Inadvertently reformatted N2048P
I was trying to reset an N2048P to factory defaults and inadvertently selected the option to reformat the filesystem instead.
Now the switch boots only to a u-boot menu. I tried to reload the firmware via TFTP, but I get an Error: Ethernet external port not connected.
How can I recover this switch?

Within the Uboot window we have some commands available to us. Using these commands along with the boot menu we can transfer the bootcode to the switch. Both of these options can take some time to finish transferring, but the first option will be quicker than using the console method. Some of these steps can change slightly based on the software you are using.
Process for transferring the bootcode using the OOB interface:
You selected to update Back-Up Image image1...
Process for transferring the bootcode using the console interface:
u-boot> setenv baudrate 115200
u-boot> loady
Current Active Image: image2
You selected to update Active Image image2...

Thank you so much for your help, the console interface instructions worked fine and I now have an operational switch again!

The switch has two images, these are the locations where the firmware is installed. One image is active at a time, with the other image being a backup image. The stk file is what is copied to these images. When you performed these steps did you run across any error messages? did the file transfer complete successfully?
