem
with the power outlet, power cord, or external power
supply.
However, if the unit powers off after running for a while,
check for loose power connections, power losses or
surges at the power outlet.
If you still cannot isolate the problem, then the external
power supply may be defective. In this case, contact
Enterasys Networks Technical Support for assistance.
