It just doesn't fit as neatly as the OEM connector. It doesn't seem to have any effect on the status of the unit. Some of the - DC outer portion of the size 'L' connector shows out the back of the AEBS. Use a multi-meter to be certain you solder the polarity correctly. On the cable, the CENTER CONDUCTOR is + voltage, while the shield wrapped outer portion of the cable is - voltage from the AEBS power supply. The outer portion of the connector is - voltage. There is not much room to maneuver around in there.ĬENTER HOLE of the cord connector is + voltage. The tabs are small and thin, so don't over-do it with the solder. The solder connectors tend to melt above 700 degrees F, so watch your soldering iron temp. It will not easily accommodate shrink wrap tubing without reaming the cap out a bit. The white DC supply cable on the AEBS Power Supply output barely fits through the plastic cap on the new solder connector. Sure beats turning the power supply into a $20 dog chew toy. Went to the Shack, bought a 3$ bag of size 'L' DC cord ends and soldered one on. Only option was to replace the connector on the end. This makes repairing the cable impossible. Our dog chewed the cord of our AEBS, right at the DC connector end. Note: The older Airport Extreme units take a 5.1 volt power supply, so, if you have one of those (it will be marked on the power supply and Airport Extreme cases), you CANNOT use a 12 volt power supply.Īirport extreme cord connector repair - Thanks! I am posting this as a solution and workaround in case your 12 volt power supply dies and you don't want to spend $50 dollars for a new one that also will likely die. I plugged it into the Airport Extreme, the light came on and it worked like a charm. This completed construction of the new power supply. Then, being observant of polarity, I connected the wire going to the center of the power plug to the positive (+) terminal on the power supply and the wire going to the outer ring to the negative (-) terminal on the power supply (hooking them up correctly is critically important!!). I then used some speaker cable and soldered the speaker wires onto the new connector. Then I went to Radio Shack and bought Size L Coaxial DC Power Plugs (you only need one, but they are sold in pairs). I found one rated at 1.75 amps (close enough to the required 1.8 amps and a lot more than the 1 amp of the Apple power supply). (Perhaps this was an Apple-planned equipment self destruction and, besides, any new one would also be rated at only 1 amp and be destined for destruction by overload).īeing a ham radio operator, I have a few Radio Shack 12 volt power supplies I've picked up at swap meets for a few dollars each. However, the supplied Apple power supply was only rated for 1 amp. According to the cover on Airport Extreme, it requires 12 volts at 1.8 amps. After finding that the replacement cost is about $50 and seeing that the old unit is sealed for eternity preventing access for repair, I decided to see if an easy, inexpensive substitute could be made. The power supply on my Airport Extreme died on me today.
