Upgrading Firmware
Periodically, EndRun Technologies will make bug fixes and enhancements to our products available
for download from our website. All such downloads are freely available to our customers, without
charge. After you have downloaded the appropriate FLASH binary image file from the EndRun
Technologies website, you are ready to perform the upgrade to your distribution chassis.
For instructions on upgrading firmware using the serial port see Appendix B - Upgrading the Firm-
ware
. This section contains instructions for upgrading firmware via the network port. Upgrading
firmware via the TCP/IP network interface is supported using Telnet only. Upgrading via SSH is not
supported.
CAUTION
Make sure only one port (serial or network) is active during the upgrade procedure. In other words, if us-
ing the network port to upgrade, make sure there is no activity on the serial port.
What You Need To Perform the Upgrade
You will need a terminal program which can connect to your FDC3302 via Telnet and supports file
uploading using protocols XMODEM 128 with CRC or XMODEM 1K with CRC. These are very
common file transfer protocols and should be supported by virtually any terminal program. Less
common is a terminal program capable of connecting using Telnet. A recommended program for the
Windows platform is ZOC, available from Emtec: http://www.emtec.com .
Performing the Upgrade
Configure your terminal program to perform XMODEM file transfers with CRC, using either 128
byte blocks or 1K (1024) byte blocks. Then issue this command:
upload<CR><LF>
After issuing this command, you will see the distribution chassis respond with this message:
Waiting for download using XMODEM 128 or XMODEM 1K (both with CRC).
Control X will abort download.
CCC...
You will then see the distribution chassis send the character ‘C’ every three seconds while it is wait-
ing for you to begin uploading the image file. Should you need to abort the upload process now,
send CTRL-X to the cistribution chassis. If you abort at this time, your current firmware will remain
intact. If you abort after the file transfer is in progress, you will not retain your original firmware and
will need to re-upload it. You will have to use the RS-232 port to do that.
Otherwise, start the XMODEM upload using the appropriate method for your terminal program.
During the upload, your terminal program will display some sort of status indication. If the upload is
successful, you will see the distribution chassis reboot, displaying this message just prior to doing so:
Download Complete. Network connection closing.
Allow 90 seconds before re-connecting.
