Juniper QFX3000-G QFabric, Deployment Manual, Page: 283 / 652

•
Install your QFabric system hardware (Director group, Interconnect devices, and Node
devices). For more information, see
“Installing and Connecting a QFX3100 Director
Device” on page 143 , “Installing and Connecting a QFX3008-I Interconnect Device” on
page 155 , “Installing and Connecting a QFX3600 or QFX3600-I Device” on page 193 , and
“Installing and Connecting a QFX3500 Device” on page 211 .
• Install your Virtual Chassis hardware (EX4200 switches). For more information, see
Installing and Connecting an EX4200 Switch .
•
Create two Virtual Chassis of eight EX4200-24F switches each. For more information,
see
Configuring an EX4200, EX4500, or EX4550 Virtual Chassis (CLI Procedure) .
• Interconnect the two Virtual Chassis switches using the 10-Gigabit Ethernet SFP+
uplink ports. For more information, see
“Interconnecting Two Virtual Chassis for
Fiber-Based QFX3000-G QFabric System Control Plane Redundancy” on page 245 .
•
Ensure that 1-Gigabit Ethernet 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 appropriate fiber-optic cables (see “Interface Specifications for
SFP, SFP+, and QSFP+ Transceivers for the QFX Series” on page 104 ).
• 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 ).
•
Use Table 73 on page 257 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 74 on page 256 and Table 73 on page 257 . Interconnect
devices IC2 and IC3 are not shown in Figure 74 on page 256 and describe the
port mappings for the optional third and fourth Interconnect devices
