Installation
Micronet SP676A/SP684A Gigabit Switch is plug-n-play without any
software to configure and also fully compliant with all kinds of
network protocols.
The switch provides 16/24 RJ-45 ports of 10/100/1000M. Just
connect your stations to it and play. Four mini-GBIC slots are
optional. They are respectively shared with last 4 ports but have
higher priority than the RJ-45 ports. If both RJ-45 ports and
mini-GBIC slot are in use, the system will automatically detect
mini-GBIC slots first. The mini-GBIC slot will be active, and the
RJ-45 port will be disabled and ignored.
All ports could be used to connect with another switch. As all the
ports support auto-uplink (MDI / MDI-X) function, user can choose
to use a straight cable or a crossover cable to make a
switch-to-switch connection.
For cable selection, refer to the following table
Introduction
Micronet SP676A/SP684A Gigabit switch offers practical Ethernet
switching solutions for enterprises and business. The16/24 Gigabit
ports provide the fat pipe to the server or backbone connectivity for
boosting the total system performance and allowing non-blocking
throughput where it needed. Also, it is perfect for graphics,
multimedia, and other applications that have to move large files
across the network quickly. In addition to the cooper ports, one of
the ports supports fiber connection with the equipped Mini-GBIC
ports for obtaining long-distance communication.
All ports support auto-uplink detection, so users don't have to worry
about the cable type. Each port will automatically communicate for
best speed and to run in half- or full-duplex mode.
Store-and-forward switching prevents damaged packets and
network errors from being passed on into the network.
