Removing an Expansion Module from a QFX5100 Device
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).
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.
Ensure that you have the following parts and tools available:
ESD grounding strap
Phillips screwdriver, number 2
A replacement optional module or cover panel
An antistatic bag or antistatic mat
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.
You must take the QFX5100-24Q-AA switch offline, before replacing the QFX-PFA-4Q expansion module.
We recommend that you install either a replacement optional module or a cover panel in the empty module slot to avoid chassis overheating and dust accumulation.
To remove an expansion module from the switch (see Figure 1 and Figure 2):
Figure 1 shows removing a QFX-EM-4Q expansion module from the port panel of a QFX5100-24Q device.

Figure 2 shows removing a QFX-PFA-4Q expansion module from the port panel of a QFX5100-24Q-AA switch.
You must take the QFX-PFA-4Q offline before replacing it.
