4.2 Upgrading the Firmware
Upgrading Flash Firmware Programming Utility
Since the RAID subsystem controller features flash firmware, it is not necessary
to change the hardware flash chip in order to upgrade the RAID firmware. The
user can simply re-program the old firmware through the RS-232 port. New re-
leases of the firmware are available in the form of a DOS file at OEM’s FTP. The
file available at the FTP site is usually a self-extracting file that contains the
following:
XXXXVVV.BIN Firmware Binary (where “XXXX” refers to the model name and
“VVV” refers to the firmware version)
README.TXT It contains the history information of the firmware change. Read
this file first before upgrading the firmware.
These files must be extracted from the compressed file and copied to one direc-
tory in drive A or C.
Establishing the Connection for the RS-232
The firmware can be downloaded to the RAID subsystem controller by using an
ANSI/VT-100 compatible terminal emulation program or Remote web browser
management. You must complete the appropriate installation procedure before
proceeding with this firmware upgrade. Whichever terminal emulation program
is used must support the ZMODEM file transfer protocol.
Configuration of the internal RAID subsystem web browser-based remote RAID
management. Web browser-based RAID management can be used to update
the firmware. You must complete the appropriate installation procedure before
proceeding with this firmware upgrade.
