Hardware Reset
The web UI of a Salia charging station has no default passwords. The passwords for the accounts root, user and service are set at the first start of the web UI by whoever commissions the station, and the web UI offers no way to recover them. If the passwords are lost, the station is reset with the rotary switch on the controller board. The reset does not need a network connection, a password or a support login, but it needs access to the inside of the housing.
Available in firmware 2.3.78 and later. Stations on firmware 2.2.x have neither the password setup nor this reset; on older 2.3.x versions the password reset goes through eCharge support.
What the reset does
| Reset | Kept | |
|---|---|---|
| Passwords | user and service are deleted. The first-setup page asks for new passwords for all three accounts, including root. | |
| RFID cards | The list of taught-in cards is emptied. | |
| OCPP | OCPP is disabled; the backend URL (including the charge point ID it contains), user name and password are cleared. | |
| Network | IP settings, DHCP, DNS, time server. The station keeps its address. | |
| Charging configuration | Current limits, meters, solar settings, phase switching and every other setting on the configuration page. | |
| Charging log | Recorded charging sessions. |
The reset is meant to regain access, not to return the station to the factory state. After the reset the OCPP settings and the RFID cards have to be entered again.
The rotary switch
The switch sits on the Salia controller board inside the housing. It is a
16-position rotary switch marked 0 to F. Its normal position sets the
phase count and current limit of the station and was chosen by the installer;
position F is reserved for the reset.
Note the current position before turning the switch. Take a photo. The position encodes the current limit and the phase count. A switch that is returned to a wrong position changes the maximum charging current of the station.
Opening the housing exposes mains voltage. Switch off the circuit breaker of the station before opening it. The work is to be done by a qualified electrician.
Procedure
- Switch off the circuit breaker of the charging station and open the housing.
- Note or photograph the position of the rotary switch.
- Turn the rotary switch to position F.
- Switch the circuit breaker on again. The station boots (green LED on, red LED blinking) and, once booting has finished, switches itself off: all LEDs go dark. The reset has been carried out at this point.
- Switch the circuit breaker off.
- Turn the rotary switch back to the position noted in step 2.
- Close the housing and switch the circuit breaker on. The station boots normally.
- Open the web UI of the station in the browser. It shows the first-setup page and asks for new passwords for root, user and service.
The check for position F runs at every start. A station left on F
resets and switches itself off at every start, so step 6 is not optional.
After the reset
Setting the passwords. Set the passwords right away: until the setup is completed, anyone in the local network can open the setup page without signing in. Each password needs at least 12 characters with at least one upper-case letter, one lower-case letter and one digit. Only the letters A–Z and a–z and the digits 0–9 are accepted; special characters and umlauts are rejected. After Apply changes the station saves the passwords and restarts its web server, which can take up to a minute; the web UI is then reachable with the new passwords. Store them: there is no other way back than this reset.
Browser cache. The web UI uses HTTP basic authentication, and browsers keep those credentials as long as they run. If the browser still shows a sign-in prompt after the reset or refuses the new passwords, clear the browser cache and close all windows of the browser before opening the web UI again.
OCPP and RFID. Enter the backend URL and the OCPP credentials again under Configuration and enable OCPP; teach in the RFID cards again. The rest of the configuration is unchanged.
What the reset does not fix
The reset only removes access data. It does not change the charging configuration and does not clear a fault the station reports, for example a Faulted connector status in an OCPP backend. Such faults have a hardware or configuration cause and are handled separately.
