Cable Termination - What Happens If

26 May 2009 10:24 AM

Hi all

Had a break in at the office over the weekend - damage included a network
point being pulled off the end of the Cat5 cable.
If the reconnection of this point is done incorrectly, can this screw up the
rest of the network, or will the switch to which it is connected simply
ignore it?
The infrastructure includes a gigabit server switch with local 100Mbit
switches "below" this. The damaged network point is patched into one of
these 100Mbit switches.

TIA

If the wires in the ice cube (the connector) were pulled out, the switch simply will ignore it. It won't affect the rest of the network, just that computer. If the wire is connecting the switch to the router/firewall, or as in your case to another switch, then yes, it will affect part or the rest of the network, depending on what the other switch is plugged in to. Also, the perpetrator could have damaged the port.

The best thing to try is to plug it into a different port. If that doesn't work, replace the cable and plug it into the original port.

Sorry the original post was obviously not clear!
The damage resulted in the wall socket being pulled clean out of the
skirting/trunking leaving just Cat5 cable hanging out of the wall (the Cat5
going back to the patch panel and switch).
The joint needing to be remade is the reconnection of the "female" wall
module.

Hmm, I'm not sure what you mean by the wall socket, wall module or female wall module. Maybe if you can supply a link to a pic, I can better understand what you're saying.

Do you mean all of the cat5 cable coming from all of your workstations to the patch panel got yanked and they are all just hanging there now? Or was this a connector connecting two stacked switches?

Ace, I think he means an RJ45 connector in a wall jack so your answer still
holds I believe.

Something like;

It's kind of what I thought, but his last post said "[...] just Cat5 cable hanging out of the wall [...]" which I thought and he assumed being plural? I'm not sure at this point.
