About the Switch
The Stratix 2000  Ethernet unmanaged switch can be used to divide an Ethernet network
into segments, and to direct network traffic more efficiently than using repeating hubs.
This allows for a larger network size, regardless of the amount of network traffic.
Connecting one of the switch ports to a single device segments the network, letting you
dedicate bandwidth to that device. Unmanaged switches also enable multiple
simultaneous communication between devices on different ports.
The individual ports autonegotiate link speeds (10 Mbps or 100 Mbps). To improve data
throughput, traffic is restricted to ports in a data exchange, while other data is
simultaneously exchanged on other ports.
Features supported by the Ethernet unmanaged switches include the following:
•
10 Mbps or 100 Mbps, full- or half-duplex communication, per copper port
autonegotiation
•
Automatic crossover detection (auto MDIX)
Before You Begin
Observe these guidelines before installing the switch:
•
For 10/100 ports, the cable length from a switch to an attached device cannot
exceed 100 m (328 ft).
•
Clearance to front and rear panels must meet these conditions:
–
Front-panel status indicators can be easily read.
–
Access to ports is sufficient for unrestricted cabling.
–
DC (or AC) power connectors are within reach of the connection to their power
source.
IMPORTANT The device you connect to a switch must have its Ethernet port configured for autonegotiate to
avoid confusion between half- and full-duplex communication. You can also set the device’s
Ethernet port to half-duplex. Failure to do so may result in higher error rates.
