Q:
What are Stackable Fast Ethernet and Gigabit Ethernet Switches?
A:
As the power of workstations and business applications increase, heavier demands are made on the available network bandwidth that, if unchecked, can lead to performance problems in a hub-based setup. The Stackable Fast Ethernet and Gigabit Ethernet Switches allow your network to be segmented so that traffic can be contained effectively, reducing the overall load without affecting access to critical resources.

Q:
How does a switch work?
A:
When a network of repeater hubs is in operation, any information that is sent by the workstations is passed around the whole network (regardless of the destination of the information). This can result in a lot of unnecessary traffic that can slow the network down. The Switch solves this problem because it `listens' to the network and automatically learns what workstations can be reached through its ports. It can then selectively pass on any information by transmitting the traffic from the relevant port only (instead of all ports like a repeater hub). This operation is called `switching'.
The Switch effectively divides up your network, localizing the network traffic and passing on traffic as necessary. If you have workstations that communicate frequently in the same part of the network, traffic between them is not passed to the remainder of the network, reducing the load. If you have any high performance workstations that require a lot of bandwidth, connect them directly to the Switch.

Q:
Can I connect 10BASE-T and 100BASE-TX Networks?
A:
The 10/100 ports can each be connected to either a 10BASE-T or 100BASE-TX network. If you have both types of networks, you can connect them using the Switch so that all your workstations can communicate. Alternatively, if you use 10BASE-T and want to improve performance by introducing 100BASE-TX, the Switch protects your investments because it maintains 10BASE-T connections to your original network equipment.
