19in APC rack

[Jasper Wallace]

Hi,

(This is the collection of large bits of black steel in the workshop)

I might be able to get someone to come and take it away this weekend. If
anyone can think of a reason to keep it, or can get hold of a means of
transporting it to the storage unit this weekend then speak up now to
save it from it's fate, otherwise forever hold your peace.

There are 3 members of the space with Zipvan accounts that i know of,
and probably, a number that i don't know of.

Transportation is not the problem.

What fate is it going to?

Ebay has rack units selling for £400 - £800. You could add it to the
list of things to sell...

I'll list it with this batch then, I'll be making an appeal for transport
later on for moving stuff to the storage (once i know more about what
things need to go).

Aren't we going to need something to put the UPS system in since it's
apparently ex-networking gear? And don't we currently have two separate
wall-mounted rack cabinets around the quite-room entrance?

Is there a reason that the whole lot, including the proposed Borg VM
server, don't go all in this one big cabinet?

I don't know anything about any UPSes being donated (for one thing,
all the UPSes coming through the space have depleted batteries). It's
a big rack, it takes up a lot of space. We don't need a full-sized
rack for 2-3U of server and 4U of networking. Not to mention how long
it'll take to re-terminate all the networking again into yet another
new rack.

There's a relativly nice liebert ups on the quiet room, it's missing it's
rackmounting kit tho.

The liebert came into the space with old batteries - it was alive when delivered but the original batteries died.
There was also an expansion battery case that was unused that came with it - I transplanted 6 of the unused batteries into the UPS so it is almost as good as new.
It never had rack rails but was originally mounted on L-shape shelf rails.

There is room for it in the boxed in power meters where doorbot is.
I t had been proposed earlier to house it there and run three lengths of mains cable to:
 1. The network cabinet
 2. Coolbot
 3. Babbage
to provide clean UPS power to those bits of kit.


I did recently powe rup the UPS to give the batteries a bit of excercise.

[Adrian Godwin]

Coolbot doesn't need much power and the cable run would be awkward. If
it's needed, a small trickle-charged battery would probably do.
Relocating babbage might change the picture.

[Charles Yarnold]

While I'm thankful for the thought for coolbot, if there isn't power for coolbot, there also isn't power for the cutter to heat the water or the chiller to cool it down, so it would just sit there unhappy and powerless to do anything... :-)

[Adrian Godwin]

I think the concern was not so much loss of power, but dirty power,
it's been reported to go a little mad when the welder's used. But I
suspect it's pickup on the thermometer and ethernet leads rather than
mains.

Yes, I think the original thoughts on providing UPS power in the laser cutter area were more for clean power rather more than anything else - possibly not for the laser cutter itself but everything else related to it.


Laser cutter besides - the UPS should still be used for the network infrastructure and babbage (or whatever replaces the services on babbage).
Given that the power draw of any of that equipment is going to be low then the cable run wouldn't need to be of ring main duty but maybe something like a 10A cable.  Then to terminate that cable run with one of the Avocent power strips which includes a load meter and connect the devices to that.
