About Code
and
Configuration
Files
All D25 units require two distinctly different files to be loaded into memory
before the unit will become operational:
• Code File
− This file is created using GE Grid Solutions’ Software Development
System, and is used to define the applications that can be used in a D25
system.
• Configuration File
− This file is generated using the SGConfig configuration tool, and is used to
enable and configure the operational characteristics of the applications
defined by the code file.
!
Extremely
Important
The Code File and the Configuration File loaded into any D25 must match
perfectly:
• The applications and application versions used in the configuration files created
using SGConfig must be the same as the applications and application versions
used to make the code file.
Any differences between the applications in the code and configuration files
may result in erratic or unpredictable behavior of the D25
How can
Configuration
and Code File
Mismatch
Happen?
Here are some common ways that this can occur:
1. The wrong configuration file is accidentally downloaded into a unit. For
example, based on a D25 that has a different code file installed. This can happen
either:
− Through a local serial SGConfig download, or
− Remotely over a LAN connection using TELNET or BootP
2. A code file is downloaded that does not match the configuration file that is
presently resident in the D25’s NVRAM
3. Either the code file or the configuration file has been corrupted, either before or
during download
How can
Mismatch be
Prevented?
1. Wrong configuration file: usually a result of operator or BootP Server
configuration error, and can only be prevented by exercising care.
2. Mismatched code file: can be prevented by erasing any configuration file that
may be resident in NVRAM before downloading a new code file.
3. Corruption: may require the regeneration of one or both files, and re-
downloading.
