Cisco 2948G-L3 boot problem? Ideas? 1

[Prizmm]

We just recieved a Catalyst 2948G-L3 and we want to use it for a switch in one of our buildings. The problem is this: When we power it up, it says


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

System Bootstrap, Version 12.0(7)W5(15a) RELEASE SOFTWARE

cat2948g platform with 65536 Kbytes of main memory

loadprog: bad file magic number: 0x0
boot: cannot load "bootflash:"
rommon 1 >
-------------------------------------------------------

What the heck do we do now? Is the image corrupt? THanks

at the prompt rommon 1> enter "dir" do you see an image listed?

IOS is either missing or corrupt.....
Need to flash it back in....
Two ways to do that are xmodem (slow) or Tftp from rommon mode. (fast)
Place the IOS image in your tftp server directory and start tftp server.
Then enter the following in the switch exactly as below as all are case sensative:
rommon 1> IP_ADDRESS=xxx.xxx.xxx.xxx
rommon 2> IP_SUBNET_MASK=xxx.xxx.xxx.xxx
rommon 3> DEFAULT_GATEWAY=xxx.xxx.xxx.xxx
rommon 4> TFTP_SERVER=xxx.xxx.xxx.xxx
rommon 5> TFTP_FILE=full file name of ios as it reads
rommon 6> TFTP_CHECKSUM=0
this one is in lower case
rommon 7> tftpdnld

If you dont have a tftp server below is a link to a free one

You will need the .bin IOS image for this and not the .tar file. The .tar file contains router cluster management files that you must issue the archive tar command to load all of the files. Can do that if needed after router is back online.

I dont have an image. This switch was here when I started working here and I am pretty sure we dont have a .cco account with Cisco. Where can I get an image for this?

 

[JOAMON]

Did you do a dir flash: as rokk suggested and if so what output:

 

[JOAMON]

Sorry...Rook

 

[Prizmm]

When I type a "dir bootflash:" this is what coems up:

rommon 5 > dir bootflash:
File size Checksum File name
1750311 bytes (0x1ab527) 0x0abb C2900XL-c3h2s-mz.120-5.3.WC.1.bin

 

[JOAMON]

Wrong image for that switch
need on like:
cat2948g-in-mz.120-25.W5.27c.bin

 

[Prizmm]

Any ideas of where I can get that?

 

[JOAMON]

Where did you get the switch from?

 

[Prizmm]

It was here at the School when we took over administration. Can you just buy an image from Cisco or do you have to purchase a .cco account? I have never had much luck with cisco.

 

[JOAMON]

You would usually gain access to downloads with the purchase of Smartnet on a cisco device. Do you have an IT department or person that might have CCO login you could use or are you the man?

 

[Prizmm]

Sadly enough "im the man" Who should I contact about a .CCO? Cisco Directly? Thnaks again for all your help.

 

[RookThis]

Cisco won't talk to you unless you have an account with them.

 

[JOAMON]

Might repost and see if anyone has similiar switch and would be willing to send you copy of the IOS....

 

[JOAMON]

Found you a link....check it out:

[Prizmm]

YOU ARE THE MAN! I can't thank you enough! I'm Dl'ing right now and then I will try and reload it with the above instructions. Thanks again!

 

[JOAMON]

That is even the most current one available for that switch. The instructions above I used on a router but have never tired them on a switch...should work though....
Good Luck....

 

[JOAMON]

Let us know how you make out......

 

[JOAMON]
