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...

I did try to find out some things on the J1 connector, i messured on a few pins +5 volt between the upper en lowere pins but on all backplanes there are diferences it seems , some pins dont give 5 volt but very low voltage and my meter seems not to handle it , there might be data signal on that...

It could be a mechanical problem as the led`s must transport the light along the drive to the front , they maybe not line up or the leds were to close to the drive and were cracked. i guess you need to messure the leds . Its no powerproblem when all the drives running fine , leds dont really...

I really would really like it if you could investigate the J1 pins , i might get some test too if i can find here a test cable with 8 pin and see what it gives. indeed the I2C header shouldnt do anything as the parts are missing at my 4220 all the populated drivebays have a green glow led ...

After a big job with my 4220 now everything runs fine , i did run into some problems but all fixed, there were lots of disks not detected, but finnaly found out that some SAS connectors are not far enough into the header on the backplanes , they need to go a far way in and it wont go very...

I asked Highpoint about some more info about the led pins on there cards but indeed they keep it secret , not telling more than we can read in the manual ==>Dear Sir or Madam, Sorry for the inconvenience,our product only provide the leds pins not cables,you need to consult the reseller. Here...

tnx Dreamnid for the picture ! it looks there are some posibilitys, maybe also for the unsoldered J4 header. The white 3-pin header exactly looks like an I2C header as i have on my 2740 Highpoint controller , even the text at the pins are the same . so maybe communication can work with this or...

Yes you`re right , most tower coolers wont fit into a 4U case pretty bad that this kind of coolers are not designed for 4U chassis. But there are a few horizontal towers who perform quite well , just very close to the performance of 160 mm desktop towers. Look at Noctua NH-C12P SE14 for...

Well electronic isnt a problem for me, i born with the solder iron lol i know a lot of it , learned myself since i was 13 you can be right , with no load on the pins the voltage can be higher , but i want to be sure what i am doing, as the informations are very less. I dont wanna fry this...

Many tnx Treadstone for your input about the I2C things . my case will come in next week i guess and lets see first how it works with the leds , otherwise there`s maybe some hope to connect homemade leds to the 2740 controller but need info`s about that first which i cant find yet but i keep...

Sure that is a config most people use , one string of molex connectors , but keep in mind that it is limited how much disks you can connect to 1 rail, if its a 22A rail for example and you got 24 disks or something like that you might be run into trouble and need to split all the disks /...

The IC2 thing isnt a standard , but it seems only common for the different brands they all use different ways and pins for this feature. For example my Highpoint 2740 has only a 3-pin connector and the manual says only this : This jumper supports SAF-TE interface (I2C). Pin Number PIN...

Yeh well look for the specs of your PSU that will explain how many rails you have for 12 volt like V1 , V2 ... but some PSU`s have one big 12 volt rail , i think each backplane does only need 1 molex connected , the 2th only when you using 2 PSU`s for redunancy. But its really time Norco...

be carefull if your powersupply has more 12 volt rails , if you going to use more than one molex cable and route to the backplanes they might getting connected by the double molex on the backplanes. i dont know what the effect will be if you do that , the double molex on the backplanes are...

Thats a very bad situation that they sell used or incomplete things, absolutely not good for the name of the reseller. I have a chassis in order but going pick it up personally and check it all before paying, they should accept that , its so havy material that it isnt really a easy job to return...

well done thats a cool setup for sure that way and save , for here i dont do networking normally but play movies and music direct and put it on hdmi to my 7.1 reciever thats going very well , speed enough for single disk setup (jbod) but for downloaden , extacting and copy some more speed will...

indeed its a perfect solution if everything works but i have my thoughts as so much people fighting with bugs with Flexraid specially with foldernames. If sometime Flexraid is a nearly bugfree solution i might be give it a try again, my first try wasnt sucsesfully, had some errors after...

What i am missing is the disk setup for the 10TB raid 5 array, how many disks are involved in that array ? speeds are incredeble

Thanks for your input ! i have concern about the cable lengths i ordered the 50 cm 8087 cables , my raid controller has 2 pairs of connectors, one pair on the end of the card and the other near the slotcover, so maybe 2 cables will be too short, i will ask for it when my order is ready...

How`s your build going ? just wonder how it looks like If you have any pictures would be wonderfull for here , i still have to wait couple weeks , 2th week July the container will come hopefully but now plarnty of time to prepair things , i need to modify my PSU because all of the molex and...

Good choice ! same as me, i cant wait to get the mail that it is arrived. I dont know about the backplanes if the 8087 connectors are situated in the middle or to left or right corner, that would maake a difference in the lenght of the cables. But i think routing can be done under the fanwall...

I see lot of misunderstandings about different styles, it would be good someone who is involved at Norco itself can explain some things here. I actually ordered the 4220 , waiting now for shipping to europe, but what exactly it looks like ? usb in front or not ....i dont know it doesnt mind me...

I use the 2740 16-port controller and doing a good job with the use of single disks , i didnt try raid arrays yet but it is already fast enough for the things i do. It outperforms easy the mainboard controller wit the use of single disks so it does a good job I just ordered the 4220 , 120mm...
