Your Alcatel-Lucent 9926 BBUv2 eNodeB Wants an Update
So you pull out your 9926 BBUv2, boot it up, and remember it’s only running LR16.1.L MNCL3. That’s so 2018. You really want to run mid-2019’s MNCL4 drop instead. It’s newer. Fresher. Nicer. There’s only one way to fix this… Run NEM You’ve got the latest Network Element Manager (NEM) installed on your Linux machine.…
