Virtual Chassis Technology
The EX3300 supports Juniper Networks Virtual Chassis technology,
allowing up to 10 switches to be interconnected over uplink ports
and be managed as a single logical device, delivering a scalable,
pay-as-you-grow solution for expanding network environments.

when deployed in a Virtual Chassis configuration, the EX3300
switches elect a master and backup switch based on a set of
criteria or preconfigured policies. The master switch automatically
creates and updates the switching and optional routing tables on
all switches in the Virtual Chassis configuration. Virtual Chassis
technology allows switches to be added or removed without
service disruption. An EX3300 Virtual Chassis configuration
operates as a highly resilient unified system, providing simplified
management using a single IP address, single telnet session,
single command-line interface (CLI), automatic version checking,
and automatic configuration. The EX3300 switches are also
capable of local switching, so that packets coming into a port
destined for another port on the same switch do not have to
traverse the Virtual Chassis, increasing the forwarding capacity of
the switch.

The EX3300 implements the same slot/module/port numbering
schema as other Juniper Networks chassis-based products when
numbering Virtual Chassis ports, providing true chassis-like
operations. By using a consistent operating system and a single
configuration file, all switches in a Virtual Chassis configuration
are treated as a single device, simplifying overall system
maintenance and management.

These two ports can also be configured as GbE or 10GbE uplinks
to aggregation devices by disabling Virtual Chassis technology.

Converged LAN Environments
The EX3300 switches provide a flexible solution for demanding
converged data, voice, and video environments. The EX3300-24P
and EX3300-48P support the IEEE 802.3at Power over Ethernet
(PoE) standard, also known as PoE+, delivering up to 30 watts of
power per port to support networked devices such as telephones,
video cameras, IEEE 802.11n wireless LAN (wLAN) access points,
and video phones. The PoE+ standard provides nearly double the
15.4 watts per port available with the IEEE 802.3af PoE standard.

The EX3300-48P includes a total PoE power budget of 740 watts,
enabling the switch to provide the full 15.4 watts of 802.3af Class
3 PoE to all 48 ports, or the full 30 watts of PoE+ to 24 ports. The
switch can support any combination of PoE and PoE+ ports until
the maximum PoE power budget of 740 watts is exhausted.
