QFX Series devices support using RJ-45 patch cables to interconnect the copper-based
QFabric system control plane. The RJ-45 patch cables connect to 1000BASE-T ports on
the network modules in the QFX3100 Director device and the management ports in the
QFX3500 Node device, QFX3600 Node device, and QFX3600-I Interconnect device.
QFX5100 Node devices and the QFX5100-24Q Interconnect devices connect using a
1000BASE-T port and a 1000BASE-T SFP module (Juniper model number
C1
QFX-SFP-1GE-T) installed in the the SFP management Ethernet cage
SKUs have an additional SFP management port (second
In the QFX3008-I Interconnect device Control Board, the RJ-45 patch cables are used
with 1000BASE-T SFP modules (Juniper model number QFX-SFP-1GE-T) installed in
the SFP+ ports.
