Q: Integrity Server (rx) power supplies

Hi!

The recent Integrity servers (rx6600, rx3600) use C19/C20 connectors (instead
of the C15/C16 in previous machines) for their power supplies. Unfortunately
when using original HP power cables, these fit quite loosely into the power
supplies. Combined with slight vibrations and a cable management arm in a
crowded rack, the power cords may eventually loose contact.

Does anybody have a solution other than the obvious "HP should profduce better
quality"? I was thinking of some glue to fix the cables to the power
supplies.

Photos of any solutions?

Regards,
Ulrich

you can sometimes loop the powercords once and cable tie them to chassis
openings or fan grills on servers where the cords want to fall out.

Figures - the cords I've been using appear to fit pretty well.
Admittedly a silly question, but I have to ask just to be sure - you
are certain the cords are plugged-in all the way? I had a separate
sitatution recently where I'd thought I'd fully plugged-in a cord of
that type when I actually hadn't.

I'd have to go back into the lab to double-check, but could have sworn
there was a velcro strap of some sort with each power supply one could
wrap around the cord for extra protection against unplanned
unplugging.

Just checked again: They are (in all the way).

You don't have a photo of the final solution, do you?

Nope, but I did have occasion to go into the lab and take a look at a
few rx6600's therein, and there was indeed a velcro strap (black)
attached to the power supply's handle and was then wrapped around the
power cord. On those systems where it wasn't "deployed" it was
wrapped around the handle.

There is a diagram of the back of an rx6600 not far from this:

The handles of which I speak are those diagonal's you see. The setup
guide does not mention the velcro strap It is on enough rx6600's
around here in enough different places that I'm confident the velcro
wasn't an "after market" change.

Sorry for dipping into your conversation, but there are many velcro
solutions at www.speedtechinternational.com.

No, those straps were actually shipped, but already the "solution" with the
diagonal handles is sub-optimal: If those handles would extend vertically
besides the power connector, strapping the power cable would be much easier
than with the "diagonal handle above": The strap would always pull the power
cord's connector upwards, and it's a post-manufacturing solution after all.

So, do the straps not suffice to keep the power connectors properly
engaged?

"It's better than nothing" (TM), but that reminds more more of some cheap
Chinese product than of an HP product (ignoring the fact that the products are
actually manufactured in China). It really seems engineering progress is
running backwards in huge steps.
