This cable uses a momentary switch and a multi-colored white, orange LED. Power Switch momentary function: Black and Yellow wires. I believe that the red and green wires are actually different voltages for each color, white being 5v and orange being 3. A different theory follows a more than common pinout for standard RGB LED strips, where each color is a ground and a stead 5v is applied to the strip rather than to each LED.
Dell does not publish specs for wiring. Its always been proprietary and undocumented. Any wiring diagrams posted on the web are from users, not Dell. SSD drives.Repairing of Desktop SMPS ATX power supply how to basics by innovative ideas
Cakewalk by BandLab and Studio One 4. There are 3 wires going to a Tri color LED. I am not however going to encourage this or provide instructions on how to do this. Others have indicated that the red and yellow wires are shorted together through the switch. I too am a user. Being driven by a desire to expand functionality and mitigate temperature concerns, I have successfully migrated necessary components from a Dell Optiplex DT from its originally case to a full size ATX case that was from the first computer I built years ago!
What I started, thinking it would be a simple task, was tedious, meticulous and potentially hazardous to my equipment. This is for informational purposes only. Use this information at your own risk and ALWAYS confirm everything personally because assumptions are the mother of all mistakes. Moving forward I found information on the web about the 5 wire pinout for the power button and bi-color LED harness with 6 pin connector one cut and used as key.
I found the information at here. A diagram was located at this page. I can confirm that pins 1 and 5 yellow and red are shorted together. Shorting them brings the voltage low enough to cause PSON power supply on. I actually disassembled the power button and used just the interior portion to replace the original green power LED, making sure not to push it in far enough to depress the switch.
This may have just been luck. I accessed the wires by sliding the boot at the end toward the connector and scribed the jacket a couple of inches, then opened it up and pulled out the two wires that I cut, stripped and soldered to the leads going to the new LED. I stuffed everything but the heat shrink covered solder joints back into the jacket, pulled the boot back over the end and taped it all up with electrical tape, letting the new leads hang out.
I simply hot glued the assembly without the metal bracket to the back of the blank plate, after cutting it down to fit. I centered the USB and audio ports on the plate. I must admit, it turned out really clean looking aside from some scratches. I had also originally tried using the single color LED for power but wanted the bi-color for detecting a fault state since I opted not to drill holes for those to shine through. Since voltage was always present going to either leg of the bi-color LED, either power lead caused the power LED to stay illuminated regardless of state.
So I got crafty and managed to squeeze the guts of the power button, which contained all the wire leads and the bi-color LED, into the opening for the original LED.Anyone knows the purpose of five CPU fan pins? I need to connect a non-Dell fan which has four wires. Go to Solution. Dell sometimes swaps the wires around so that you will fry a dell fan on standard and the other way round. I too am a user.

I can't say I wasn't searching, but you saved my day. I have an adapter thats exactly wired like this, but I'm getting a Fan failure error when trying to use my Noctua PWM fans. Any solution for this? If you plugged them in wrong you have fried your fan sensors on the fan and perhaps on the board.

Read times. Dear Forum, I have a Dell Dimension case that I have built into my new iK build, and would like to use the fan in it, but I cannot find pinout information. I can measure resistance if that would help. Wire colors are: white, red, black, blue.
I just made measurements: Connector voltages to common: 5. Thanks Kims, I just sent them an email. It seems they don't list their older products on the website.

Dell 5 pin Fan connector to standard 4 pin PWM Fan specification users reports and reviews
Thread starter Weer Start date Nov 13, Weer New Member. Joined Aug 15, Messages 1, 0. Joined Aug 10, Messages 4, 0. The wires are configured for the Dell motherboards, but the color codes on the wires are standard and the can be rearranged easily.
Let us know if you'd like the pinout set to standard PWM. Jizzler said:. I essentially did the same thing when I switched out fans in my PowerEdge.
Their three-pin fans use an audio style head and I had to switch out the standard three-pin head on my replacement fans with the them. If you have some PWM fans laying around, can use the heads from them, order some, or simply connect individual wires to the pins on the motherboard. Perhaps using a little electrical tape to make sure they don't touch. Joined Oct 29, Messages 2, 0. This can be done without damaging the connectors on the individual wires.
I usually use a pin or thin paperclip.I am planning on a SSD but the motherboard is limited on power connector so I cannot implement it. Then I noticed that there is these above pic pins. What is it for? I couldn't find any manual on the mobo. What I am trying to achieve is to add another SSD onto the motherboard. I have not yet purchase a SSD so it can be in 2. How many drives are in it? Unless you've already got several I'd be amazed if you can't add one.
They have splitters for SATA power, not just molex. Sure seems to be a pinout for a serial port or something. Why can't you use a splitter cable to power the other SSD?
Found this post on Dell forum. Seem to answer my question. Anyhow, thanks for assuring me on the power consumption.
The caddy is definitely an option, but an SSD requires so little power it wouldn't be an issue with a splitter. A splitter would also be cheaper than a caddy. Having seen both cheap caddies and more expensive ones, you'd want the more expensive one.
Thanks for the advises. For the SSD hanging, you can also get some double sided velcro. Your Maintenance Dept might be able to help. Thanks for the tip! I bought the following cables for the next time I hit this issue:.
