Hold the handle and gently pull the expansion module toward you and out of the
3.
module slot.
Place the expansion module in an antistatic bag or on an antistatic mat placed on a
4.
flat, stable surface.
If you are not replacing the expansion module with an optional module, install the
5.
cover panel over the slot.
NOTE: After you have removed an expansion module, wait for at least 5
seconds before you install an expansion module. If you do not wait for at
least 5 seconds, the interfaces on the expansion module might not come
up.
Figure 33 on page 174 shows removing a QFX-EM-4Q expansion module from the port

The fan modules in an EX4600 switch 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.
CAUTION: Replace a failed fan module with a new fan module within 1 minute
of removal to prevent chassis overheating. Before removing the fan module,
ensure you have a replacement fan module at hand.
