Buildout Plan
Okay, here's what we're doing.
Order of Steps
Installation of hangers
- Chalk a line around the perimeter of the space at 112". - DONE
- Drill 1/4" holes at every 4 feet
- Insert #10-12 Drywall anchors in each hole
- Hang The Loop network cable hangers at each hole, using a #10 sheet metal screw and a #10 flat washer
- Add another pair of hangers at each drop point
Setup of demarcation point
- Extend feet on cabinet so it will stay put - DONE
Installation of cable
- Label cable
- Run cable on floor, leaving enough for the vertical runs
- Lift cable into hangers
- Punch down into punchdown panel in demarc room, mark patch panel
- Punch down into jack at drop point, mark jack with same as patch panel
Preparation steps
- Buy all necessary equipment
- Place all cables 105" (8.75') in the air - this is high enough to clear our loft; and definitely high enough to be out of the way. Hopefully, it's also not so high we can't work on it as need be.
- With the hanger mount point, we'll want to chalk the line at 112" (9'4"). This is high enough to clear the loft as well as leave clearance for the drops
- Place laser level up to draw a line, or use a chalk line to put one on the wall.
- Install all hangers. TIA standards apparently say every 4-5 feet; which should work. Will probably want to double up at drop points.
- Pull cable from demarc to drop.
- Place cable in hanger
- Punch down cable in patch panel and drop
- Rinse, repeat.
Order of drops
My calculations come up that we should be safe with a single 500' pull box, but it's entirely possible we'll come up short. In the interest of reserving funds, I'm opting not to buy the second pull box until we need it.
We will pull in this order:
- 3D printer room
- South wall
- Front door
- North wall
- Woodworking room
Proposed layout
I'd like to get at least two physical drops in every interesting place. Our network backbone and internet link are both pretty narrow (by 2014 standards), which means that it's unlikely we'll see a bottleneck be a small switch attached to a drop point if we need more than the two available.
Limitations of network drops
We have some challenges to overcome when doing these drops.
- Concrete Columns - These columns are wide, and concrete. We can't drill through them to put cables in them, nor easily attach things to them. They're also floor-to-ceiling, so there's no good way around them
- Ceiling - The ceiling, is concrete and 16' up. It's not likely a good place to attach cables.
- Cable visibility - There's no way around this - we're going to see cabling.
Needed equipment
Some way to attach the cable to the wall. Options are:

- http://www.amazon.com/Arlington-TL20-100-Hangers-Communications-100-Pack/dp/B00422M2CG Arlington The Loop hooks (though I'm not sure how these work - I'd like to get an eval item)

They've been historically used in these sort of applications, though.

- Keystone jacks (http://www.amazon.com/gp/product/B0072JVTMA?gclid=CMKG9Kuvhr0CFecWMgodoXAA_w)
- Probably another pullbox (still need to do measurements)

Also, a laser level on a tripod, if we can loan/rent one from somewhere, is going to be very helpful to make sure these cables are hung level.
