Temperature sensors drift over time. New firmware includes recalibration curves. Without it, your cooling system might overcompensate (wasting energy) or undercool (frying drives). The Upgrade Process: A Step-by-Step POV Updating the E58650 is not as simple as clicking “Update” in iLO. Because it manages power , a failed update could mean a bricked controller and a rack you cannot manage remotely.
Consequence: If v3.00 has a bug with your specific load shedding script, you are stuck. Always test on one non-production PDU first. A regional colocation provider ran HP E58650 firmware from 2021. When a line card failed, the master controller failed over to its secondary. Because of a race condition patched in the 2023 firmware, the secondary unit froze during the failover, locking the outlet relays in an “on” state. They could not power cycle a crashed database node for 14 hours. hp e58650 firmware
But these units have a brain. And that brain runs on firmware. Ignoring updates for the HP E58650 is not a sign of stability; it is a ticking time bomb for brownouts, rack failures, and silent data corruption. Temperature sensors drift over time
