NOTE: When you install the QFX-PFA-4Q expansion module in a
QFX5100-24Q-AA switch and reboot the switch, the two NIC ports in the NIC
inside the QFX5100-24Q-AA switch are enabled automatically. When you
install other expansion modules (QFX-EM-4Q or EX4600-EM-8F), the NIC
ports are enabled only when an EX4600-EM-8F is installed in slot 2 (QIC1),
that is, the expansion module slot located on your right as you face the
QFX5100-24Q-AA. To verify that the NIC ports are enabled, run the show
interfaces terse command. For a QFX-PFA-4Q, the NIC interface names are
displayed in the command output as, xe-0/0/40 and xe-0/0/41. For an
EX4600-EM-8F installed in slot 2 (QIC1), the NIC interfaces are displayed as
xe-0/0/24 and xe-0/0/25.
NOTE: If you have a Juniper Care service contract, register any addition,
change, or upgrade of hardware components at
https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure
to do so can result in significant delays if you need replacement parts. This
note applies if you change the type of power supply or add a new type of
expansion module. It does not apply if you replace these components with
the same type of component.

Removing an Expansion Module from a QFX5100 Device
The expansion modules used in QFX5100-24Q and QFX5100-24Q-AA devices are
hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and
replace them without powering off the switch or disrupting switch functions.
NOTE: You must take the QFX5100-24Q-AA switch offline, before replacing
the QFX-PFA-4Q expansion module.
Before you begin removing an expansion module from the switch:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 263).
•
If there are any transceivers installed in the expansion module, remove them before
you remove the expansion module. For instructions on removing transceivers, see
“Removing a Transceiver from a QFX Series Device” on page 213.
Ensure that you have the following parts and tools available:
