The two power supplies in QFX5100 switches are hot-removable and hot-insertable
field-replaceable units (FRUs). The power supplies are installed in the switch at the
factory. You can install replacement power supplies from the management panel without
powering off the switch or disrupting the switching function.
The AC power supply in 1 U QFX5100 switches is 650 W; the AC power supply in the 2 U,
QFX5100-96S switch, is 850 W. Both power supplies look identical. Be sure to use the
