I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Single IP Address Management — single IP address management for a virtual stack of up to 16 switches

So I guess it's 16 switches max.

But can these be connected via the backplane or must one use a port?
Zephyr ICTCloud ArchitectCommented:
No, it's not that kind of stacking I'm afraid, this document (page 6-3) explains how this stacking is working. You need to use normal network cabling.

You mean the modules on the back? Those aren't for stacking, there's no special stacking cables available for this switch, like I said, just stacking via normal network cabling.

The available modules for this switch are these

Can one use below ports to interconnect them to look like one switch?
 2-port 10 Gigabit switch expansion module. This module has two fixed CX4 ports.(1)

Theoretically that is possible yes, maybe will be expensive though :-)
