NEW FLASH MODULE FOR 1720

Hi!,

I have a Cisco 1720 with 4MB of flash memory. I have installed a 8MB flash module and when the router boots it appears:

System Bootstrap, Version 12.0(3)T, RELEASE SOFTWARE (fc1)

Copyright (c) 1999 by cisco Systems, Inc.

C1700 platform with 32768 Kbytes of main memory

device does not contain a valid magic number

dir: cannot open device "flash:"

After this the router enters ROMmon. From this menu i have copied the new ios to the empty flash with TFTP and the transference completes OK but when I do >dir flash: it appears:

device does not contain a valid magic number

dir: cannot open device "flash:"

I also have tried to copy the ios to the new flash module with xmodem and the error i get is:

Ready to receive file c1700-y-mz.122-4.T ...

Erasing flash at 0x607f0000

Programming location 603a0000

Download Complete!

device does not contain a valid magic number

loadprog: error - on file open

I would be very grateful if someone could tell me what should i do or what is failing. Is there a procedure to install a IOS to a flash for the first time. Do i have to configure something when the flash is new?

Thanks in advence,

Nuria

Re: NEW FLASH MODULE FOR 1720

The manual at http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/1700/1700cnts/upgrdmem.htm#xtocid271968 doesn't say anything about initializing or formatting the flash so I suspect you have a bad module.
