i need to bridge it somehow but ramuk you dont recommend me soldering it ?


I am not positive, but I think the replacement would be something like http://www.schurter.ch/wwwsc/con_pg01_2.asp
on line #3 or Line #4

It's time for you to join the rest of us goauld and buy yourself a low wattage soldering iron so you too can burn fingers and other body parts with hot solder and such

By the way, Was it FUSE1 or FUSE2 that was burnt? that would be good for the community to know.

Also, if you remove the fuse, could you please tell us if there are any markings on the back side?


it was Fuse1 same as ramuk's (i only checked this one) and im not sure if remove it or not, if i do i will post if it has marks behind it here. and with this we are two persons who blown the same fuse in the same place just playing with serial, i dont know what this could mean..

i already have a solder (buts a little big) if i decide to bridge i may use it or maybe i ask mu cousin whos good soldering video console modchips to solder a new fuse if i find it.

thank you

I suspect that either in our infinite wisdom, or consumate stupidity (maybe a little bit of both) somehow we managed to short VCC with GND. After all these contacts are right next other,

I ended up desoldering the blown fuse and using a small amount of solder as a bridge, I would not recommend this, but it did work.

I am still trying to positively identify the rating of this fuse: front and back are shown below (the back view has one of the pads detached...

the fuse measures 1.6mm by 3.2mm and is roughly about 1mm thick ... it has no markings on it other than the shown 63 and the small circular indentation on the back side... it is present on both the 5V and 12V rails, each run at 1.5Amps according to the wiki ...

I, too, have met with misfortune and a currently running on a solder bridge, which I am quite worried about continuing to use it without the safety net a fuse provides...

maybe someone from Buffalo or Marvell will know, or perhaps kuroguy?

I would imagine that these are to protect only in case of shorts. They would be high current and voltage fuses. Fuses of this form can take a lot of current to get them to fail. And this sort of current is only available during a supply short. They are used to prevent fires/major damage to PSUs and not to protect the connecting devices.

@lb_worm - any guess as to what acceptable ratings would be?

it's either 5 or 12 v, and 1.5 amps on the PSU, so is there a rule of thumb as to how many times that one would want on the circuit? Would startup require a bit more?

Would something like 15 or 20 V and 2 or 3 amps be sane for this?

after giving the specs of the board/LSPro and the photo of the component to Mouser Electronics, I got a bid back from them with what I hope is a positive ID:

here's the data sheet:
http://www.littelfuse.com/data/en/Data_Sheets/466.pdf


and the catalog/part # from Mouser
576-046601.5NR
MFR PN: 046601.5NR
63V 1.5A
Littelfuse Fuses - Surface Mount
RoHS: COMPLIANT per producer documentation

We will have to test this out and see if it is accurate though.


the good news is that they are only $.46US ... shipping it will probably be 10 times that... :lol:

This is what I would expect to see. As you can see, the fuse has a high current melting point. This is the sort of 'fire' protection fusing you would expect to see in this design. Yes, this fuse will do the job very well.

The only way to test this is to short your supply and ensure that the fuse melts. This is not a good idea as you may still damage other components. All you can do is fit and power up. The fuse will be okay as its melting point is high and it needs a large current demand for a number of cycles before failing. Beware, these are awkard to solder as I really hot iron can damage them. Just solder it quickly.

Right ... I'll avoid the first one ... and try to be speedy about it...

kuroguy - I got that part you sent me - thanks! I am curious at to how badly it will screw up things if I attach it to my LSProV2 ... also, I must scan the daughterboard and find out from you what the 2 extra headers are for ... I know one of them is for serial, but there are two others ... @ CN7 and CN2 ... ?

Any progress on this? (since i'm now part of the fuse-blower show, after meddling around with my usb-serial cable and obviously shorting GND to VCC on the main board :().

sorry to hear of your misfortune :( ...

I actually haven't ordered those parts for trial _still_, but I will do so today, I think...

Do you think it is the same fuse blown? When mine went, it was Fuse 1 that was blown. I am currently still running it with a solder bridge ( I seldom connect the serial to it since I've got a netconsole uboot on it now .)

one is serial. one is GPIO, one is SDI.

Guys,

I managed to blow my fuse too, while trying to build a serial cable out of a phone cable. :? I managed to create a short and sure enough roasted a fuse.

How did the replacement go? I got a quote for those fuses (http://www.littelfuse.com/data/en/Data_Sheets/466.pdf)
to Australia $60 AUD for shipping!! Ouch.

I’m trying to find a local supplier... but so far no luck? Does anyone have any spears they can send me airmail? I would reimburse you accordingly of course? ;)

If anyone knows of an alternative that I might get locally I’m all ears!

Cheers,
Stonie.
