QFX5130 System Overview

The Juniper Networks® QFX5130 line of Switches is a high-radix, high-density, 1-U platform suitable for today’s data centers. The four options, QFX5130-32CD/QFX5130E-32CD, QFX5130-48C, and QFX5130-48CM are a perfect choice for leaf, border-leaf, and spine roles within IP networks, as well as Ethernet VPN fabrics. For large public cloud providers—early adopters of high-performance servers to meet increasing workload—the QFX5130-32CD/QFX5130E-32CD supports very large, dense, and fast 400-Gigabit Ethernet (GbE) IP fabrics based on Internet-scale technology. The QFX5130-48C and QFX5130-48CM switches support dense 100-GbE SFP56-DD ports.When enterprise data center customers transition their server farms from 10GbE to 25GbE, the QFX5130 switch provides radix-native 100GbE/400GbE Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) with lower power and space requirements..

With additional Remote Direct Memory Access over Converged Ethernet version 2 (RoCEv2) capabilities, QFX5130 is suitable in IP storage deployments. Instead of deep buffer switching, QFX5130 uses quality of service (QoS) mechanisms such as priority-based flow control–DiffServ code point (PFC-DSCP) and explicit congestion notification (ECN) to deliver high performance for storage workload. Support for high-power 400G-ZR and 400G-ZR-M optics makes this line of switches suitable for edge and Data Center Interconnect (DCI) use cases.

QFX5130 Switch Description

The QFX5130 line of Switches includes four compact 1-U platforms—QFX5130-32CD/QFX5130E-32CD, QFX5130-48C, and QFX5130-48CM. Both the switches provide high speeds, high densities, and a rich set of Junos® OS Evolved features.

The Juniper Networks QFX5130-32CD/QFX5130E-32CD Switch is a next-generation, fixed-configuration spine-and-leaf switch featuring:

32 400-G quad small form-factor pluggable–double density (QSFP-DD) ports in 1-U form factor
Up to 25.6 terabit per second (Tbps) (bidirectional)/5.68 billion packets per second (Bpps) throughput
Enhanced scale up to 1.24 million routes, 80,000 firewall filters, and 160,000 media access control (MAC) addresses

Using breakout cables, each of the 32 400GbE QSFP-DD ports can be broken into four 100/25/10GbE ports, increasing the total number of supported 100/25/10 GbE ports per switch to 128 ports.

The QFX5130-32CD/QFX5130E-32CD offers 32 400GbE ports in a low-profile 1-U form factor. The high-speed ports support a wide variety of port speeds ranging from 10Gbps to 400 Gbps.

An Intel Xeon D-1500 processor drives the QFX5130 control plane that runs the Junos OS Evolved software and supports 32-GB memory (16GBx2) of DDR4.The Junos OS Evolved software image is stored on two internal 50-GB solid-state drives (SSDs).

The QFX5130-32CD/QFX5130E-32CD is available with either ports-to-field-replaceable units or field-replaceable units-to-ports airflow and with AC or DC power supplies.

System Software

The Junos OS Evolved software that runs on QFX5130 Switches 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 supported on the QFX5130, see Feature Explorer.

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

The QFX5130-48C switch is supported from Junos OS 23.4R1-S1-EVO; the QFX5130-48CM switch is supported from 23.4R2-S1-EVO. The QFX5130-32CD switch is supported from Junos OS 20.3R1-EVO, the QFX5130E-32CD is supported from Junos OS 23.4R2-EVO.

QFX5130 Component Redundancy

The following hardware components provide redundancy on a QFX5130 switch:

QFX5130 power supplies—The QFX5130 switches have two power supplies. Each power supply provides power to all the components in the switch, ensuring full power redundancy to the device. 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 can continue to operate without interruption.

To provide power redundancy to the switch, you must install both the power supplies. Connect power source feed A to one power supply and power source feed B to the second power supply.
QFX5130-32CD/QFX5130E-32CD cooling system—Each of the QFX5130 -32CD/QFX5130E-32CD switch models has six fan modules and can operate with one fan module not in operation (5+1 redundancy). The failure of more than one fan module can cause the QFX5130 temperature to exceed the desired threshold, triggering chassis alarms and switch shutdown.
QFX5130-48C and QFX5130-48CM cooling system—The QFX5130-48C and QFX5130-48CM switches have six fan modules and support redundancy only at the rotor level. You can continue to operate the switch with just one rotor of a fan module. If more than one rotor of any fan module fails and is unable to keep the QFX5130-48C /QFX5130-48CM switch within desired temperature thresholds, chassis alarms occur and the QFX5130-48C/QFX5130-48CM switch shuts down.

QFX5130 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5130 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.

CAUTION:

Though QFX5130 switches continue 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 the chassis from overheating.

Table 3 lists the FRUs for the QFX5130 Switch and actions to take before removing them.

Table 3: FRUs in a QFX5130 Switch
FRU	Required Action
Power supply units	None.
Fan modules	None.
Optical transceivers	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.

Note:

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure to register this information can result in significant delay in receiving replacement parts when required. This note does not apply if you replace existing components with the same type of component.
