QFX5130-32CD System Overview

The QFX5130 line of switches offers a high-density, cost-optimized 1-U, 400GbE fixed configuration ideal for environments where cloud services are added. The QFX5130 line offers an excellent solution for environments that require 100-Gigabit Ethernet and 400-Gigabit Ethernet speeds. With 12.8-Tbps bandwidth, the QFX5130 is optimally designed for spine-and-leaf deployments in enterprise, service provider, and cloud provider environments.

QFX5130-32CD Switch Description

The QFX5130-32CD offers 32 ports of 400-Gigabit Ethernet in a low-profile 1-U form factor. The high-speed ports support a wide variety of port speeds ranging from 10Gbps to 400Gbps.

An Intel Xeon D-1500 processor drives the QFX5130 control plane, which runs the Junos OS Evolved software. The Junos OS Evolved software image is stored on two internal 50-GB solid-state drives (SSDs).

The QFX5130-32CD is available with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

Benefits of the QFX5130-32CD Switch

  • Enables data center re-architecture with flattened pods that slash switch hop latency.

  • Enables a fast response by demanding applications, such as those employed in financial exchanges by reducing intracluster switch latency.

  • Support for VXLAN as a Layer 2 (L2) or Layer 3 (L3) gateway and Open vSwitch Database (OVSDB) protocol as an L2 gateway.

  • Allows current Junos OS users to seamlessly migrate to Junos OS Evolved software. With Junos OS Evolved, you can run Linux using your familiar Junos OS CLI, and run third-party Linux applications with Juniper Extension Toolkit (JET) API support, telemetry support for monitoring the DC network, and support for module-level in-service software upgrade (ISSU).

  • Saves you energy costs by highly reducing power consumption per Gbps of network traffic passing through the switch.

System Software

The Junos OS Evolved software that runs on the QFX5130-32CD Switch provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS Evolved is installed on the switch solid-state drive (SSD).

For more information about the features are supported on QFX5130-32CD, see Feature Explorer.

You manage the switch using the Junos OS CLI, accessible through the console and out-of-band management ports on the device.

The QFX5130-32CD is supported on Junos OS Evolved Release 20.3R1 and later.

QFX5130-32CD Component Redundancy

The following hardware components provide redundancy on a QFX5130-32CD switch:

  • QFX5130-32CD power supplies—The QFX5130-32CD switches have two power supplies. Each power supply provides power to all components in the switch. If two power supplies are installed, the two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply takes on the additional electrical load, so that the switch continues to operate without interruption.

    To provide power redundancy to the system, both power supplies must be installed. Connect power source feed A to one power supply and power source feed B to the second power supply.

  • QFX5130-32CD cooling system—The QFX5130-32CD switch models have six fan modules and can operate with one fan not in operation (5+1 redundancy). If more than one fan module fails and is unable to keep the QFX5130-32CD within the desired temperature thresholds, chassis alarms occur and the QFX5130-32CD switch can shut down.

QFX5130-32CD Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5130-32CD device FRUs are hot-insertable and hot-removable: you can remove and replace the FRUs without powering off the switch or disrupting the switching function.


Though the QFX5130-32CD switch continues to operate with only one power supply running, we advise replacing failed power supplies and fan modules as quickly as possible to protect against another failure. Replace a failed power supply with a new power supply within 3 minutes of removal to prevent chassis overheating.

Table 2 lists the FRUs for the QFX5130-32CD device and actions to take before removing them.

Optical transceivers

None. We recommend that you disable the interface using the set interfaces interface-name disable command before you remove the transceiver. See Disconnect a Fiber-Optic Cable.


If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
