EX3300 Switches Hardware Overview

Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers and SRX Series services gateways.

Juniper Networks EX3300 Ethernet Switches provide connectivity for low-density environments.

EX3300 Switches First View on page 3

•

Uplink Ports on page 4

•

Power over Ethernet Plus Ports on page 4

EX3300 Switches First View

EX3300 switches provide:

•

Either 24 or 48 built-in network ports with 10/100/1000BASE-T Gigabit Ethernet connectors (ports labeled 0 through 23 or 0 through 47)

•

Four uplink ports (ports labeled 0 through 3)

•

Virtual Chassis capability—You can connect up to ten EX3300 switches together to form one unit that you manage as a single chassis, called a Virtual Chassis.

•

Power over Ethernet Plus (PoE+) on all network ports (in PoE+-capable models only)

EX3300 Switch Hardware Guide

Uplink Ports

Each EX3300 switch has four autosensing uplink ports. You can use the uplink ports on the switch to:

•

Connect an access switch to a distribution switch

•

Interconnect member switches of a Virtual Chassis

The uplink ports labeled 0 and 1 (interfaces ge-0/1/0 and ge-0/1/1 or xe-0/1/0 and

xe-0/1/1) are configured by default as network ports. To use uplink ports 0 and 1 to

interconnectVirtual Chassis members, you must configure them as Virtual Chassis ports (VCPs).

The uplink ports labeled 2 and 3 (interfaces ge-0/1/2 and ge-0/1/3 or xe-0/1/2 and

xe-0/1/3) are configured by default as VCPs. You can use these uplink ports to

interconnect Virtual Chassis members. To use uplink ports 2 and 3 as network ports, you must configure them as network ports.

The uplink ports support SFP and SFP+ transceivers. For a list of supported transceivers, see “Pluggable Transceivers Supported on EX3300 Switches” on page 71.

Power over Ethernet Plus Ports

EX3300 switches are available in models with or without PoE+ capability. Models that support PoE+ provide that support on all network ports.

PoE+ ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables, thus eliminating the need for separate power cords for those devices.

EX3300 Switch Models

The EX3300 switch models are available:

•

With 24 or 48 network ports

•

With or without PoE+ capability

NOTE: IEEE 802.3af and IEEE 802.3at powered devices require category 5

or higher Ethernet cables.

•

With front-to-back or back-to-front airflow

•

With AC or DC power supplies

NOTE: In rare cases, EX3300 switches running a Junos OS release prior to

Release 11.3R4 or Release 11.4R2 might experience some traffic loss or a link failure as a result of non-user-configurable settings that are not optimized. To resolve this issue, upgrade to one of the following Junos OS releases:

•

Junos OS Release 11.3—R4 and later

•

Junos OS Release 11.4—R2 and later

•

Junos OS Release 12.1—R1 and later
