Aruba Modular Switches

Hi everyone,

we consider to expand out network and get rid of our old 48 port switches. I’ve figured out the Aruba 5400 series is a good choice but I’ve a few questions which may can be answered by someone here.

If I understand everything right you buy a shelf and equip it with the different modules. So you can buy modules with 24 GBit ethernet ports for your clients and modules with SFP+ ports for 10Gbit uplink for your Servers right?

I’ve seen you can also buy the PSU for the shelf. The PSUs are available in different sizes, how do I know which one I need? I think if i’m using PoE moduls i need a bigger one?

My next question is about the shelf: Which size has the best price/size ratio? Is it possible to expand the shelf?

Did I need the management modul for the switch? I need the possibility of creating VLANs and trunkings and maybe inter vlan routing.

Is it possible to manage the swicht via telnet like the Procurve switches?

Thanks in advance for answering my questions and sorry for the bad english but i’m no native speaker.
