QFX5210 Power System
QFX5210 AC Power Supply
The two power supplies in QFX5210 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. See Figure 1 and Figure 2 for examples of the QFX5210 AC power supply.

Each of the 1100-W power supplies has a single AC input. and a 12-VDC output, with a standby voltage of 12 VDC. Each power supply provides sufficient power for all of the components in the device. This redundant configuration is known as 2N redundancy. A 2N redundant power system transfers the electrical load without interruption if a power supply fails or is removed.
Each power supply module has an internal fan that assists device cooling. The airflow for the power supplies must match the airflow of the fans. Power supplies and fans are color-coded for each airflow.Table 1 shows the different power supplies and their airflow direction.

To avoid electrical injury, carefully follow instructions in Connecting AC Power to a QFX5210 or Connecting DC Power to a QFX5210.
Do not mix power supplies with different airflow or different wattage. The system raises an alarm when a power supply having a different airflow or wattage is inserted into the chassis.

AC Power Cord with Type C15 Coupler Specifications
Detachable AC power cords are shipped with the chassis, if you include them as part of your order. Some country-specific plugs are only available as spare orders. The coupler is type C15 as described by International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.
In North America, AC power cords must not exceed 14.75 feet (approximately 4.5 meters) in length to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC) Section 4-010(3). The cords that can be ordered for the QFX Series switches are in compliance with these guidelines.
Table 3 lists the AC power cord specifications provided for each country or region.
