[evla-sw-discuss] EVLA power outage

[Matt Gardiner]

General status update:

Widar is close to being ready for script tests, Ken is working on this 
at the AOC.  Kerry is working with Eric on the deformatters.  Ant 24 IF 
B deformatter is not receiving the timecode from the L305, it looks like 
IF B will be out through the weekend.  MCCC and CBE are okay (Kevin, 
James and Martin sorted these out).

Generators - are operational again.  We're on SEC power and if we have 
another outage the generators should start.  Several issues were fixed: 
the local 100+ gallon day tanks failed to refuel automatically and ran 
dry last night, and the 125 Battery bank had loose wires.  In the course 
of their work we briefly lost utility power twice mid-afternoon and blew 
a TVS on the Widar 48V supply.  Kerry bypassed the affected rectifier 
with Bob's instructions.  (Richard Murillo, Lew Serna, and Matt Metevier 
worked on fixing this; Bob Broilo, Jaime, Shawn Hughes are out of town.)

LO/IF - Systems are in good shape.  Rob has fixed the L350 and other 
issues in the CER and has re-synced the antennas.  Antenna 15 lost 
network communication in the second power outage but Rob got it talking. 
  He's just fixed a couple individual LO module problems (antennas 4, 
20, 23).

API - RMS Phase is not available although the emr1-m353_api is talking.

Cryo systems are mostly okay now except for 13 X, the remaining 
receivers are cooling.  Ant 12 F317-1 is not talking.  (Rudy Latasa, Jim 
Gregg, Frank B.)

Servo systems were taken care of this morning. (Dave Parker)

Rich fixed the monitor data loader software early this morning.

Cheers,
Matt
