currently, we have 2 building with 2 wiring closet.

 

Building A has 10 ports

 

Building B has 35 ports

 

 

There are fiber connection between 2 buildings and there is no copper wiring connection in between.

 

Unfortunaltely, all the server equipment  is at building A. 

 

My idea is to purchase 3 Powerconnect 2724 s, and use one as the core switch in building A.  Can Powerconnect 2724 use its 2 fiber port uplink to the other 2 powerconnect 2724?

 

Or is there other better and cost effective way to do what I am doing?
