Determining Interface Support for an EX4600 Switch
The 24 small form-factor pluggable (SFP) network ports on EX4600 switches support 10-Gigabit
Ethernet transceivers and direct-aach copper (DAC) cables. The switch also supplies four quad small
form-factor pluggable plus (QSFP+) ports for use as uplinks. These 40-Gigabit Ethernet ports support
QSFP+ transceivers, QSFP+ DAC cables, and DAC breakout cables (DACBO). Each QSFP+ port on an
EX4600 switch can be congured to operate as 10-Gigabit Ethernet interface by using a breakout cable
or as a single 40-Gigabit Ethernet interface. The ports on an EX4600 switch are disabled by default. You
enable a port through the CLI.
Figure 23 on page 57 shows the dierent ports available on the EX4600 switch.
