RE: Node 0 layout ?

["Nigel Giddings" <nigel@xxxxxxxxxxxxxx>]

Marcus,

If you look at commercial installations they tend to use raised floors
which allow cables to be routed straight up into cabinets. In my last place
of work the raised floor was about 1 metre off the actual floor to allow
for Power, Cat5, Fibre, DC etc. and it was still crowded in there...
However, yo my knowledge no domestic node 0 has a raised floor, yet ?

My advice would be to do what BT used to do, that is install racking / tray
or basket above the equipment and cable down. Of course either way you need
more than 6ft of head room...

I have installed two levels of ceiling mounted cable routes, a lower tray
for Data / RF and DC and a higher level for AC Supply in trunking. This is
in Trunking to help reduce any unwated Electro Magnetic Interferance. AC
power from the tunking is routed down in flexible conduit. The other cables
are just bundled.

I also have a wall where I have located my AC Distribution board for the
house, this is supplied with  75x75 (3"x3") trunking from one
side and along the lower middle. with Traywork feeding in from the top.
Again the idea is to minimise any chance of Mains AC being near DC / Data
Cabling.

Just in case you haven't seen the photos you can see them here..

access to both between Tray and Tunking.

on the subject of node0's....

I'm trying to "plan" where to put trunking for sockets and cat5e
etc..
Does anyone have advice of how to initially layout node 0 ?.. pics ??

The light switch is on the left-hand wall, so I'm thinking of having a
mains
vertical trunk up that wall, which I can then run horizontal spurs off.

Cat5e comes in at ceiling height so I'll run that around all four walls
(like cornice)
and drop vertical spurs off to each device

Does any know a good cheap source of wide trunking.. wide enough to take a
good 400 runs of cat5 ?
