Problem Suggested Solution
Getting “Address
Range” error
message and boot
up is failing.
This error message appears when a 4-MB Catalyst 2900 XL switch is upgraded
to an image that is not supported on this hardware. The switch in this case tries to
load the image, but because this switch is not capable of loading this image, the
bootup process fails. This also happens in cases when a 4-MB Catalyst 2900 XL
switch is upgraded to an IOS 12.0 image.
Download the IOS Image File by using X-Modem.
Getting “No Such
File or Directory”
error message
during bootup.
This error message appears when the names of the bootable file and the actual file
in the Flash differ. This usually happens due to a mistyped file name when setting
the boot parameters, during or after the upgrade.
Go to Setting BOOT Parameters at ROMMON (Switch: Prompt) to verify and set
the BOOT parameters correctly.
If setting the BOOT parameters to the correct file name does not resolve the issue,
perform an X-Modem upgrade, as the file present on the Flash memory could be
corrupted or invalid.
