New Infrastructure problems

[vaskotoo]

Hey everyone, I am really glad to see an active and relevant IT forum regarding IT Networks.

I am about to redone the cabling at my new workplace and I face a dilemma problem that I would like to discuss with others that have faced the problem before me. The entire network have 50 users and 30 IP phones.

1. I have in one room 8 wall plates(that I will install soon) with 2 CAT7 cables each, but I need to connect 19 computers and 11 IP phones in that room, here is how I think to proceed and hope there is a better way of doing so.
- I think to use 1 line from each wall plate for IP phones with a LAN Spliter (since they work on 100mb and that requier 4 wires), and after the first direct connected phone to have only one interconnect to ti, so with one Cat7 cable I get out 4 IP phone's.
- The second line on the wall plates to be connected to a switch under the tables (they are 4 spots in the room with tables together) so I will need 4 small switches(that we have). The other way that I think its better is to order a bigger switch with 48 ports and connect everything directly to it, but the thing is that the switch will have to stay in the room, not in the server room, because those cables in the room goes to a patch panel that is IN the room and have connection to the patch panel in the server room
- ? - what do you think about that solution.

2. How to cabling the office room and tables, so I can see as much as less cables possible and they stay in good order and are easier to manage and troubleshoot if needed.
- I am drilling the tables with a hole for cables in one of the corners, my aim is to have 2 Ethernet cables getting out from the table hole on each table.
- I think the switch to be hook up on a place under the table so I can use Velcro ties for the cables and stick them to the legs of the table underneath.
- ? - Power cables , for them I have no considered idea yet, I will be more then happy to hear suggestion.

P.S. I have diagrams but cant see attachment options here.

Im seeing that you are from Germany so I dont expect your english to be perfect, so forgive me in saying that there are a few things I am unsure of in your post.

First of all, it seems you are wanting to do a hub/switch to give additional ports. My initial thought would be that unless you are using power injectors (the device that adds power to the ethernet line) this will not work. POE from a switch needs to be a straight line from the switch to end device, you cannot split that off.

Secondly, CAT7 is overkill and very expensive as well as hard to manage as it is very large, I would suggest unless you absolutely have to go CAT7 you save some budget and go CAT6a (cat6e isnt a real standard, its marketing fluff)

The smalller number of switches gives you less to manage and less points of failure but sometimes you dont have the option so go with what works for you.

As for cable management, there are many options from cable covers that allow you to run it on the ground and have a rubber track over it for protection, to cable trays that screw to tables etc. Please see this link for examples http://www.mockett.com/grommets-wire-management/wire-managers

I hope this answers some of your questions. Again, some of it wasnt quite clear to me so I guessed your meaning. If any of my answers are way off base feel free to clarify and I can try again to answer.

Thanks for the fast respond.

Yes English is far not my native language, please excuse me for that.
I will do a bit of introduction in general plan.
There are 1 patch panel and 10 unknown cables, all cat7 in the server room, the cables are pre-installed before us behind the walls and under the floor.
There is one more patch panel with 20 wires in one of the 2 big rooms, in that big room with the 20 wires patch panel, there are 8 holes with 2 wires each in the room, there are no labels and no wall panels(I am about to install such), beside that the wires on the patch-panel are installed by some "custom standard" or the guy have been color-blind.
Thank you for the answer, the same as I though so I can say we agree on that 😀 .
But in that case with that room, beside the switches under the tables I will also have one next to the patch panel. I have pictures and diagrams I can show, right now, the toner tool come and I am investigating the cables and re-do the patch panels so I can make a proper patch panel diagram for the rooms.
