I just wanted to get a clarification about connecting the KyroFlux board to power. So making sure I am interpreting it correctly first. Is it powered by the USB connection. So I don't need to power it by the molex connector?
Please see manal for power options. These are only needed when normal setup (drive powered separately) does not work properly. This could be due to problems with ground, or similar.
Apart from such special usage scenarios, KryoFlux is completely bus powered - no further connections required.
Just wondering - (maybe it's in a manual somewhere, but..) - how much current does it need? I'm asking because a) my laptop built-in USB is 1.1 and does not provide 500mA like my desktop comp (and it won't work with, for example, a 3G USB adapter unless I use a Y-cable and plug into both connectors), and b) the extra pcimcia USB-2.0 card for the laptop can only power things like keyboards and USB sticks unless I plug in a separate power supply so that it can provide the full 500mA.mr.vince wrote: Apart from such special usage scenarios, KryoFlux is completely bus powered - no further connections required.
Depending on your revision, you can power the board with +5V (Rev. B) or +7V to +9V (Rev. C) via the DC power in. Alternatively you can connect a PSU to the MOLEX connector on the board. In this case KF will use the power supplied on the +5V rail (Rev. B) or +12V rail (Rev. C; regulated to +5V) of the MOLEX connector.
Be warned that a wrong or damaged PSU might overpower your KryoFlux board. This will void warranty.
Yes, using the molex in on the board should work. Please obeye the last paragraph in the KF manual on page 4 regarding rev. C external +5V power rail selector and make sure it is set as on the photo shown.
Anyway, not a big problem - I can power off Molex, or use my pcmcia USB 2.0 extension card with the optional power supply plugged in, for example. My hardware setup (with 8" and 5 1/4" drives) aren't ready yet so it must wait a bit still.
