<p>Found this RC Groups posting. It looks like a good method of isolating the pins that are involved with powering up the supply. </p>

<div>Thanks Ed - I searched on Google, Bing and eBay to find some specs and didn’t really find anything useful.

<div class=""><br class="">
</div>
<div class="">After posting my earlier request for assistance, I found that the HP DPS-1200FB power supply is used with the ProLiant DL580 server, while the HP Part No: 438203-001 power supply is used with the ProLiant DL180 and DL785 servers.</div>
<div class=""><br class="">

<div class="">I have not yet been able to determine all the ways in which the two power supplies are different, despite their apparent identical power output.</div>

<div class=""> </div>
</div>
</div>
<font size="2" class=""><span class="" style="font-size:10pt">
<div class="PlainText">I have been converting server power supplies for our use for several years. For the last year or so, I have been converting HP DPS-1200FB power supplies. This power supply provides up to 75 amperes at 12 volts and they are about the
size of a paperback book.<span class="Apple-converted-space"> </span><br class="">
<br class="">
Recently, I ran across another HP server power supply. There is no model number on this power supply. Instead, on it is the following: Regulatory Model No: HSTNS-PL11, Generic Part No: 490594-001, Part No: 4382032-001 and Spare Part No: 498152-001. This
power supply is the same size/shape as the DPS-1200FB and is also rated for 75 amperes at 12 volts.<span class="Apple-converted-space"> </span><br class="">
<br class="">
I think it’s strange that HP produced two server power supplies with the same same size/shape and performance. Also curious is that the conversion process required to turn on the two power supplies is different. The only conclusion I can come up with is that
they were designed to be used with different servers, with different “turn on” circuitry.<br class="">
<br class="">
Does anyone have more information about these two server power supplies?<br class="">
