1.1. Product Brief Description
Introduction
This NGSME24G4S switch is 24-port 10/100/1000Base-T and two 10G SFP+for Stacking
and two 10G SFP+ Open Slot Rack-mount L2+Full Management Network Switch that is
designed for medium or large network environment to strengthen its network connection. This
NGSME24G4S switch supports 128Gbps non-blocking switch fabric, its 24 gigabit ports and 2
10G uplink ports can transmit and receive data traffic without any lost. The EEE feature
reduces the power consumption when there is no traffic forwarding even port is still
connected. The 10G uplink port design is available and important for high bandwidth uplink
request when cascaded with other switch. This NGSME24G4Sswitch also supports Layer 2+
full management software features. These features are powerful to provide network control,
management, monitor and security feature requests. Including rack-mount brackets, the 19"
size fits into your rack environment. It is a superb choice to boost your network with better
performance and efficiency.
Two 10 Gigabit SFP+ Open Slots
This NGSME24G4S switch equips with two 10G SFP+open slots as the uplink ports, the 10G
uplink design provides an excellent solution for expanding your network from 1G to 10G. By
10G speed, this product provides high flexibility and high bandwidth connectivity to another
10G switch or the Servers, Workstations and other attached devices which support 10G
interface. The user can also aggregate the 10G ports as Trunk group to enlarge the
bandwidth.
Stacking Features
The NGSME24G4S switch include a stacking feature by using 2 SFP+ports that allows
multiple switches to operate as a single unit.A single switch in the stack can manages all the
units in the stack and uses a single IP address which allows the user to manage every port in
the stack from this one address. These stacks can include up to 16 switches, or total 384
gigabit ports plus 32 10G ports in total.
Full Layer 2 Management Features
The NGSME24G4S 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 queriers 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.

Hardware Installation
NGSME24G4S User Manual | 19
1.4. Hardware Installation
To install the NGSME24G4 Sswitch, 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 NGSME24G4S switch for RJ45 cable, power cord and
ventilation.
If you’re installing this NGSME24G4S 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.
