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)

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

I believe you should first issue this command
flash_init
switch: flash_init
