The switch uses removable power modules and fan trays. It supports the LSVM1AC650 and
LSVM1DC650 power modules and the LSWM1BFANSC and LSWM1BFANSCB fan trays.
Power modules
WARNING!
When the switch has power modules in redundancy, you can replace a power module without
powering off the switch. To avoid device damage and personal injury, make sure the power module
is powered off before you replace it.
The switch can operate correctly with two power modules. You can install three or four power
modules on the switch for 2+1 or 2+2 redundancy, respectively.
