Wonder if someone can help me out, I just received my new blade V2 and I also received my backplane I plugged in my power supply and made sure it was the right model number (HP DPS 800GBA) and installed the blade into slot #1 but no lights from the network connection and when I try the ip address nothing. Looks like I plugged the blade in the wrong way, turned it around but still nothing.
Can anyone help me out, Thanks

so you did not follow the drawing on the back(bottom)plane ? you most probably plugged 12V to the ground and vice versa ... does it smell weird ? nothing turned black ?

replace the fuse, you should have received some extra fuses with each blade in a little baggy.

I would contact the person/company you bought them from... ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fwww.bitmit.net%2Fen%2Fimg%2Ftrade_uploads%2F2013%2F09%2F04%2Fnew-v-2-10-7gh-s-blade-bl_38439.jpg&t=665&c=qtms63pTpVcDRA) At the very top-left of this picture, you see a little white SMD fuse right next to the power connection. (Sorry I tried to get a picture without going and taking a picture off my blades, feeling lazy atm....) The fuses are very small, SMT/SMD fuses... look like this: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.newark.com%2Fproductimages%2Ffarnell%2Fstandard%2F42422392.jpg&t=665&c=Wt348DPdO-iJEA)

My blade does not exactly look like that, is it a V2 blade? I think I see what you are talking about it has an "R" imprinted on it and is dark red in color and below that has F1 imprinted on the board.
I sent a message to SSB about fuses included in the box.
Thanks

I thought it was, meh, okay, I stopped being lazy... (ignore the red / white wires, I ran out of yellow / black when I was making that wire longer) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Ftk1337.com%2Fimages%2Fv2fuse.jpg&t=665&c=2YIrl6jCA-2Nhg) I'll be completely honest with you, since my blades came from SSB as well... I almost threw these out, it looked like an empty baggy at first I didn't pay any attention to it almost did toss them. So if you still have the packaging, I suggest you go look through it, as I've ordered a lot from SSB and he's never failed to send something out (to me at least). I already blew one fuse about two weeks ago, of which from the blown fuse, I can't even tell it's blown... just that blade didn't work, was about to make a post then I remembered saving the fuses I almost threw out...

So here is the type of fuse I have: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FZQcsOYZ.jpg&t=665&c=yZ1U39BM81pDKQ) And here it is on the board, does not look like it can be removed: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F2PVBsUI.jpg&t=665&c=s17DfRGVSQblLw) ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FFCu3g5r.jpg&t=665&c=JaQeaPYVZRF-aQ) interesting... did they make a different revision of the v2's?... hmm...

Ok well SSB has not gotten back to me but I think I will buy a power supply and see if that works could be that the backplane is bad.
Thanks for your help

I still find it strange, that we both have "REV 2.01" but they are actually different boards.

Hey I have a new question and maybe you can help
Do you have a backplane and if so what kind of surface did you lay it on, was wondering if I lay it on a metal surface will that short out the backplane.
I am use to putting motherboards on standoffs when I build a new computer rig.
Thanks again for your help

I'm running 4 without a backplane, however, I used Plasticoat and coated the entire inside of an old case just to make sure nothing grounded out. Might help ya ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

That is not true They have SMD R code fuse, 3A, just unsloder old and put new one. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

The blade I just received a week and some ago also doesn't have a socketed fuse, but the "R" labeled device alongside the power connector is indeed a fuse. It's not 3A though, or someone's a fool - these blades are rated to pull at least 7A stock.
I blew the fuse on mine but didn't have any replacements, so I soldered on an automotive fuse in place and it's been working since.
Not sure if these blades are equipped with reverse protection diodes, but it would make sense - basically a diode reverse-biased on the power rails so if you ever plug it in backward it blows the fuse quickly, ideally before reverse voltage has a chance to fry anything important. If that's the case, very likely replacing the fuse (I believe the stock fuse is around 8A, mine blew after 30 hours of handling 11.4A so not sure how much I trust 'em anyway) might bring it back to life.
As for "different" V2.01 models, I think the PCB is the same, just populated slightly differently. Appears that recently they changed the fuse installation, VRM output capacitors and a few other little things - probably to save a few cents per board.
