1.0 INTRODUCTION

1.1 General Description

The 6750-FK is the replacement for the discontinued FlexSwitch Model
600XC 1Fx + 4U. The 6750-FK replacement kit consists of one
iConverter 10/100BASE-TX to 100BASE-FX Media Converter Module
and one iConverter 4Tx Switch Module installed in a iConverter 2-Module
Chassis.

The 6750-FK provides five auto-negotiating 10/100 UTP ports with auto-crossover
that enables easy attachment to hubs, switches and workstations. The
100BASE-FX fiber port supports half or full duplex operation.

The 6750-FK features on-board and front panel accessible DIP-switches for
manual configuration of the ports.

2.0 INST ALLATION

2.1 Chassis Installation

The 6750-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
backplanes enabled on both modules and Link Segment selected (see Section

6.0). 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 module. 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 10BASE-T or 100BASE-TX
Ethernet devices.

3.0 CONFIGURATION

3.1 DC Powered Chassis Site Preparation

• Power source should be available within 5 ft. of the chassis. The over
current protection for connection with centralized DC shall be provided in
the building installation, and shall be a UL listed circuit breaker rated
20Amps, and installed per the National Electrical Code, ANSI/NFPA-70.

• This equipment requires 18-60VDC/1.0Amp rated power. Appropriate
overloading protection should be provided on the DC power source outlets
utilized.

WARNING: Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to theDC-input power supply.

WARNING REGARDING EARTHING GROUND:

o

This equipment shall be connected to the DC supply
system earthing electrode conductor or to a bonding
jumper from an earthing terminal bar or bus to which the
DC supply system earthing electrode is connected.

o

This equipment shall be located in the same immediate
area (such as adjacent cabinets) as any other equipment
that has a connection between the earthed conductor of
the same DC supply circuit and the earthing conductor,
and also the point of earthing of the DC system. The DC
system shall not be earthed elsewhere.

o

The DC supply source is to be located within the same
premises as this equipment.

o

There shall be no switching or disconnecting devices in
the earthed circuit conductor between the DC source and
the earthing electrode conductor.

• 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 weight of other equipment.

3.2 DC Powered Chassis Mounting

• Locate the DC circuit breaker, and switch the circuit breaker to the OFF

position.
