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?

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

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://

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
04-02-2012 12:39 PM
Try:
rommon 1 > confreg 0x2102rommon 2 > reset
If that does not work then I guess now you have to try and boot from the tftp server.
