Since the blower in the rack containing the BSYBD Shunt Chassis was found to have broken shock mounts, I will check all shunt racks throughout the accelerator to ensure no other blower supports are broken. If broken ones are discovered, they will be replaced and the work will be noted in this ATLis.
Removed the shunt chassis. Disconnected shunt cables, shorted them together, insulated with electrical tape and secured out of the way. Secured all communications and interlock wiring associated with the chassis. While removing the shunt chassis we discovered that three of the four shock mounts holding the blower had failed. They will need to be replaced. Installed a metal plate to temporarily support the blower.

Do you have cable pulls that still need to be done from the
Injector Service Building, Bldg53, down into the tunnel?
If yes, please shoot me a message (moser@jlab.org) by
Wednesday 3/3, close of business.

Looking to refill them at an opportune time.
Thanks.
My mistake Beam Sync is up and running what is down is 30hz because some of the Injector SEE bpm IOC vme crates are down which is interrupting the 30hz daisy chain around the machine. So beam sync is ok but 30hz is not while the Power Outage in the Injector continues. I did perform a soft reboot to all 4ch bpm IOCs in the East Arc.
