Damaged cat5e cable and some...

Removable Media Drives - Tech Support Forum - www.techsupportforum.com
Hi all, sorry for long post. we currently have an issue with a cable (about 75 metres). It connects one netgear unmanaged switch to another one in a different building. At the remote location, there are 3 devices connected to switch. A couple of days ago it stopped responding (well almost - I'd get maybe 1 ping reply out of 30). I asked someone at the site (I dont work there) to take the long link cable out of the netgear and plug straight into one of the devices - I got 100% ping replies from this device!

So I thought the remote netgear is faulty. I went to that site the next day with a new netgear. New netgear didn't work either. I cut off the rj45 ends and did a continuity test on all 8 wires inside the long cable - all responded except the solid blue wire. I traced the cable and found that something had chewed the cable (rodent problem on site) and the blue wire was visibly cut. So I put a join in and now all 8 wires are passing the continuity test. I put new ends on and test with rj45 tester and it says all pairs are correct but the 'short' warning light is on.

We cannot run a new cable to this place so I'm going to put a wireless signal over there. However this is what is happening when each device is plugged directly plugged into the long cable and I'm desperate to know why..

Device 1 responds 100% pings (the device is this -

)

Device 2 and 3 responds maybe 3% pings

(The devices are swann CCTV servers)

Hope someone can help! Thanks, John
