Updating Controller Firmware
The following information describes the procedures to update the firmware on
the RAID Controller. The preferred method is to take the system off-line first, then
perform the upgrade. This prevents bus reset errors.

Obtain the new or updated controller firmware file. You may download the
file from the support section of our web site.
2 Connect the USB end of the NexStor Communication cable to the RS-232
Service port on the RAID Controller. The cable is included with the storage
system.
