Frequently Asked Questions
Can I mix different wattage PSUs in a server?
Most enterprise servers require matched PSU pairs for redundancy. Mixing wattages will cause the server to run in non-redundant mode or refuse to boot. Always replace with the exact same wattage and part number as your existing PSU.
What does hot-swap mean for power supplies?
Hot-swap means you can remove and replace a power supply while the server is running — zero downtime. In a redundant configuration (2 PSUs), one PSU powers the server while you swap the other. The server never loses power during the replacement.
