Scheduled
Please be aware of the following emergency maintenance window for essential UPS Maintenance at our Reading Datacentre facility – TVHC1 only.

WHAT
Following on from an alert received this morning on our monitoring system, we are aware of a fault with one of our UPS modules in our UPS array.
We have isolated the module and in line with the manufacturers’ recommendations we have authorised for our specialist UPS contractor to investigate the issue further and bring the module back on line. This is in line with our processes, and to maintain maximum efficiency of our infrastructure as soon as possible.

SERVICE IMPACT
NONE – All UPS arrays are still on line, but in each UPS unit there are multiple modules. One of the modules has gone into fault and has been isolated, which has resulted in reduced resilience in one UPS unit. There will be no planned service impact during the emergency maintenance, but it will required one full UPS unit to be isolated so that the module and unit can be investigated and the issue resolved.
This will mean that on the “A” feed there will be reduced UPS resilience, however, power will remain protected and unaffected to all our customer racks during these essential emergency works. Due to the element of electrical switching that needs to be undertaken, an Emergency "At Risk" notification is being sent out to inform our customers accordingly.
The essential maintenance will be completed by our specialist UPS contractor and the unit will be fully tested prior to returning into the array and returned to normal service.

WHY
The UPS contractor has requested that the UPS module in fault is isolated in order to fully investigate the fault, and check the other modules safely, prior to returning it into the array.

Pulsant's specialist UPS Contractor will be on site to complete the emergency maintenance, supervised by the datacentre management team throughout.

WHEN
Work is scheduled to be carried out during the following maintenance window:

Tuesday 29th November 2016, commencing at 19:00GMT and ending by 22:00GMT on Tuesday 29th November 2016.

The "At Risk" window will be kept to an absolute minimum and the UPS array will be returned to full resilience at the earliest opportunity.

A completed notification will be sent out once the works have been completed and normal service has resumed.
