Cable just doesnt seen to work.
Posted on 2006-05-31
Ok currently I am cabling a resort in puerto rico. Here is the setup:
DHCP SERVER ---(10 feet, CAT5)---- DLINK FAST ETHERNET SWITCH(#1) ----(200 feet(CAT5)-- NETGEAR SWITCH (#2) -----(100 feetCAT5)--- DLINK FAST ETHERNET SWITCH (#3) ----- (100 feet CAT5) ------ NETGEAR HUB 10/100Mbps
ok on the netgear hub i got connected 1 device and it works fine, that device is at about 50 feet distance.
I can connect other computers and switch ports and it all works fine.
The problem lies when i try to run a 120 feet cat5e wire. It doesnt get signal, for some weird reason. I tried using a cable tester that check continuity on all 8 wires and they are setup fine and look fine(no shorts and no broken wires). I have the equipment connected to a normal port and the wires are straight thru(no crossover or patch, all wires straight).
I also played around changing the ports and they all work fine. I am starting to believe that it has to be the length, but isnt CAT5 rated for 100 meters (328 feet)?? I am using the same laptop to test all cables, so the laptop is configured right.
Is there any other test I need to do to the wire?? I would believe continuity is enough because it is just 8 copper pairs. I only untwisted 1/2-3/4 inch of the wires pairs so i could put it on the RJ45 connectors, so basically the wires are made to specs. I replaced the jack multiple times and cut some more wire just to make sure it wasnt the jacks or parts of the ends of the wires.
I am really lost here, maybe there is something I am not seeing. Been checking this all day and need to have it fixed before friday. Throwing the wire again is the last option because it has been a pain to pass the wires thru a lot of pvc pipping slowly as to not break it and it took over 6 hours to get it in(2 pairs witha phone line going thru a 1/2 inch pvc pipe.
Forgot to mention that wireless is not an option as we are running a system called MICROS for restaurant and hotels and it doesnt like wireless at all. The latency caused by wireless is a no no for micros.
