Model FS102, Model FS104, Model FS108 Fast Ethernt Switch Installation Guide
3. Set the FDX or AUTO toggle switches on the rear panel for the selected duplex mode.
A hub and repeater use a common collision domain for all communications and cannot
support full-duplex mode. When connecting any of the 10/100 Mbps ports on the switch to a
hub, set the port to AUTO. The switch must also be set to AUTO when connecting to any
device that does not use NWay autonegotiation to detect the operating mode. Setting the
toggle switch to AUTO will cause the port to default to half-duplex mode when connecting to
a port that does not use autonegotiation.
When connecting to a PC, a server, or another switch, the duplex setting for the port must be
the same as the duplex setting on the PC, server, or other switch.
To set the 10/100 Mbps ports for the selected duplex mode:
• Move the toggle switch into the down position (to AUTO) for auto-duplex mode.
The 10/100 Mbps ports will negotiate and automatically determine the duplex mode
based on the mode of the connected port. If the connected port cannot autonegotiate,
the 10/100 Mbps port will default to half-duplex mode. The factory setting of the duplex
toggle switches is AUTO.
• Move the toggle switch into the up position (to FDX) for full-duplex mode.The duplex
switch must be set to FDX if you are connecting to legacy full-duplex 100 Mbps devices
that do not generate signals indicating duplex mode. If the duplex switch is set to AUTO
mode, the 10/100 Mbps ports will default to half-duplex mode because the port does not
receive the proper signal.
4. Connect one end of the DC power adapter cable to the power outlet on the rear panel of
the switch and the other end of the power adapter cable to the wall outlet.
When power has been applied to the switch:
• The green Pwr (Power) LED on the front panel is on.
• The green Link LED on each connected port is on.
When the switch is connected and operating, refer to the table in “LEDs” for information about
the LEDs and their activity.
