I have been working a lot with the Dell N-series over last few years, and now the N2248-ON which can run OS10 as well as the default OS6. We upgraded firmware to the latest 18.104.22.168 and all seemed to go well. Somehow it did not and hosed both primary/secondary firmware. The device was boot looping – the only option was to drop into ONIE Recovery and re-install the firmware. Here are the steps I used:
The ONIE recovery area runs a version of Linux. First check out your NIC to make sure it finds it:
Perfect! My laptop is 192.168.1.99 – and connected directly to the out of band MGMT port.
Next we will TFTP the file up. This file is located in the software archive you download from Dell – Its located in the “Otherfiles” folder. In this case the file name is onie-installer-x86_64-dellemc_n22xx_22.214.171.124. Next I put this on my TFTP server and we can start the install.
First lets turn off the ONIE-Discovery attempts with the onie-stop command.
