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-B product. 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 48-port 10 Base-T /100 Base-TX /1000Base-T + 4 x 10 Gigabit SFP+ Ports
Rack-mount L2+ Full Management Network Switch that is designed for medium or large
network environment to strengthen its network connection. The switch supports 176G
non-blocking switch fabric, the 48 gigabit ports and 4 uplink 10G 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 switch 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.
Four 10 Gigabit SFP+ Open Slots
The switch equips with 4x 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 interfaces. The user
can also aggregate the 10G ports as Trunk group to enlarge the bandwidth.
IEEE 802.3at/af Power over Ethernet (PoE) ports
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/af compliant network accessories. It also
features PoE awareness to verify whether the network device receive power is IEEE
802.3at/af 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.
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…advanced VLAN 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.

Advanced Security
The switch supports advanced security features. For switch management, there are secured
HTTPS and SSH, the login password, configuration packets are secured. The port binding
allows to bind specific MAC address to the port, only the MAC has the privilege to access the
network. The 802.1X port basedAccess Control, every user should be authorized first when
they want to access the network. AAA is the short of the Authentication,Authorization and
Accounting with RADIUS, TACAS+ server. Layer 2+ Access Control List allows user to define
the access privilege based on IP, MAC, Port number…etc.
PD Alive Check
When this function is enabled, this switch will detect a network PoE powered device (for
example, an IP CAM) with a set of IP address periodically. If the switch doesn’t get any replies
from the network PoE powered device, this switch will do a power cycle (PoE power OFF, and
PoE power ON) to the port that connects the network PoE powered device, allowing that
device to reboot. You can set the frequency of detecting, number of times of detecting, and
the time period to perform power cycle when there’s no reply via the switch’s PoE
configuration web page.

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 switch consists of 48 10/100/1000 Base-TX RJ-45 ports and 4 10
Gigabit SFP+ ports. The LEDs are also located on the front panel.
LED Indicators
The LED Indicators present real-time information of systematic operation status. Each of the
switch’s RJ45 port has two LEDs, the green LED indicates RJ45 connection status/data link,
and the amber LED indicates if that port is providing electrical power.
Also, port 49 to port 52 (SFP+ Ports) has their own LEDs that indicate data link.

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.

2.1. Preparation for Web Interface
The management web page allows you to use a web browser (such as Microsoft IE, Google
Chrome, or Mozilla Firefox) to configure and monitor the switch from anywhere on the
network.
Before using the web interface to manage your switch, please verify that your switch and your
PC are on the same network. Please follow the steps down below to configure your PC
properly:
1. Verify that the network interface card (NIC) of your PC is operational and properly
installed, and that your operating system supports TCP/IP protocol.
2. Connect your PC with the switch via an RJ45 cable.
3. The default IP address of the switch is 192.168.2.1. The switch and your PC should
locate within the same IP Subnet. Change your PC's IP address to 192.168.2.X, where
X can be any number from 2 to 254. Please make sure that the IP address you’ve
assigned to your PC cannot be the same with the switch.
4. Launch the web browser (IE, Firefox, or Chrome) on your PC.
5. Type 192.168.2.1 (or the IP address of the switch) in the web browser’s URL field, and
press Enter.
