Product Introduction
This Switch is a 10G Full Managed PoE Switch. It provides 8 x10/100/1000Mbps Auto-Negotiation RJ45 PoE ports and 4 x10Gbps SFP ports, which can satisfy the full speed forwarding of ports. The Switch uses 19” 1U standard chassis rack or can be used on the desktop.
Front Panel
The front panel consists of LED indicators and network ports.
LED Lamp
Power LED: The Power LED lights up when the Switch is connected to a power source.
Link/Act indicator: The light indicates the network connection through the corresponding port. Flicker indicates that the switch is sending or receiving data.
PoE indicator: Blinking indicates that the PD device is connected to the corresponding port, and Off indicates that the port is not powered or no PD device is found.
Rear Panel
The rear panel view of the Switch consists of an AC power connector.
Plug the female connector into the Switch and male connector into a power outlet. Supports input voltages 100-240VAC, 50/60Hz.
Switch: Turn on the switch after inserting the power cord, “I” means to turn on, “O” means off.
Grounding: Use specialized ground lead connect.
HARDWARE INSTALLATION
This chapter provides unpacking and installation information for the Switch.
Open a Seal
Open the shipping carton and carefully unpack its contents. Please consult the packing list located in the User Manual to make sure all items are present and undamaged. If any item is missing or damaged, please contact us for replacement.
- Switch 1 pcs
- AC power cord 1 pcs
- Rubber feet 4 pcs
- Screws 6 pcs
- Mounting brackets 2 pcs
- User’s manual 1 pcs
- Serial port lines 1 pcs
Switch Installation
For safe switch installation and operation, it is recommended that you:
- Visually inspect the power cord to see that it is secured fully to the AC power connector.
- Make sure that there is proper heat dissipation and adequate ventilation around the switch.
- Do not place heavy objects on the switch.
Desktop Installation
When installing the switch on a desktop, the rubber feet included with the device must be attached on the bottom at each corner of the device’s base. Allow enough ventilation space between the device and the objects around it.
Rack Installation
The switch can be mounted on a EIA standard size 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets to the switch’s side panels (one on each side) and secure them with the screws provided.
Then, use the screws provided with the equipment rack to mount the switch in the rack.
Plugging in the AC Power Cord
You can connect AC power supply cord to switch back and the other side to a power outlet (power outlet must be well grounded and support over voltage protection).
Warning: Do not turn on the power switch before power cables are connected. Power surge may cause damage to the Switch.
Using Web-based Management
After a successful physical installation, you can configure the Switch, monitor the network status, and display statistics using a web browser.
Supported Web Browsers
The embedded Web-based Management currently supports the following web browsers:
- Internet Explorer 6 or higher version
- Chrome
- Mozilla
- Firefox 1.5/2.0 or higher version
You will need the following equipment to begin the web configuration of your device:
- PC with a RJ-45 Ethernet connection
- Standard Ethernet network cable
With a standard Ethernet cable, connect the Ethernet cable to any of the ports on the front panel of the switch and to the Ethernet port on the PC.
Login Web-based Management
- To access the GUI of the switch, open a browser and type the default management address http://192.168.0.1 in the address field of the browser, then press the Enter key.
Note:
- To log in to the switch, the IP address of your PC should be set in the same subnet as that of the switch. The IP address is 192.168.0.x (”x” is any number from 2 to 254). Subnet Mask is 255.255.255.0.

- Enter admin for both the User Name and Password in lower case letters. Then click the Login button or press the Enter key.

- After a successful login, the main page will appear as follows, and you can click the menu on the left side to configure the corresponding functions.

Note: For more details about how to configure the switch, see the User Guide on www.poewit.com.
