### **Examples**

Update the firmware on all modules in the system to the image in sourcefile.pkg on the next power cycle.

```
$ sudo ipmctl load -source sourcefile.pkg -dimm
```

Check the firmware image in sourcefile.pkg and retrieve the version.

```
$ sudo ipmctl load -examine -source sourcefile.pkg -dimm
```

> NOTE: Once a firmware image is staged for execution, a power cycle is required before another firmware image of the same type (production or debug) can be staged for execution using this command.
