Part number: EX3400-48P
Brand: Juniper
Description: EX3400 48-port 10/100/1000BaseT PoE+, 4 x 1/10G SFP/SFP+, 2 x 40G QSFP+, redundant fans, front-to-back
airflow, 1 AC PSU JPSU-920-AC-AFO included (optics sold separately)
Condition: New and factory sealed
Availability: Stock in Las Vegas ready to ship!
48-port model with and without Power over Ethernet (PoE/PoE+)
Cloud-ready and zero-touch provisioning (ZTP) -enabled for Juniper
Data center-optimized cooling options offer both front-to-back and back-to-front
airflows, making the EX3400 suitable for GbE data center access deployments.
Two redundant, field-replaceable power supplies each provide up to 920 watts of
power.
Four dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+)
uplink ports and two 40GbE QSFP+ ports are available.
Uplink ports can be configured as Virtual Chassis interfaces and connected via
standard 10GbE/40GbE optic interfaces (40GbE uplink ports are preconfigured by
default as Virtual Chassis ports).
Comprehensive Layer 2 functionality with RIP and static routing is provided.
A compact, 13.8 -inch deep 1 U form factor supports flexible deployment options.
Power
The EX3400 supports the 802.3 af Class 3 Power over Ethernet
(PoE) and 802.3 at PoE+ standards for supporting networked
devices such as telephones, video cameras, IEEE 802.11 ac WLAN
access points, and videophones in converged networks. While
EX3400 switches ship with a single power supply by default, they
can support redundant 600W or 920W power supplies that
provide PoE ( 15.4W ) or PoE+ (30W) power to all ports in the
switch. Spare power supplies can be ordered as needed.
There are two PoE power mode settings on the
EX3400 switches:
Static mode allows customers to specify the maximum PoE
power setting on an individual port.
Class mode allows end devices to specify PoE class and
negotiate whether the switch can provide PoE power to the
device.
The EX3400 also supports the industry-standard Link Layer
Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery
(LLDP-MED), which enable the switches to automatically discover
Ethernet-enabled devices, determine their power requirements, and
assign virtual LAN (VLAN) parameters. LLDP-MED-based granular
PoE management allows the EX3400 to negotiate PoE usage down
to a fraction of a watt on powered devices, enabling more efficient
PoE utilization across the switch.
The EX3400 supports the IEEE 802.3 az standard for Energy
Efficient Ethernet (EEE) functionality, reducing power consumption
of copper physical layers during periods of low link utilization.
In addition, the EX3400 supports rich quality-of-service (QoS)
functionality for prioritizing data, voice, and video traffic. The
switches support 12 QoS queues (8 unicast and 4 multicast) on
every port, enabling them to maintain multilevel, end-to-end traffic
prioritization. The EX3400 also supports a wide range of scheduling
options, such as priority and shaped-deficit weighted round-robin
(SDWRR) scheduling.
