Firmware Upgrade Instructions
NOTE: This example shows
uploading new firmware directly from
a disk. For a faster upload (and less
potential for file corruption), copy the
new firmware to the local hard drive
and upload the new firmware from the
hard drive.
b. Some firmware is in self-extracting compressed files
(files with .exe extensions). For firmware in such files,
from Windows Explorer double-click on the file and
select the directory on the hard drive where you want to
access the uncompressed files. Verify that these
uncompressed files have an .s19 extension.
Step 2. Type REC <Enter> at the SEL
BOOT !> prompt to command
the relay to receive new firmware.
!>REC <Enter>
Caution! - This command erases the relays firmware.
If you erase the firmware, new firmware must be loaded into the relay
before it can be put back into service.
The relay asks whether you want to erase the existing firmware.
Are you sure you wish to erase the existing firmware? (Y/N) Y <Enter>
Step 3. Type Y to erase the existing firmware and load new firmware.
(To abort, type N or press <Enter>).
The relay responds with the following:
Erasing
Erase successful
Press any key to begin transfer, then start transfer at the PC <Enter>
Step 4. Press <Enter> to start the file transfer routine.
Step 5. Send new firmware to the relay.
a. From the Transfer menu in HyperTerminal, choose
Send File (Figure B.14).
b. In the Filename text box, type the location and
filename of the new firmware or use the Browse button
to select the firmware file.
c. In the Protocol text box, select 1K Xmodem if this
protocol is available.
If the computer does not have 1K Xmodem, select
Xmodem.
d. Click Send to send the file containing the new
firmware.
You should see a dialog box similar to Figure B.14.
Incrementing numbers in the Packet box and a bar
advancing from left to right in the File box indicate that
a transfer is in progress.
Receiving software takes 10–15 minutes at 38400 bps,
depending on the relay. If you see no indication of a transfer in
progress within a few minutes after clicking Send, use the
REC command again and reattempt the transfer.
After the transfer completes, the relay displays the following:
