Descripon
The power supplies in QFX5200 switches (see Figure 28 on page 48 and Figure 29 on page 49) are
hot-removable and hot-insertable eld-replaceable units (FRUs). You can install the power supplies
without powering o the switch or disrupng the switching funcon. QFX5200 switches can operate
with one PSU, but two power supplies are required to run without error messages and to have
redundancy.
The DC power supply in QFX5200-32C is 1100 W with dual feeds for power resiliency.
