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.
