•
Interconnect the two Virtual Chassis switches using the 10-Gigabit Ethernet SFP+
uplink ports. For more information, see
“Interconnecting Two Virtual Chassis for
Copper-Based QFX3000-G QFabric System Control Plane Redundancy” on page 225 .
•
Ensure that 1000BASE-T SFP transceivers are installed in port
0
and port
1
on both
Control Boards for each QFX3008-I Interconnect device (see Installing a Transceiver
in a QFX Series Device ). For a list of supported transceivers and required cables, see
“Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for the QFX Series”
on page 104
.
•
Ensure that you have installed 1-Gigabit Ethernet SFP transceivers in the ports you are
using on each EX4200 switch (see
Installing a Transceiver in an EX Series Switch ). For
a list of supported transceivers, see Pluggable Transceivers Supported on EX4200
Switches .
•
Ensure that you have four RJ-45 patch cables available for each Interconnect device.
For cable specifications, see
“Cable Specifications for Copper-Based Control Plane
Connections for the QFabric System” on page 126 .
• Use Table 67 on page 236 to determine the QFX3008-I Interconnect device-to-Virtual
Chassis port mappings. Specific ports have been reserved on the Virtual Chassis to
connect to each of the QFX Series device types. Such design simplifies installation and
facilitates timely deployment of a QFabric system.
NOTE: The two Control Boards in each Interconnect device are labeled
CB0
and
CB1
in Figure 65 on page 235 and Table 67 on page 236 . Interconnect
devices IC2 and IC3 are not shown in Figure 65 on page 235 and describe
the port mappings for the optional third and fourth Interconnect devices
