The current economic situation has many companies tightening their budgets for new equipment. As a result, data center managers should put greater focus on maintaining their current assets through a PM program. Taking this approach can greatly reduce the need to repair or replace important components.

 

When correctly implemented, PM visits ensure maximum reliability of data center equipment by providing systematic inspections, detection and correction of incipient failures, either before they occur or before they develop into major defects that could translate into costly downtime.

 

To keep running through power outages, utility spikes, and other unforeseeable power issues, critical systems depend on the reliability of the UPS (Uninterruptible Power Supply) system. Therefore, keeping these systems in working condition is crucial.

 

Small UPS devices should be inspected annually to ensure alarms, filtering, and internal batteries are all operating within specifications. For medium and large systems, vendors often recommend that inspections and maintenance take place at least twice a year to ensure proper function and operation within the manufacturers specifications.

 

Battery maintenance begins with installation. Batteries must be fully charged, battery room conditions verified, and baseline readings set for proper trend analysis throughout the life of the battery. Battery aging accelerates dramatically as ambient temperature increases.

 

UPS systems and batteries operate at high voltage and only qualified personnel should attempt preventative maintenance or repair. End users can provide preventative support such as replacing air filters when dirty, ensuring environmental specifications are met and maintained, and monitoring UPS for alarms.
