QFX5240 Switch Descripon
The Juniper Networks® QFX5240 Switches are high-density devices that you can use as end-of-row,
leaf or spine devices in an IP fabric architecture. These 2-U xed-conguraon switches oer up to 64
800-Gigabit Ethernet (GbE) ports through two models—the QFX5240-64OD and the QFX5240-64QD.
The QFX5240-64OD oers 64 800-Gbps octal small form factor pluggable (OSFP) ports and 2 10-Gbps
SFP+ ports. The QFX5240-64QD switch has 64 800-Gbps quad small form-factor pluggable - double
density (QSFP-DD) ports and 2 10-Gbps SFP+ ports. With a bandwidth of 51.2 terabits per second
(Tbps), the QFX5240 is an opmal choice for shallow buer plaorms for the spine role in the data
center fabric. The QFX5240 switches use the high-radix class TH5 - BCM78900 chip, which is a
dedicated ASIC for high-bandwidth network switching devices.
An Intel 4-core 2.2-GHz Ice Lake processor drives the QFX5240 control plane, which runs the Junos OS
Evolved soware. The Junos OS Evolved soware image is stored on two internal 480-GB Non-Volale
Memory Express (NVMe) solid-state drives (SSDs).
