FCC and NOM Statements

FEDERAL COMMUNICATIONS COMMISSION AND

INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE 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. Installation

This chapter gives step-by-step instructions for installing the Hardened Ethernet
Extender Switch.

3.1 Selecting a Site for the Hardened Ethernet Extender Switch

As with any electric device, you should place the Hardened Ethernet Extender
Switch where it will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select should meet the
following requirements:

• The ambient temperature should be between -40 to + 167° F (-40 to +75° C).

• The relative humidity should be less than 95 percent, non-condensing.

• Surrounding electrical devices should not exceed the electromagnetic field (RFC)

standards.

• Make sure that the Hardened Ethernet Extender Switch receives adequate

ventilation. Do not block the ventilation holes on each side of the Hardened
Ethernet Extender Switch.

3.2 DIN Rail Mounting

• Connect the DIN rail attachment plate to the back panel of the Hardened

Ethernet Extender Switch.

• Installation: Place the Hardened Ethernet Extender Switch on the DIN rail from

above using the slot. Push the front of the switch toward the mounting surface
until you hear it snap into place.

• Removal: Pull out the lower edge and then remove the Hardened Ethernet

Extender Switch from the DIN rail.

3.3 Connecting to Power

The switch is powered via redundant DC Terminal Block Power Inputs or a 12-VDC
DC Jack.

3.3.1 12-VDC Jack

Step 1: Connect the supplied AC to DC power adapter to the receptacle on the

top side of the Hardened Ethernet Extender Switch.

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.

3.3.2 Redundant DC Terminal Block Power Inputs

There are two pairs of power inputs for use with redundant power sources. You
only need to have one power input connected to run the Hardened Ethernet
Extender Switch.

Step 1: Connect the DC power cord to the pluggable terminal block on the
Hardened Ethernet Extender Switch, and then plug it into a standard DC outlet.

Step 2: Disconnect the power cord if you want to shut down the Hardened

3.3.3 Alarms for Power Failure

Step 1: There are two pins on the terminal block used to detect a power failure.

The output is normally closed when the power source is active. Use this as a dry­contact application to send a signal that detects a power failure.

SPECIAL NOTE: The relay output is in the normally open position when there is no

power to the Hardened Ethernet Extender Switch. Do not connect
any power source to this terminal to prevent shorting your power
supply.

3.3.4 Reset Button

Press the reset button for more than 10 seconds to reset the Hardened Ethernet
Extender Switch back to the default password.

3.4 Connecting to Your Network

3.4.1 Cable Type and Length

Follow the cable specifications listed below when connecting the Hardened
Ethernet Extender Switch to your network. Use appropriate cables that meet your
speed and cablng requirements.

Step 2: Prepare cable with corresponding connectors for each type of port in use.

Step 3: Consult Table 3-2 for cabling requirements based on connectors and

speed.

Step 4: Connect one end of the cable to the Hardened Ethernet Extender Switch
and the other end to a desired device.

Step 5: Once the connections between two end devices are made successfully,
turn on the power and the Hardened Ethernet Extender Switch is ready to
operate.
