QFX10002 Power System

QFX10002 AC Power Supply Description

The AC power supplies in QFX10002 models (see Figure 1) are hot-removable, and hot-insertable field-replaceable units (FRUs) that you can install without powering off the switch or disrupting the switching function. The QFX10002-36Q switch has two power supplies; the QFX10002-60C and QFX10002-72Q have four power supplies. All of the power supplies are installed at the factory.

Each of the 1600-W power supplies has a single AC input. A QFX10002 has 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 configuration options, see QFX10002 Component Redundancy. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.

The fan in the power supply provides port-to-FRU airflow, which is also known as airflow out (AFO). A power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

AC Power Cord Specifications for QFX10002 Switches

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.

QFX10002 DC Power Supply Description

The DC power supplies in QFX10002 models (see Figure 2) are hot-removable and hot-insertable field-replaceable units (FRUs) that install without powering off the device or disrupting the switching function. The two 1600-W power supplies in a QFX10002-36Q are installed at the factory and supply 1200 W of power to the chassis. Likewise, the four 1600-W power supplies in a QFX10002-72Q switch are installed at the factory and supply 2400 W of power to the chassis.

A QFX10002 has 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 QFX10002 Component Redundancy. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.

QFX10002 DC Power Cable Specifications

QFX10002 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. See Connecting the QFX10002 to Ground.

DC power cables, each 4 m (approximately 13.1 ft) long, are supplied with the QFX10002. 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 7 lists the specifications for the QFX10002 DC power cables.

Warning:

For field-wiring connections, use copper conductors only.

Warning:

Power cables must not block access to QFX10002 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.

Either the power cord is unplugged or a major error is detected in the power supply. Examples of a major error are: power supply failure, an over voltage protection error, an over current protection error, or a fan failure.

  • If the power cord is unplugged or missing, reattach the power cord appropriate for your country.

  • If a major error is occurring, 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.
