QFX5110 AC Power Supply
Except for the QFX5110-32Q-CHAS, the QFX5110 switches are shipped from the factory
with two 650 W power supplies pre-installed. See Figure 15 on page 34 for an example
of a QFX5110 AC power supply. Each power supply is a hot-removable and hot-insertable
field-replaceable unit (FRU) when the second power supply is installed and running. You
can install replacement power supplies in the two slots next to the fan modules without
powering off the switch or disrupting the switching function.
The AC power supply in QFX5110 switches is available in different airflow configurations.
Be sure to use the correct power supply for your chassis product SKU (see
Table 14 on page 35).
CAUTION: Do not mix power supplies with different airflow. The system
raises an alarm when a power supply having a different airflow or wattage
is inserted into the chassis.
