The Firmware Update operation lets you upgrade the IO Accelerator's firmware. You should upgrade
the firmware only if:
• The Windows System Event Log reports a problem due to out-of-date firmware or
• if instructed to do so by HP Customer Support.
NOTE:
In most cases, if you upgrade the IO Accelerator firmware you will need to upgrade the IO
Accelerator driver as well. Most support issues arise from mis-matched firmware and drivers.
IMPORTANT:
You should first detach the selected IO Accelerator(s) from the system to ensure a clean firmware
update.
WARNING!
Warning: It is extremely important that the power not be turned off during a firmware upgrade,
as this could cause device failure. If one is not already in place, consider adding a UPS to the
system prior to performing a firmware upgrade.
NOTE:
Upgrading the firmware may take some time. Monitor the progress using ioManager.
IMPORTANT:
For ioManager to properly write the firmware upgrade to the device, you must shut the system all
the way down and bring it all the way back up—not just perform a restart.
