4. verify that the NI2400 is not in Timed mode. In this case, once ended the timeout time
configured in webpage "Energy management", the network card turns off if there isn't
any data exchange.
E-MAIL SENDING
ARE YOU UP TO DATE?
1. Verify that you installed the last version of firmware
2. Verify that you have the correct power supply (from photovoltaic module or external
power supply) on the V IN clamp of the NI2400
This paragraph provides NI2400 e-mail sending troubleshooting tips.
THE E-MAIL TRANSMISSION INVOLVES DIFFERENT DEVICES. IN THIS DOCUMENT, WE
TRY TO DETERMINE WHICH DEVICE COULD CAUSE THE PROBLEM AND THEN WE TRY
TO SOLVE IT.
The "system" is composed as follows:
1. NI2400
2. Internet Service Provider (ISP): allows the communication between NI2400 and the e-
mail server
3. E-mail Server (ESP): allows to send and to receive e-mails
NOTE: it may be that the ISP (Telecom, Vodafone, AT&T, Verizon, etc.) doesn't
coincide with the ESP (Gmail, AOL, etc.)
Resolution
FIRST OF ALL, INSURE WITH YOUR IPSP THAT:
1. The SIM card or your network is enabled to the internet
2. The e-mail transmission is allowed on the used APN or on the used network
SECONDLY, INSURE WITH YOUR ESP THAT:
1. there are no momentary breakdowns on ESP server
2. the username and password of your e-mail account are valid and accepted
3. that the e-mail account you want to use is active

THESE POINTS DO NOT DEPEND ON NEXT INDUSTRIES AND NEED TO BE RESOLVED
THROUGH YOUR ISP OR ESP.
If you don't have any problem with the ISP and the ESP, you could proceed looking for
causes on the NI2400.
IF THE NI2400 DOESN'T SEND ANY E-MAIL ALTHOUGH IT IS CONFIGURED.
Follow this step, testing after each:
1. verify the events log and refer to manual "Codes Alarms-Events" to understand eventual
logs
2. verify that the SIM is properly inserted in its slot into the communication device (HSPA
router or 2G modem) or that your network devices are properly configured to permit the
e-mail sending (firewall, port, etc)
3. verify that you inserted your SMTP server account correctly ("SMTP Server Configura-
tion" page)
4. verify that the SMTP account is a simple authentication. The NI2400 doesn't support SSL.
5. If you use a communication device base on mobile network, verify that there is a mobile
coverage (according to the adopted technology e.g: 2G, 3G or 4G) on the site where the
NI2400 is installed.
6. If you use a 2G (GSM/GPRS) modem, verify that there is a good 2G signal where the
NI2400 is installed. In some place there is only a 3G or 4G coverage. 2G modem is not
compatible with 3G, 4G and CDMA networks.
