Cable Specifications for Copper-Based Control Plane Connections for the QFabric System
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
C1 and a 1000BASE-T
SFP module (Juniper model number QFX-SFP-1GE-T) installed in the the
SFP management Ethernet cage
C0. Some QFX5100
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.
For information about the QFX-SFP-1GE-T SFP module, see the Hardware Compatibility Tool.
