===== How can I obtain the EUI from the serial number of my station? =====


^ Product              ^ EUI                                                       ^ Example            ^ 
|Wirnet Station        |7276FF00<board_type><last 6 characters of the station barcode>         |''7276FF00080E0761''|
|Wirnet iBTS           |7276FF002E<last 6 characters of the CPU module serial number>       |''7276FF002E060337''|
|Wirnet iFemtoCell     |7276FF00<last 8 characters of the CPU serial number> |''7276FF003903046C''| 
|Wirnet iStation       |7076FF00<last 8 characters of the CPU serial number> |''7076FF005403046C''| 
|Wirnet iFemtoCell-evo |7076FF00<last 8 characters of the CPU serial number> |''7076FF006403046C''| 

For Wirnet Station, the **board_type** can be defined like that:

^ board_type       ^value          ^  
| SOP3    | 08  |
| SOP4    | 0B  |

For i-Series products, the 2 first digits of the serial number indicates the region and this region can be defined like that:

^ Product              ^ region       ^value               |  
|Wirnet iBTS           | All regions    | 2E  |
|Wirnet iFemtoCell     | EU-868  \\ US-915 \\ AS-923    | 39 \\ 44 \\ 45 | 
|Wirnet iStation       | EU-868  \\ US-915 \\ AS-923    | 56 \\ 55 \\ 54 |
|Wirnet iFemtoCell-evo | EU-868  \\ US-915 \\ AS-923    | 64 \\ 65 \\ 66 |

You can retrieve the CPU serial number with the following command:
<code bash>
root@klk-wifc-01AAFF:~ # grep serial_number /tmp/sys_startup_status.json 
        "serial_number": "0x4501aaff", 
</code>
Construct the EUI by adding the ''7276FF00'' pattern and add the serial number to obtain''7276FF004501AAFF''. \\
**Care, for Wirnet iStation and Wirnet iFemtoCellEvo, the prefix pattern has changed from ''7276FF00'' to ''7076FF00''.**

To retrieve directly the EUI value, you can retrieve it with the following command:
<code bash>
root@klk-wifc-01AAFF:~ # grep EUI /tmp/sys_startup_status.json 
        "EUI64": "7276FF004501AAFF",

===== How can I put a gateway in two fleets? =====

You cannot. Gateways can only be in one fleet.


===== How can I put an end device in two clusters? =====

You cannot. End device can only be in one cluster.

===== How can I deactivate a user or set an expiration date to a user’s account? =====

You must have at least the role Admin to access to the user profile page you want to manage. But you can only deactivate or set an expiration date to a user who has a lowest role than yours. Of course, you cannot update the limitations of your own account. 

===== What is the maximum number of gateways we can define? =====
We can limit the number of gateways, the number of endpoints and number of users linked to a customer via the administration menu (only accessible for users that have SuperAdmin privileges).

===== What is the maximum number of gateways we can define in the CSV file? =====
There is no limit.

===== When we define a CSV, is it a "add" or a "replacement"? =====
Add

===== What happens when a mote is already defined in the system and when we try to add it again through the CSV file? =====
An exception is raised and the process stops.

===== What happens when the CSV file embodies a syntax error? =====
An exception is raised and the process stops when the error is encountered. All lines located before this point are taken into account by the system.

===== When a mote is removed, is data related to this end-device is also removed? =====
Yes.

===== When a gateway is removed, is data related to all end-devices that are connected to are also removed? =====
No.

===== I have got a frame counter error (FCnt error). What can I do to cancel this status? =====
In the LNS / endpoint menu, click on your endpoint and then click to the cross at the right side of the text "FRAME COUNTER DOWN".
Select F5 for page refresh several times.
=> Status "Uplink ok" appears and uplink message queue is updated with new messages in "Rx messages" tab.

===== What is the VPN subnet address? =====
When connected to the Wanesy Management Center VPN, the IP address assigned to the gateway is in the ''10.8.0.0/16'' subnet.

The gateway LAN subnet should not overlap with this subnet.

===== My external application does not receive any data from WMC =====
WMC does not follow http redirected URLs. You have to input the real URL.

To check whether your URL is redirected or not: ''curl -I https://url-example.com/''

Here is an example of what happens when URL is redirected:

<code>
