Statements
This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict
accordance with the manufacturer’s instructions, may cause inter ference to radio communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis sion from digital apparatus set out in the Radio
Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de
la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

3. Configuration
3.1 One-Channel Hardened Ethernet Extender
3.1.1 DIP Switch
Ports
The Hardened Ethernet Extender provides TX ports and one Ethernet Extender port. For the TX ports, it uses RJ-45 connectors
and autosenses 10-/100-Mbps speeds. For the Ethernet Extender port, it uses RJ-11 and terminal block connectors and
autosenses 1-/3-/5-/10-/15-/20-/25-/30-/40-/50-Mbps speeds.
Ethernet Extender Mode Settings
Ethernet Extender mode settings are simple via a DIP (Dual Inline Package) switch on the top panel of the Hardened Ethernet
Extender.
DIP Switch
There is one pin on the DIP switch for Ethernet Extender mode settings. Refer to Table 3-1 for more details.

As with any electric device, you should place the equipment where it will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select should meet the following requirements:
• The surrounding air temperature should be between -40 to +167° F (-40 to +75° C).
• The relative humidity should be less than 95 percent, noncondensing.
• Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards.
• Make sure that the equipment receives adequate ventilation. Do not block the ventilation holes of the equipment.
• The power outlet should be within 6 feet (1.8 meters) of the product.

4.3 DIN Rail Mounting
• Attach the DIN rail plate to the back panel of the Hardened Ethernet Extender.
• Installation: Place the Hardened Ethernet Extender on the DIN rail from above using the slot. Push the front of the Hardened
Ethernet Extender toward the mounting surface until it audibly snaps into place.
• Removal: Pull out the lower edge and then remove the Hardened Ethernet Extender from the DIN rail.

4.4 Connecting to Power
Redundant DC terminal block power inputs or 48 VDC DC jack:
4.4.1 Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs that you can use to power up this device. You only need to have one power input connected
to run the Hardened Ethernet Extender.

Chapter 4: Installation
Step 1: Connect the DC power cord to the pluggable terminal block on the Hardened Ethernet Extender, and then plug it into a
standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the Hardened Ethernet Extender.
4.4.2 48-VDC DC Jack
Step 1: Connect the supplied AC to DC power adapter to the receptacle on the top side of the Hardened Ethernet Extender.
Step 2: Connect the power cord to the AC to DC power adapter and attach the plug into a standard AC outlet with the
appropriate AC voltage.
