best way to connect multiple network switches

I have 6 switches that need to be connected together. Internet is coming into one switch and all of the other switches need to be connected to it.
should the be connected s1 to s2 to s3 to s4 to s5 to s6
or
s1 to s2, s3,s4,s5,s6?

The "cascade" (s1 -> s2 -> s3....) should be avoided.
In this case failure of a device in the middle will disable all devices down the line.

For six switches I'd recommend the "star":

s1 -> s2
s1 -> s3
s2 -> s3
s2 -> s4
s3 -> s4
s3 -> s5
s4 -> s5
s4 -> s6
s5 -> s6

nope.. the benefits are what Philip said, plus its only one hop to the central switch instead of multiple hops.

What kind of switches do you have? Are those L3 devices? Did you configure ports properly, so you don't get a circle?

We need to know what kind of switches you have.  They will definitely need to be configured properly.

oh..one of those deals huh?
are they all managed switches? or do we have a mix of some commercial grade and consumer grade stuff here?
That is a mess by the way.

they should all be managed

Do you have a single vlan network or multiple vlans?  Really the port configurations shouldn't be any different than what you had.

So on the top level switch, which only had a single switch connected to it... look at that port and mimic for the other 5 switches.

Then use the same uplink port you used on the other switches.

one lan and one vlan, all ports for vlan are tagged and non vlan untagged.

according to the previous comment switch 1 is suppose to be connected to 2 and 3.

oh oh oh.. i see.. i didn't read what phillip said completely.. i misunderstood when he said star.  I was thinking hub-spoke topology when i was addressing this.

So the star gives you more redundancy but you have to deal with spanning-tree and how each switch handles spanning-tree.  You have 4 different models of switches and from the sounds of it  - not being critical on you - not a lot of expertise in each one of these or you would not have needed to ask the question.  

So given your case I would keep things simple and do a hub-spoke with each switch being connected to S1.    That is what i was referring to.  sorry been sick all week and on meds and didn't read that clearly in the beginning.
