Most UPS vendors publish an MTTR figure. Few demonstrate it. This is a live CumulusPower module replacement, completed in 2 minutes 35 seconds, with the system under load and no transfer to bypass.
The same safe hot-swap architecture applies across the StratusPower range.
What you just watched:
- Module replaced with system live under load — no maintenance window required. The same concurrent maintainability applies to StratusPower.
- No transfer to static bypass at any point — tenant feeds unaffected throughout
- Replacement module isolated and tested within the running frame before accepting load — human error eliminated at the architectural level
- Total elapsed time: 2 minutes 35 seconds
Why this matters for your facility?
A maintenance window in a live colocation facility is a scheduled SLA risk event. It requires customer notification, contractual management, and reputational exposure.
Concurrent maintainability — the ability to replace a module without interrupting power to the critical load — eliminates that exposure entirely.
What you just watched is a live CumulusPower module replacement. The same safe hot-swap architecture is built into StratusPower.
It is not a controlled lab demonstration. It is the standard maintenance procedure for every Centiel modular UPS installation.
The architecture behind it
Safe hot-swap is an architectural property, not a maintenance technique.
Centiel’s DARA architecture — shared across both CumulusPower and StratusPower — ensures every module contains its own static bypass, control logic, and isolation capability.
Any module can be removed and replaced without the system ever transferring load to a shared bypass. Read how DARA architecture eliminates single points of failure
