Frequently Asked Questions

What does the -501 suffix on 839492-501 mean?

HPE uses numeric suffixes to denote regional or revision variants. The -501 suffix typically indicates a regional configuration (e.g., different AC power cord or regional certification). The core PSU/BBU hardware and specifications are identical to the 839492-001 (-001) variant.

Is 839492-501 interchangeable with 839492-001 and P04034-001?

Yes — all three are HPE 800W PSU with BBU for Primera 630 with identical core specifications. 839492-501 is the regional variant, 839492-001 is the base spare, and P04034-001 is a newer spare designation — fully interchangeable in Primera 630 PSU/BBU slots.

Can the Primera 630 PSU/BBU be replaced while the array is running?

In redundant PSU configurations, a failed PSU/BBU can typically be hot-swapped while the array continues operating on the remaining PSU. Verify Primera 630 power redundancy configuration and follow HPE Primera 630 service procedures before performing live PSU/BBU replacement.
