Power outage in C-room

All MRO instruments

The 23rd May correlator room outage was triggered by a release of fire suppression gas.  The gas release triggered a power shutdown.  The sudden loss of load on the power generation facility resulted in the power generation facility shutting down for approximately one second.  The power generation facility came back online via diesel generators.


CIRA operations staff have not identified any damage to equipment or instruments as a result of the rapid power cycle. 


However, all equipment in the correlator room within the Curtin racks is not protected by a gaseous fire suppression system in the event of an actual fire. Therefore, as a safety measure ALL  equipment and instruments within the correlator room will be powered down by 1600h WST 29 April.  It is expected that all equipment will remain offline to at least the 10 May. 

UPDATE

MWA correlator will remain offline pending the outcome of the causes of equipment failure.  All other instruments and equipment can continue to operate as normal

MRO site wide power outageAll MWA, SKA and external instrumentsUnknown

Update 22 Dec 2020

The source of the power outage was a blown EM filter on a LV supply that provided power to the correlator room.  The correlator room lost power and some HV breakers tripped across the site.  Fortunately, the Curtin site area did not lose power.  Only equipment within the Curtin racks of the correlator room lost power.

All MWA, external instruments, AAVS and EDA2 field equipment did not lose power and a quick remote check has identified no obvious damage.  It is recommended all instrument managers check their field instruments and advise of any concerns to operations@lists.mwatelescope.org

Correlator room equipment and machines are now being brought online.  Should anyone have any concerns or issues with their equipment in the correlator room please email operations@lists.mwatelescope.org.

There will be no further updates regarding this power outage.

Update 21 Dec 2020

As at Australian WST1100h 21 Dec 2020, power was lost to all instruments, telescopes and equipment at the MRO.  On site CSIRO staff were unable to identify the cause of the fault.  Tomorrow 22 Dec 2020, electrical contractors and other CSIRO staff will travel to the MRO to support the repair effort.

Next update: WST 1800h 22 Dec 2020.

Loss of power in correlator roomAll MWA, SKA and external instruments and equipment within the MRO correlator room

Unknown - under investigation

The MRO Correlator room will remain without power for an unknown period of time.  The cause and significance of the power outage remains under investigation.

The next information update will occur before COB Wed 29th July. 

Should you have any questions or concerns, please contact operations@lists.mwatelescope.org.

Please do not contact CSIRO / MRO staff directly.  The staff members are very busy and are cognisant of the implications of the power outage.

UPDATE: 30 Jul 2020

The power outage in the correlator room was caused by the activation of fire suppression systems.  The fire suppression was activated 23 July in response to a small component failure on a PCB that emitted particulate and smoke into the correlator room environment.  The cause for the activation of the fire systems has been investigated and identified. 

CSIRO are currently focussed on reinstalling and re-certifying all the components necessary to bring the fire suppression systems back online.  Power was quickly restored to the c-room but without fire control systems, equipment and instruments cannot be returned to operational status.

CSIRO have advised this process is likely to be complete by the 14th August. 

UPDATE: 14 Aug 2020

CSIRO have advised that works continue on recertifying the correlator room fire suppression systems but it is unlikely that instruments and equipment will be back online 17 Aug 2020.  The next update will be provided 21 Aug 2020 unless further information from CSIRO is provided in the interim.  CSIRO are aware of the impact this is having on all MRO users and are working with contractors to bring the MRO back online as quickly as possible.

UPDATE: 25 Aug 2020

CSIRO have advised that the fire suppression systems are being repaired.  However, during the repairs one of the gas canisters containing fire suppression gasses activated.  This has prevented the correlator room returning to operational status.  CSIRO are currently conducting a risk assessment to determine the level of risk associated with a reduced capacity to suppress a fire in the correlator room.  The outcome of this risk assessment will determine when and if the correlator room is returned to operational status this week.

UPDATE: 26 Aug 2020

CSIRO have advised they are willing to accept the reduced fire suppression system risk. The equipment in the correlator room is in the process of being brought online.

9-10 July 202015 July 2020Unscheduled correlator room outageAll MWA, SKA and external instruments and equipment within the MRO correlator roomCooling system failure

Cooling systems failures in the MRO Correlator room continued overnight.  Automated shutdowns of equipment and instruments also occurred.

Cooling has been re-established to racks and equipment.  Equipment and instruments can be brought back online.

The source of the fault is known, the cause of the fault remains unknown.  Updates will be distributed as information becomes available.

UPDATE PM 10 Jul 2020

The cooling system issue remains unresolved. 

ASKAP is powering down and will not operate over the weekend.  The repair contractors are based in Adelaide and are attempting to remote in but not experiencing any positive outcomes for their efforts to identify the fault and repair the fault.

CSIRO will depart site at 1400h WAST.  They will not return to site till ~1200h Mon 13 Jul.  Based on this timeline and the complexity of this fault, all instrument managers are unlikely to have equipment and instruments online before AM Wed 15 Jul. 

MWA Ops will be provide further updates PM Mon and PM Tues on any new developments.  Unless the updates provide a different timeline, all instruments managers will NOT have access to their instruments or equipment before AM Wed 15 July 2020.

As always, any issues or queries please send to operations@lists.mwateelscope.org

UPDATE 15 JUL 2020

The cooling system issue remains unresolved.

ASKAP remains powered down and is only operating intermittently.

CSIRO and the equipment contractor are continuing to work on a solution to the fault.

At this stage, access to all instruments and equipment on site and in the correlator room remains restricted.  access is only provided on an as required basis.  This will prevent equipment and instruments experiencing damage whilst operating in circumstances of high temperature. 

At this stage, instrument managers should not expect access to their equipment or instruments before Wed 22 Jul 2020.

MRO site wide power outageAll MWA, SKA and external instrumentsUnknown

Update 22 Dec 2020

The source of the power outage was a blown EM filter on a LV supply that provided power to the correlator room.  The correlator room lost power and some HV breakers tripped across the site.  Fortunately, the Curtin site area did not lose power.  Only equipment within the Curtin racks of the correlator room lost power.

All MWA, external instruments, AAVS and EDA2 field equipment did not lose power and a quick remote check has identified no obvious damage.  It is recommended all instrument managers check their field instruments and advise of any concerns to operations@lists.mwatelescope.org

Correlator room equipment and machines are now being brought online.  Should anyone have any concerns or issues with their equipment in the correlator room please email operations@lists.mwatelescope.org.

There will be no further updates regarding this power outage.

Update 21 Dec 2020

As at Australian WST1100h 21 Dec 2020, power was lost to all instruments, telescopes and equipment at the MRO.  On site CSIRO staff were unable to identify the cause of the fault.  Tomorrow 22 Dec 2020, electrical contractors and other CSIRO staff will travel to the MRO to support the repair effort.

Loss of power in correlator roomAll MWA, SKA and external instruments and equipment within the MRO correlator room

Unknown - under investigation

The MRO Correlator room will remain without power for an unknown period of time.  The cause and significance of the power outage remains under investigation.

The next information update will occur before COB Wed 29th July. 

Should you have any questions or concerns, please contact operations@lists.mwatelescope.org.

Please do not contact CSIRO / MRO staff directly.  The staff members are very busy and are cognisant of the implications of the power outage.

UPDATE: 30 Jul 2020

The power outage in the correlator room was caused by the activation of fire suppression systems.  The fire suppression was activated 23 July in response to a small component failure on a PCB that emitted particulate and smoke into the correlator room environment.  The cause for the activation of the fire systems has been investigated and identified. 

CSIRO are currently focussed on reinstalling and re-certifying all the components necessary to bring the fire suppression systems back online.  Power was quickly restored to the c-room but without fire control systems, equipment and instruments cannot be returned to operational status.

CSIRO have advised this process is likely to be complete by the 14th August. 

UPDATE: 14 Aug 2020

CSIRO have advised that works continue on recertifying the correlator room fire suppression systems but it is unlikely that instruments and equipment will be back online 17 Aug 2020.  The next update will be provided 21 Aug 2020 unless further information from CSIRO is provided in the interim.  CSIRO are aware of the impact this is having on all MRO users and are working with contractors to bring the MRO back online as quickly as possible.

UPDATE: 25 Aug 2020

CSIRO have advised that the fire suppression systems are being repaired.  However, during the repairs one of the gas canisters containing fire suppression gasses activated.  This has prevented the correlator room returning to operational status.  CSIRO are currently conducting a risk assessment to determine the level of risk associated with a reduced capacity to suppress a fire in the correlator room.  The outcome of this risk assessment will determine when and if the correlator room is returned to operational status this week.

UPDATE: 26 Aug 2020

CSIRO have advised they are willing to accept the reduced fire suppression system risk. The equipment in the correlator room is in the process of being brought online.

Power outage in C-room

All MRO instruments

The 23rd May correlator room outage was triggered by a release of fire suppression gas.  The gas release triggered a power shutdown.  The sudden loss of load on the power generation facility resulted in the power generation facility shutting down for approximately one second.  The power generation facility came back online via diesel generators.


CIRA operations staff have not identified any damage to equipment or instruments as a result of the rapid power cycle. 


However, all equipment in the correlator room within the Curtin racks is not protected by a gaseous fire suppression system in the event of an actual fire. Therefore, as a safety measure ALL  equipment and instruments within the correlator room will be powered down by 1600h WST 29 April.  It is expected that all equipment will remain offline to at least the 10 May. 

UPDATE

MWA correlator will remain offline pending the outcome of the causes of equipment failure.  All other instruments and equipment can continue to operate as normal
