Data Sheet
© PHOENIX CONTACT 2011-06-30
1Description
The FL SWITCH SFNT… range of Factory Line switches
can be used for quick and cost-effective Ethernet network
expansion to the field level. These unmanaged switches
allow operation across a wider temperature range than most
switches, allowing networks to expand into process industry
environments, such as oil/gas, chemical, water/wastewater,
wind energy, security, monitoring and some marine
segments. Due to the narrow housing design, the switches
are suitable for use in control cabinets and junction boxes.
The FL SWITCH SFNT… switches support the auto
negotiation function on the RJ45 ports and offer
transmission speeds of 10/100 Mbps. Mixed operation for
the connection of segments with different data transmission
speeds is also supported. The RJ45 ports offer an auto
crossing function, which means it is not necessary to make
a distinction between 1:1 and crossover cables. Unused
RJ45 ports can be fitted with security caps to provide
mechanical protection against unauthorized use.
Fiber optic ports are available in an SC or ST format and
offer speeds of 100 Mbps. The fiber optic ports extend the
segment length to 2000 m or more, depending on the quality
of the fiber optic cable.
2 Features and Benefits
-40 to 75°C operating range
Pretagged high priority messages are forwarded before
lower priority messages during periods of high network
traffic
Auto-negotiation and autocross simplify cabling
Couple copper network segments with different bit rates
with automatic detection of the data transmission speed
of 10 or 100 Mbps
Individual LEDs at each port indicate communication
activity and data rate
Redundant power supply capable with local (LED) and
remote (dry contact) alarms to indicate failure of one or
both power supplies
Switch-selectable link diagnostics indicate
disconnected ports via local and remote alarms
Available fiber optic options for extended distance and
electrical noise immunity
Fiber optic ports available in SC or ST formats
Low-cost, low-complexity security by connecting
Layer 1 security elements at the RJ45 ports to restrict
access and tampering (optional)
Please note the different connection directions of the transmission media for five-port switches: copper cables are
connected at the front, glass fiber cables at the bottom.

6 Installation
Install the FL SWITCH SFNT… on a clean NS 35 rail. To
avoid contact resistance use only clean, corrosion-free rails
that meet the EN 60715 standard. End clamps can be
mounted on both sides of the module to stop the modules
from slipping on the rail.
6.1 Assembly
1. Place the module onto the rail from above. The upper
holding keyway must be hooked onto the top edge of
the rail.
2. Push the module from the front towards the mounting
surface.
3. Once the module has been snapped on properly, check
that it is fixed securely on the rail.

authorized to start up, ground and mark devices,
systems, and equipment according to the
standards of safety technology.
NOTE:
The FL SWITCH SFNT… module is designed for
SELV and PELV operation according to
IEC 61140/EN 61140.
NOTE:
Connect the mounting rail to protective earth
ground using a grounding terminal block. The
modules are grounded when they are snapped
onto the rail. Connect protective earth ground
with low impedance.

6.2 Removal
1. Insert a suitable tool (e.g., needle-nose pliers) into the
arresting latch and pull it down.
2. Pull the module slightly away from the mounting
surface.
3. Lift the module from the rail.
6.3 Mounting Plate
The FL PA SFNT 5-8 mounting plate provides a method for
mounting SFNT 5- and 8-port switches to a flat surface in
any orientation. The plate can be mounted on either side of
the switch to allow the network ports to face the proper
direction.
FL DA SFNT 5-8 adapter allows installation of the switch on
a DIN rail with a low profile. The adapter also installs on
either side of the switch.
Figure 2 FL PA SFNT 5-8 Mounting Plate
6.4 Power Connection
The switch is designed for SELV and PELV operation at
+24 V DC according to IEC 61140/EN 61140. Only SELV
and PELV according to the defined standards may be used
for supply purposes.
Snapping the switch onto a grounded rail connects it to the
ground potential. In an environment particularly prone to
EMI, noise immunity can be increased by an additional low-
impedance connection to protective earth (see Figure 3).

supply

The dimensions of the FL PA SFNT 5-8 are
shown in Figure 10.

2665_en_I PHOENIX CONTACT 8
Use power conductors between 0.2 - 2.5 mm²
(24 - 12 AWG). Torque connection screws to 0.5 - 0.6 Nm
(5 - 7 lb-in.).
6.5 Alarm Contact
The FL SWITCH SFNT switch provides contacts (R1, R2)
for remote alarms if a failure is detected. Alarms are
triggered if one or both power supplies fail. An alarm can be
triggered if a port fails. Individual port alarms can be enabled
via a DIP switch located on the bottom of the switch.
The alarm relay is a normally closed type. When there are
no faults, the contact is held open. When a fault occurs, the
relay is de-energized to close the contact.
The FL SWITCH SFNT 5... and FL SWITCH SFNT 4... use
a five-position DIP switch. The FL SWITCH SFNT 8..., FL
SWITCH SFNT 7... and FL SWITCH SFNT 6... use an eight-
position DIP switch. Each DIP switch position corresponds
to the port number.
To enable an alarm, move the appropriate slider to the ON
position.
To disable an alarm, move the appropriate slider to the off
position.
6.6 Ethernet Interface
The FL SWITCH SFNT has five Ethernet ports on the front
in RJ45 format to which only twisted-pair cables with an
impedance of 100 Ω can be connected. The data
transmission speed is 10/100 Mbps. In addition, every port
has an auto crossing function: it is not necessary to make a
distinction between 1:1 or crossover Ethernet cables.
Figure 5 RJ45 pin assignment
6.7 Fiber Optic Connection
Two different types of fiber optic connection are available.
The fiber optic connector(s) are located on the lower front
face of the 8-port models or on the bottom face of the 5-port
models.
The ST connectors are typically individual round connectors
and use a 1/4-turn connection.
The SC connectors have a square interface and the
“conductors” are typically locked together through the
connector.
Figure 6 5-port fiber optic ports (SC connectors)
Figure 7 8-Port ST fiber optic ports
Figure 8 8-port SC fiber optic ports
In addition to the remote alarm, failure is also
indicated by the alarm LED On.
Failure indication of a fiber optic port can be in
either the RX or TX fiber.

7 Switching Characteristics
Store and Forward
All data telegrams received by the switch are saved and
their validity checked. Invalid or faulty data packets
(> 1522 bytes or CRC errors) and fragments (< 64 bytes)
are rejected. Valid data telegrams are forwarded by the
switch. The switch always forwards the data using the data
transmission speed that is used in the destination network
segment.
Multi-Address Function
The switch independently learns the addresses for
termination devices, which are connected via a port, by
evaluating the source addresses in the data telegrams. Only
packets with unknown addresses, with a source address of
this port or with a multicast/broadcast address in the
destination address field are forwarded via the
corresponding port. The switch can store addresses in its
address table with an aging time of 5 minutes. This is
important when more than one termination device is
connected to one or more ports. In this way, several
independent subnetworks can be connected to one switch.
Quality of Service (QoS): IEEE 802.1P/Q
The FL SWITCH SFNT… switches are capable of reading
Ethernet packets that have already been assigned a priority
level by a managed switch. In cases of heavy traffic, packets
with a priority level between 4 and 7 are considered high
priority and processed before packets with a priority level
between 0 and 3. After prioritization the packets are
forwarded without modification.
