Installation  
Micronet SP616R Switches do not require software configuration.  
Users can immediately use any of the features of this product simply  
by attaching the cables and turning on the power.  
Rack Mounting  
The switch can be mounted in an EIA standard 19-inch rack, which  
can be placed in a wiring closet with other equipment. Attach the  
mounting brackets at the switch’s front panel (one on each side),  
and secure them with the provided screws.  
Then, use screws provided with the equipment rack to mount each  
switch in the rack.  
Station Connections  
Connect each station to the switch by twisted-pair cable. Plug one  
RJ-45 connector into a RJ-45 port of the switch, and plug the other  
RJ-45 connector into the station’s network adapter. Power on the  
switch and then system is ready.  
It supports Auto-Negotiation function to automatically select optimal

speed (10/100Mbps) and mode (Full/Half Duplex). If the attached  
device does not support auto-negotiation or has auto-negotiation  
disabled, an auto-sensing process is initiated to select the speed  
and set the duplex mode to half-duplex.  
Switch-to-switch Connections  
In making a switch interconnection, you could use any port to  
connect another switch with straight or crossover cable. As all the  
ports support auto-uplink (MDI / MDI-X) function, using a  
straight cable to make a switch-to-switch connection is  
allowed.

Appendix  
A. Fast Ethernet Technology  
The growing importance of LANs and the increasing complexity of  
desktop computing applications are fueling the need for high  
performance networks. A number of high-speed LAN technologies  
have been proposed to provide greater bandwidth and improve  
client/server response times. Among them, 100BASE-TX (Fast  
Ethernet) provides a non-disruptive, smooth evolution from the  
current 10BASE-T technology. The non-disruptive and smooth  
evolution nature, and the dominating potential market base,  
virtually guarantees cost effective and high performance Fast  
Ethernet solutions in the years to come.  
100Mbps Fast Ethernet is a new standard specified by the IEEE  
802.3 LAN committee. It is an extension of the 10Mbps Ethernet  
standard with the ability to transmit and receive data at 100Mbps,  
while maintaining the CSMA/CD Ethernet protocol. Since the  
Switch is compatible with all 10Mbps Ethernet environments, it  
provides a straightforward upgrade and takes advantage of the  
existing investment in hardware, software, and personnel training.  
B. Switching Technology  
Another approach to pushing beyond the limits of Ethernet  
technology is the development of switching technology. A switch  
bridges and transmits Ethernet packets at the MAC address level  
of the Ethernet protocol, among connected Ethernet or Fast  
Ethernet LAN segments.

Switching is a cost-effective way of increasing the total network  
capacity available to users on a local area network. A switch  
increases capacity and decreases network loading by dividing a  
local area network into different segments. Each segment has its  
own bandwidth and it does not compete with others for network  
transmission capacity.  
A switch acts as a high-speed selective bridge between the  
individual segments. The switch forwards traffic from origin  
segment to destination segment, without interfering with any other  
segments. By doing this, the total network capacity is multiplied,  
while still maintaining the same network cabling and adapter cards.  
For Fast Ethernet networks, a switch is an effective way of  
eliminating problems of uplinking Fast Ethernet hubs beyond the  
“two-repeater limit”. A switch can be used to split parts of the  
network into different collision domains, making it possible to  
expand your Fast Ethernet network beyond the 205-meter network  
diameter limit. The switch supports both traditional 10Mbps  
Ethernet and 100Mbps Fast Ethernet, which is also ideal for  
bridging between the existing 10Mbps networks and the new  
100Mbps networks.  
LAN Switching technology is a marked improvement over the  
previous generation of network bridges, which were criticized by  
their higher latencies. Routers have also been used to segment  
local area networks. But, the router expensive, difficult to setup,  
and maintenance intensive, these make it relatively impractical for

the network. Switch, on the other hand, is less expensive, easier to  
setup, and practically maintenance free, which make it an ideal  
solution to today’s local area network congestion problems.  
C. RJ-45 Pin Assignment  
According to the EIA/TIA 586B standard, the color sequence of  
Cat.5 UTP is as following figure. The Straight-through cable is used  
to connect between switch and PC. The Cross-over cable is used  
to connect between two switches without auto uplink (auto  
MDI/MDI-X).
