    Hi Fredrik, and thankyou for your response; I have a couple more questions
    for you :)

    As I understand this then, the two switches do not share the same 'fabric'
    of connections to the blades. i.e. I can have my blades in one IP network
    that is redundant across both switches (using both blade interfaces), or
    have two IP networks (one on each switch) with no redundancy; What I need
    to know is whether or not I can have a switch set up with VLANs of two IP
    networks, and the other switch monitoring it and doing some sort of
    availability checking (e.g. heartbeat, or something) and 'takes over' the
    connections if the first one fails. As you say each blade is connected to
    each switch on each of it's interfaces, I suspect this isn't possible...

    Which does lead me onto another question -- the B200X blades have 4 ports
    IIRC; what do they plug into?

    Again, I'm new to the whole tech so please excuse my ignorance.

    Many thanks,

    Steph
