16-Port Switch
2.3.1 Port Speeds
10/100Mbps TP ports
Each 10/100MbpsTP port provides anAuto-Negotiation function and an Auto-Crossover (Auto-MDI/MDIX) function that senses
for the attached device's maximum operating speed and automatically sets the Switch to operate at that speed. Each TP port
uses RJ-45 connector that allows network TP cables to be easily attached or removed. Users only need to connect a network
device into any TP port and the Switch will do the rest.
2.3.2 Cabling
10Mbps – Category 3, 4, or 5 TP cabling can be used for transmitting data at 10Mbps or 20Mbps bandwidth on 10BASE-T
networks.
100Mbps – Only Category 5 TP cabling can be used for transmitting data at 100Mbps or 200Mbps bandwidth on 100BASE-TX
networks.
Port Type CableType Connector
10BASE-T Category 3, 4 or 5 TP RJ-45
100BASE-TX Category 5 TP RJ-45
Note: Category 5 TP cable should be used whenever installing newTP cabling.

2.4.2 DIP-Switch
This Switch provides DIP-Switches setting to configuration, the configuration setting as below:
a. Home VLAN
We have provided two DIP-Switches for the Home VLAN setting.
Left side DIP-Switch Right side DIP-Switch
SW up Home VLAN Disable Home VLAN TYPE A
SW down Home VLAN Enable Home VLAN TYPE B
Home VLAN TYPE A: Select 14 VLANs (port#1 Ƒ #7, #9 Ƒ #15) with two overlapping ports (port#8, #16) topology. (VLAN1:
port#1, #8, #16; VLAN2: port#2, #8, #16; VLAN3: port#3, #8, #16, …; VLAN14: port#15, #8, #16)
Home VLAN TYPE B: Select 15 VLANs(port#1
Ƒ #15) with one overlapping port (port#16) topology. (VLAN1: port#1, #16; VLAN2:
port#2, #16; …; VLAN15: port#15, #16)
This function for network topology security configuration. When the Port-Based security function is enabled, the 16-Ports Switch
can be configured as 14 (or 15) individual VLANs that share the same two (or one) overlapping port(s). This 14 VLANs or 15
VLANs topology is useful to allow home networks to share common servers or routers, this function can be used on Fiber To The
Home (FTTH) or Ethernet To The Home (ETTH) application.
Note: Only when the left sideDIP-Switch move to “ON”, the function of the right side DIP-Switch would be active.
b. TRUNK
We have support Four DIP-Switches for the TRUNK Port setting.
ABCD
SW up TRUNKADisable TRUNK B Disable TRUNK C Disable TRUNK D Disable
SW down TRUNKAEnable TRUNK B Enable TRUNK C Enable TRUNK D Enable
ƍ TRUNKA: Port#1, #2, #9, #10
ƍ TRUNK B: Port#3, #4, #11, #12
ƍ TRUNK C: Port#5, #6, #13, #14
ƍ TRUNK D: Port#7, #8, #15, #16
If the trunk function enable, it can be provided 800Mbps bandwidth between two devices, it is useful to allowhigh bandwidth in
Backbone or server connection.
Note: If the Home VLAN function is enabled, it will disable the TRUNK function setting.
c. 100FX (100BASE-FX operation mode setting) (only for Switch w/ Fiber port)
This DIP-Switch is setting to configuration 100Mbps Half-/Full-Duplex on the Fiber port.
Operation mode
SW up 100Mbps Half-Duplex
SW down 100Mbps Full-Duplex
Note: When the DIP-Switches configuration changes, the Switch had to be “Power Reset”. Please reboot after
configuration change.
2.5 Broadcast Storm Control
The Broadcast Storm Control discards broadcast frames when the number of cumulated non-unicast frames is over the
threshold, in order to prevent Network Traffic congestion bringing the Network to a halt. In this Switch, each port will drop
broadcast packets (Destination MAC ID is ff ff ff ff ff ff) after receiving continuous 64 broadcast packets. The counter will be reset
to0 every 800ms or when receiving any non-broadcast packets. (Destination MAC ID is not ff ff ff ff ff ff)

4 HELPFUL SUGGESTIONS
4.1 Prior to Installation
Before installing this Switch and connecting it to network devices, it is important to plan the network's layout. Things you should
consider include:
Dedicated Bandwidth: File servers and other high-traffic hardware improve their performance if they have their own dedicated
10Mbps or 100Mbps bandwidth.
Full-Duplex: Determine which devices support Full-Duplex connections.
Fast Ethernet: Make sure rules for cable lengths and categories are followed. 100BASE-TX and 100BASE-FX have different
rules for cable and distance.
Auto-Negotiation: Devices with different speeds may be easily swapped when the other end of the cableis fixed to a port with
Auto-Negotiation.
Crossover Uplink: This Switch can beUplinked to another Switch using any of the TP port.
4.2 Half- and Full-Duplex
This Switch supports both Half- and Full-Duplex modes for 10BASE-Tand 100BASE-TX.
ƍ In Half-Duplexmode data cannot betransmitted and received at the same time. Attached devices must finish transmitting data
before they can receive data.
ƍ In Full-Duplex mode data can be transmitted and received at the same time.
4.3 Auto-Negotiation
Every 10/100Mbps dual speed port on this Switch has a built-in "Auto-Negotiation" function. This technology automatically sets
thebest possiblebandwidth assoon as a connection is established with anothernetwork device (usually at Power “On” or Reset).
This capability is achieved via the Switch’s Auto-Negotiation function that automatically detects the modes and speeds the
second (attached) device is capable of.
Evaluating Auto-Negotiation Capability:
If the attached device is: This Switch Will Automatically Set Its TP Ports to Operate At:
100Mbps
noAuto-Negotiation 100Mbps Bandwidth (100BASE-TX, Half-Duplex)
100Mbps
with Auto-Negotiation 200Mbps Bandwidth (100BASE-TX, Full-Duplex)
10Mbps
noAuto-Negotiation 10Mbps Bandwidth (10BASE-T, Half-Duplex)
10Mbps
with Auto-Negotiation 20Mbps Bandwidth (10BASE-T, Full-Duplex)
Note: If the attached device is set to a fixed Forced Full-Duplex mode, it will not operate as an Auto-Negotiation device.
4.4 MAC Address Table
Every Ethernet data packet includes both source and destination addresses. This 6-byte ID is called the MAC (MediaAccess
Control) Address.
The Switch can automatically learn and store MAC addresses. However, the MAC address table is volatile: it disappears when
the Switch is powered “Off” or reset.
Note: When the network needs reconfiguration, we recommend turning off the power first.After all nodes have been moved,
Remove the power cord and re-attach it on the back panel to rebuild the internal MAC address table.
