Cannot Get Dynamic Ip

[lionsl2005]

Hi Guys,

 

During the Half term couple of the network cables been cut by the onsite building constructors. but they but a joint box anf sixed the problem. after this two class toom pcs not getting the Dynamic IP from the DHCP. when i dis check the ipconfig / all it shows Nod type as Paired. but rest of the computers in school shows as Hybrid, What are these. what is Paired or hybrid. is this caused the problem?

what do you mean by joint box ? A switch ?

[lionsl2005]

This is the connection box they installed.

Can you show us the cabling inside the boxes?

[lionsl2005]

i will try.

Here you go.

Wow I've never seen those...so basically a splice for Cat5e....

 

Probably pretty close to the worst idea I've even seen. Get rid of them.

This is been set up by the contractors company. This incident happened while they working on school expansion project.

As neat as they are, you don't do that with network cable. Even worse if it's for longer cable runs. I would insist they came back out and replaced the entire run.

The junction boxes are fine to use but over longer distances they may not be quite up to the job.

 

When our building expansion goes ahead we have asked for complete new runs.

[synaesthesia]

Oh, forgot to ask - have you actually checked the cabling? (or got someone with the equipment to do it for you)

I have to admit, never seen anything like that myself either. To me the problem's seriously over engineered. You're just as well to expose the copper and wrap it with security tape in the short term. At least then it would fit back into the existing trunking and workstations can connect properly with DHCP.

There's nothing wrong with those boxes - they are designed just for that purpose, but you really need a network cable tester to make sure they are ok from end to end and connected correctly. There is the possibility of more than one break or the cable run might simply be too long.

I'm thinking the same. I'm getting someone to check it tomorrow.

I'd have to disagree. This is UTP copper, and the more you expose and untwist the pairs, the more crosstalk you introduce. Cat5e was not meant to be spliced. In addition they've installed them incorrectly by feeding both ends through the same side of the box - they're designed to have one end come in each side.
