300 Series Industrial Ethernet Switches
The 300 Series Unmanaged Industrial Ethernet Switches support high speed layer 2 switching between ports. All N-TRON 300
Series switches are housed in a ruggedized steel enclosure, and provide Category-5 compliant 10/100-BaseT connections for high
performance network design, and hub/repeater upgrades.
The 302MC/MCE is a 2 port unmanaged media converter that converts 10/100BaseTX copper to 100BaseFX full duplex fiber.
The 304TX, 306TX, and 308TX are affordable and share a small footprint. Each switch is capable of auto negotiating 10/100 Mb
and half/full duplex communications.
The 305FX and 306FX2 switches are unmanaged and have 4 ports similar to the 304TX, plus an additional multimode fiber optic
up-link port(s), capable of 2 Kilometers of 100 Mb communications without the use of repeaters.
The 305FXE and 306FXE2 switches are unmanaged and similar to the 305FX and 306FX2, respectively. However, these models
use singlemode transceivers with extended range capability. The N-TRON FXE products utilize singlemode fiber transceiver(s)
that are capable of 15, 40, and up to 80 Kilometers of 100 Mb full duplex communications.
All fiber products utilize the IEEE compliant SC or ST duplex connectors for fiber optic communications. All 10/100Base-TX
ports utilize the RJ45 shielded connectors.
Key Features
•Full IEEE 802.3 & 100Base-FX Compliance
•Extended Environmental Specifications
•Support for Full/Half Duplex Operation
•LED Link/Activity Status Indication
•Autonegotiation, Autosensing Speed, Duplex, and Flow Control
•Up to 1.0 Gb/s Maximum Throughput
•Industry Standard 35mm DIN-Rail Mounted Enclosure

PACKAGE CONTENTS
Please make sure the Ethernet Switch package contains the following items:
1. 300 Series Unit
2. N-Tron Product CD
Contact your carrier if any items are damaged.
INSTALLATION
Read the following warning before beginning the installation:
WARNING
FXE units contain a class 1 laser. Do not stare into the laser beam (fiber optic connector) when installing or operating the
product.
Never install or work on electrical equipment or cabling during periods of lightning activity.
Disconnect the power cable before removing the enclosure top.
Do not operate the unit with the top cover removed
UNPACKING
Remove all the equipment from the packaging, and store the packaging in a safe place. File any damage claims with the carrier.

DIN-Rail Mounting
Install the unit in a standard DIN-Rail. Recess the unit to allow at least 5” of horizontal clearance for fiber optic cable bend radius
(2” for TX models).
To install the unit to 35mm industrial DIN-Rail, place
the top edge of the included mounting bracket on the back
of the unit against the DIN-Rail at a 15° angle as shown.
Rotate the bottom of the unit to the back (away from you)
until it snaps into place.
To remove the unit from the 35mm industrial DIN-Rail,
place a flat head screwdriver into the orange release clip
found at the bottom of the unit, and apply downward force
on the clip until it disengages from the bottom of the unit
from the DIN-Rail. Rotate the bottom of the unit towards
you and up at an approximate 15° upward angle to
completely remove the unit.
300-PM 900-PM
900-RM
With the exception of the 524TX and
526FX2, all N-Tron™ products are designed
to be mounted on industry standard 35mm
DIN-Rail. However, DIN-Rail mounting may
not be suitable for all applications. We offer
three alternative mounting solutions: Our 300
Panel Mount Assembly (P/N: 300-PM) may
be used to mount a single 300 Series unit to a
panel or other flat surface. Our 900 Panel
Mount Assembly (P/N: 900-PM) may be
used to securely mount our 100, 200, 300,
400, 500, or 900 Series products to a panel or
other flat surface; Our Rack Mount Assembly
(P/N: 900-RM) may be used to mount our
products to standard 19" racks.

APPLYING POWER (Top View)
Unscrew & Remove the DC Voltage Input Plug from the top header.
Install the DC Power Cables into the Plug (observing polarity on unit).
Plug the Voltage Input Plug back into the top header.
All LED’s will flash ON Momentarily
Verify the Power LED stays ON (GREEN).
Note: Either V1 or V2 can be connected to power for minimal operation. For redundant power operation, V
1
and V
2
plugs
must be connected to separate DC Voltage sources. Use wire sizes of 16-28 gauge. The power cord should be limited to less
than 10 meters in order to ensure optimum performance.
Recommended 24V DC Power Supplies, similar to
100VAC/240VAC:
N-Tron’s NTPS-24-1.3, DC 24V/1.3A,
Operating temp range -10°C to +60°C
CONNECTING THE UNIT
For 300 Series fiber units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables. For Fiber
Optic ports, the TX port on the near station should be connected to the RX port of the far end station, and the RX port should
be connected to the TX port of the far end station.
For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the RJ45 connector. For 100Base-T ports, plug a
Category 5 (or greater) twisted pair cable into the RJ45 connector. Connect the other end to the far end station. Verify that
the LNK LED’s are ON once the connection has been completed. To connect any other port to another Switch or Repeater,
use a standard Cat5 straight through or crossover cable.
