Hi all,
I have wiped out the IOS of a 2950 Series Swich:
When the switch boots i get the follwoing output:
Parameter Block Filesystem (pb:) installed, fsid: 4
Loading ""...: permission denied
Error loading ""
Interrupt within 5 seconds to abort boot process.
Boot process failed...
The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable
image.
switch:
The "permission denied" message in my understanding implies that i cannot use a tftp server to install a new ios on the switch so i have to go through the xmodem file transfer.
However the procedure keep fails with the same message:
Begin the Xmodem or Xmodem-1K transfer now...

I perform the fsck flash: command and re try. I get the same error.
Then i tried with a different ios (c2950-i6q4l2-mz.121-22.EA9.bin). Nothing changed.
I have hit a deadlock, could you please help me on how to proceed?
Below i list some info about the switch and the IOS am trying to send:
Swicth: WS-C2950-24
IOS: c2950-i6q4l2-mz.121-22.EA14.bin
As a guide i have used the following document:

Thank you for your time.

Hello leolaohoo
I turned on the switch and I posted the dir flash:
As you can see I had some issues that lead me to format the flash (for one more time)
I was surprised to notice that this time the format worked! I have been unsuccessfully trying to format the flash the previews week.
Then I decided to send the file again and this time it was successfully send. The switch now is ok
below is the console output:
