3. Installation
3.1 Hardware and Cable Installation
CAUTION: Wear a grounding device to avoid damage from electrostatic discharge.
Be sure that the power switch is OFF before you connect the power cord to the power source.
3.1.1 TP Port and Cable Installation
1. The switch’s TP ports support Auto-MDI/MDI-X crossover, so you can use straight-through (Cable pin-outs for RJ-45
jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP and 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-
over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2). You don’t have to figure out if the cable is pinned straight-
through or crossover, just plug it in.
2. Connect one end of a CAT5 grade RJ-45 twisted-pair (TP) cable or above to a twisted-pair port on the switch. Connect
the other end to a network device, such as a workstation or a server.
3. Repeat the above steps, as needed, for each RJ-45 port to be connected to a 10/100/Gigabit TP device.
The switch is now ready to operate.
3.1.2 Installing Optional SFP Transceiver Module
NOTE: If you do not plan to install SFP fiber transceivers in the switch’s ports F1–F4, skip this section.
Slide the fiber transceiver module into one of the two open module slots in the switch as shown in Figure 3-1.
Connecting the SFP Module to the Chassis
The optional SFP modules are hot-swappable, so you can plug or unplug them before or after powering on the switch.
1. Verify that the SFP module is the right model and conforms to the chassis.
2.
3. Slide the module into the slot. Make sure that the module is properly seated against the slot socket/connector.
4.
5. Connect the fiber optic network cable to the connector(s) on the module.
6.
7. If you want to install a second module in the switch, repeat steps 1–3.

SFP transceiver
module
Figure 3-1.
3.1.3 Power On
The switch supports a 100–240 VAC, 50–60 Hz power supply. The power supply will automatically convert the local AC
power source to DC power. It does not matter whether or not any connection is plugged into the switch when powering on.
After the power is on, all LED indicators will light up and then all will turn off, except for the power LED, which stays on.
3.2 Installing Switch to a 19-Inch Wiring Closet Rail
CAUTION: Allow proper spacing and air ventilation for the cooling fan at both sides of the switch.
Wear a grounding device for electrostatic discharge.
1. Using two screws (included), attach the rackmount ears to the switch’s left and right sides. See Figure 3-2.
2. Line up the mounting holes on the switch assembly (the switch with rackmount ears installed) with the mounting holes
on a 19" wiring closet rack. Install two screws (included) to hold the switch in place in the rack.

16/24 Port Gigabit PoE PSE With 4 SFP Slots Web Smart Switch
Figure 3-2 Install the switch chassis in a 19"rack
3.3 Cabling Requirement
For successful installation and good network performance, use CAT5, CAT5e, or higher cable. If you use non-compliant
cables, the LAN will work poorly.
For a Fast Ethernet TP network connection, the grade of the cable must be CAT5 or CAT5e with a maximum length of
328 feet (100 meters).
3.4 Switch Cascading in Topology
Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may uplink an
unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with
the IEEE 802.3/802.3u and other 802.1 series protocol specifications, which limit the timing requirement from physical
signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and timer from some OSI layer 2
protocols such as 802.1d, 802.1q, and LACP.
The TP cables, and devices’ bit-time (round-trip) delay are as described in Table 3-1.
100Base-TX TP
Round trip Delay: 512
1.12/m
Cat. 5 TP Wire:
TP to fiber Converter: 56
Bit Time unit: 0.01 s (1sec./100 Mega bit)
Table 3-1. Cable’s bit-time (round-trip) delay.
Page 12
Download from Www.Somanuals.com. All Manuals Search And Download.
16/24 Port Gigabit PoE PSE With 4 SFP Slots Web Smart Switch
The sum of all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within the required Round
Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this does not apply.
3.5 Set IP Address, Subnet Mask, and Default Gateway IP Address
First, configure your PC IP address or change the IP address of the switch. Next, change the default gateway’s IP
address and subnet mask.
For example, suppose your network address is 10.1.1.0, and subnet mask is 255.255.255.0. You can change the switch’s
default IP address 192.168.2.1 to 10.1.1.1 and set the subnet mask to be 255.255.255.0. Then, choose your default
gateway, for example, 10.1.1.254.
Default Value
IP Address
LPBG716A/LPBG724A Your Network Setting
192.168.2.1
10.1.1.1
Subnet
255.255.255.0
192.168.2.254
255.255.255.0
10.1.1.254
Default Gateway
After completing these settings in the switch, it will reboot and the configuration will take effect. After this step, you can
operate the management through the network.
NOTE: There are no default DNS settings. DNS addresses are assigned by the network administrator.
Before you communicate with the switch, first finish the IP address configuration or make sure you know the switch’s IP
address. Then, follow the procedures listed below.
1. Set up a physical path between the configured the switch and a PC using a qualified UTP CAT 5 cable with RJ-45
connector.
NOTE: If a PC directly connects to the switch, you have to setup the same subnet mask between them. The subnet mask
may be different for the PC in the remote site. See the screen shown below for the switch’s default IP address information.
Figure 3-4. Type address in URL column.
Default IP address: 192.168.2.1
Default Password: admin

4. Web-based Management Operation
This chapter instructs you how to configure and manage the switch through the Web user interface it supports. You can
access and monitor the switch’s status, including port activity, spanning tree status, port aggregation status, VLAN, and
priority status and so on from any one port on the switch.
The default values of the managed switch are listed in the table below:
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.254
Password: admin
Type http://192.168.2.1 in the address row in a browser. It will show the following screen (Figure 4-1) and ask you to input
the ID and password to login and access authentication. The default ID and password are both “admin.” The first time you
login, please enter the default ID and password, then click the <OK> button. The login process now is completed.
