Juniper QFX3500, Hardware Documentation

Page: 166 / 669

NOTE: Ports Q1 through Q3 support four of the 10-Gigabit Ethernet interfaces. Together, the
three QSFP+ ports provide up to 12 10-Gigabit Ethernet interfaces. Port Q0 also supports
10-Gigabit Ethernet interfaces, but the number of interfaces supported depends on the release
of Junos OS running on the switch. Some Junos OS releases support three 10-Gigabit Ethernet
interfaces, others support four. See the topic on Channelizing Interface for your specific release.
Figure 58 on page 142 shows the uplink ports and lists the interfaces created on each port when they are
configured as 10-Gigabit Ethernet interfaces.

If your QFX3500 device has an SFP management board instead of the 1000BASE-T RJ-45 management
board, you can use the SFP transceivers to connect the QFX3500 device to a management network, or
the control plane and management network of a QFabric system. The 1000BASE-SX Gigabit Ethernet SFP
module (QFX-SFP-1GE-SX) is supported in the SFP management ports in the following software releases:
•
Junos OS 12.1X49-D1 or later for the QFX3500 device as a standalone switch
•
Junos OS 12.2X50-D10 or later for the QFX3500 Node device in a QFabric system
You can find information about the optical transceivers supported on your Juniper device by using the
Hardware Compatibility Tool. In addition to transceiver and connection type, the optical and cable
characteristics–where applicable–are documented for each transceiver. The Hardware Compatibility Tool
enables you to search by product, displaying all the transceivers supported on that device, or category, by
interface speed or type. The list of supported transceivers for the QFX3500 is located at
https://pathfinder.juniper.net/hct/product/#prd=QFX3500 .
