Re: Home Network "Node 0" Refurb, Network Cabinet and Fibre!

Be aware that some fans produce an unbearable rattle if mounted horizontally. I deployed a rack to a client that's almost identical to the one you have, only it was a 14U. It came with a fan that's so noisy I get a call at least once a year warning me that the fan is about to fail. I unplug it for the six months of winter just to reduce the noise in the server room. I'm considering modifying the rack to mount that fan (or a quieter one) in the back or side, vertically. Doing so would also prevent the fan being blocked by people who unthinkingly set things on top of the rack enclosure.

You might consider a smaller fan than is meant to fit in the top opening. The top openings in small racks are invariably too large, probably because they use the same cabinet top that they use for much larger racks with more equipment to be cooled. I would mount it to the side of the cabinet opposite the little doors. Use a bi-metal hole saw to cut the opening and cover it with wire mesh. For a really professional job, use a thermostatic switch between the fan and the mains. Something like this: »www.uk-automation.co.uk/plugin-t···377.html .

Looks very nice...i'm just wondering about this. Are these the proper boxes to use for mains? I see no integrated or external cable clamp on this. Same goes for the IEC to mains...are they rated for such?

Hi

Yes they are what we universally call a dry lining back box, used in almost all new build electrical installations.

They are modular so they can be used for power / data / telecoms or anything else. There are no requirements for cable grips or suchlike in the UK, in fact I have never seen such a back box.

The connectors that were used on the IEC tails are just standard 20A (if I remember correctly) terminal strip and the box that surrounds them is called a choc-box. They are designed to be a more flexible approach to a junction box, and I chose them because they do have cable grips which is useful in this circumstance.

What we normally do is behind the dry lining back boxes we put two cable tacks, facing opposite ways to kind of lock the wire off, but I do not think this is required for code in the UK. I cannot really see the need for a cable grip behind the sockets, surely the wall will be sealed up and probably never touched for a long time? If you open it to make changes you then have an opportunity to check it is still OK?
