Expansion Modules for the EX4600 on page 19
The EX4600 switch has two bays on the port panel for optional expansion modules. The
EX4600 supports two expansion modules to increase port density:
EX4600-EM-8F, which provides 8 additional 10-Gigabit Ethernet Enhanced Small
Form-Factor Pluggable (SFP+) ports.
QFX-EM-4Q, which provides 4 additional 40-Gigabit Quad SFP+ (QSFP+) ports.
The EX4600 is configured for the QFX-EM-4Q by default, but any combination of the
two modules is supported. Expansion modules can be hot-inserted or hot-removed.
However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the
new configuration causes the interfaces to temporarily go down. Likewise when an
EX4600-EM-8F is running on the EX4600 and it is swapped with a QFX-EM-4Q, the
interfaces temporarily go down, which can cause a short disruption in traffic.
NOTE: Expansion modules and transceivers are not shipped with the switch
and must be ordered separately.
