6 Installation of Wirnet iFemtoCell
6.1 Mounting of the enclosure
The Wirnet iFemtoCell enclosure must be mounted on any concrete pedestal,
concrete wall or any non-flammable surface (UL94-V0).
It must not be mounted on a flammable surface.
The Wirnet iFemtoCell may be mounted on a wall using the two oblong holes.
Only two screws (not included) are needed, all mounting informations are mentioned on the following drawing:
6.2 Setting connections
Before setting all connections, ensure that the power supply is not connected to the
mains supply.
When the Wirnet iFemtoCell is installed, three configurations are possible regarding the technology used to access Internet:
Ethernet connection, requiring an Ethernet access through a dedicated RJ45 cable
Wi-Fi connection, requiring a Wi-Fi access point
3G/4G connection via USB dongle (optional) and an USIM subscription (not included)
The three configurations may be used in parallel. A typical example is the possibility to insure Ethernet backup by a 3G/4G link.
The required connections needed to operate the Wirnet iFemtoCell are listed below (see chapter 4 “Overview” for details of connectors):
Power supply
Ethernet cable (not included)
LoRa antenna
USB mass-storage key (not included)
3G/4G USB dongle (optional) and an USIM subscription (not included)
The Ethernet cable is not provided and must consist of two RJ45 T 568A (or 568B) plugs on each side.
KERLINK recommends using a cable with the following characteristics:
• Category: 6A
• Shielding: STP (U/FTP) or SSTP (S/FTP)
• Section conductors: AWG26
• External jacket: LSZH or PUR
• Maximum length: 100 meters
• Operating temperature range:-20°C to +55°C
In case of 3G/4G connection with USB dongle:
• KERLINK recommends using a validated USB dongle (contact your reseller to have the list of validated USB dongles).
Alternative dongle may require additional drivers and firmware update to be used.
• To optimize the radio performances, when possible, KERLINK strongly recommends dissociating the 3G/4G USB dongle
away from the enclosure and the LoRa antenna by using a 1 meter extension cable.

6.3 Power ON
Once the LoRa RF antenna, the Ethernet cable (if used) or the optional 3G/4G USB dongle (with USIM card inserted) and the power supply jack
connector are connected, the Wirnet iFemtoCell can be powered ON by connecting the power supply onto the 230VAC mains supply.
The power supply is provided with E/F type cable (Europe) or B type cable (USA).
6.4 First connection
When the Wirnet iFemtoCell is installed, the first connection can be done by two different ways:
Using Wi-Fi connection:
o Press the WPS button (Wi-Fi Protected Setup) on the Wirnet iFemtoCell (see chapter 4 “Overview”) then press the WPS button on the Wi-Fi
access point of the installation
o The connection will be established automatically
Using Ethernet connection:
o Plug the Wirnet iFemtoCell to your box or internet router with an Ethernet cable
o The connection will be established automatically
6.5 Functional check
To ensure the Wirnet iFemtoCell is started up, check the behavior of the LED indicators:
LED
Specification
LED 1: Power RED blinking during the kernel boot
GREEN blinking during system boot
GREEN when boot is finished
LED 2: Backhaul RED during boot
If the applicative software provided by KERLINK is installed:
• RED if applicative software is disconnected
• GREEN blinking during applicative software connection
• GREEN fix if applicative software is connected
LED 3: LoRa traffic RED during boot
If the applicative software provided by KERLINK is installed:
• Applicative software management
• Rx: GREEN blinking
• Tx: RED blinking
Applicative software stands for embedded software running on the Wirnet iFemtoCell like KERLINK Small Private Network
or another Packet Forwarder (software that forwards RF packets received to a server and emits RF packets that are sent by
the server).
Please contact your reseller to know the LEDs behavior if the applicative software installed on the Wirnet iFemtoCell is not
the one officially provided by KERLINK.
6.6 Configuration
Once the connection is established (Ethernet or Wi-Fi), a Web configuration interface is accessible from the Wirnet iFemtoCell.
This Web interface is accessible on any IP address that has been allocated by the network.
You first have to get the IP address that has been allocated to the Wirnet iFemtoCell
by DHCP on either Ethernet or Wi-Fi and then point your Web browser to it. You
can find this information from your Wi-Fi/Ethernet router on its administration
interface.
For example:
http://192.168.1.13/
The login credentials are “admin” for user and “admin” for password.
