Cisco catalyst 2950 cannot boot

Hello,


I have a problem with one of our Cisco Catalyst 2950 switch. It was functional but we cut the power off for the whole rack and this one didn't boot. Both uplink ports shine amber and SYST led is blinking green. This does not change the whole time.

Through console I can access the switch only in some pre-boot mode, but I can't access the flash:

switch: dir

List of filesystems currently registered:

flash[0]: (read-write)
xmodem[1]: (read-only)
null[2]: (read-write)
bs[3]: (read-only)

switch: dir flash:
unable to stat flash:/: invalid argument
switch: dir flash:/
unable to stat flash://: invalid argument
switch: dir flash
unable to stat flash/: no such device

switch: version
C2950 Boot Loader (C2950-HBOOT-M) Version 12.1(14)AZ, RELEASE SOFTWARE (fc2)
Compiled Tue 14-Oct-03 17:14 by antonino

switch: boot
Loading ""...: no such device

Error loading ""

Interrupt within 5 seconds to abort boot process.
Boot process failed...

I already tried flash_init and load_helper commands, but no luck..

So I guess the switch does not have image from which to boot? Maybe the flash memory is corrupted? Is here still any way how to fix this?

As suggested other member, you can go for RMA

 

or try format and see if that works 

 

Switch : format flash:

if that working then load the image using xmodem

Hi
looks like the flash is gone which means RMA replace but its very old switch so it may not be supported unless you have it backed out to a local supplier

It worked, after formatting I could dir the flash and via xmodem load bootable image, thank you :]

I believe you should first issue this command

flash_init

switch: flash_init
Initializing Flash...

switch: dir flash:
