Juniper QFX Series User Manual

Adding or Replacing a QFX3008-I Interconnect Device in a QFX3000-G QFabric System
The Director group in a QFX3000-G QFabric system automatically recognizes when
devices are added or replaced in the QFabric system. The Director group sends each
device its own portion of the Junos OS configuration and adds them to the QFabric system
inventory. You can install up to four QFX3008-I Interconnect devices in a QFX3000-G
QFabric system.
CAUTION: The QFX3000-G QFabric system might experience data loss
duringthis procedure.Data will continue tobe forwardedthroughQFX3008-I
Interconnect devices that are not powered down during this procedure, but
available network bandwidth is reduced.
Before you add or replace a QFX3008-I Interconnect device in a QFX3000-G QFabric
system:
•
Ensure that you havetaken the necessary precautions to prevent electrostatic discharge
(ESD) damage. See “Prevention of Electrostatic Discharge Damage” on page 192.
•
Ensure that you do not need to forward traffic through the device.
•
If possible, install the replacement QFX3008-I Interconnect device and connect it to
power to minimize the amount of time it will take to replace the device.
Ensure that you have the following parts and tools available to power off the device:
•
An ESD grounding strap
•
An external management device such as a PC
•
An RJ-45 to DB-9 rollover cable to connect the external management device to the
console port
To add or replace a QFX3008-I Interconnect Device in a QFX3000 QFabric system:
1. If you are replacing a device, power off the QFX3008-I Interconnect device that you
will remove from the QFabric system. See “Powering Off a QFX3008-I Interconnect
Device” on page 296.
2. Uncable the old device. Label each cable as you remove it, so that you can easily
connect the replacement Interconnect device.
3. Connect the new QFX3008-I Interconnect device to the QFX3000-G QFabric system
control plane network. See “Connecting a QFX3008-I Interconnect Device to the
Control Plane Network” on page 278.
