Importance of scheduled UPS maintenance for a secure Data Center
The protection of the power supply to Data Centers, through the use of static uninterruptible power supplies (UPS), is essential to guarantee the continuity of services, as well as preventing possible damage to servers and other electronic equipment susceptible to voltage and frequency anomalies.
Data Centers are often subject to disturbances in the electrical energy that powers them such as, for example, voltage variations, waveform distortions, interruptions, and frequency variations. These impurities, together with possible blackouts, are particularly dangerous and are responsible for the majority of Data Center downtime; disruptions that could have very serious consequences such as data loss, breakdowns, complete interruption of services and considerable increases in energy costs.
To avoid serious disasters and minimise the risk of downtime, it is essential to carry out scheduled and sometimes preventive maintenance of the UPS and its electronic components, which are subject to wear and tear.
UPS maintenance must always take two aspects into consideration:
- it must be carried out by specialized personnel
- it must be managed by those who have a strategic vision of the facility as a whole, including its future evolution.
The maintenance manager must then know how to organize it in different ways, perhaps combined with each other, depending on the needs and characteristics of the specific system:
- on demand following a breakdown or fault
- with a periodic maintenance contract
- with a preventive maintenance mode
- via remote control for remote monitoring of the UPS
Periodic maintenance or remote control?
The main objective of periodic maintenance or remote monitoring of a UPS is to ensure business continuity, as well as assist in an efficiency strategy that leads to a reduction in energy costs and an increase in the level of general safety and performance.
Periodic maintenance requires that careful checks are carried out during the year to assess whether the UPS is functioning correctly, to carry out cleaning, to replace auxiliary components, and to update software and/or hardware.
Remote control, on the other hand, involves monitoring the UPS by connecting it to a network that enables it to be managed from a "remote" location, therefore physically distant from the UPS (perhaps in another building). The information collected by the system on external and internal events and on the status of the UPS is provided directly to the control center of the UPS manufacturer and the UPS itself can decide independently to launch emergency calls by providing information on demand.
