LOADFW: Load Firmware onto ESA.
ALL parameter will execute LOADFW on
all ESAs in the post set.
LOADFW UPGRADE must be used to activate
the new firmware.
Parms: [<FILE> STRING]
[UPGRADE {UPGRADE}]
[NOWAIT {NOWAIT}]
[ALL {ALL}]
To download firmware to the ESA, execute one of the following commands.
The following are examples of the LOADFW command.
>LOADFW
or
>LOADFW <file_name>
Note 1: If the firmware file name is not specified with the LOADFW
command, the command applies the firmware file name provisioned in table
XESAINV, field E2LOAD.
Note 2: By using the LOADFW command without the UPGRADE option,
the firmware downloads to the ESA.
Loadfile verification
The system performs integrity checks on the firmware for loadfile accuracy. A
loadfile record length check makes sure the file is a firmware file before the
XPM uses the file. If the record length is not 54, a message is output to the
user and the LOADFW command fails.
Another accuracy check is a 32-bit cyclic redundancy check (CRC) with a
16-bit checksum. The CM sends a validation message to the XPM to check
the accuracy of the firmware load. The XPM extracts the CRC and checksum
that is in the firmware load. The XPM calculates the CRC value and the
checksum. The XPM compares the computed and extracted values to see if the
values are the same. The XPM sends the result of the comparison to the CM.
To verify the firmware load enter the following command at the MAP display
terminal:
