introduction

I've got a stack of PCs. I need network switches, NICs and cables to turn them into a data network. My data network follows the ethernet standard.

I added up how many ethernet interfaces and data cables I would need.

ethernet things

I bought ethernet switches to handle the paths of the LIC network. I bought many more ports than I needed so I can expand the LIC later. I ended up with two big old 48 port switches and one 24 port switch. The 48 port switches have lots of cooling fans inside them so they are annoyingly noisy to run. Perhaps they were put up for office clearance by neauvou-deaf employees.

Each IBM PC (International Business Machines Personal Computer) contains a few NICs (Network Interface Cards). I bought the cheapest ones I could find that use the Realtek RTL8139 chips. They are very common and I know they work with my OS.

Lots of coloured data cables run from the switches to the PCs. A few cables are cross-over and the rest are straight-through. These cross-over (AKA X-over) cables connect one PC to another PC, not to a switch.

The cables are long enough for most jobs. They are too long for me to bundle them neatly. Untidy cables are a maintenance nightmare, so I adjust their length using cable assembly tools. I use these to create a network cable of exactly the right length.

I found a supplier of old hardware. I bought a vanload of stuff.

I bought more cables than I need. A box of 20 cables is not much more expensive than buying a few singles.
