QFX5200 AC Power Supply Description

The two power supplies in QFX5200 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. QFX5200 switches can operate with one PSU, but two power supplies are required to run
without error messages and to have redundancy. See
for examples of QFX5200 AC power supplies.
The AC power supply in QFX5200-32C and QFX5200-32C-L switches is 850 W; the AC power supply
in QFX5200-48Y switches is 650 W. Be sure to use the correct power supply for your chassis product
SKU (see Table 17 on page
Figure 23 on page 40
