Juniper QFX3500-48S4Q-ACR QFX Series managed rack-mountable switch
The Juniper Networks QFX3500-48S4Q-ACR 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 QFX3500 Node devices and QFX3008-I or QFX3600-I Interconnect devices form a multistage, nonblocking switch fabric that provides a high-performance, low-latency, unified interconnect solution for next-generation data centers.
The QFX3500 Node devices and Interconnect devices are connected to Juniper Networks QFX3100 Director devices in an out-of-band management network through Juniper Networks EX4200 Ethernet Switches. The QFX3100 Director devices present the QFabric system devices as a single network entity, which enables simplified management of your data center using the Junos OS command-line interface (CLI).
In a QFX Virtual Chassis, the QFX3500 device can participate with other QFX3500 devices and QFX3600 devices in a ring topology with up to 10 members.
In a QFX5100 Virtual Chassis Fabric, the QFX3500 device can participate as a leaf device. Up to a total of 20 devices can participate in the QFX5100 Virtual Chassis Fabric.
The compact QFX3500 device is 1 rack unit (1 U) in size and designed to fit in industry-standard 19-inch rack-mount enclosures.
The front panel of the QFX3500 chassis has an LCD panel that displays the device hostname and the number of active alarms. See Front Panel of a QFX3500 Device. The rear panel has 48 10-Gbps access ports and 4 40-Gbps uplink ports. See Rear Panel of a QFX3500 Device.
Up to 48 of the access ports can be used for SFP+ transceivers or SFP+ direct attach copper cables. You can use 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port. You can use 2-Gbps, 4-Gbps, or 8-Gbps Fibre Channel SFP+ transceivers in ports 0 through 5 and ports 42 through 47.
Up to 36 of the access ports can be used for SFP transceivers. Gigabit Ethernet SFP transceivers can be used in ports 6 through 41.
QSFP+ Uplink Ports
The QFX3500 device has four uplink ports (Q0 through Q3) that support up to four QSFP+ transceivers, as well as QSFP+ DAC or DAC breakout cables. See Determining Interface Support for the QFX3500 Device.
When the QFX3500 device is used as part of a QFabric system, these uplink ports are used to connect the QFX3500 Node device to QFX3008-I or QFX3600-I Interconnect devices. See Connecting a QFX3500 Node Device to a QFX3008-I Interconnect Device or Connecting a QFX3500 Node Device to a QFX3600-I Interconnect Device.
When the QFX3500 device is used as a standalone switch, these uplink ports are configured by default as 15 10-Gigabit Ethernet interfaces. Another option for these ports is to configure one or more of the ports as 40-Gigabit Ethernet interfaces.
