4. The binary buffer area appears, and one of the buffers will display an active state. The
other buffer may be empty or may have a file in it. Verify that the kernel version on the
lower half of this screen indicates
5.0.1
with a
checksum
of
0x12A459
.
5. If both buffers have files in them, highlight the buffer that is not active. Press the
Enter
key, and four options will appear at the bottom of the screen.
6. Using the arrow keys, highlight the
erase
parameter and press
Enter
. When the system
finishes erasing the buffer it will indicate an empty state.
7. Using the arrow keys, highlight the empty buffer area and press
Enter
. Four option
parameters will again appear.
8. Using the arrow keys, select the
download
parameter and press
Enter
. Two option
parameters will appear at the bottom of the screen.
9. Highlight the
TFTP
parameter and press
Enter
.
10. A
mismatch retries
entry appears. Press
Enter
to invoke the default.
11. A
time-out retries
entry appears. Press
Enter
again to invoke the default.
12. An
IP address
option parameter appears. Enter the appropriate IP address of the PC or the
TFTP server into this field and press
Enter
.
13. At this point a
file
parameter appears, prompting for the name of the file being
downloaded to the system. Enter the file name as shown when scanning directories using
the C:\DIR/W command and press
Enter
. If using Windows Explorer the file may be
truncated and the system will not be able to find the file.
If the download process is successful, a decreasing number of bytes begins to appear on
the screen. If something has been configured incorrectly, data will not be sent and
following expiration of the time-outs an error message appears.
14. Upon successful download completion, set the inactive bin to active. This will place the
newly loaded code into an active state and the system will perform a restart. Verify that
all circuits are active and operating.
15. Repeat this same procedure on the inactive bin (previously the active bin) by erasing the
existing firmware and downloading the new firmware so that both buffers have the same
firmware applied to them.
