QUICK SUMMARY: PSL Beckhoff is down, but apparently the laser is still running? Possibly just a readback issue (PSL overview attached). All CDS cameras appear to be down (blue screen), including PSL enclosure cameras. Will talk to Dave/Patrick about this.
Several Tuesday maintenance activities planned for today, including a Guardian machine reboot, DAQ restart, and some craning in the LVEA.
ISC_LOCK was in 'GREEN_ARMS_MANUAL' with ALS Y locked and offloaded. I took ISC_LOCK to 'DOWN' and SEI_ENV to 'MAINTENANCE' in prep for the Guardian reboot this morning.
Cameras and PSL Beckhoff all went dead at the same time last night, 23:47 PDT. Richard confirms the network switch in the CER is dead, which explains why the PSL Beckhoff machine is still running fine even though channels can't be read.
