QFX5200 System Overview

QFX5200-32C and QFX5200-32C-L Hardware

The QFX5200-32C and QFX5200-32C-L are compact 1 U standalone switches that provides a line rate configuration packet performance, very low latency, and a rich set of Layer 3 features. The routing engine and control plane are driven by the 1.8 Ghz quad-core Intel CPU with 16 GB of memory and two 32 GB solid-state drives (SSD) for storage. The QFX5200-32C models run standard Junos Operating System (OS); the QFX5200-32C-L models run Junos OS Evolved.

As shown in Figure 1, the QFX5200-32C and QFX5200-32C-L are 100 Gigabit Ethernet top-of-rack switches that support both quad small form-factor pluggable (QSFP+), 100-Gbps QSFP+ (QSFP28) transceivers, and break out cables in the 32 QSFP28 sockets. The ports 0 through 31 can be configured as either uplinks or as access ports. The QSFP28 ports are configured as 100-Gigabit Ethernet ports by default, but can also be configured to speeds of 50, 40, 25, or 10-Gigabit Ethernet.

The QFX5200-32C and QFX5200-32C-L comes standard with redundant fans and redundant power supplies. Switches can be ordered with either ports-to-FRUs or FRUs-to-ports airflow. The QFX5200-32C is available with AC or DC power supplies; the QFX5200-32C-L is available only with AC power supplies.

The QFX5200-32C-L is supported as a standalone switch (Junos OS Evolved Release 18.3R1 only).

The QFX5200-32C can be used as:

• A standalone switch (Junos OS Release 15.1X53-D30 and later).

• A member in an all QFX5200-32C Virtual Chassis (Junos OS Release 17.3R2 and later).

  You can create an all QFX5200-32C Virtual Chassis with up to three members. The QFX5200-32C is used in all three member roles: primary RE, backup RE, and line card.

• A satellite device in a Junos Fusion Provider Edge system (Junos OS Release 18.1R2 and later). A switch in standalone mode must be converted to a satellite device.

QFX5200-48Y Hardware

The QFX5200-48Y is a flexible switch for environments with the need for native 25 Gbps port speeds. The 48 small form-factor pluggable 28 (SFP28) ports support 10 Gbps or native 25 Gbps speeds, and the 6 QSFP28 support either 40 Gbps or 100 Gbps speeds. The 48 SFP28 default to 10 Gigabit Ethernet and must be configured in groups of four ports to support 25 Gigabit Ethernet. You can alternate each group of four ports with either 10 Gbps or 25 Gbps across the 48 ports. For details on configuring the SFP28 ports, see QFX5200-48Y Port Panel.

The 6 QSFP28 ports auto-detect the optic speed of transceivers and set the port speed accordingly. The six QSFP28 ports can be channelized when configured to 40 Gigabit Ethernet to 4 independent 10 Gigabit Ethernet ports.

The routing engine and control plane of the switch are driven by the 2.20 Ghz quad-core Intel CPU with 16 GB of memory and a 32 GB solid-state drive (SSD) for storage. The QFX5200-48Y provides an aggregate throughput of 3.6 Tbps (full duplex).

As shown in Figure 2, the QFX5200-48Y has a 1 U form factor and comes standard with redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DCpower supplies.

The QFX5200-48Y is supported on Junos OS Release 18.1R1 and later.
