QFX3000-G QFabric System Hardware Documentation
Adding or Replacing a Node Device in a QFabric Node Group
Before You Begin
578
Use this set of procedures to add or replace a node device in a:
Network Node group
Server Node group
Redundant server Node group
The Director group in a 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 the device to the QFabric system inventory.
Eligible devices in a Node group are QFX5100-48S, QFX5100-48T, QFX5100-24Q,
QFX3600, and QFX3500. When replacing a Node device, it is not necessary to replace
the existing device with the same switch model.
CAUTION: The QFabric system might experience data loss when replacing
a device in a server Node group during this procedure. Devices in redundant
server Node groups and Network Node groups should not experience data
loss.

Adding a New Node Device to a Node Group in a QFabric System on page 581
Before adding a new device or replacing an existing node device, review the following
checklist:
If the switch you plan to install as a Node device was previously used as a standalone
switch and had advanced feature licenses installed, you can transfer those licenses
to a new device. Contact your Juniper Networks sales representative for more
information.
Ensure interfaces are grouped into a LAG interface for rerouting of traffic when a device
is unavailable.
Ensure all devices have an alias name configured before starting the replacement
process. See Gaining Access to the QFabric System Through the Default Partition and
Configuring Aliases for the QFabric System.
TIP: By default the Node devices are identified using their hardware serial
number. Aliases take the place of the hardware serial numbers and help
to simplify configuration tasks. The chassis serial number ID label is located
in different locations depending upon the QFX switch model. See the
hardware guide for your QFX switch model.
