“RFD” Remote Fault Detection:
When the “RFD” dip-switch is in the “UP” position, the
RFD mode is selected. When in the “DOWN” position
(factory setting), the RFD mode is disabled.
Description:
The DFCS 10/100T-Fx converters support the IEEE 802.3
Ethernet standard and convert between Ethernet 10Base-T
or 100Base-Tx unshielded twisted pair (UTP) and Fast
Ethernet fiber 100Base-Fx. Models are available for
multimode (MM) and single-mode (SM) dual-fiber, and singlemode single-fiber.
The 10/100T-Fx supports Half-Duplex and Full-Duplex
modes and features a cross-over UTP switch for easy
attachment to hubs, switches and workstations.
The 10/100T-Fx can be used as a standard two port UTP
to fiber converter. It can also use its two additional
10/100 backplane ports to connect to adjacent modules
and accommodate flexible network configurations like
in-band management and multi-module configurations.
The 10/100T-Fx can be used in an unmanaged or managed
fashion. When unmanaged, it can be installed in a chassis
without a Network Management Module (NMM). To be managed,
a NMM module must be installed in the same chassis.
Port Structure:
Using a 4-port-switch design, the 10/100T-Fx features the
two traditional front-plane 10/100 UTP and 100Mbps fiber
ports and two 10/100 Ethernet backplane ports (“A” and “B”)
that can connect to adjacent modules within the same chassis.
When the 10/100T-Fx A and B ports are enabled (using
the “BPOEN” dip-switch), they connect via the chassis’
backplane to the slots on the left and right sides of the
10/100T-Fx module. When another switch-based module
with backplane port connections such as a second
10/100T-Fx or a NMM is installed in an adjacent slot, it can
be connected via the backplane to the 10/100T-Fx to
facilitate a multi-module configuration.

“FLOWEN” Dip-Switch:
This switch is for factory use only and should always be
left in the ”DOWN” (factory setting) position.
Mounting and Cable Attachment:
DFCS modules are hot-swappable and can be installed
into any DFCS chassis.
1. Using the chassis’ module guides for alignment, insert the
module into the selected slot and secure using the front
panel fastener screw.
2. Using a Category 5 cable attach the UTP port to a mating
10 or 100Base-Tx Ethernet device port.
3. Using a multimode or single-mode dual-fiber cable as
required per the converter type, attach the fiber port
to a 100Base-Fx mating Ethernet device. The transmit
(Tx) must attach to the receive side of the mating
device and the receive (Rx) must attach to the transmit
side.
4. Single fiber (SF) converters must be used in matched
pairs. The transmit (Tx) and receive (Rx) wavelengths
of one converter must match the receive (Rx) and
transmit (Tx) wavelengths of the mating converter.
Only single-fiber cable is required to connect the mating
devices.
5. Set the BPOEN backplane switch enable as needed.
6. While in LS mode (RFD and LP “DOWN”), select the
required Duplex mode using the fiber FDX/HDX and the
Page 7
Page 8
Connecting two converters with both set to RFD
mode is illegal and will cause a “deadly embrace”
lockup.
“LP” Link Propagate/Segment Dip-Switch:
When in the ”DOWN” (factory setting) position (and the
“RFD” dip-switch is in the “DOWN” position), the LS mode
is selected. When in the “UP” position, LP mode is selected.
Note that for LS mode, both the “LP” and “RFD” dipswitches must be in the DOWN position (factory setting).
Note that 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.
“BPOEN” A and B Back-Plane Link Enable Dip-Switch:
When the “BPOEN” dip-switch is in the “UP” position, both
the A and B backplane ports are enabled and connect to
the backplane. When the “BPOEN” switch is in the “DOWN”
position (factory setting), both ports are disabled and
disconnected from the backplane.

Fig. 1, depicts a chassis with three modules plugged into
three of its adjacent backplane slots. The adjacent slots
are connected via the backplane using the “A” and “B”
10/100 links. In this example, the 10/100T-Fx in the center
slot connects to the slot on its left using the A link and to
the slot on its right using the B link.
In this example, the module on the left is a Network
Management Module (NMM) and it connects via its A
backplane port to the 10/100T-Fx facilitating “In-Band”
management (via the fiber uplink). The module on the
right is a 4-port 10/100 switch module (4Tx/L2) and it
connects via its B link port to the 10/100T-Fx facilitating
a 5-port 10/100 Ethernet switch with a fiber uplink
configuration. This 3-module configuration provides an
effective 5-port 10/100 managed switch with a fiber uplink
configuration.
This example shows how the 10/100T-Fx can be used
either as a traditional managed or unmanaged media
converter or to create flexible and effective network

In “Link Segment” (LS), sometimes referred to as the
“Normal” mode, a port transmits a “Link” signal
independently of any received “Link” at any other port.
For example, the UTP transmits a “Link” regardless of
the fiber receiving a “Link” [Fig 2(b)].
the 10/100 speed and duplex mode of a mating autonegotiating device connected to its UTP port.
In “Link Propagate” (LP), sometimes referred to as
“Link Loss Carry Forward”, a port transmits a “Link”
signal only when receiving a “Link” at its other port. For
example, the UTP transmits a “Link” only when receiving
a “Link” at the fiber port. [Fig 2(c)].
UTP “10/100” Dip-Switch (10 / 100):
When the “AN/Man” switch is in the “Man” position, the
UTP “10/100” switch selects the speed of the UTP port.
When in the “100” position (factory setting), the UTP port
operates at 100 Mbps. When in the “10” position the UTP
port operates at 10 Mbps.
In “Remote Fault Detection” (RFD), the UTP port transmits
a “Link” signal only when receiving a “Link” at the fiber
port. The fiber port transmits a “Link” only when receiving
“Link” signals both at the fiber port and the UTP port. As
a result, fiber faults (no “Link” received at the fiber) are
looped-back and can be reported to the network’s core [Fig 2(d)].

In “Link Segment” (LS), sometimes referred to as the
“Normal” mode, a port transmits a “Link” signal
independently of any received “Link” at any other port.
For example, the UTP transmits a “Link” regardless of
the fiber receiving a “Link” [Fig 2(b)].
the 10/100 speed and duplex mode of a mating autonegotiating device connected to its UTP port.
In “Link Propagate” (LP), sometimes referred to as
“Link Loss Carry Forward”, a port transmits a “Link”
signal only when receiving a “Link” at its other port. For
example, the UTP transmits a “Link” only when receiving
a “Link” at the fiber port. [Fig 2(c)].
UTP “10/100” Dip-Switch (10 / 100):
When the “AN/Man” switch is in the “Man” position, the
UTP “10/100” switch selects the speed of the UTP port.
When in the “100” position (factory setting), the UTP port
operates at 100 Mbps. When in the “10” position the UTP
port operates at 10 Mbps.
In “Remote Fault Detection” (RFD), the UTP port transmits
a “Link” signal only when receiving a “Link” at the fiber
port. The fiber port transmits a “Link” only when receiving
“Link” signals both at the fiber port and the UTP port. As
a result, fiber faults (no “Link” received at the fiber) are
looped-back and can be reported to the network’s core [Fig 2(d)].

Fiber “FDX/HDX” Full/Half Duplex Dip-Switch:
When in the “FDX” position (factory setting), the fiber port
operates in full-duplex. When in the “HDX” position, the
fiber port operates in half-duplex and its distance is limited
by the IEEE 802.3 standard to 412 meters.
UTP “AN / MAN” Auto/Manual Dip-Switch:
When in “AN” (Auto-Negotiation) position (factory
setting), the converter auto-negotiates and matches
Page 5
When in “Man” (Manual) position, the converter does
not auto-negotiate and operates in the mode selected
by the “FDX/HDX” and “10/100” dip-switches.
UTP “FDX / HDX” Full/Half Duplex Dip-Switch:
When the “AN/Man” switch is in the “Man” position, the
UTP “FDX/HDX” switch selects the duplex mode of the
UTP port. When in the “FDX” position (factory setting),
the UTP port operates in full duplex. When in the “HDX”
position, the UTP port operates in half duplex.
Note that attaching an auto-negotiating UTP port to a
non auto-negotiating (manual / forced / hard-coded)
UTP port may result in 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.
“RJ45 Cross-Over” Switch:
When connecting the UTP to a hub or switch, set switch to
“Straight-Through” (factory setting). When connecting to
a workstation, set to “Cross-Over.”
