Power cycle h1seib2 system

Jim, Jonathan, EJ, Oli, Fil, Dave:

h1seib2 has had several problems over the past 24 hours; missing BIO adnaco, overheating Mellanox IPC, user model ADC timeout, ISI L4C switching not working, DAQ CRCs.

We decided a clean power cycle of the front end and IO Chassis is a good first step.

09:07 h1seib2 stop all models and powerdown. Fil went into CER and powered down IO Chassis and AI Chassis

09:09 IO Chassis power up, CPU power up, AI chassis power up.

Once the models got going again, Jim reported the binary switching problem was resolved.
