should I use a switch or run another drop?

Hello Experts,

I am brand new to Administering a network.  Here is my situation....

My work is installing a new piece of equipment that is located about 120' from one the main unmanaged switches on our network.  I have one Cat6 network cable that is about 20 feet short from where it needs to reach.  My though was to attach a netgear gs105 switch at this point and then run a cable from one of the outs to the new workstation.  I was told tonight that this may slow down the network... is this true?  Should I just buy some more cat6 and string it from the main switch all the way to the workstation?

Our network setup currently involves about 40 workstations -> 3 unmanaged switches -> 3 servers

Any help or guidance you can give me would be great.... I am just beginning to learn the world of networking

Thanks

The more hardware you have in a network environment, the more steps you have to go through to troubleshoot problems later on.  I would personally just run a new line.  This would be the cleanest suggestion.

If you can't see through your rear view mirror in your car do you adjust the mirror, or do you move the seat?

There are a couple of ways to do it.  Full specs say you'd run a new cable, but if you're careful you can splice on some more CAT6 using twisted pair connectors (mostly used by phone people, little crimp down splicers filled with liquid) and then shrink wrap the splice.  A switch won't necessarily slow down the network, but it's not the optimal solution (another possible point of failure).

You could also terminate the cable where it is and run a 20' long patch cable to the device as well.

i agree with jingram82. the more hardware you have, the more you have to troubleshoot. if possible keep everything in a centralized location

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Thanks for your help on this matter.  No i just feel like an idiot for not just running the cable. :)  Oh well, I still have time to get it done.

Thanks again

No need feeling like an idiot, better to ask and get verified.  From your original post it sounded like that was your decision anyway.

Assuming you ran a 100' patch cable, you could purchase an inline coupler and continue the next 20 feet with another patch cable.

you could also jsut buy one of them cabel extenders.. basicaly a small plastic with a j45 socket in both ends.. you get a simller thing for phone lines..

and for a single run of cabeling they seem to work fine.. i have a few laying around and never had problems.

Thanks again for your help,
For now I have no choice but to use a switch to support 2 new workstations.  I am going to schedule running more drops during downtime of production.  I should be OK with a switch in the your term yes?

Thanks

Can adding to many switches slow down a network? or is it more of an issue of ease of troubleshooting?  Fewer switches = less headache?

cbmmCommented:
wont slow it down. the only problem i see is actual throughput. if you run a gigabit connection between the switches you should be good, but if you are running 12 pcs off a remote switch and a 100mb connection you might run into some problems. think about it, 1 data cable interconnecting switches that has to be shared with how many pc's you have running of that switch.

ok,  just wanted to make sure.  I want to do everything the best way possible but at the moment I am facing a time crunch.

more managment

moden switches can switch data around the network with almost no delay.. we are talking micro seconds!! (100 of a mill second)

so its only once you start having 100's of switchs (in a row not in the network as total) that a packet needs to pass through that you would see any effect on the network. and even then you would be talking about a 1ms delay.

so really a moden switch does not introduce any meaning full delay in to a network... and i dont know any one who runs packets though more than about 10 switchs in series any way. espicaly in a good star/mesh topology.

you might want to read this about how switches forward packets.. by default most use cut through.. with this a switch will alreay be forwarding the start of a packet before it finishes reciving the end of it.. THAT is fast ;) !!

This is the one I am using, which uses the store and forward method. But still seems fast to me...... walking into managing a Network as a newbie certainly is a humbling experience. :):):)

i walked in to this job a few years back having never seen any thing more impressive than a 4 port home router!!

now i have over 120 corprate switches at my finger tips ;)

your lucky you will get to learn as you go along and your network grows.. i still getting my head round it. love it though :)

Well Future did only last post on this on thursday, so i'm sure he hasn't abanded it yet, and i'm quite happy to comment on a few more of his questions before it gets closed?
But i think we all agree the original question got answered on weather to use a switch or run a longer cable..

Future you need to chose a person (or persons) who gave you the ansewer and give out the points. you can choses multiply answers in one of teh comments and choses more than one person to split points accross if you like.

or if you dont feel it was answered you can just ask it to be closed.

good luck with the network :)
