Was told that I would need to upgrade my firmware. Not sure what version I am currently on and were to locate the latest version and how to upgrade without effecting my users:<BR />"Power enclosure AC power problem (power supply 3, reason: ac power loss, enclosure serial number XXXXXx)" "rack power supply degraded" any advise would be greatly appreaciated. thanks in advance Mon, 16 Mar 2009 19:39:37 GMT https://community.hpe.com/t5/bladesystem-general/power-enclosure-ac-problem/m-p/4380394#M5510 Yvette McGlawn 2009-03-16T19:39:37Z https://community.hpe.com/t5/bladesystem-general/power-enclosure-ac-problem/m-p/4380395#M5511 Upgrading the OA firmware does not impact servers in the enclosure.<BR /><BR />You have to apply the Firmware OA 2.25 (or more) to resolve the main known bugs.
