QFX5200 Power System

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 Figure 1 and Figure 2 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 1).

CAUTION:

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.

You may mix AC and DC power supplies with the same airflow in QFX5200-48Y, but load sharing is different between the two designs.

The power supply provides FRU-to-port or port-to-FRU airflow depending on the product SKU you purchase. The power supplies have color-coded indicators to indicate the airflow direction. Either the PSU handle or the panel behind the handle are color-coded. See Figure 3 for an example of the QFX5200-32C and QFX5200-32C-L power supplies and Table 1 to determine the airflow of the PSU.

CAUTION:

Verify that the airflow direction on the power supply handle matches the direction of airflow in the chassis. Ensure that each power supply you install in the chassis has the same airflow direction. If you install power supplies with two different airflow directions, Junos OS raises an alarm. If you need to convert the airflow pattern on a chassis, you must change out all the fans and power supplies at one time to use the new direction.

To supply sufficient power, terminate the DC input wiring on a facility DC source that is capable of supplying a minimum of 7 A at –48 VDC.

To avoid electrical injury, carefully follow instructions in Connecting AC Power to a QFX5200.

QFX5200 Power Cord Specifications

Detachable AC power cords are shipped with the chassis, if you include them as part of your order. The coupler is type C13 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.

Note:

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.

QFX5200 AC Power Supply LEDs

The QFX5200-32C and QFX5200-32C-L uses three LEDs to indicate power status, while the QFX5200-48Y has a single bi-colored LED for power status.Figure 4 shows the location of the LEDs on the QFX5200-32C power supply. Figure 5 shows the LED location on a QFX5200-48Y power supply.

QFX5200 DC Power Supply Description

The power supplies in QFX5200 switches (see Figure 6 and Figure 7) are hot-removable and hot-insertable field-replaceable units (FRUs). You can install the power supplies 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.

The DC power supply in QFX5200-32C is 1100 W with dual feeds for power resiliency.
