4.2.1Unsuccessful Update
If the update firmware command fails, DO NOT turn off or attempt to reboot the SmartCell 6A000 switch. In its current state, the operating software normally stored in flash RAM is erased. The switch is still functioning only because it is running the image of the operating software that resides in volatile system memory.
If possible, determine why the update firmware command failed. Common causes for failure are
•Incorrect path and file names
•Improper permission settings on the directory containing the upgrade software
•SmartCell 6A000 is not physically connected to the network
•SmartCell 6A000 cannot reach the TFTP server subnet
If you can correct the problem, enter the update firmware command to continue with the upgrade process. However, if you are unable to correct the problem, use the df (download flash) command and a tftpboot server to replace the operating software. Follow the procedure described in the next section.
