Appendix A: FLASH Upgrades
The DS1800 FLASH upgrade feature allows you to update your unit with
the latest firmware available. To perform this update, you will first need a
Trivial FTP (TFTP) server. If you do not have a TFTP server, there are several
shareware programs that you can download.
You can find a freeware TFTP server at http://klever.net/kin/canned/PumpKIN.exe
Next you will need to download the latest FLASH firmware from Avocent at
http://register.avocent.com. Save the FLASH upgrade file to the appropriate
directory on the TFTP server.
Once this is complete, the following steps will upload the new FLASH file:
1. Connect a terminal or PC running terminal emulation software (such as
Hyperterminal) to the Terminal port on the front panel of the DS1800 using
the supplied null-modem cable. The terminal should be set to 9600 baud, 8
bits, 1 stop bit, no parity, no flow control.
2. If the DS1800 is not on, turn it on now. After approximately 10 seconds,
press any key to access the main menu.
3. You will see the Terminal Applications menu with six options. Select
Option 2, Firmware Management. (Please note: the current version of your
firmware will be displayed on the Firmware Management screen.)
4. Select Option 1, FLASH Download.
5. Enter the IP Address of your TFTP server and press Enter.
6. Enter the name of the file that you downloaded from the Avocent site.
7. Confirm the TFTP download by entering a Y or yes and pressing Enter.
8. The DS1800 will verify that the file you downloaded is valid. Next, you will
be prompted to confirm the upgrade. Enter a Y or yes and press Enter
to confirm.
9. The DS1800 will begin the FLASH upgrade process. On-screen indicators
will display the upgrade progress. When the upload is complete, the DS1800
will reset and upgrade the internal subsystems.
WARNING: Do not cycle power to the DS1800 during this process. A loss of power will render the
DS1800 inoperable and require the unit be returned to the factory for repair.
10. Once the upgrade is complete, a verification message will appear on screen.
