Error updating bootrom
You may re-install the Flex Port module(s) after successfully completing the OS and Boot ROM update.
RECOVERY STEPS: If you perform an OS update on a system which has the listed modules installed and encounter the issue, the unit may be recovered by manually completing three system boot-up sequences as described within this document.
When performing an OS update from KB. that also includes a Boot ROM update beyond KB., the switch may fail to complete the update process.
In the case that the update fails (i) the unit will halt during boot-up and remain in a state where all LEDs remain on, and (ii) if the serial console is attached and active during the boot-up sequence, the console will display a message similar to the following: ATTENTION : This release includes an important upgrade. Please contact HP Networking Support for further assistance.
