Firmware Update Procedures
Occasionally it may be necessary to update the Serial Device Server to take advantage of new
features or to fix specific problems. The simplest way to perform this update is with the Silex
UpdateIP utility for Windows XP and 2000 computers. This utility can be found on the CD-ROM that
is included with the Serial Device Server, or it can be downloaded from the Support & Downloads
section of the Silex website (www.silexamerica.com).
When updating the firmware, it is important that power not be removed from the module until the
update operation is complete. Power interruption during firmware update can corrupt the firmware
image and render the device unusable. The Cryptographic Officer should be sure the update has
completed and the unit has reset and returned to normal operation before removing power from the
unit.
To use UpdateIP:
1. Download the appropriate firmware update file from the Support & Download section of the Silex
website (www.silexamerica.com) into a directory on your computer.
2. Download or copy the UpdateIP software files into a directory on your computer.
3. Double click the updateip.exe icon to start the UpdateIP application.
4. Click OK when you get the About Update for TCP/IP splash screen
5. When you get the Select Update File screen, locate the firmware update file that you
downloaded in step 1, and double click on the file name.
6. You will get the Update Files screen. The firmware update file that you selected should appear
on this screen. Click OK.
7. The program will search the local network for Serial Device Servers. Click OK when the search
process is complete.
8. A list of available Serial Device Servers will appear. Highlight the Serial Device Server(s) that
you wish to update.
9. From the menu bar, select Update and then Start to update the Serial Device Server(s).
If you cannot use UpdateIP, you can use the trivial file transfer protocol (tftp) to update the Serial Device
Server firmware:
1. Download the appropriate firmware update file from the Support & Downloads Section of the Silex
website (www.silexamerica.com) into a directory on your computer.
2. If you are using Windows 2000, XP, or Vista, enter the following command from the command
line of your operating system:
tftp -i ipaddress put filename <password>
