I have a 5200 backhaul that will not boot up. The red power light will come on and nothing else. I tried resetting the unit with a rj11 cable with pins 4 & 6 together on the end of the jumper cable with no luck. I have used the jumper cable to reset other units in the past to factory defaults.
Is there anything else I can do to the unit before sending back?
Thanks,
Michael
