EX4600 Switch Hardware Guide
4
The EX4600-40F is a 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable
(SFP+) top-of-rack switch with 24 fixed SFP+ access ports and 4 Quad SFP+ (QSFP+)
high-speed uplinks.
In addition, the EX4600-40F has two module bays for optional expansion modules. The
EX4600 supports two expansion module to increase port density:
QFX-EM-4Q–Adds a total of four additional QSFP+ ports to the chassis. When fully
populated with QFX-EM-4Q Expansion Modules, the EX4600 is equivalent to 72
10-Gigabit Ethernet interfaces (24 + 16 + 16 + 16) or 40 1-Gigabit Ethernet interfaces
(24 + 8 +8). See Figure 1 on page

EX4600-EM-8F–Adds a total of eight additional SFP+ ports to the chassis. When fully
populated with EX4600-EM-8F Expansion Modules, the EX4600 is equivalent to 56
10-Gigabit Ethernet interfaces (24 + 16 + 8 + 8). See

The EX4600 switch can be used as:
A standalone switch.
A master, backup, or "linecard" member in a Virtual Chassis with EX4600 switches or
with EX4300 switches. An EX4600 Virtual Chassis allows you to interconnect a mixture
of up to ten switches into one logical device and manage the device as a single chassis.
An EX4600 Virtual Chassis is cabled in a ring topology.
