1) Congure DIP-Switches
The 6550-FK has been pre-congured with Auto-Negotiation enabled on all RJ-45 ports for
plug and play easy of use. However, the iConverter Modules offer additional conguration
exibility.
4 Port Switch Module
Each 4-Port Switch Module has been pre-congured for Auto-Negotiation with Backplane
A and B Enabled.
4 Port Switch Module Default DIP-Switch Settings
Backplane Port A Enable/Disable
This DIP-Switch must be in the LEFT “Enable” position for the module to operate correctly.
The switch provides backplane connectivity with the other switch module.
Backplane Port B Enable/Disable
This DIP-Switch must be in the LEFT “Enable” position for the module to operate correctly.
The switch provides backplane connectivity with the other switch module.
Port 1 and Port 2 RJ-45 Auto-Negotiate/Manual
When this DIP-Switch is in the RIGHT “AN” position, the Port automatically determines the
speed and duplex mode of the connecting copper device. If the connecting device cannot
provide the proper signal to indicate its own mode of operation, this DIP-Switch should be
set to the LEFT “Man” position. Manual mode requires manually conguring the RJ-45 port
to match the speed and the duplex mode of the connecting device using the Speed and
Duplex DIP-Switches.
When a port is congured for Auto-Negotiation, the automatic crossover detection is enabled
for that particular port. Automatic crossover detection is disabled when the port is congured
for manual negotiation.
Port 1 and Port 2 Speed 10/100Mbps
When the port is congured for Manual Mode (AN/MAN in the LEFT position), the Speed
DIP-Switch determines the speed of operation for the designated port. Setting the Speed
DIP-Switch to the RIGHT “100” position forces the port to operate at 100Mbps. Setting this
DIP-Switch to LEFT “10” position forces the port to operate at 10Mbps. Adjust the Speed
DIP-Switch to match the speed of the connecting device.
Port 1 and Port 2 Duplex Full/Half-Duplex
When the port is congured for Manual Mode (AN/MAN in the LEFT position), the Duplex
DIP-Switch determines the duplex operation mode for the port. Setting the Duplex DIP-
Switch to the RIGHT “FD” position forces the port to operate in Full-Duplex. Setting this
Page 2

Page 3
DIP-Switch to the LEFT “HD” position forces the port to operate in Half-Duplex. Adjust the
Duplex DIP-Switch to match duplex mode the connecting UTP device.
When a port is congured for Auto-Negotiation, the Duplex DIP-Switch will determine if the port
advertises Full-Duplex or Half-Duplex. When the Duplex DIP-Switch is in the “FD” position,
the port advertises Full-Duplex and Half-Duplex capability. When in the Duplex DIP-Switch
is in the “HDX” position, the port advertises only in Half-Duplex capability.
Fiber Module - Front Panel
The modules have been pre-congured as illustrated below. Using the front panel DIP-
Switches, the module can be recongured for customer-specic applications.
Fiber Module Front Panel Default DIP-Switch Settings
Fiber Full/Half-Duplex
When in the Fiber Full/Half-Duplex DIP-Switch is in the “FDX” position, the ber port operates
in Full-Duplex mode. When in the “HDX” position, the ber port operates in Half-Duplex
mode and its distance is limited by the IEEE 802.3 standard to 412 meters.
UTP Auto/Manual Negotiate
When the UTP “AN/Man” DIP-Switch is in the Auto-Negotiate “AN” position, the converter
Auto-Negotiates and matches the 10/100 speed and duplex mode of a mating Auto-Negotiating
device connected to its RJ-45 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
When the UTP “AN/Man” DIP-Switch is in the “Man” position, the UTP “10/100” DIP-Switch
selects the speed of the RJ-45 port. When in the “100” position (factory default), the RJ-45
port operates at 100 Mbps. When in the “10” position the RJ-45 port operates at 10 Mbps.
UTP Full/Half-Duplex
When the UTP “AN/Man” DIP-Switch is in the “Man” position, the “FDX/HDX” DIP-Switch
selects the duplex mode of the RJ-45 port. When in the “FDX” position, the RJ-45 port operates
in Full-Duplex mode. When in the “HDX” position, the RJ-45 port operates in Half-Duplex.
Set the duplex mode to match the connecting device and check for link status.
Note: Attaching the Auto-Negotiating RJ-45 port of the 6540-FK to a device with a manual/
forced /hard-coded RJ-45 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.
On Board DIP-Switches
The modules have on-board DIP-Switches for the conguration of the Link Modes and
Backplane connectivity. For more information on Link Mode, see the Link Mode Application
Note.
The modules are pre-congured as illustrated below.

When the Remote Fault Detect “RFD” DIP-Switch is in the UP position, the RFD mode is
selected. When in the DOWN position, 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
This DIP-Switch must be in the UP position for the module to operate correctly. The backplane
must be enabled for the modules to communicate.
Link Propagate/Link Segment
When both the Link Propagate/Link Segment “LP” and the Remote Fault Detect “RFD”
DIP-Switches are in the DOWN position, 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.
