Daisy Chain a Switch (hub)

[mh348]

Is there a Maximum distance when daisy-chaining (linking two switches with a cross-over cable)?

I have a Client with PC's in two buildings, 7 PC's in Building A and 1 pc in Building B, they have a single UTP cable running underground from Building A to B.

Now they would like to add another PC to Building B, so instead of laying a new cable I taught I could simply add a Switch to Building B and make the cable a crossover. the distance of the cable is around 35 to 40 meters.

Would this work or would it cause problems?

should be fine max is between 90-100m

most new switches auto detect whether you are using a straight-though or cross-over cable.

Yes, I was just checking up on that, if it says MDI/MDI-x then it can auto detect.

Maybe look into so lighting protection, outdoor Ethernet not always the best of ideas.

I'm sure the original post says underground

I would invest in a fiber link between the two buildings - lightning is a funny thing, and the possibility exists that it might zap the underground cable.

Or two wireless transmitters.

Ja, I did notice.

The switch would be suitable, if possible first try a smallish switch just to check if if works and that the link speed is ok (if that is an issue)

If possible, avoid the cheapy-switches and go for a branded switch as the branded stuff usually performs much better than the cheap junk.

Had a cheap 8-port 100Mb switch whose PSU went titsup with the first wave of loadshedding

We've had an ethernet cable spanning two buildings at roof level for more than five years. Only had one lightning strike in all that time - took out the two switches and some NICs. They say lightning never strikes twice in the same place so we should be ok now! Don't worry about the crossover cable, not necessary, the new switch should be able to handle it fine.... we have about five switches in a chain and it runs fine.

If you run it underground, best put it in some PVC pipe, the cable isn't suited for that environment unless otherwise specified (plain cable in the ground is such a backyard job but anyway ). As for the lightning, I have a cable that runs from one point in our home to another point underground (in PVC), and haven't had any problems, been 3 years now (their buried pretty deep tho, my sister is avid gardener so must avoid the pitch fork ).
