Power plug for a VAX 4000-300 - test-drb@ccmp.vtda.org

31 May 2007

Hi Zane 
  See previous reply to Tony Duell.
It may be a US right angled kettle lead but its not a UK type.

Kettles here (at least ours does) use standard IEC connectors.

Regards 
Rod

 Yep, it's a right-angle kettle lead; if you've got one that'll work
nicely.

  From what I can
see amongst my VAXen it was only the QBUS machines 
that 
 warranted that sort of power cable; the whole thing was interlocked so

  that if there was a power cable in there you
couldn't do anything 
 other than disconnect. Even when you wanted to remove the PSU you had 
 to make sure there was nothing in the way of the interlocks..... 
If he is talking about the type connector I think he is, it is notched
to prevent plugging a normal cord in.  This is due to it pulling more
amps than most computer cords are rated at.  I'm not sure if this is the
same thing you're talking about, but I think you're talking about
something different.

IIRC, I've seen a couple Compaq or HP servers that use these as well.
