Expansion Modules for the EX4600
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.
