ISO: DECServer 550 Power Cord
In another case of, "the right way, the wrong way, and the DEC way," it seems there's a special IEC cable used for DECServer 550s. Does anyone have one? It looks like a regular grounded IEC cable, but with a groove cut in the plug, opposite the ground pin. Looks like I could probably make do with a Dremel tool and a standard cable, but I thought I'd check first. Thanks, Jonathan
Google c15 connector - if that's what you need I can drop off Saturday am with the rack side panels

Its actually standard, the high temperature version of the normal IEC connector. It is rated to 120 degrees Celsius rather that 70 as the normal lead.... .. in the UK we call them Kettle Leads as they are commonly used on kettles... https://en.wikipedia.org/wiki/IEC_60320 Dave G4UGM

I've seen those cables on older large HP servers. I'm sure other stuff uses them as well. In a pinch you can modify a standard cable. Take care that the cable can handle the power though! -J On Thu, Oct 6, 2016 at 3:14 PM, Dave Wade via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

...and the right way that one doesn't understand, and thus assumes was a bad idea. ;) *poke* They're standard IEC320-C15 connectors, which are the high-temperature version of the very common (without the notch) IEC320-C13. Large Cisco switches and routers, as well as some SGI equipment (Origin 2000 comes to mind) use the next size up, the 20A-rated IEC320-C20. These are all IEC-standard connectors. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Replying to myself in bad form, I should also have mentioned that many mid-sized Cisco devices also use IEC320-C15 connectors. If you have a friend who works in a Cisco-heavy environment, he/she may have some to spare. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Also, percolators. Mine came with such a cord, though the socket on the pot doesn't enforce it. The high-temp cords don't melt/deform at high temperatures, which is a serious safety concern for servers and coffee pots. - Dave
Thanks for the replies, everyone! I'll find one on eBay. So, what's this special high-temp connector doing on a machine with a 340 Watt power supply? Thanks, Jonathan

eBay?! Try: https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywo...

If it's designed to be in a densely-packed rack with lots of other things with possibly restricted airflow, it's a genuine concern. Just remember, this is high-TEMP, not high-CURRENT; it's not a 20-amp plug, it's just designed to plug into things that potentially get quite warm (such as coffeepots/tea kettles/densely-racked computer equipment). - Dave

Cheaper from the same item (probably go with the Tripp-Lite, I hate cheap cords) through eBay, plus I've got a PayPal balance at the moment.

I understand that, but this is a freestanding SBox machine and the plug is at the bottom of what appears to be a well-ventillated assembly. I don't know if the power supply is applicable to other, denser chassis arrangements. I would think that, if airflow were limited enough to allow the IEC plug get warm, the QBus cards in the chassis would be out of their operating range anyway. Of course, I haven't looked at the actual specs for C15 socket/plug, or SBox cards, I'm sure someone can provide a theoretical situation where it would matter :P Thanks, Jonathan
Remember, the BA440 chassis is rack-mountable. Not all of them are in those free-standing shrouds with the floor stand. -Dave -- Dave McGuire, AK4HZ New Kensington, PA On October 6, 2016 7:15:04 PM Systems Glitch via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
