Network question

Working ona side job, and something make me pause and think for a moment. The job is for a dentist office. Can the X-ray machines interfere with LAN, Phone, or CATV at all?

Thanks, and poop on you all!!!

Up your Focking Arse, Noob!

Oh wait. Sorry Jef.



Ask Riser, he's the network professional around here who actually has a job as a network analyst which means he spends his arse on here all day typing to dead-shites like you and I.

Hey, look at that, I did a triple winky. Special!

Even threw in a Mac special for you on the end there; you dig>? :lol: 8) 8) 8) 8) 8) 8) 8) 8) 8)

The 1700's. He's making muskets like a motherf*cker to prepare for the big one.

Which is the higher concern the affect one the medical equipment from the networking equipment or the networking equipment being affected my th medical? Chicken or egg?

not sure but i think it is different between shielded and unshielded...

STP cabling is the way to go here. Stay away from wireless.

I don't know about LV being subject to inspection there, but around here it isn't. Been 2 years since I last installed a network though. Safest to (mentally at least) prepare for that swine Finagle and his mad prophet Murphy...

I've seen both used very frequently around here (South Africa). STP is used mainly where the engineer/admin in charge of the network is worried about interference (or in one memorable case, where the admin was incredibly - and hilariously - paranoid), while UTP is mostly used where the engineer/admin wants the job done NOW so we can go party for the weekend.

Bearing in mind that in this country we have at least two sets of international standards that we try to conform to, often 3 or more.

I think you have to special order STP in Ameica.. I haven't been able to find it out in any stores or anything. I suppose it has something to do with your power grids being more advanced than in the US.

Running over lights is never good.. there is a reason they're shrouded in metal, even though its already grounded. It blocks of a lot of interference. I had that problem in college.. they ran 5000' of cabling over the lights. I had to crawl through the ceiling and rerun at least 2000' because they ran over the lights and were too short to reach after the rerouting.

I like telling people the longer the cable, the longer it takes for the data to get there. People are dumb.

I'm not really network savvy, but after reading this thread I can tell that the retard that installed ours wasn't either.

Indeed that's correct. The guy who "installed", and I use that term loosely, the cabling really just installs phone systems and doesn't know jack. Unfortunately he was in cahoots with the guy who spec'd the computer system as well. They did a first class job too because a single proc PIII 512MB Dell server does great job at running a SQL database, web server (not anymore), & mail server at the same time. And those 10 Dell 128MB, P4 S478 Willys they spec'd run XP great once they cache for an hour before login. And let's not forget the great website the "computer guy's son" put together. Truly a work of art in modern online security because our customers all had to login under the same password. It was so simple and such a great idea. I cannot understand why nobody else thought of it.

STP around here is only slightly less readily available than UTP, but at least twice the price - I'm not really sure how our power grids stack up in comparison to the US, but lately I'm not really impressed.

After last year, though, the Western Cape (where I live) was the only province that was prepared for power issues when they spread to the rest of the country in January - UPSes, generators, you name it, we have it (and the rest of the country had UPS/generator/etc shortages ).

Telling people that little 'myth' about the length of cable and time data takes to travel is often the easiest way to get the damn job done to decent standards in spite of client interference. The kicker is that it's actually true (immeasurably so, but yeah).

Little story I regularly use on clients - a ship pulls into the dock with severe engine trouble, and the ship engineers haven't a clue what's going on. So they call in an engineer from the town, who duly goes through to the engine room. Once he's in there, all he does is listen to this, feel that, inspect something else... and after about four or five hours extracts a tiny little hammer from inside his case and whacks something with it. Engine trouble mysteriously just goes away. So he hands the captain a bill for R10,000. The captain submits the bill to the company, who send it back asking for an itemised invoice.

The itemised invoice read as follows:
Hitting widget with hammer: R5.00
Knowing which widget to hit: R9995.00

About the only difference there on the 3 occasions I put in phone nets (at the same time as ethernetworks, go figure) I used specific cabling - cat2 (or is it 3?) for phones, cat5e for ethernet. Otherwise, the two networks were indistinguishable - and the bloody monkeys (sorry AV) maintaining the things still get the two mixed up every time they have to make a modification to the cabling. *sigh*

Cat3 is becoming hard to find because it costs just as much as Cat5e these days.

If you ever run phone lines, might as well run Cat5e to make them digital ready and should you need a line, you already have it run instead of a Cat3 slow cable.

I don't bother anymore because its time consuming and the money isn't there. Everyone thinks they can run the cable and punch down themselves. Go for it.. people screw up like no other.

In fact, we had Blackbox come in and rewire one of our plants. Probably 48 nodes. After they tested them with their cabling equipment and gave the OK and left, we found out less than 50% of them functioned.

Called them back in and they blamed dust for making the connections not work.

I got screwed on a couple jobs. I was only charging $50/hr @ 30 hrs or less of work.

I had to setup a 2k small business server, email, rebuild 20 desktops, add them to the network, run all the cable, install all the software, make sure that worked, document and have someone trained on it.

It was for someone I used to go to college with and I was helping out.. so $1500 for all wasn't a big deal. He was getting quotes of $10k to do it.

When it came down to it, I went in without a contract and the guy only gave me $700.

The best part was the next day the guy screwed the server up and made a backup over the tape that I had a working back up on. He lost it all and had to pay $5k to get someone in to fix it.

Yeah, you'll do good. That's fair price for cabling.

I can order cabling from CDW fairly cheap with cheap shipping. I went into a CompUSA and spent $200 on what CDW would cost me $30.
