Comware

Hello 

I recently acquired two HP 5500 El switches for my lab environment and would like to stack them.

I have learned that there are no dedicated stack ports for these switches and that I need a stack module and CX4 cables to stack them.

How many CX4 cables do I need to stack these switches, and how should I connect the wires?

Please also share documents describing the topology for two switches, if available.

Thank you.

Hi Perton

You only need 1 stack cable.for a 2-members stack

More cables -> more backplane capacity (and a little more resiliency !)

Follow the procedure "Setting up an IRF fabric" in "HP A5500 EI & A5500 SI Switch Series Installation Guide "

Personnaly, I always connect "ports1" of one stack member  to "ports 2" of the next member in the stack. (like a ring topology ) That leads to a repeatable, symmetric configuration.
