Mr. P Posted October 10, 2018 Posted October 10, 2018 I have a TP-Link 16 port gigabit switch and I am adding another TP-Link 8 port gigabit switch to extend my network. The cat5 from the 16 port to the 8 port, is it a patch or crossover? In the old days you needed a crossover for like devices but aren't most devices auto sensing/configuring today. https://smile.amazon.com/gp/product/B00A121WN6/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1
LOR Staff Posted October 10, 2018 Posted October 10, 2018 You are right on all accounts. You used to need a crossover cable, but I don't think there is a switch mfg today that doesn't have auto-sense. When cascading switches now a days, I don't even think about it - I just run a normal straight CAT5/6 from one to the other.
Mr. P Posted October 10, 2018 Author Posted October 10, 2018 Thanks DevMike, I just wanted to confirm before I started hooking everything up.
TheDucks Posted October 10, 2018 Posted October 10, 2018 Another 'old school' rule (10b5) that seems to have gone away. 2.5M between nodes (But they still seem to make/ship standard patch cables 7' ?)

They do that for some of the old equipment still in use out there. On occasion you might need an actual crossover cat cable, so they still make them presently for that reason. One day they may go away entirely, but I don't think that's about to happen for a little while longer yet.
Little_b Posted October 11, 2018 Posted October 11, 2018 Mr. P- I've added 3 Netgear switches to my display to help contain the cables from the controllers. Each switch is linked to one to the next using regular Cat5e cable and I haven't had any issues.
LOR Staff Posted October 11, 2018 Posted October 11, 2018 I believe the minimum was only for ring topologies, not star. Something about impedance if I remember correctly. Who uses ring?
TheDucks Posted October 12, 2018 Posted October 12, 2018 I installed 5 segments of thick (10b5) Ethernet with over 200 vampire taps. (centered on the stripe) and connected to workstations or a 'fan out box' I only saw(and cleaned up) remnants of Token Ring CAT5 is so much easier!
jfuller8400 Posted October 12, 2018 Posted October 12, 2018 Hey, token-ring was great. Deterministic transmission times and built in resiliency. Who could ask for more? Too bad it was so much more expensive. Cat5 is easier, though. 2

When businesses had a choice of $800 for a token ring card and $150 for ethernet, well you know what decision most made. And lets not forget ArcNet (star topology). 1

a31ford Posted October 14, 2018 Posted October 14, 2018 Still have a MAU reset tool around here somewhere ….
