System Software
EX Series switches use the Junos operating system (OS), which provides Layer 2 and
Layer 3 switching, routing, and security services. Junos OS is installed on a EX4600
switch’s 8-gigabyte (GB) internal flash drive. The same Junos OS code base that runs
on EX4600 switches also runs on all Juniper Networks QFX Series devices, and J Series,
M Series, MX Series, and T Series routers.
For more information about which features are supported on QFX Series devices, see
QFX Series Software Features Overview.
You manage the switch using the Junos OS command-line interface (CLI), accessible
through the console and out-of-band management ports on the device.

EX4600 Switch Models
The EX4600 switches have a base configuration of 24 small form-factor pluggable plus
(SFP+) ports and 4 quad small-form-factor pluggable (QSFP+) that can be expanded
by using expansion modules. All switches are available with either AC or DC power supply
and with either airflow-in or airflow-out cooling. In legacy switches, or switches with an
LCD, this air flow is called front-to-back and back-to-front.
Table 3 on page 5 lists the EX4600 switch models.
