C.1 Sending an OS via USB
Follow these steps to send the new OS to the NL241 via USB:
1. Plug the wall charger into an AC outlet and the barrel connector into the NL241 power
jack.
2. Connect a USB cable between one of your computer USB ports and the USB port on the
NL241.
3. Open
Device Configuration Utility
.
4. Under Device Type, select Network Peripheral > NL241.
5. Select the appropriate Communication Port.
6. Go to the Send OS tab.
7. Click Start.
8. In the resulting dialog box, select the file that should be sent to the device as an operating
system (this file should have an .obj extension) and click OK.
9. The operating system will be sent to the NL241.
10. After the file has been sent, the LED on the NL241 will flash repeatedly while the NL241
copies the OS into its internal flash. Depending upon the operating system that was
previously installed, it may take up to 2 minutes for the NL241 to finish updating the
operating system. While the LED is flashing, the NL241 is in a vulnerable state where a
removal of power could leave the NL241 without a valid operating system to run. Do not
remove power until the LED stops flashing.
