Hi,

The Cisco 1721 router supports a maximum 128MB DRAM, so yes you can upgrade your memory.

Edgar,

You have to open the router and then put the memory in a spare DIMM module. You have an onboard 64MB Dram and you have use the part number MEM1700-64D= to get an additional 64MB memory. Put the meory in spare DIMM mdoule. Please use the link below for the same:

Edgar,

The MAX memory size supported on 1721 router is upto 128MB. This product has already reached EOl/EOS. It will be very hard to get the parts for it now. Check with a local reseller if you can get an addtional 64MB memory and upgarde it to 96 MB. You are already running 64MB DRAM on this.

http://www.cisco.com/en/US/products/hw/routers/ps221/prod_eol_notice0900aecd8044473f.html

Here is the part number for this memory:

MEM1700-64D=

Please see the documentation for upgrading the memory on the router:

http://www.cisco.com/en/US/products/hw/routers/ps221/prod_configuration_guide09186a0080099429.html

HTH,Please rate if it does.
