The FlexSwitch provides a special uplink feature on the Port 1 RJ45 connector. This
uplink connector is equipped with a crossover switch that can switch between the
receiving and transmitting wire pairs. This eliminates the need for a “crossed cable”
which is otherwise required for a connection to another switch or to a hub.
The fiber and UTP uplink modules provide displays to show data speed, link and activity,
half/full duplex status and collisions. Controls include half-duplex and full-duplex
switches for fiber ports on modules with fiber. The module with UTP ports (model
#6300) also features the crossover switch function on one port.
CONTROLS AND INDICATORS
FlexSwitch 600X Chassis:
(Models 6000, 6010, 6100, 6110)
Port 1 Control Switch
This switch provides the crossover feature for port 1 of the switch. It should be set to
the “straight” position for connection to a station or “crossover” position for connection
to a hub or a switch.

FlexSwitch 600X 10/100Tx UTP Plug-In Module:
(Model 6300)
The 10/100Tx module provides 8 additional UTP ports for the FlexSwitch 600X chassis.
Featuring the same 10/100 auto-sensing technology as the main chassis, this plug-in
serves to increase the port density to 32 ports.

SAMPLE APPLICATIONS
Application 1. 10/100 Workgroups with Fiber Backbone
This application depicts a typical 10/100 UTP switched workgroup network where a
variety of Fast Ethernet and legacy Ethernet workstations are connected to file servers
via fiber. In this example, 24-port FlexSwitch 600X switches (B) are used to connect
the workgroup stations (D). The workgroup switches are connected via fiber to the 6-
port FlexSwitch 600X3 fiber backbone switch (A). The file servers (C) are also connected
to the backbone server providing fair access to the servers from all workstations.
