QFX5220 Power System

The power supplies in QFX5220 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 QFX5220 are 1600 W; however, the power supplies for the QFX5220-32CD and the QFX5220-128C are not interchangeable.

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 QFX5220 are located on the FRU panel. See Figure 1 and Figure 2.

Note:

A QFX5220 chassis must have a minimum of one PSM available for a row. Acceptable PEM configurations with two PEMs are (0,2), (0,3), (1,2), and (1,3), while configurations with two PEMs that are not supported are (0,1), (2,3).

QFX5220 AC Power Supply Modules Description

The QFX5220-32CD ships with two power supplies; the QFX5220-128C ships with four power supplies. While each model can operate with the minimum number of power supplies (one for QFX5220-32CD, two for QFX5220-128C), maximum power supplies are required to have redundancy. See Figure 3 and Figure 4 for examples of these power supply modules.

An AC power supply for the QFX5220 is 1600 W. However, the power supplies for the QFX5220-32CD and the QFX5220-128C are not interchangeable. Be sure to use the correct power supply for your chassis product variant (see Table 1).

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.

Table 1: DC Power Supply Summary
Model	Product Number	Airflow Direction	Color Indicator
QFX5220-32CD	JPSU-1600W-1UACAFI	Airflow In (FRU-to port)	Juniper azure blue handle
QFX5220-32CD	JPSU-1600W-1UACAFO	Airflow Out (port-to-FRU)	Juniper gold handle
QFX5220-128C	JPSU-1600W-AC-AFO	Airflow Out (port-to-FRU)	Juniper gold handle

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 QFX5220 to Power.

Table 5 describes the LED behavior on the QFX5220-32CD AC power supplies.

Table 5: AC Power Supply LEDs on a QFX5220-32CD
LED	Color	State	Description
AC input okay	Unlit	Off	The power supply is disconnected from power, or power is not coming into the power supply.
AC input okay	Green	On steadily	Power is coming into the power supply.
DC output okay	Unlit	Off	The power supply is disconnected from power, or the power supply is not sending out power correctly.
DC output okay	Green	On steadily	The power supply is sending out power correctly.
Fault	Amber	On steadily	An error has been detected in the power supply. Replace the power supply as soon as possible. To maintain proper airflow through the chassis, leave the power supply installed in the chassis until you are ready to replace it.
Fault	Amber	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.

QFX5220 DC Power Supply Description

The DC power supplies in the QFX5220 (see Figure 7 and Figure 8) 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 QFX5220-128C switch has four power supplies and the QFX5220-32CD is shipped with two power supplies. Each power supply provides 1600 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 QFX5220 Component Redundancy. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.

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 6 shows the characteristics of the power supply and the direction of the airflow.

Table 6: DC Power Supply Summary
Model	Wattage	Product Number	Direction of Airflow	Color of Power Supply Handle
QFX5220-128C	1600-W	JPSU-1600W-DC-AFO	Airflow Out (port-to-FRU)	Juniper gold

QFX5220-32CD	1600-W	JPSU-1600W-1UDCAFO	Airflow Out (port-to-FRU)	Juniper gold handle

We recommend that the 48 VDC facility DC source be equipped with a circuit breaker rated at 40 A (–48 VDC) minimum, or as required by local code.

To avoid electrical injury, carefully follow instructions in Maintaining the QFX5220 Power System .

QFX5220-128C DC Power Cable Specification

QFX5220-128C DC power supplies require a D-Sub 3W3- type connector. The three pins on the connector provide –48 VDC input (–), return (+), and ground connections to the power supply.

Note:

The optional right-angle DC power cables, CBL-JNP-PWR-DSUB2 and CBL-JNP-PWR-DSUB3, do not include a ground connection wire. Regardless which DC power cable you use, you must connect the QFX5220 to earth ground before you connect it to power, using the procedure described in Ground the QFX5220-128C.

DC power cables, each 4 m (approximately 13.1 ft) long, are supplied with the QFX5220-128C. The provided cables include the three-pin connector on one end and three insulated wires at the opposite end, for connection to the site’s DC power distribution system.

Table 8 lists the specifications for the QFX5220-128C DC power cables.

Table 8: QFX5220-128C DC Power Cable Specifications
Juniper Model Number	Wire Function	Insulation Color	Wire Size
CBL-JNP-PWR-DSUB (straight cable)	–48 VDC input (–)	Blue	8 AWG (8.4 mm²), 90° C
	Return (+)	Black	8 AWG (8.4 mm²), 90° C
	Ground	Green and yellow	8 AWG (8.4 mm²), 90° C

	Return (+)	Gray	8 AWG (8.4 mm²), 90° C

Warning:

For field-wiring connections, use copper conductors only.

Warning:

Power cables must not block access to QFX5220 components or drape where people could trip on them.

CAUTION:

You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site might be different from the color coding for the leads on the DC power cable provided with the chassis.
