Connecting a QFX3600 Node Device to a QFX3008-I Interconnect Device
Copyright © 2018, Juniper Networks, Inc.
To form the data plane in a QFX3000-G QFabric system, you connect the QSFP+ uplink
ports (labeled through
Q0
16-port QSFP+ front cards in a QFX3008-I Interconnect device.
NOTE: By default, four ports (labeled
40-Gbps uplink connections between your QFX3600 Node device and your
Interconnect device. Optionally, you can choose to configure the first eight
ports (labeled
Q0
the Port Type on QFX3600 Node Devices" on page
CAUTION: For redundancy, each QFX3600 Node device must be connected
to each QFX3008-I Interconnect device. For example, if you have two
QFX3008-I Interconnect devices, then at least one uplink port on each
QFX3600 Node device must be connected to each QFX3008-I Interconnect
device. If you are connecting four uplink ports to two QFX3008-I Interconnect
devices, we recommend connecting two uplink ports to each Interconnect
device, each to a different front card. If you are connecting eight uplink ports
to two QFX3008-I Interconnect devices, we recommend connecting four
uplink ports to each Interconnect device, each to a different front card.

Ensure that you have taken the necessary precautions for safe handling of lasers (see
"Laser and LED Safety Guidelines and Warnings for the QFX Series" on page
Ensure you have installed QSFP+ transceivers in each port you are using. See
