Its indeed a very difficult modification , not only one part to change but several more and that on all backplanes... it really need the right tools , i soldering over 25 years now but i haven`t done much with SMD parts , i did modificate some cpu`s that was a difficult job to and lots of risk...

You`ve done hard work on it ! well i will see if i can get some parts like transistors and resistors seems like 49,9 ohm type http://nl.farnell.com/panasonic/era3aeb49r9v/resistor-49r9-0603-0-1-0-1w/dp/1809605 and the gate ...

hmm project seems on a death path, i dont have more ideas if anyone can could do some input .... I actually google around to find a way to blink led outputs by command as some professional applications have the option to localize the server/ drive which is in error or needed maintenance but...

Just wonder have you been able to fix the resistors voor de bleu activity leds on the backplanes ? i dont know how far to go with it cant messure things on that. Need to put out all the backplanes and thats a big job with all the cables lol . For the error leds i maybe have another idea ...

indeed so such a thing as the HC 14 should be posible to add on a pcb for me its maybe best way to cut the circuit between the red led cathode and the 470R resistor , and take the led pin with wire to my controller via a resistor , if the red led is powered by + 3,3 volt on the anode on the...

indeed option 1 wont work with the backplanes it seems even while the SAS cables has the wiring for it . option 2 lost as well so left is 3 , and try to use the led headers on the controller for it i really think that many controllers work with negative output , so we need to change the...

Many tnx Threadstone for the good work ! i have been busy with it and i could light up the red led by put the pin 8 via 4k7 resistor to + 5 volt but i couldnt get the negative input work my controller seems to have negative output as my homemade leds for the data activity are working well as...

Seems Norco use some different types for the 80mm fans on fanwal for peeps who interested in the specs ;

Update; i put the leds into the front , very easy to take off the front panel thats make the work easyer.

I know the SAS cables are hard to bent i have one its nearly too short to reach the controller , i cut of shrink for the first 10 cm near the connectors and on that way they are much more flexible , with some care it wont hurt the cable.

Indeed the Norco fans should be far over 31db i read wrong somewere i guess but for redunant powersupplys be prepair they using 40mm yetengines they most worse ! i have had an 1U chassis that have 40mm Delta fans ... this makes it not usable into home areas.

hmm i dont know if you get things clear but redunant PSU are 2 or more units but they are smaller , they would fit into a standard ATX space but need another bracket to fix them to the case. Than you can use from both PSU`s molex 4 pin cabels to the backplanes and than they are powered double...

my Norco has origional Delta fans 3000 RPM 31dB , the AFB0812H they really loud so i think you maybe have other fans ?

i guess you can just use a 120 fan wall , the chassis 470 , 4220 , 4224 are just about the same , it might be nessasairy to just dril a couple holes if they are not alined but i think this is no havy job. Also its easy to modify the wall itself , cutting extra holes if you need to. I using now...

i am using the Noctua NH-C12P SE14 right now into the Norco 4220 and works very well its just leaves a few mm space from the PSU but the PSU has there the airinput with fan so i guess it wont be a problem , other mainboards might be having another layout that leaves a bit more space free...
