Hi Experts

I'm trying to make my old Cisco 1751 router usable again, and I wish to be abel to load both an IOS image and Cisco SDM and ig posible Cisco Unified Callmanager. but I only have 16384K bytes of memory, is it posible to upgrade the memory or load everything but the IOS from a TFTP server?

Best Regards

I'd upgrade the memory:

Thank you very much for your reply.

I'v looked at the page you suggested, but as fare as I can see the only thing I can upgrade is the DIMM ram, would that solve my problem with not beeing able to fit the wanted software in the flash memory?

I'm a little confused aboudt, where the router uses what memory and what gets erased during a power failure.

2PiFL

The IOS and SDM software are stored in flash. The startup-config will reside in nvram. The dimm will be used by the router for overhead and will be erased on a power failure. Flash and NVRAM will not be erased during a power outage.

According to this document:
http://www.cisco.com/en/US/docs/routers/access/1700/1720/hardware/notes/1700UMem.html#wp1087299

You can have as much as 32M of flash. The IOS and SDM will need to "fit" in flash.

I only have 16Mb of flash, and the ios and sdm wont fit to flash, only one of them, so is it posible to launch SDM directly from tftp?
