fore es-2810 PSU

[yonu]

anyone happen to have any idea if a standard at PSU can be used in a fore Ethernet switch my psu bit the dust at least i hope it is the psu and I need to test it

Re: fore es-2810 PSU

if they use 12v, 5v, or 3.3v, then a computer psu will work just fine. You would just have to wire it all up and wire a switch to the power_on to a negative on the main 20/24pin connector for a switch.

Re: fore es-2810 PSU

You might have issues with not enough load to keep PSU on.

Re: fore es-2810 PSU

not atx i actually mean AT as they are at connectors on the switch

Re: fore es-2810 PSU

Hmmm, you would have to check the pinout.

I have a old upgrading and repairing pc's 5th edition around here with the pinout for a at power supply's connectors.

Also, those older power supplies would usually fry themselves without a minimum load on each voltage.

Re: fore es-2810 PSU

ok guess i will start looking for a nerw switch

Re: fore es-2810 PSU

AT has:
+12v = Yellow Wire
+5v = Red Wires
-5v = White Wire
-12v = Blue Wire
-- some also have [rare]
+3.3v = Green Wire
.....
Do not use Orange wire for power. That one just tells a mobo that PSU is ready.
.....

Most AT PSUs probably don't care about minimum loads like ATX units do.

Re: fore es-2810 PSU

Those with +3.3v will have three 6 pin main power connectors vice just the usual two.

I think they care more about minimum loads. According to upgrading and repairing pc's 5th edition, almost all do need a minimum load, and only higher end astecs and pc power and coolings had a minimum load built into them for bench testing.

Re: fore es-2810 PSU

thanks guess i will hope for the best and try it weith an old at supply at least then i will know if it is the switch or the psu

Re: fore es-2810 PSU

well I finally got around to sesting the switch it is something in the switch i hooked up a normal at power supply if i hook up only half of the connector the fans turn on if i hook up the whole thing nothing comes on so i suppose the switch just crapped out

As I recall most AT PSU's will kick on with nothing connected at all.

Re: fore es-2810 PSU

All I know is that IBM would put little resistors in place of hard drives in thier early systems to put a minimum load on the psu. I've had countless deers and other gutless wonders as well as new antecs and a supermicro that have no problem running with nothing attached.

I fried a old lite-on AT psu because it had no minimum load and when I jumpered it it just ran for a second then *pop*.

Re: fore es-2810 PSU

Probably had a load resistor but not big enough.
