Unsuccessful 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.
