Bootflash file for Cisco Catalyst 2948g L3 Switch?

Question

Hi Guy,

I deleted my boot flash from the switch and now am unable to load up anything. On start up this is what I am getting...

ROMMON: Cold Reset frame @0x00000000
ROMMON: Reading reset reason register
ROMMON: Valid NVRAM config

System Bootstrap, Version 12.0(7)W5(15) RELEASE SOFTWARE
Copyright (c) 1998 by cisco Systems, Inc.

ROMMON: Initializing exceptions
ROMMON: Initializing TLB
ROMMON: Initializing cache
ROMMON: Sizing and zeroing main memory ... 64 MBytes
ROMMON: Sizing non-volatile memory ... 128 KBytes

cat2948g platform with 65536 Kbytes of main memory

device does not contain a valid magic number
boot: cannot open "bootflash:"
boot: cannot determine first file name on device "bootflash:"
rommon 1 >
rommon 1 >
rommon 1 >

I have done a little digging around and it seems the only way to solve this is to re-install the boot flash file using xmodem which is fine, but the file is nowhere to be found. Cisco have a 2948g L2 on their website but I need a special log in to get it.

Does anyone know where I can get this file of know of any other solution ?

Many Thanks!

You'll have to look around for someplace that provides IOS images. Cisco requires you to have a valid support contract first.



I'm not sure, but at one time anyone could have a login to Cisco.com, and I think you get IOS images for obsolete hardware (not familiar with 2948g), so if that's the case, give that a try. Also, if you happen to live near somewhere that has a Cisco Academy learning program, the instructors have access to any firmware. So if you asked nicely...

Have you tried to see if the file is actually still there in flash?

It looks like it's expecting to find the OS in bootflash: so try these commands from the command prompt

show bootflash:

dir bootflash:



Although you could try these as well

show flash:

dir flash:



It is possible the file has just been marked for deletion, if so you can recover it with the undelete command



What you're looking for is a .bin file showing [deleted] at the end of the line



You can check this general document though about file management in flash
