Hi,
I have a C6100 unit that had a faulty FCB. The board has been changed (supplier sent a new one) but now, after the initial burst of speed at boot, the fans refuse to increase speed beyond 1600rpm (IPMI reading) and the processors are hitting 80+ DegC.
Any thoughts or testing anyone can suggest.
Thanks
RB

- Removing the chassis top does not cause the fans to change speed (it does usually due to lack of directed airflow to the top two nodes).
- Removing a node and not blocking the hole does not cause the fans speed to increase.
- Have tried with BIOS 1.71, BMC 1.33, FCB 1.20 and after regressing to BIOS 1.70, BMC 1.32, FCB 1.18 with no change.
- Connections to the FCB all look fine. The right hdd backplane starts with the correct node from the front power button.
- The bios has been reset to 'defaults safe' to clear anything that may be causing issues.
Any thoughts or testing anyone can suggest.
Thanks
