hello, does any one knows if the Summit x450-24x (not x450a, so the first x450) will work with 2xSFP+ 10G module (or any newer than for XENPAK) ??? data sheet lists only the one for XENPAK, but.. it is quite not up to date. Btw, how do I enable stacking in this switch ? there is no enable stacking command. XOS 11.4 Regards, Marcin
