You have no network access to do an IOS upgrade?  Do you have PHYSCIAL access to the appliance?

You don't have admin rights?  Are you even ALLOWED to do an IOS upgrade?

Re: Cisco 4948

Yes, I am allow to do upgrade and I have physical access to the switch, I can use SecureCRT to transfer the IOS, but there is no xmodem option on 4948

Whao!  Whao!  Whao!

Let's step back for a moment here.

XModem?  Can you please elaborate what you mean by this?

I mean if you have permission and you are allowed to upgrade the IOS then WHY don't you have admin access?  What's going on?

Usually I used SecurCRT to upgrade the other devices but not in 4948

You mean copy an IOS version from one 4948 to another 4948?  Sure.

Where the original IOS is from, enter the configuration command "tftp flash:filename.bin".

Where the IOS is going to, copy using the command "copy tftp:///filename.bin flash:filename.bin"

Re: Cisco 4948

Hi leolaohoo<>,

After I download IOS image from 4948 to another 4948 it downloaded the image and showing image

boot system flash bootflash:cat4500-entservicesk9-mz.122-50.SG6.bin.

But when I looked up the dir bootflash: does not show any Image and after reload switch going back to again in ROMMON > prompt

Re: Cisco 4948

Try:

rommon 1 > confreg 0x2102
rommon 2 > reset

If that does not work then I guess now you have to try and boot from the tftp server.

In your new 4948, can you please post the command "dir flash:"?

Re: Cisco 4948

Hi leolaohoo<>,

Switch#dir bootflash:

Directory of bootflash:/

1 -rwx 17338692 Mar 30 2012 14:56:48 +00:00 10.1.1.2

 1  -rwx    17338692  Mar 30 2012 14:56:48 +00:00  10.1.1.2

I believe you've renamed your IOS to "10.1.1.2".

Re: Cisco 4948

No that is the ip address for the switch!

No it is not.

The so-called "IP address for the switch" has a FILE SIZE OF "17338692".   You have renamed your IOS to "10.1.1.2".
