Installing an Expansion Module in an EX4600 Switch
The EX4600 switch allows up to two expansion modules to be added to the port panel
to increase port density. The EX4600 switch holds two bays of expansion modules that
can be mixed and matched as desired. The supported modules are:
• QFX-EM-4Q–Each module adds four Quad Enhanced Small Form-Factor Pluggable
(QSFP+) ports
•
EX4600-EM-8S–Each module adds eight 10 Gigabit RJ-45 ports
Both the QFX-EM-4Q and the EX4600-EM-8S are hot-removable and hot-insertable
field-replaceable units (FRUs). You can remove and replace these modules without
powering off the switch or disrupting switch functions.
NOTE: When an expansion module is installed in the switch or an existing
expansion module is replaced with another expansion module, the switch
detects the ports on the expansion module. The switch creates the required
interfaces when transceivers are installed in these ports.
Before you begin installing an expansion module in the switch, ensure that you have taken
the necessary precautions to prevent electrostatic discharge (ESD) damage (see
“Prevention of Electrostatic Discharge Damage” on page 120 ).
Ensure that you have the following parts and tools available:
