The person before me setup 2 HP Procurve 2724 switches. Because of network growth, I need to add a third switch. Now I always thought to add an addtional switch you would use a crossover cable and connect it between the 2 switches.
That was not done here. I can not see how the second switch is working.
So, my question is can I use a cross over cable to connect the 2 switches or do I need to go through the wall panel.
