NOTE
The LEDs represent only the signal level and not the type of technology (LTE, 3G, ...) used to perform
a connecon.
During the modem boot process, only the rst LED STAT is steady orange. If it remains orange, it means the
modem card was inserted in a wrong slot. This induces a base unit boot error paern on its USR LED as well.
If all signal level LEDs are o, it either means that:
• the modem was not congured;
• the modem conguraon is invalid (including wrong PIN-code);
• there is no signal at all (level 0);
• there is a recepon error (level 99);
4.5. Antenna Diversity
Antenna diversity is a is wireless scheme that uses - at least - 2 antennas to improve the quality and reliability of
a wireless link.
We strongly advise you to use the diversity antenna as it helps the gateway to achieve the maximum network
coverage.
The FLB 3208 - Cellular 4G NA extension card provides 2 SMA connectors: Main and Div.
Front Panel Ewon Flexy Extension Card FLB 3208 - 4G NA (LTE)
IG-0033-00 1.2 en-US Page 7 of 17

•Main
Its purpose is to connect the main antenna. It is always mandatory.
•Div
Its purpose is to connect an oponal second antenna and take advantage of the antenna diversity feature.
If not used, it is recommended to place a cap on the diversity antenna port to avoid premature damage for
future use. By default, there is already one. You will have to remove the cap if you intend to use the diversity
antenna.
Please note that you don't have to acvate or deacvate any sengs: the Div port is always enabled.
NOTE
The second antenna must not be placed in the immediate vicinity of the main antenna.
To improve diversity gain and isolaon and reduce mutual interacons, the two antennas should
be placed at the as far apart as possible, taking into consideraon the available space within the
applicaon.

5. Inseron of an Extension Card
5.1. Slot Compability
The FLB 3208 - Cellular 4G NA extension card must be inserted in one of the B slots of the base unit.
The reference code of the extension cards includes a leer dening their compability:
• FLA xxxx: designate cards that t into A slots.
• FLB xxxx: designate cards that t into B slots.
• FLX xxxx: designate cards that t into any slot.
• FLC xxxx: designate cards that t into any slot of the Ewon Flexy 205.
In addion to the card reference, each type of extension card bears a visual compability symbol on its front
panel:
Table 6. Slot compability for each type of extension card

WARNING
Cards that t only in one slot type have a mechanical mistake-proof security to prevent them from
being inserted in an incorrect slot type.
5.2. SIM Card Inseron
A SIM card obtained from a wireless phone provider is necessary to communicate through the FLB 3208 - Cellular
4G NA extension card.
The SIM card must be inserted before inserng the extension card in the base unit. There is no external access to
the SIM card holder.
The SIM card holder is located on the components side of the extension card.
Proceed as follows to insert the SIM card:
1. Carefully slide the SIM card into the holder, as shown in the picture below.
Note the posion of the cuto (1) of the SIM card.
2. Make sure the card is fully inserted.
If not, it could damage both the drawer and the SIM card when the extension card will be inserted in the
base unit.

1. Remove the slot ller of the locaon where the new card will be inserted. To do so, press on both ends of
the cover. Note that the hooks are o-centered.
Removal of the slot llers
1 Hooks to be pressed are o-centered.
Press while pulling upwards.
2 This metal tag soldered on the PCB acts as mistake-proof security (mang stop in housing).
This mechanism doesn’t apply on the Ewon Flexy 205.
2. Insert the extension card carefully and slide it down unl the hook clicks. Make sure the card is completely
inserted.
DO NOT insist if a resistance is felt when trying to insert the card. This can occur if the extension card is
inserted in a wrong slot type. In such case, check slot compability of the relevant extension card.
3. Boot the unit for the inserted extension cards to be detected.
The web interface of the Flexy base unit has a diagnosc page showing the extension cards in their order of
detecon (from le to right).
WARNING
If an extension card is inadvertently forced in a wrong slot, the base unit will detect the misplaced
card and will not complete its boot process. Therefore, the unit will not be accessible through its LAN
interface. The slot error is returned by the USR LED (red ON 1sec, OFF 0.5 sec).
5.4. Inseron of Mulple Extension Cards
5.4.1. Power Requirements
The internal power converter of the Ewon Flexy base units has been dimensioned to cover a broad range of
dierent combinaons of extension cards.
Inseron of Mulple Extension Cards Ewon Flexy Extension Card FLB 3208 - 4G NA (LTE)
IG-0033-00 1.2 en-US Page 12 of 17

Users should make sure the total power demand of the extension cards does not exceed the capabilies of the
base unit. That is why the noon of Energy Points has been introduced.
The Ewon Flexy - Base Units installaon guide includes a secon giving the Available Energy Points of each type
of base unit.
The power requirements of each extension card is expressed in Energy Demand Points. This number is meant to
check whether the balance with the Available Energy Points of a given base unit with extension cards is OK or
not.
The Energy Demand Points of the FLB 3208 - Cellular 4G NA extension card is 8.
The Ewon Flexy - Base Units installaon guide also includes examples of praccal power balance calculaons.
5.4.2. Soware Compability
The base unit allows the inseron of mulple extension cards, somemes of the same type.
Some conguraons including mulple extension cards, even if mechanically acceptable, are not supported by
the embedded soware. Cards in excess are ignored during the automated detecon process which means that
the base unit and its running extension cards will operate normally.
The Ewon Flexy rmware currently supports up to 1 FLB 3208 - Cellular 4G NA extension card.
The ignored card(s) will appear in the Diagnosc → Status → System Info → System, but they will not be
funconal.
Inseron of Mulple Extension Cards Ewon Flexy Extension Card FLB 3208 - 4G NA (LTE)
IG-0033-00 1.2 en-US Page 13 of 17

Example 1. 2 serial ports vs 2 Ethernet ports
This picture shows an example of a conguraon that would be OK mechanically and power-wise but would not
be supported by the rmware.
During the boot process, the rst 2 serial port extension cards are detected and both can be used.
In the case of 2 single Ethernet cards, these 2 cards are also detected, but the second Ethernet card is not
supported by the rmware and cannot be used.
The presence of this ignored card in the base unit does not alter the operaon of the base unit itself nor does it
alter its accepted extension cards.
5.4.3. Detecon Order
The boot sequence of the base unit includes an automated detecon of the inserted extension cards. This
detecon is done sequenally, slot per slot starng from le to right (when holding the base unit with its logo on
the right side).
