TSL Products: A Testament to Durability, But Is It Time for a Refresh?

A recent discovery highlights the remarkable durability of MDUs first sold in 2006 that remain operational today. While this longevity demonstrates exceptional build quality, it also raises concerns about the risks of relying on aging equipment in critical positions.

Durability vs. Operational Best Practices

Modern MDUs and PDUs are engineered to deliver reliability and performance, often exceeding their warranty period. Standard warranties typically cover one year but can be extended up to five years. However, while many devices continue to function beyond 10 or even 12 years, using equipment for such extended periods—particularly under 24/7 operation—is not recommended.

For Tier IV-certified data centers, equipment refresh cycles generally fall between 2–5 years based on usage intensity. Devices under constant load are typically replaced sooner to ensure uptime and minimize risks. As a point of comparison, leading brands such as APC and EATON offer extended warranties capped at 36 months, while others like Raritan and Schneider recommend a maximum useful life of 5–6 years.

Risks Associated with Outdated Equipment

Outdated PDUs and MDUs, especially those over five years old and out of warranty, pose increased risks to uptime, safety, and operational efficiency. While older devices may still function, the likelihood of failure grows with age, potentially compromising critical infrastructure.

A proactive review of equipment age and condition is essential for identifying potential vulnerabilities. Phased replacement strategies based on device age, position criticality, and overall risk help maintain reliability and compliance with modern operational standards.

Practical Steps for Managing Equipment Lifecycles

Organizations can minimize risks by implementing asset management best practices. These include:

• Conducting equipment audits to assess the age and reliability of installed PDUs and MDUs.
• Prioritizing replacements for devices in high-risk or critical roles.
• Extending warranties for units still within recommended operational lifespans.
• Planning phased upgrades to ensure smooth transitions and uninterrupted operations.

While some MDUs have proven capable of functioning for nearly two decades, relying on such outdated equipment introduces unnecessary risks. A comprehensive review and replacement plan help future-proof operations while optimizing safety and reliability.

For further information on warranty extensions, equipment reviews, or phased replacement plans, consider reaching out to specialists in PDU lifecycle management. Reliable power distribution begins with proactive decisions, ensuring the stability and safety of critical systems.
