Commencement Date/ Time

15-03-08/ 1700hrs (SGT) to 16-03-08/ 0930hrs (SGT)

Purpose of Works

Following the recommended cyclical parts replacement guidelines set by the UPS manufacturer, the AC/DC capacitors and fans for the UPS 5-1 and 6-1 have to be replaced. This would ensure that the performance of UPS 5-1, 6-1 (1+1 setup - function as a pair) is maintained within specifications.

Impact on Services

During the implementation work, the customer load on the UPSes will be transferred to external maintenance bypass.
In this instance, Customer’s load will be supported by Raw power from the PowerGrid which are back-up by the building generator supply during the replacement works.
In the event that the raw power supply from the grid is disrupted, customer’s load on single power feed supply (A source/power strip) will be affected.
Customers are advised to backup your critical data or divert your critical services before the implementation period where necessary.

Sorry for any inconvenience caused.

Thanks.
