The second QFX3100 Director device provides redundancy for the control plane and
management network.
Before you begin to connect QFX3100 Director devices in a Director group:
•
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 .
NOTE: For a copper-based QFX3000-M QFabric system control plane
network, use QFX3100 Director devices with RJ-45 network modules
installed. For a fiber-based control plane network, use QFX3100 Director
devices with SFP network modules installed.
• Ensure that you have appropriate transceivers and cables available. For cable
specifications, see
“Cable Specifications for Copper-Based Control Plane Connections
for the QFabric System” on page 126 and “Interface Specifications for SFP, SFP+, and
QSFP+ Transceivers for the QFX Series” on page 104 .
CAUTION: The redundant patch cables interconnecting the Director devices
are critical links required for the operation of the Director group. The two
inter-Director device links must remain connected when the Director devices
are online. Although a single inter-Director device can lose a link and regain
its connection, the loss of both inter-Director device links causes one of the
Director devices to become isolated from the Director group. In
Figure 61 on page 228 through Figure 63 on page 229 , these redundant patch
cables are shown in red and connect port 3 to port 3 .
To connect QFX3100 Director devices in a Director group (see Figure 61 on page 228 ):
WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to transceivers emit laser light that can damage your eyes.
1.
Connect the port labeled
3
on the first network module on one of the Director devices
to the corresponding port (labeled
3
) on the first network module on the second
Director device.
2.
Connect the port labeled 3 on the second network module on one of the Director
devices to the corresponding port (labeled 3 ) on the second network module on the
second Director device.
