Right, that's kind of what I'm left with at present - but that's still me 
power -on'ing SBs, hpost'ing, stopping, replacing DIMMs, and repeat until 
things are clear, which I'd kind of like to avoid.

While the E10k is designed to handle hot swap replacements, I get real 
nervous about powering 20 year old datacentre level gear on and off 
repeatedly. Usually that's when things stop working.

Nevertheless, without better options, that's exactly what I'll do. 
Thankfully I have a bunch of spares from some guy who moved to Belgium. I 
can't remember his name though. (jokes)
