1.0 INTRODUCTION
1.1 General Description
The 6540-FK is the direct replacement for the discontinued FlexSwitch Model
600XC 2Fx + 2U. The 6540-FK replacement kit consists of two iConverter
10/100Base-Tx to 100Base-Fx Media Converter Modules installed in a iConverter
2-Module chassis.
The 6540-FK provides two 10/100 auto-negotiating UTP ports with auto-crossover
and two 100Base-Fx fiber ports.
The two 100Base-Fx fiber ports support half or full duplex operation.
The 6540-FK features front panel accessible DIP-Switches for convenient
configuration of the single UTP and fiber port. On-board DIP-Switches
configure the link mode and backplane operation. The backplane is enabled
by default.

2.0 INST ALLATION
2.1 Chassis Installation
The 6540-FK is designed to accommodate wall-mounting and tabletop
installations. For wall-mounting, the 8249-0 W all-Mount kit (sold separately)
is designed to attach the chassis to a wall, backboard or other flat surfaces.
For tabletop installations, place the unit on a flat level surface. Attach the
rubber feet to the bottom of the chassis to prevent the unit from sliding. Make
sure the unit is placed in a safe, dry and secure location.
For external power installation and configuration, see section 3.0.
2.2 Module Installation
The modules are pre-installed in the iConverter 2-Module chassis with the
backplane enabled on both modules and Link Segment selected. If the modules
are removed, carefully slide the module into the open slot. Align the module
with the installation guides and ensure that the module is firmly seated against
the backplane. Secure the module by fastening the front panel thumbscrew
(push in and turn clockwise to tighten) to the chassis front.
2.3 Fiber Installation
Connect an appropriate multimode or single-mode fiber cable to the fiber port
of the installed modules. It is important to make sure that the transmit (TX) is
attach to the receive side of the device at the other end and the receive (RX) is
attach to the transmit side.
2.4 UTP Installation
Connect the UTP ports via a Category 5 cable to a 10Base-T or 100Base-Tx
Ethernet device.

3.0 CONFIGURATION
3.1 AC Site Preparation
• Power source should be available within 5 ft. of the chassis and installed
per the National Electrical Code ANSI/NFPA-70.
• This equipment requires a 100-240VAC, 0.5Amp, 50/60Hz power outlet.
Appropriate overloading protection should be provided on the AC power
source outlets utilized.
• The operating temperature of this equipment is 0 to 50 degrees C. If installed
in a closed or multi-module rack assembly, the operating ambient
temperature of the rack must not exceed the maximum rated 50 degrees C.
• Installation of the equipment should be such that the air flow in the front
and back of the chassis is not compromised or restricted.
• Never use this equipment to carry any weight except its own. Never use it
as a shelf to support the weight of other equipment.
3.2 AC Powered Chassis Mounting
Attach the AC power cord to the back of the Power Receptacle and plug into
the AC outlet. Any installed modules will illuminate the power LED.

3.3 Configuring the DIP-Switches
The 6540-FK has been pre-configured with Auto-Negotiation enabled on all
UTP ports for plug and play easy of use. However, the iConverter modules
offer additional configuration flexibility.
3.3.1 Media Converter Modules - Front Panel
The Media Converter Modules have been pre-configured as illustrated below .
Using the front panel DIP-Switch, the module can be re-configured for customer
specific applications.
Media Converter Module Front Panel DIP-Switch
Fiber Full/Half-Duplex “FDX / HDX” DIP-Switch
When in the Fiber Full/Half-Duplex DIP-Switch is in the “FDX” position
(factory default), the fiber port operates in Full-Duplex mode. When in the
“HDX” position, the fiber port operates in Half-Duplex mode and its distance
is limited by the IEEE 802.3 standard to 412 meters.
UTP Auto/Manual Negotiate “AN / MAN” DIP-Switch
When the UTP “AN/Man” DIP-Switch is in the Auto-Negotiate “AN” position
(factory default), the converter Auto-Negotiates and matches the 10/100 speed
and duplex mode of a mating Auto-Negotiating device connected to its UTP
port.
When the UTP “AN/Man” DIP-Switch is in the “Man” position, the converter
does not auto-Negotiate and operates in the mode selected by the Full/Half
Duplex “FDX/HDX” and “10/100” DIP-Switches.
UTP 10/100 “10 / 100” DIP-Switch
When the UTP “AN/Man” DIP-Switch is in the “Man” position, the UTP
“10/100” DIP-Switch selects the speed of the UTP port. When in the “100”
position (factory default), the UTP port operates at 100 Mbps. When in the
“10” position the UTP port operates at 10 Mbps.
UTP Full/Half-Duplex “FDX / HDX” DIP-Switch
When the UTP “AN/Man” DIP-Switch is in the “Man” position, the “FDX/HDX”
DIP-Switch selects the duplex mode of the UTP port. When in the “FDX” position
(factory default), the UTP port operates in Full-Duplex mode. When in the
“HDX” position, the UTP port operates in Half-Duplex. Set the duplex mode
to match the connecting device and check for link status.
Page 6
Note: Attaching the Auto-Negotiating UTP port of the 6540-FK to a device
with a manual/forced /hard-coded UTP port may result in an unpredictable
port setting with excessive collisions and poor link performance. When
operating in Manual mode, both mating ports MUST be set manually to the
same speed and duplex mode.
3.3.2 Media Converter Modules - On-Board
The Media Converter Modules have on-board DIP-Switches for the
configuration of the Link Modes and Backplane connectivity . See Section 6.0
for more information on the Link Modes. The modules are pre-configured as
illustrated below.

Not Used (Factory Set)
When the Remote Fault Detect “RFD” DIP-Switch is in the UP position, the
RFD mode is selected. When in the DOWN position (factory default), the
RFD mode is disabled.
Note: Connecting two converters with both set to RFD mode is an illegal
setting and will cause a “deadly embrace” lockup.
A and B Backplane Enable “BPOEN” DIP-Switch
This DIP-Switch must be in the UP position (factory default) for the module to
operate correctly. The backplane must be enabled for the Media Converter
Modules to communicate.
Link Propagate/Link Segment “LP” DIP-Switch
When both the Link Propagate/Link Segment “LP” and the Remote Fault Detect
“RFD” DIP-Switches are in the DOWN position (factory default), Link Segment
mode is enabled. When the Link Propagate/Link Segment “LP” DIP-Switch is
in the UP position, and the Remote Fault Detect “RFD” DIP-Switch is in the
DOWN position, Link Propagate mode is enabled.
Note: Setting both the “LP” and the “ RFD” to the UP positions on the same
module is an illegal mode that will result in unpredictable behavior.

4.0 LED INDICA TORS
4.1 Media Converter Modules
The Media Converter Modules have LED indicators to provide information
on how the module is communicating to its link partner. The LED indicators
can also be used to troubleshoot problems with the connections.

6.0 LINK MODES
In order to accommodate different user requirements, the 6540-FK Media
Converter Modules support three different link modes:
Link Segment (LS)
LS mode transmits a link signal independently of any received ‘Link’ at any
port. Utilizing this configuration, a loss of a receive link signal will only affect
the port detecting the loss of signal. All the other ports will continue to generate
a link signal. A loss of link on the UTP port, only affects the UTP port; the
other ports remain unaffected.
Link Propagate (LP)
LP mode transmits a link signal only when a link signal is detected. Utilizing
this configuration, a loss of a receive link signal will continue to “propagate”
through to the next port in the network. A loss of link on the UTP port will
cause the fault to propagated forward causing the fiber and UTP ports at the
remote end to drop its link. This setting allows the loss of a link to be detected
by SNMP or other managed network devices.
Remote Fault Detect + Link Propagate (RFD+LP)
RFD+LP mode transmits a link signal only when a link signal is detected.
When a loss of link is detected, this mode will perform both a loop back and
propagate forward. A loss of RX fiber causes the fault to loop back causing
the port on the other media converter to lose link. It also propagates the fault
forward toward the UTP port causing the UTP port to lose link.
Note: Connecting two converters together both set to RFD+LP mode will
cause a lockup condition. This is an illegal setting.
