External power supply - Cisco ADP-30RB

NEW REVISED EDITION.
I got sick of the thick heavy unwieldy cisco cable that is just ugly...!! So here is the new improved method.











Cut off the fat ugly cable. But leave    Remove the rubber feet at the        Just cut the cables short except      It is easier to unsolder them short.
the protector.. we can reuse it.          power end and remove screws        ROF which can be soldered in        Just grab with pliers. ...











Unsolder from the back side..             With a lot of care..                         Pass the new cable through.            Solder it to the points.

















I then used some cable fittings            Remove the wrapping from             Cut through the goop with a             Unsolder them.. Clean off goop.
Use what you have or just tin the        old power supply,, short the            small screwdriver.                           Tie 5v &Gnd before cut and reterminate
wire ends if you like.                         main caps carefully.                                                                                   if you don't want to unsolder.  











Solder on extensions.. up to you        Use a piece of terminal strip.        Ensure voltages are correct.. well before of course.
Easy to know voltages..
5wires =Gnd.. 4wires=5v 1wire =12v
















To make it absolutely clear.. here is the board shot with correctly color coded plugs.
Standard computer code.. Red 5v.. Yellow 12v.. Black.. Gnd.
The wires can twist up.. please check sata power pinout if unclear. In its correct position, 12v gnd 5v gnd
If you cut the wires from the original supply wrap red tap around the bundle of 4 wires before you cut.
Wrap black tape around the bundle of 5wires before you cut. It makes it easier than sorting out 10 black wires after the event.





For those who would like I can do this as a kit.. a power supply suitably modified.. and the plugs as removed from original supply.. but you need to supply me your old dead power supply for me to recover those plugs.. I can and have used a standard sata power and a standard inline pin socket.. but not as neat as the originals. Soldering the pin socket and insulating it is not easy.. I have also ashamed to say, directly soldered the wires to the board.
(Why the hell did Apple build this thing with plugs and sockets when they claim it is unrepairable.. Why the hell not supply a new power supply?? Sorry; end rant!!)

The kit will have all the above done for you.. Just put the cable through the TC power supply port.. and screw up the terminals.
I will give some indication of the correct colour coding. But I try to be logical.. ie using a 6 wire cable.. I used Black, Green and Blue for GND.. Red and White for 5v and yellow for 12v.. Try and match something that makes sense to you.. and of course write it down somewhere. Don't wire things to the wrong voltages.. and test test test,, before you finally connect things up.
BTW find some nice white sheathed cable.. you can get security cable which I have used here, white cat5 cable is also fine, or a thin 3 core power cable. Anything you like really but using white makes it disappear in the all white TC.. but you can use whatever colour you prefer.

If you want an external plug and socket you can buy an inline molex.. but I find them unnecessary and if something goes wrong it isn't hard to replace the Cisco supply with the connector strip inside.
Don't worry about the fan.. you can even leave it out. Use a cable tie to hold the molex to the steel frame.. and you will need to carefully bend the power cable to avoid the fan if you leave it in.

I am still looking for a better external plug and socket combo... and sure open to suggestions...when you look at all the NAS boxes etc they tend to use a mini-din type connector.. ps2/etc. They are IMO, fragile and the sockets are hard to get and still too large. Also for 3A the pins are too small.
