Product description
Cost-effective full PoE+ power solution ideal for hardened
environment
Featuring Plug and Play designed to be installed in heavy
industrial demanding environments, the industrial PoE+
switches are industrial-grade, DIN-rail type unmanaged Fast
Ethernet PoE+ switches with four 10/100BASE-TX PoE+ ports,
with one additional Fast Ethernet (NS2052-4P-1T) or
100BASE-FX fiber optic (MC252-4P-1S) interface for video
uplink. The industrial PoE+ switches are designed with a
redundant power system and operate reliably, stably, and
quietly in any hardened environment without affecting
performance. It comes with a total power budget of up to 120
W for different kinds of PoE applications and an operating
temperature ranging from -40 to 75°C in a rugged IP40 metal
housing.
Extension of ethernet data transmission distance
The industrial PoE+ switch has a built-in solid DIP switch
providing Standard, VLAN, and Extend operation modes. By
default, the industrial PoE+ switch operates as a normal IEEE
802.3af/at PoE+ switch in the “Standard” operation mode.
The "VLAN" operation mode features with port-based VLAN
function helps to prevent the IP camera’s multicast or
broadcast storm from influencing each other.
In the “Extend” operation mode, the industrial PoE+ switch
operates on a per-port basis at 10 Mbps full duplex operation
and can support 25 W PoE power output over a distance of up
to 250 meters, overcoming the 100-meter limit on Ethernet
UTP cable.
Convenient and reliable power system
To facilitate the 802.3at PoE+ usage with commonly used
12~48V DC power input for transportation and industrial-lev el
applications, the industrial PoE+ switch adopts 12~48 VDC to
54V power boost technology to solve power source issues but
does not require special power supplies. The industrial PoE+
switch provides an integrated power solution with a wide range
of voltages (12~48 VDC) for worldwide operability. It also
provides dual-redundant, reversible polarity 12~48 VDC power
supply inputs for high availability applications.
Environmentally hardened design
With the IP40 metal industrial case, the industrial PoE+ switch
provides a high level of immunity against electromagnetic
interference and heavy electrical surges which are usually
found on plant floors or in curb-side traffic control cabinets
without air conditioning. It features a ventilated construction in
which a cooling fan is not necessary, thereby making its
operation noiseless. Being able to operate under the
temperature range from -40 to 75°C, the industrial PoE+ switch
can be placed in almost any difficult environment.
Robust protection
The industrial PoE+ switch provides contact discharge of ±5
KV DC and air discharge of ±5 KV DC for Ethernet ESD
protection. It also supports ±5 KV surge immunity to improve
product stability and protects users’ networks from devastating
ESD attacks, making sure the flow of operation does not
fluctuate.

DIP switch
The industrial PoE+ switch provides one DIP switch for
Standard, VLAN, and Extended mode selections. The detailed
descriptions are shown in the following table.
Function
Standard
In this mode, the industrial PoE+ switch operates
as a general switch and all PoE ports operate at
10/100Mbps auto-negotiation.
VLAN
In this mode, the industrial PoE+ switch operates
as a VLAN isolation switch and
1. Port 1 to port 4 will isolate respectively.
2. Port 1 to port 4 can only communicate with
port 5.
Note: After adjusting the VLAN DIP switch,
reboot the industrial PoE+ switch to effectuate
change.
Extended
In this mode, the industrial PoE+ switch operates
on a per-port basis at 10 Mbps full duplex
operation but can support IEEE 802.3af PoE
power output over a distance of up to 250 meters
overcoming the 100 m limit on a Ethernet UTP
cable.
