A DANTE hold power-cycles a missing Studio B PoE box on its Netgear switch port.
STUDIO-B-SOLO-MON, MON, TB and TB-MON map to ports 0/14-0/17 on the Netgear M4250 Dante switch 10.66.1.102. netgear.py poe_cycle first checks the port's MAC table and refuses if a different device is plugged in there, then runs poe reset. Tested 2026-10-08 13:10 on SOLO-MON: dropped off Dante and was back about 17 s later. install.sh now copies netgear.py too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
