QFX5130-32CD Power System

The power supplies in QFX5130-32CD models are hot-removable and hot-insertable field-replaceable units (FRUs). You can install replacement power supplies without powering off the device or disrupting switching function. The power supplies are installed at the factory and shipped with the chassis. All power supplies for QFX5130-32CD are 1600 W.

CAUTION:

Only use the power supply for your model number and airflow. 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.

The power supplies for the QFX5130-32CD are located on the FRU panel. See Figure 1.

QFX5130-32CD AC Power Supply Modules Description

The QFX5130-32CD ships with two power supplies. While QFX5130-32CD can operate with the minimum number of power supplies, maximum power supplies are required to have redundancy. See Figure 2 for examples of these power supply modules.

Figure 2: 1600-W AC Power Supply for QFX5130-32CD1600-W AC Power Supply for QFX5130-32CD

An AC power supply for the QFX5130-32CD is 1600 W.

The power supply provides FRU-to-port or port-to-FRU airflow depending on the model and variant you purchase. The power supplies have color-coded indicators to indicate the airflow direction.

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 avoid electrical injury, carefully follow instructions in Connecting the QFX5130-32CD to Power.

The QFX5130-32CD AC model uses power cords with type C15 couplers, see AC Power Cord with Type C15 Coupler Specifications.

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.

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.

Blinking

The power supply is an invalid model.

Note:

If the input and output LEDs are unlit, either the AC power cord is not installed properly or the power supply fuse has failed. If the input LED is lit and the output LED is unlit, the AC power supply is installed properly, but the power supply has an internal failure.

QFX5130-32CD DC Power Supply Description

The DC power supplies in the QFX5130-32CD (see Figure 4) are hot-removable and hot-insertable field-replaceable units (FRUs) that install without powering off the device or disrupting the switching function. The factory installed power supplies in both models are 1600-W, but are not interchangeable. The QFX5130-32CD is shipped with two power supplies. Each power supply provides 2400 W of power to the chassis.

Both power supplies have double the amount of power supplies needed to power all of the components in the switch, which is known as 2n redundancy. When the switch has all of the power supplies installed, the switch has full power redundancy. If a power supply fails or is removed, a second power supply balances the electrical load without interruption. For more on redundancy features, see QFX5130-32CD Component Redundancy. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.

Figure 4: DC Power Supply in QFX5130-32CDDC Power Supply in QFX5130-32CD
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 Evolved 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.

Table 5 shows the characteristics of the power supply and the direction of the airflow.
