Upgrade IOS Problem for C2960

There are three 2960 took this problem:

WS-C2960-48TC-S 12.2(25)  2

WS-C2960-24TC-S 12.2(25)  1

upgrade from 12.2(25) to 12.2(50)

upload the IOS by TFTP to flash:

boot system flash:****

wr

reload

Failed to get configuration
Invalid parameter block -- no mac address available.
Xmodem file system is available.

The system has been interrupted, or encountered an error
while non-volatile environment variables were being read
out of flash.  If you interrupted the system, it would be
a good idea to issue the reset command now, or the
environment variables may be lost.  The following
commands will initialize the flash filesystem, and finish
loading the operating system software:

    flash_init
    boot


switch: flash_init
Initializing Flash...
...no flash filesystems found.

than i try to type some command:

switch: dir

List of filesystems currently registered:

xmodem[0]: (read-only)
null[1]: (read-write)


switch: flash_init
Initializing Flash...
...no flash filesystems found.

switch:

i try to sent original IOS to null: filesystem and successed, but after reboot nothing happen...

is this a hardware problem? just like flash card get crashed....

any suggestion?

thanks and Best REgards

Type "i", press enter and try again.  Do you get any output when you type "?"?

Parveen,

Are you trying to upgrade your IOS or your current IOS does not load?

Re: Upgrade IOS Problem for C2960

only you can do that buy the service of smartnet for the 2960, and change the new one, back the old to factory.
