480 xt connecting to hpe brocade 8/24

Hi

I have a Unity XT 480 and want to connect it to an HPE 8/24  switch (Max speed is 8Gbps) In Unisphere I can see 8GB selection option for FC ports but the port doesn't power up in SAN switch. Saw somewhere that I/O ports on 480 XT only works with 16/32 so this connection will not be established after all.

Any idea?

Thanks
