The Switch system’s housing is designed with one pieces of heat-sink to dissipate heat when perform high power PoE for DOME IP Camera, Wireless AP. It also provides excellent heat dissipation, even working in road-side cabinet, it still can deliver high power to far-end PoE-PDs. It also adopts comprehensive Layer-3 IP routing feature with brilliant Electro-Magnetic
Susceptibility testing level carried out the ability for the Railway Track –Side surveillance.

High Performance DataAcquisition       
The Ethernet Switch designed with high Switching
Fabric for field data acquisition, and exchange with
data center. With the highest Switch Fabric and data
stream buffer, the JetNet 7310G approached seamless
connective between data center and filed IP
surveillance applications. It also provides 9Kbytes
packet forwarding ability and excellent H.264 burst
stream management technology achieved stable video
security through IP surveillance.

Flexible Uplink Media for Network
Architecture Extension
In the metro network architecture, the optical fiber is
commonly to use for uplink connection. The JetNet
7310G offers 2 SFP ports with smart fiber transceiver
recognize technology approached high quality optical
fiber connectivity and enlarge network topology. The
Plug and Play characteristics makes user easily change
the SFP transceiver for longer communication distance
or higher speed connection without any preconfiguration .

Fiber Optical Quality Monitoring
The fiber optical transmission quality may become
unstable, due the moisture, dust or laser diode senile.
To reduce the threat of signal broken, the Ethernet
Switch provides Digital Diagnostic Monitoring (DDM) to
recognize the specification of fiber transceiver. The
DDM function enabled user to monitor the launched
power, received signal strength, temperature and also
alerts user if fiber signal quality getting poor.

Cyber Network Redundancy
In the Industrial network communication, the
reliability of communication always is the critical
issue. The 7310G adapts new network redundancy
technology – Cyber Network Redundancy includes MSR,
Super Chain, ERPS and IEEE standards- RSTP/MSTP
technologies to ensure network reliability.
The MSR is a seamless network redundant technology,
which includes various technologies for different
network redundancy topologies and applications. It
includes Rapid Super Ring (RSRTM), Rapid Dual
Homing(RDHTM), MultiRingTM and TrunkRingTM. With
those network redundant technologies, a node can be
configured to multiple rings with failover time less
than 50ms, and zero of restoration time.Read more

Advanced Cyber Security
The JetNet Switch supports several advanced
network security functions to ensure the IT system
and data will not get any threat from Cyber
network (Internet). The advanced security function
includes DHCP Snooping protection, Dynamic ARP
inspection (DAI), IP source guard (IPSG), Distribute
Denial-of-Service protectionand IEEE 802.1x MAB.

DHCP Snooping Protection
The DHCP Snooping is a series of techniques applied
to the security of an existing DHCP network . With
the DHCP Snooping, the DHCP Server will manage
the network access and permit the access with
specific IP and specific MAC address from specific
Switch port can access the network. It also provides
the protection to avoid the intruder added fake
DHCP server into a secured network and try to take
over DHCP process. Once the Switch detects the
phenomena, the port of intruder connected will be
lock to protect network access.

Dynamic ARP inspection Protection
The Dynamic ARP Inspection (DAI) is a security
feature that prevents ARP attack. The Switch
receives one ARP packet on an untrusted port, the
switch compares the IP-to-MAC address binding with
entries from the DHCP Snooping database or ARP
access-lists. If there is no match, the ARP packet
will be dropped by the Switch to ensure network
performance.

IP Source Guard (IPSG)
IP Source Guard is a security feature that restricts IP
traffic on untrusted Switch port by filtering traffic
based on the DHCP snooping binding database or
manually configured IP source bindings. This feature
helps prevent IP spoofing attacks when a host tries
to spoof and use the IP address of another host.

Denial of Service (DoS) Prevention
In the internet, a Denial of Service (DoS)
or Distributed Denial-of-service (DDoS) attack is an
attempt to make a computer or network resource
unavailable for intended operating. For the managed
Ethernet Switch, the attacker may send lot of
service inquire packets to the Switch, and it may
caused Switch’s CPU get slowly and the network may
malfunction. With the DoS protection, the Switch
will far way the treat of zombie computer, and keep
the network operating as well.

Layer-3 Routing – Accelerates Data
Stream in Complex-Network
The Routing is the process of moving packets between
different IP address domain or forward to internet. To
forward traffic, a router or a Layer-3 Switch need to
known the Destination/ Source IP address, the possible
and best routes, and verifying /maintain the routing
information. The JetNet 7310G offers various of Layer3 features- Static/ Dynamic routing, VLAN routing, IP
Multicasting routing, VRRP and OSPF routing. With
those routing function, the Switch can route IP stream
in quick and efficiency with high speed scalability, low
latency, flow accountable and security as well as.

Advanced Layer 2 plus Access Security
In some of industrial automation fields, the advanced
network security features are required and must be
implemented into field devices. The secured Access
Control List (ACL) makes it easy to limit certain
communication with other addressed devices by the
specific protocol. The ACLs provide “Permit” and
”Deny” rules for any or specific host. The
Source/Destination MAC address, global IP address or
extend IP address with protocol type could be applied
as the rules to secure the network from field site
access.

Remote Power Feeding (Power over Ethernet)
The Power over Ethernet technology of JetNet
7310G is compliance
standards with 1-event
for PD classification.
with IEEE 802.3at/af
and 2-event behaviors
The System maximum
power forwarding up to 240W at 75°C operating
environment, each PoE port power capability up
to 35W. With the high power PoE solution,
JetNet Switch can fulfill the demand of High
Power Wireless AP, Dom IP Camera with thermal
heater.

Smart Powered Device AliveCheck
The far-end PoE/PD system status can be monitor
by enabled the PoE “Link Partner Line Detection”
function. Once the PD fails, the connected PoE
Switch port will reset the PoE output and bring the
PD back to normal working state. This greatly
enhance the reliability that PoE/PSE Switch will
reset the far-end Powered Device (PD) and reduces
your management burden

PoE Scheduling Control
The JetNet 7310G provides an scheduling PoE power
control mechanism based on hourly/weekly. The
PoE port can be configured with different on-off
time-slot behaviors by Web user interface, just
click and choice PoE-On time-slot and weekly day,
then apply the setting to activate it. With the PoE
Scheduling Control feature, the JetNet 7310G can
meets economical power management, power
saving, security or customer-specific requirements.

Survival in Hash Environment
The technology of PoE are commonly deployed in
smart city applications, like as public facility IP
surveillance, free Internet Therefore, the Switch may
