2. Introduction To SP659A 10/100/1000M Smart Switch
2.1 General Description
Micronet SP659A is a powerful, high-performance 10/100/1000 Mbps Fast
Ethernet and Gigabit switch, with all 24 ports capable of 10 or 100Mbps
auto-negotiation operation (NWay), which means the switch could
automatically negotiate with the connected partners on the network speed and
duplex mode. Moreover, the 10/100Mbps auto-sensing ability provides an easy
way to migrate 10Mbps to 100Mbps networks with no pain. Compared to the
shared 10Mbps or 100Mbps networks, the switch delivers a dedicated
10/100Mbps connection to every attached client with no bandwidth congestion
issue.
Another two are Gigabit copper ports, which also support auto-negotiation
operation, auto MDI crossover function and full-duplex mode. They are ideal for
micro-segmenting large networks into smaller, connected subnets for improved
performance, enabling the bandwidth demanding multimedia and imaging
applications. The Gigabit ports also provide the fat pipe to the servers or
backbone connection for boosting the total system performance.
The switch also supports more value-added function include port trunk
and virtual LAN. Port trunk function could be used to build up a fat pipe up to
800Mbps between switches that will solve the bandwidth bottleneck on
backbone connection. Port-based virtual LAN provides system security function,
which keeps the resources only could be shared in the same virtual group and
all the other nodes do not belong to the group can not access the resources.
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 rich diagnostic
LEDs on the front-panel for providing the operating status of individual port
and whole system.

3.1 Installing The SP659A 10/100/1000M Smart Switch
The switch does not require software configuration. Users can immediately
use most of the features of this product simply by attaching the cables and
turning the power on.
3.1.1 Desktop Installation
For desktop installation, the switch needs to put on a clean, flat desk or
table close to a power outlet. Plug in all network connections and the power
cord, then the system is ready.
When deciding where to put the switch then you must ensure:
 It is accessible and cables can be connected easily
 Cabling is away from - Sources of electrical noise such as radio, transmitters,
broadband amplifiers, and fluorescent lighting fixtures.
 Water or moisture can not enter the unit
 Air flow around the unit and through the vents in the side of the case is not
restricted (company recommend that you provide a minimum of 25mm
inch clearance)
To prolong the operational life of your units:
 Never stack units more than eight sets high if freestanding.
 Do not place objects on top of any unit or stack
 Do not obstruct any vents at the sides of the case
3.1.2 Rack-Mount Installation
The switch may standalone, or may be mounted in a standard 19-inch
equipment rack. Rack mounting produces an orderly installation when you have
a number of related network devices. The switch is supplied with two mounting
brackets and screws. These are used for rack mounting the unit.
Rack Mounting the Switch
The switch should be able to fit in the 19 inches rack.
1. Disconnect all cables from the switch before continuing.
2. Place the unit on a hard, flat surface with the front facing toward you.
3. Locate a mounting bracket over the mounting holes on one side of the unit.
4. Insert the screws and fully tighten with a suitable screwdriver.
5. Repeat the two previous steps for the other side of the unit.

11
6. Insert the unit into the 19" rack and secure with screws (not provided).
7. Reconnect all cables.
3.1.3 Installing Network Cables
After placing the switch on the desktop, then we need to know how to
connect the device to network.
3.1.3.1 Station Connections with Twisted-Pair Cable
Connect each station to the switch by a Category 5 or Category 5E
twisted-pair cable (straight-through or cross-over cable). Plug one RJ-45
connector into a front-panel port of the switch, and plug the other RJ-45
connector into the station’s network adapter.
3.1.3.2 Switch to Switch Connections with Twisted-Pair Cable
In making a switch to switch connection, you could use any port to connect
another switch with straight-through or cross-over cable. As the 10/100Mbps
ports support auto MDI-X function, so the connection is independent of cable
type. allow using a straight cable to make a switch to switch connection.
In order to increase the bandwidth between switch and switch, you could
enable the port trunk function or Gigabit ports to connect each other.

4. Switch Operation
4.1 MAC Address Table and Learning
The switch is implemented with a MAC address table which is composed
of many entries. Each entry is used to store the address information of network
nodes on the network, including MAC address, port ID, etc. The information is
the most important base to do packet filtering and forwarding.
When one packet comes in from any port, the switch will learn the source
address, port ID, and the other related information in address table. Therefore,
the content of the MAC table will update dynamically.
4.2 Filtering and Forwarding
When one packet comes in from any port of the switch, it will check the
destination address besides the source address learning. The switch will look up
the address table for the destination address. If not found, this packet will be
forwarded to all the other ports except the port in which this packet comes. If
found, and the destination address is located at different port from this packet
comes in, the packet will be forwarded to the port where this destination
address is located according to the information of address table. But, if the
destination address is located at the same port as this packet comes in then this
packet will be filtered.
4.3 Store and Forward
Store-and-forward is one kind of packet-forwarding methodology. As a
store-and-forward switching hub, it will store the complete packet in the
internal buffer and do the complete error checking before transmitting to the
network. Therefore, no error packets will disturb the network. It is the best
choice when a network needs efficiency and stability.
