PoeWit NS8-4B User manual

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.
3) 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 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.

This guide provides instructions to install the NS8-4B switch.
NOTE: The model you have purchased may appear slightly
different from the illustrations shown in the document. Refer to
the Product Instruction and Technical Specification sections for
detailed information about your switch, its components, network
connections, and technical specifications.
This guide is divided into four parts:
1. About guide: Terminology/Usage
2. Product introduction: Product overview and panel definitions
3. Hardware installation: Step by step hardware installation process
4. Technical specifications
Terminology / Usage
In this guide, the term “Switch” (first letter capitalized) refers to
this PoE Switch, and “switch” (first letter lower case) refers to
other PoE switches. Some technologies refer to terms “switch”,
“bridge” and “switching hubs” interchangeably, and both are
commonly accepted for Ethernet switches.
Note: Indicates important information that helps a better use of
the device.
Warning: Indicates potential property damage or personal injury.

2) PRODUCT INTRODUCTION
This Switch is a Smart Managed PoE Switch. It provides
8x10/100/1000Mbps Auto-Negotiation RJ45 ports, 4 of the ports
are 802.3bt PoE. In addition, 2x10/100/1000Mbps SFP, 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.

1. PC with a RJ-45 Ethernet connection
2. 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
1. To access the GUI of the switch, open a browser and type the IP
address of the switch. NOTE- the default is DHCP (if DHCP
Server is present), or 192.168.1.1.
Note:
1) 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 192.168.1.x (”x” is any
number from 2 to 254). Subnet Mask is
255.255.255.0.
2) Enter admin for both the User Name
and Password in lower case letters.
Then click the Login button or press
the Enter key.
3) After a successful login, the main page will appear as follows,

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