Front-Panel Description
The front panel of the hubs provides 10BaseT/100BaseTX network ports, a
10BaseT/100BaseTX uplink port, a set of LEDs, and a Mode button.

Network and Uplink Ports
The front of each hub provides autosensing 10BaseT/100BaseTX network and uplink ports
(see Figure 1-2). These ports, hereafter referred to as 10/100 ports, can operate at either 10
or 100 Mbps. When connected to another device, each 10/100 port senses the speed setting
of that device and advertises its own capabilities. If the connected device also supports
autonegotiation, the 10/100 port negotiates the best connection it can and configures itself
accordingly. If the other device does not autonegotiate, the 10/100 port operates at
10 Mbps. You can also explicitly set the 10/100 ports to operate at 10 or 100 Mbps by using
one of the management interfaces available to the FastHub 400M models.

Front-Panel Ports
The 10/100 ports are compatible with the IEEE 802.3 10BaseT and IEEE 802.3u
100BaseT standards. These ports use standard RJ-45 connectors, and you can connect these
ports to 10BaseT-compatible devices through Category 3, 4, or 5 twisted-pair cabling. You
can also connect these ports to 100BaseTX-compatible devices through Category 5 cabling.
