One of my client have one MCS7816-H3 server with 2GB memory. Now they want to upgrade this server with 4GB memory. When I search in cisco I found that MEM-7816-H3-2GB= is the part number for the particular server. But this part is in EOS. Can any one know that there any replacement for this part?. One of my distributor send me MEM-7816-I4-2GB= as a replacement. Is this part is compatable with the above server?.
