hi to all,

because of 100 meters cat5e cable limit, it is a solution to use a repeater or a switch to extend the limit. but how does it affect the network if it is done again let's say 3 times, and is it still could be able to connect workstations on every switch?

e.g. :

90m
|
16 port switch
|
90m
|
24 port switch
| | |
PC PC PC

what is the 543 rule?
is the 543 rule applies to this?

any suggestion or link related to this subject:

tnx in advanced

You only need to worry about the 5-4-3 rule if you use hubs and/or repeaters.

Since you are using switches, you won't have a problem.

Just to close this one off for the benefit of those reading, the 5-4-3 rule as stated defines how much you can extend and Ethernet network using repeaters or hubs. You can have a total of five segments, connected together in a line by four repeaters/hubs, and three of the segments can have active devices (PCs, servers etc) on them. The other two segments have to be point-to-point links used solely to extend the distance. The rule exists to make sure that the collision domain doesn't become too large for the CSMA/CD mechanism to operate effectively
