Normal/Uplink Push Button
The Normal/Uplink push button on the front panel of the switch allows you to
select uplink (MDI) or normal (MDI-X) wiring for port 8 on the Model FS308
switch. These ports are configured for normal wiring to connect to a PC when
the push button is in the out position. When the push button is pressed in, these
ports are configured for uplink wiring to connect to another switch or to a hub,
using a straight-through twisted pair cable.
Rear Panel
The rear panel of the Model FS308 switch has eight autosensing 10/100 Mbps
Ethernet ports. The rear panel also has full-duplex (FDX) and auto-duplex
(AUTO) toggle switches and a power adapter receptacle for the supplied power
cord.

FDX/AUTO Duplex Toggle Switches
One full-duplex (FDX) and auto-duplex (AUTO) toggle switch is assigned to
each 10/100 Mbps port, enabling the communication mode to be set to either
full-duplex or auto-duplex mode. Full-duplex mode doubles throughput of
point-to-point connections by letting individual ports transmit and receive
concurrently when the connecting device also supports full-duplex mode.
Setting the toggle switch to AUTO on the 10/100 Mbps port enables the port to
determine duplex mode by coordinating with the remote port. In most cases, the
toggle switch should be set to AUTO. If the remote port is a repeater or hub or
cannot provide the proper signal to indicate its duplex capability, the port
defaults to half-duplex mode.
Set the port to full-duplex mode only if the remote device is full-duplex capable
but cannot provide the proper signal to indicate so.
