3Com 4400 Stack

[Hboogie]

Hey All:

I have three 4400's. I want to purchase another 4400 and want to stack it with the existing three. Each 4400 has two module ports. Below is my current setup

Switch One: Stacking Card
Switch Two: Cascade Unit
Switch Three: Stacking card

I imagine when i purchase switch four, i would need to purchase another cascade unit and stacking card ?

Below is what i'm assuming would work...

Switch one: Stacking Card
Switch Two: Cascade Unit
Switch Three: Cascade unit ?
Switch Four : Stacking Card ?

This, i presume, would still allow me to keep the second module's free. To perform the following....

Switch One: Gbic module Connecting to Switch Two's Gbic module

Switch Three: Gbic module Connecting to Switch Four's Gbic module

Then from switch four connect to my 4924 using Cat 6 ? To complete the GIG chain

Thanks,

HS

You will need a stacking kit, and a stack extender kit to add another 4400 to your existing stack.

I dont understand what you are doing with the gig fiber, the units are already stacked.

The rule of thumb for stacking 4400s is (number of switches in stack) minus 2 = (number of stacking extender kits you need). Stacking kits include two modules, each with one port, and cables. Stack extender kits include one module with two ports, and cables. One module from the stacking kit goes in the bottom switch and the other module goes in the top switch in the stack. It can be hard to understand unless you visualize it....
