LEDs Easy-to-read LED lights let you easily diagnose problems on the network and verify that all
computers are connected properly.
High
Performance
Networking
• Your switch can achieve speeds up to 200
Mbps in full duplex mode and seamlessly
integrates with any combination of 10BaseT,
100BaseTX, and 10/100 network adapters.
• Advanced Store and Forward technology
manages and optimizes data transfer by
efficiently channeling data to and from its
intended destination.
• Embedded on-chip memory creates a flow
control buffer to prevent data loss, even
during heavy network traffic.

Note: The cable length between your Ethernet Switch and hub/PC
should not exceed 100 meters. If you will operate at 10 Mbps
speed, use a Category 3 or 5 cable. If you will run your
network at 100 Mbps, use a Category 5 cable or better.
Note: Any type of hub or PC can connect to your Ethernet Switch by
using straight-through wires (not included). You can connect
your Ethernet Switch to other hubs or switches using any port
as an uplink port, increasing the number of PCs you can add
to your network.
