You are very welcome Antonis.
Since I mentioned talking about tools in this discussion forum...
Here is an image of the RJ-45 Network Tester I used for testing each node/trunk... plus test the patch cables used to connect up the new router and patch panel.
It is the DataShark #70025 from Paladin Tools. The kit is supplied with the tester/signal generator, two 6" inch patch cables, and the remote signal test receiver/display.
The kit also includes a black pouch/carrying case and retails for around $25.00 (US).
Of all the testors I looked at... this one was priced within my reach and worked very well. A true time saver.
