Any clover or kettle lead will do. Cut the end off (not the one + that goes in the wall, but the kettle/clover connector). + Strip the protection away by a decent length, then strip the wires inside so that a decent amount of + copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in + and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job + could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up + the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure + that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device + says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device + says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots) + around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in). + </p> + <p> + Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or + 1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>. + </p> + <p> + Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this: + <a href="images/x200/psu_screws_removed.jpg">images/x200/psu_screws_removed.jpg</a>. Then, + </p> + <p> + Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the + screws each, around it near the head. I then screwed them in: + <a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>. + </p> + <p> + If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied, + continue reading... + </p> + <h2>Setting up the BBB</h2> + <p> + Your BBB will have an sshd with no password on root. Find it's IP address + (it will use DHCP by default) and set a root password. The steps below + are done while SSH'd into a BBB. + </p> + <p> + Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded. + <a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you + from causing any ESD damage. The surface that you place components on should also be earthed/grounded. + (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal + part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>). + Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB + in a shielded anti-static bag when you are finished with it. + (the principles above apply to any computer components, since they are extremely sensitive te ESD). + </p> + <p> + These instructions may or may not work for you.
