Introduction
Micronet SP616R provides powerful, high-performance Ethernet
switch, with all ports capable of 10 and 100Mbps auto-negotiation
operation.
Store-and-forward switching mode promises the low latency plus
eliminates all the network errors, including runt and CRC error
packets. To work under full-duplex mode, transmission and
reception of the frames can occur simultaneously without causing
collisions as well as double the network bandwidth.
The switch is plug-n-play without any software to configure and also
fully compliant with all kinds of network protocols. Moreover, the
diagnostic LEDs on the front-panel can provide the operating status
of individual port and whole system.

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.
Cable Selection
Refer to the following table：
Network Speed Cable Type Max. Length
10Mbps Cat. 3, 4, 5 UTP/STP 100 meters
100Mbps Cat. 5 UTP/STP 100 meters
Note: To prevent costly equipment damage and downtime, please
consider installing a surge suppression device or a UPS
(Un-interrupted Power Supply).

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.

11
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).
