Juniper EX4600, Руководство по оборудованию

Страница: 23 / 230

BEST PRACTICE: Use the EX4600 as a master and backup RE in the Virtual
Chassis because the EX4300 does not support Power over Ethernet (PoE),
802.1x, and Link Layer Discovery Protocol (LLDP).
Eligible product numbers for Virtual Chassis members are:
• EX4600
• EX4300 as a linecard
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.
