The Juniper Networks QFX3500 device is a high-speed, multipurpose switch especially designed for
next-generation data centers. The QFX3500 can be configured as a standalone switch, a Node device in
a QFabric system, or as a member of a QFX Virtual Chassis.
Forty-eight 10-Gbps access ports in the device use small form-factor pluggable plus (SFP+) transceivers
and operate by default as 10-Gigabit Ethernet interfaces. Optionally, you can choose to configure up to
12 of the ports as 2-Gbps, 4-Gbps, or 8-Gbps Fibre Channel (FC) interfaces, and up to 36 of the ports as
1-Gigabit Ethernet interfaces. When used as a standalone switch, four 40-Gbps uplink ports in the device
use quad small form-factor pluggable plus (QSFP+) to four SFP+ copper breakout cables to support an
additional 15 10-Gigabit Ethernet interfaces.
QFX3500 devices can function as a Fibre Channel over Ethernet (FCoE)-FC gateway or as an FCoE transit
switch. FCoE is a method of supporting converged FC and Ethernet traffic on a data center bridging (DCB)
network by encapsulating unmodified FC frames in Ethernet to transport the FC frames over the physical
Ethernet network.
In a QFabric system, a QFX3500 device functions as a Node device, connected to a QFabric system through
40-Gbps uplink ports to a Juniper Networks QFX3008-I or QFX3600-I Interconnect device. Together, the
