Iomart will be carrying out a UPS Service, including Impedance testing of the batteries and Firmware version update. This is critical to the continued operation of the Uninterrupted Power Supplies and ensures the units function correctly in an incident scenario.
What will happen? There will be a series of checks and inspections completed by the combined personnel carrying out the work:
• Check the UPS units are operating fault free. • Conduct planned maintenance on x4 UPS units (Impedance and Service tasks). • Commence preparation for Firmware upgrade. • Check Site Generator is running and operating correctly. • Shutdown the UPS units and confirm site power is being fed from mains supply. • Open each UPS Input and Output breakers and confirm units are isolated. • Confirm site is stable and no alarms / warnings exist. • Conduct Firmware upgrade on all UPS units – approx. 1-2hr. • Restart UPS and transfer load from external bypass (Mains supply) to online operation. • Verify the UPS returns to normal operation with no alarms and is supporting site load. • Shutdown Generator and return to standby condition • Take UPS Load readings, confirm accuracy with PDU and IT Loads.
Following reinstatement to normal operation, the combined team will carry out plant checks to ensure there are no alarms present and that all systems are operating as normal.
When will the work be carried out? The maintenance period will be on the 3rd of February 2025, from 0900hrs to 1700hrs. The Work duration is expected to take approximately 4 to 6 hours.
Who will be completing the work? The work will be carried out by iomart Data Centre manager and specialist contractors from Riello and Sudlows.
