Hi,
I would like to know if the new ios image file be stored in dram instead of flash.
Because my flash is only 64mb, whereas the requirement for new image is as follows:
Existing image:
IP SERVICES SSH LAN ONLY
s72033-ipservicesk9-mz.122-18.SXF17a.bin
Size: 42036.01 KB (43044868 bytes)
Minimum Memory: DRAM:512MB Flash:64MB
New image to be upgraded is as follows:
s72033-ipservicesk9-mz.122-33.SXI5.bin
Size: 69428.29 KB (71094564 bytes)
Minimum Memory: DRAM:512MB Flash:512MB
As the minimum requirement for new image is 512MB whereas my flash is only 64MB.
So can I install the image in the dram ?

How should I upgrade the IOS, We had to do the ios upgrade remotely.
Thanks to advise.

Hi,
You can directly decompress the IOS image onto the DRAM using xmodem/ymodem or tftpdnld.
However, this can be done only from rommon mode.
The disadvantage of doing this is that, if at all the switch reboots in the future, it will not come up on its own as there is no IOS image locally present on the flash or on the bootflash from which it can boot from.

Hi Dheeraj ,
Is there any document to validate this statement, if yes, then I shall forego this mode of upgrade and rather wait for CF to be purchased

The more common solution is to buy a compact flash card that you can use in one of the available slots in your chassis. Then copy the IOS to the compact flash card and set the boot variable to point to it.
We did this on a number of our 6500 switches because we did not have enough internal memory on the supervisor.

I agree with Jon. Get a compatible CF (maximum 2Gb but others say 4Gb or 8Gb is possible but I haven't tried it).

Thanks Guyz. Yes CF is the best option. But due to time constraints had to try directly decompress the IOS image in to DRAM as Dheeraj suggested ;-) Will update after the upgrade
