Fast Ethernet
100 BASE-TX is a.ka. Fast Ethernet. With Fast
Ethernet data is sent 10 times as fast as with
traditional Ethernet (10 Mbps).
10 BASE T ports should have category , or 5
TP cables, and 100 BASE TX ports should have
category 5 TP cables.
If your 10 BASE T network uses category 5 TP
cables you can upgrade your network to a 100
BASE TX network by changing adaptors, hubs, etc.
Automatic rate selection
(N-Way Auto-Negotiation)
Every TP port has a built-in function for automatic
rate selection. This technique automatically sets
the broadest bandwidth immediately when the
connection is made with another device (usually
when the power is turned on or when resetting). The
function for automatic rate selection recognizes the
settings and rates of the different devices. Every port
has an Auto MDIX function which recognizes the
connected cable’s polarity and automatically adjusts
the switch to the correct polarity. The user only
needs to connect the device to an available 10/100
Mbps port.
MAC address list
Every data packet in the Ethernet contains both an
originating address and a destination address. This
6 byte ID is called the MAC address (Media Access
Control) address.
The switch can automatically store up to 1 K of
MAC addresses. They are deleted once the switch
is turned off or reset.
We recommend that the power be turned off
first before configuring the network. When all
connections have been moved, turn on the power
again in order to recreate the internal MAC address
list.
