FCC Warning
This Equipment has been tested and found to comply with the limits for a Class-A digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy. It may cause harmful
interference to radio communications if the equipment is not installed and used in
accordance with the instructions. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
CE Mark Warning
This is a Class-Aproduct. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.

1.1. Product Brief Description
Introduction
The switch is 16-port 10 Base-T / 100 Base-TX / 1000 Base-T + 2 Gigabit SFP L2+
Management PoE Switch that is designed for small or medium network environment to
strengthen its network connection. The 16 10 Base-T / 100 Base-TX / 1000 Base-T ports
support IEEE 802.3at PoE technology, up to 30W per port and maximum 100m transmission
distance. The switch equipped with AC to DC power module to support 235W power budget
for PoE power. The switch also supports Layer 2+ full management software features. These
features are powerful to provide PoE Control, Network Control, Management, Monitor and
Security features’ requests. It is a superb choice to boost your network with better
performance, efficiency and high PoE power consumption.
IEEE 802.3at Power over Ethernet (PoE) ports
The switch features 16 IEEE 802.3at Power over Ethernet (PoE) ports supplying up to 30
watts per port. This product can convert standard 100~240V/AC power into low-voltage DC
that runs over existing LAN cable to power up IEEE 802.3at compliant network accessories.
It also features PoE awareness to verify whether the network device receive power is IEEE
802.3at compliant, or only the data will be sent through LAN cable. By adding the switch to
the existing networking, installing networking products such asAccess Points and IP
cameras can be easily managed and set up. Wireless device deployments are easily located
with available power outlets and network administrators don’t need to use heavy AC power
adapters anymore.
2 Gigabit SFP Open Slots
The switch supports 2 additional SFP open slots to uplink to servers, storage, or other
switching devices for long loop reach applications. The 2 SFP slots can support different
types, speed and distance SFP transceivers. It also supports legacy 100M SFP transceiver.
If the 100M fiber infrastructure is constructed and 100M bandwidth is enough, the 100M SFP
transceiver can be an optional choice for the legacy 100M network environment.
Full Layer 2 Management Features
The switch includes full Layer 2+ Management features. The software set includes up to 4K
802.1Q VLAN and advanced Protocol VLAN, Private VLAN, MVR…features. There are 8
physical queues Quality of Service, IPv4/v6 Multicast filtering, Rapid Spanning Tree protocol
to avoid network loop, Multiple Spanning Tree Protocol to integrate VLAN and Spanning
Tree, LACP, LLDP; sFlow, port mirroring, cable diagnostic and advanced Network Security
features. It also provides Console CLI for out of band management and SNMP, Web GUI for
in band Management.

1.3. Hardware Description
This section mainly describes the hardware of Full-Management PoE switch and gives a
physical and functional overview on the certain switch.
Front Panel
The front panel of the Full-Management PoE switch consists of 16 10 Base-T / 100 Base-TX
/ 1000 Base-T RJ-45 ports and 2 gigabit uplink SFP ports. The LED Indicators are also
located on the front panel.
LED Indicators
The LED Indicators present real-time information of systematic operation status. The
following table provides description of LED status and their meaning.

*If a new PD is connected to the PoE switch and the PoE budget is depleted, the PoE LED will
start blinking. No Power will be provided and the user must allocate PoE power manually.
Rear Panel
The rear panel of the Full-Management PoE switch contains a power switch, and an IEC
60320 plug for power supply.

Hardware Installation
User Manual. NGSME16T2H 19
1.4. Hardware Installation
To install the Full-Management PoE switch, please place it on a large flat surface with a
power socket close by. This surface should be clean, smooth, and level. Also, please make
sure that there is enough space around the Full-Management PoE switch for RJ45 cable,
power cord and ventilation.
If you’re installing this Full-Management PoE switch on a 19-inch rack, please make sure to
use the rack-mount kit (L brackets) and screws come with the product package. All screws
must be fastened so the rack-mount kit and your product are tightly conjoined before installing
it on your 19-inch rack.
Ethernet cable Request
The wiring cable types are as below:
10 Base-T: 2-pair UTP/STP CAT. 3, 4, 5 cable, EIA/TIA-568 100-ohm (Max. 100m)
100 Base-TX: 2-pair UTP/STP CAT. 5 cable, EIA/TIA-568 100-ohm (Max. 100m)
1000 Base-T: 4-pair UTP/STP CAT. 5 cable, EIA/TIA-568 100-ohm (Max. 100m)
PoE: To delivery power properly, it is recommended to use CAT 5e and CAT 6 cable.
Ethernet cables of higher qualities can reduce the power lost during transmission.
SFP Installation
While install the SFP transceiver, make sure the SFP type of the 2 ends is the same and the
transmission distance, wavelength, fiber cable can meet your request. It is suggested to
purchase the SFP transceiver with the switch provider to avoid any incompatible issue.
The way to connect the SFP transceiver is to Plug in SFP fiber transceiver fist. The SFP
transceiver has 2 plug for fiber cable, one is TX (transmit), the other is RX (receive). Cross-
connect the transmit channel at each end to the receive channel at the opposite end.

Preparing for Management
In Preparing for Management:
This section will guide your how to manage this product via serial console,
management web page, and Telnet/SSH interface.
The switch provides both out-of-band and in-band managements.
Out-of-band Management: You can configure the switch via RS232 console
cable without having the switch or your PC connecting to a network. Out-of-band
management provides a dedicated and secure way for switch management.
In-Band Management: In-band management allows you to manage your switch
with a web browser (such as Microsoft IE, Mozilla Firefox, or Google Chrome) as
long as your PC and the switch are connected to the same network.
