To get the TV-VAVB3-E2's serial number
If you need the controller’s serial number when troubleshooting, the number is on:
• A Module Status report (Modstat) under Core (or Main) board hardware
• A QR code, serial number, and MAC address printed on a sticker on the cover
• A laser-etched number and QR code on the inside circuit board.
See To get a Module Status report (page 101).
