Title: Cat5 Booster thing?
Post by: chrisdicko on July 22, 2013, 15:34:26 PM
Can you get something like a Cat5/RJ45 booster/repeater type thing?

I'm thinking of something which looks like a switch, but one input has one output, and the unit is powered?

Just at work, they require a PC/printer/phone etc moving, and the 4 cables won't be long enough, so would need re-doing which is a real pain to be honest, so it would be easier to pull the existing cables back, then use the booster as a connection point, and then run 4 new cables to the new area.

Also, another reason for the booster is one of the PC's (in a different area) is probably on the limit for the cat5 range. I'm not sure of the exact length, but it is around 100m, and seems to get random network errors, even though the cable tests ok. So I'm hoping a booster may help with this issue as well.

So can you get a booster type thing, with 10/12/14 ports on it? Powering it won't be an issue.




Cheers :)

a switch will act as a repeater. Just add a little extra latency. could alway put a switch at their current location & new location & join with Fibre if speed is critical over cost.

No, speed isn't really an issue.

I have very little knowledge of stuff like this, so this may sound dumb, but.........doesn't a switch have one input and many output? We'd need something with a minimum of 4 inputs and 4 outputs.
It wouldn't work with one input, as there are phones, louder ringers, a PC and a networked printer on there.

a switch is just a group of ports that transfer the data around, its exactly like a router without the modem attached, so you simply plug in all the cables and let the devices talk to one another.

so for a 4 in 4 out you would need an 8 port switch.

What these guys are saying is correct, I assume you have power at the point you want to install the switch/repeater also, if not you'll need to use PoE (Power over Ethernet).

However considering you are only looking to move a PC/Printer/phone, I'd just run one cable and drop another switch at the end and run the computers off of that? rather than running 4 lengths.

The only downside to this is that you would be limited by the switch speed on a single port, so 100Mbit or 1Gbit depending on your network, but even 100Mbit should be sufficient.

Cheers for the replies guys :) I thought a switch worked with one input (from a server), then had 8 outputs you could run 8 computers off.

XEntity, we were also going to use the switch as a booster for a few other PC's which are probably on the limit of the CAT5 cable length.

I've done a quick pic of how I think the switch works. How does it know to match each cable to which? I.e. Why doesn't the phone cable get swapped with the pc cable etc?

If the above is correct, I imagine it would be worth getting say a 16 port switch to run another two pc's and another two phones though?
Title: Re: Cat5 Booster thing?

no....

you just need 1 cable going in from your network, and then plug the other stuff into it (pc, printer, phone, etc. etc.)


but... the 4 cables you have coming in now... where do they come from ? are they just plugged into a normal network switch ?
(they should be... just need to check in case you have something weird going on, like a separate system for the phones etc...)


so.. you can use as many switches as you like, and plug whatever you like into them, in any port... and everything connected, can talk to everything else which is connected, all at the same time :-)

Yeah Alan is right sorry, I thought you were trying to double up cable length for each device by using the switch as a makeshift extension. You wouldn't need 1 in and 1 out for each, just one going back to the main router/switch and the others all connected to the switch.
Title: Re: Cat5 Booster thing?
Post by: chrisdicko on July 22, 2013, 22:58:01 PM
I'm nothing to do with the IT Dept. (we don't officially have one), so aren't 100%.

I do know the phones have their own system though, so I don't think a switch will work in that sense then. And the printers seem to be set up that you can use any printer on the network.

So to keep the cables on their own, can you get booster/joiner boxes, which look like switches, but have say, 8 inputs, and 8 outputs?
Title: Re: Cat5 Booster thing?
Post by: knighty on July 23, 2013, 01:36:38 AM
you just need to check where the cables for the phone etc.. go to... chances are they'll just be going back into another switch like the picture you posted above

I've never seen anything like a booster... they probably exist... but if you can see where the other end of these cables is plugged into, and you can use a switch instead, then they'll be a much better system

it's not abnormal to have multiple cables installed when 1 cable and a switch would have done, I've seen it loads of times (mostly noticed it because it's the wrong way to do it) - mostly installed by IT companies who use it as an excuse to charge more!

get an ethernet coupler - about £7 in maplins - £2 on ebay. - Its possible to join 2x 100m cables with a coupler in theory (never seen it used for cables of that length)

join 1 cable with coupler & run to new destination.
Move the printer to the new destination & plug in this cable.
Can you ping the printer? can you print? yes? yes? then extend all other cables with couplers.
No? no? coupler wont work, replace with Switch at both ends & use the cable you ran to join the switches.

Use the same cable run for the phone - I would guess a phone (assuming its an analog system) can easily be extended & dont have as many limitations as ethernet

The cables all go to our 'Server', which are made off with a tool, rather than plugged in, then a short cat5 cable plugs in to that, then goes to something more inside the server.

The guy who sort of looks after IT said the phones can't share cat5, as they are not IP intelligent.


Joiners/Couplers may be the way to go then.......
Title: Re: Cat5 Booster thing?
Post by: XEntity on July 23, 2013, 20:11:04 PM
Joiners won't boost the signal though, however are the phones IP phones or are they regular phones using a cat5 patch panel? If the latter you don't want to use a switch, and you may be ok using a coupler, couplers are cheap so worth a go.

If they are IP phones then I'd suggest noting the IP addresses of the phones and the computers and seeing if they are in the same IP range or subnet?
Title: Re: Cat5 Booster thing?
Post by: XEntity on July 23, 2013, 20:14:18 PM
Also I'm sure I picked up a pack of 10 couplers for about £2 don't get ripped off at maplin for a bit of plastic with a bit of wire!!

can you get some photos ?

sounds like the phone needs a coupler/joiner

and the rest just a switch in the new office with a single extension out to it

Thats the easiest & most logical way.
Extend the phone cable.
extend one data cable & put a switch on the end.

see, i so nearly wrote these two simple replies last night myself. along with an added dash of "if your IT guy hasn't already suggested this then show him the door, he's crap".

but i decided that was too negative and ive got to be more positive.



meh.

Post by: chrisdicko on July 24, 2013, 20:10:45 PM
We don't have an IT Dept :) Just one guy who half looks after it, but he's is an accountant. It's use maintenance boys who run in the cables, and make off the ends.

Hence zero knowledge :)

I couldn't get any photo's as I wasn't in today, but I've ordered some couplers, so will give them a go. The phones use Cat5 cable too, not normal phone cable. I'll use the couplers where the computer and phone currently is, and see if they work ok with extended cables. If so, we'll pull them back, use the couplers, then run new lengths to the new area.



Cheers :)

100mtrs is pretty long, think its max length of cat5e for 100mbit operation.

If you get network errors try dropping the speed to 10mbit, or upgrading to cat6.

& re terminate the cable

Im suprised a pair of home plugs have not been suggested :D

Post by: chrisdicko on July 25, 2013, 17:47:43 PM
My computer and the engineering managers computer are probably the furthest away from the server, and we randomly get network errors actually! How do you drop from 100mbit to 10mbit?
Title: Re: Cat5 Booster thing?
Post by: Clock'd 0Ne on July 25, 2013, 17:56:40 PM
You change the adapter settings in device manager, look under Advanced or a Link Speed tab in the devices settings.
Title: Re: Cat5 Booster thing?
Post by: chrisdicko on July 25, 2013, 18:00:29 PM
Brilliant, thanks :)

We built a new office quite a distance from the server, and the IT contractors use optic to get to there then another switch/server thing, but even then, that new office is too far away from us :(
Title: Re: Cat5 Booster thing?
Post by: bytejunkie on July 25, 2013, 19:45:38 PM
then you need another piece of fibre and another switch near yours and your managers desk.

its simple.
Title: Re: Cat5 Booster thing?
Post by: chrisdicko on July 25, 2013, 19:58:11 PM
That's beyond us to be honest! I doubt they'll pay for a contractor to do it either.

i despair of companies that wont pony up a few hundred quid to get sh*t like this sorted. i don't know why but i always end up working with them. current employer is paying me a fortune for the actual workload they're asking me to do (a different rant altogether) but i came in for some 3rd line/build config for san and citrix work and they give me a 4 year old laptop to use.

just pay someone to come in and sort it. it'd be done already!!!

Post by: chrisdicko on July 26, 2013, 07:28:50 AM
haha, if IT fell under the engineering department, it would have been done! But, for some reason, the "IT dept" is under the control of finances....hence no spend  :lol:

same story where i am right now!!!i even asked how it affected IT spends, when the person signing them off was finance director and therefore tasked with saving the company money at the interview.

10Mbps and 100Mbps are both pushing boundaries at 100m+. You will get issues with timing.

You could get two tin cans and a piece of string.

Option 1:
[Comms cabinet in server room]---------fibre link-------[comms cabinet 2]

Option 2:
[Comms cabinet in server room]---------100m CAT5 STP link-------[comms cabinet 2]


Option 3:
[Something else and everyone says what a muppet you are for recommending it]/

Egg answered the question in the first reply tbh.

I bought some couplers from RS and used them. They worked fine :)

Although mine and the other guys PC still seems to time out/give connection errors, even though testing the cable is fine. Probably because of the 100m+ cable run though....
