The Summit X650 series switch must have an installed VIM; the switch will not operate correctly and
enter into reboot loop without a VIM.
Note
The Summit X650 switches require VIM1 or VIM3 modules. Other VIM types that may appear
to be mechanically compatible with the Summit X650 switches will not function if they are
installed in these switches.
Cooling is provided by a replaceable fan module. Two power supply bays accommodate either AC or DC
power supplies.
