how can I install 48MB DRAM in the Cisco 1750 Router

[admin_2]

1750 has only one DIMM slot for DRAM.

1750 can support up to 48MB DRAM max.

DRAM normally is 16MB, 32MB and 64MB, no 48MB.

1750-2/4V with IP/Voice+ IOS 12.1(5)YB1 need 48MB DRAM.

What P/N of RAM should I purchase?

How can I make my 1750 be 48MB DRAM to run this IOS?

The 1750 is supplied with 16mb of DRAM on the motherboard. Add a 32mb DRAM SIMM and you get 48MB. The part number is MEM1700-32D
