Q. How do I upgrade my Codian unit using external Compact Flash?

A. Very occasionally, it is necessary to upgrade a unit's software using the external Compact Flash slot. Examples of such situations are:

  • An attempt has been made to install ISDN Gateway software on an MCU or IP VCR (or vice versa), and the unit is repeatedly rebooting such that the web interface is inaccessible

  • A power failure occurred during a previous upgrade attempt and the unit will not boot up to the point where the web interface is accessible

  • The administrator password has been lost and the unit is running a version of software which does not have the reset_config command

Follow these steps to upgrade using external Compact Flash:

  1. Obtain the required version of software as a .zip file from the Codian website.

  2. Extract the image from the .zip file to your hard drive and rename the extracted image kupgrade.

  3. Obtain a Compact Flash card of between 32 and 256 MB capacity, and some means of writing to it. USB compact flash card reader/writers are readily available.

  4. Copy kupgrade on to the Compact Flash card.

  5. Connect a serial terminal to the Console port of your unit using the connection settings on the unit's back label.

  6. Insert the Compact Flash card in to the slot on the unit's front panel and shutdown/restart the unit from the web interface, if it is available: otherwise from the command line type "reboot s" at the prompt.

  7. Watch the output on the serial terminal. After a few seconds, you will see several rows of '.....' appear, followed by a message telling you the number of bytes copied. This represents the copying of the kupgrade image from the external Compact Flash card to the unit's internal memory.

  8. Eject the Compact Flash card from the external slot.

The unit will complete the upgrade process and reboot of its own accord. The process is now complete.
