Starting, Stopping, and Restarting IRIS Software

IRIS starts automatically on boot-up. If necessary, you can start, stop, or restart IRIS manually using the following commands

Check that power is applied to the radar and all IRIS devices.

CAUTION

When IRIS starts up, it tries to execute default operating tasks.

If there is a danger to personnel from radiation, set your radar console switch in the Local position so that IRIS cannot take control.

You can also configure a mode named DEFAULT that does not start the radar antenna and transmitter. See Running Radar from the Radar Status Menu.

Login as radarop.
To start IRIS manually, in the operating system prompt, type:
```
sudo service iris start 
```
The IRIS startup process starts.
To stop IRIS manually, in the operating system prompt, type:
```
sudo service iris stop
```
To restart IRIS manually, in the operating system prompt, type:
```
sudo service iris restart
```

When start-up is complete, the operating system prompt reappears, and IRIS is ready to use.

If you have trouble with your system, run:

sudo journalctl -u iris.service
