Question about adding a switch

Switch5 (NEW)

In the above illustration:

All switches are connected by fiber.

All switches and hubs are populated with computers

Switch 1 is the main switch

Does adding Switch 5 to Switch3 violate the 5-4-3 rule?

(This would be the most cost effective spot for it)

If so where should it be added?

Thanks for your help.

Well I don't know how your design started out this way but what you really need to do is have one of your switches at the top and all other hubs and switches directly connect to that switch via a star formation. Then I would replace your hubs with switches.

I may have illustrated it incorrectly,

it started as a star but 3 was added to 2

because Switch 1 only had 2 fiber ports

Now I either need to add another switch

on top of 1 with fiber, of which nome of

the copper ports are used and add SW5 on

the other end, Or Add 5 directly to 3.

Will adding 5 to 3 work or do I need to

look at an alternative?

Hub1--->| |<---Switch4

Hub2--->|Switch1|<---Switch2<--Switch3(<--SW5?)

If you need more fiber connections just buy a couple of copper to fiber media converters, cheaper than buying a whole new switch though it does add another potential point of failure .

The 5-4-3 rule does not apply to switched ethernet networks. It applies only to shared-access networks. Please check these links:
