Brocade FastIron Ethernet Switch Stacking Configuration Guide - Manual (Page 58)

Converting from a pre-stacking image to a stacking image
When you boot a stacking image (release 05.X or later) on a device with a pre-stacking (pre-release
05.X) startup-config.txt file, the system automatically converts the interface format from 0/X/X to 1/X/X.
In addition, when a write memory command is issued, the pre-stacking startup-config.txt file is
renamed to start-config.v4 and saved as a backup file.
NOTE
If you enter the erase startup-config command or stack unconfigure clean command, all startup-
config txt-related files, such as startup-config.v4 and startup-config.old are erased. You will no longer
be able to recover pre-stacking startup-config.txt files.
Encountering a problem after upgrading and reloading the software
If you encounter a problem after upgrading and reloading the software, make sure the device has the
correct boot code version and the following (if applicable) are installed correctly:
• EEPROM
• Memory DIMM
If the stacking EEPROM is missing or is not installed correctly, or if you have installed the wrong
EEPROM, you will see output similar to the following.
FCX MEM size: 0x10000000
FCX Flash config....
FCX Boot Code Version 05.0.01

When you have confirmed that your hardware upgrade is installed correctly, restart the system and
check the software version using the show version command.
