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: (read-write) xmodem: (read-only) null: (read-write) bs: (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?

I have always read how it is the best security practice to put unused ports on switch/router into shutdown state. However, at work they put them in unused VLAN which serves just for this purpose.
The only config on that interface:
#switchport mode access
#switchport access vlan 111
By the way, VLAN 111 is active.
I searched a lot on this topic but still do not have the answer. Is it a good security practice? And is it better than shutting down the ports?
Thank you very much for any help :)
