Upgrade DRAM on Cisco ISR 4451

[bella.nurhasanah]

Hi,

I want to ask about upgrade DRAM on Cisco ISR 4451, is it possible if I want to upgrade the DRAM (before 4G) to 16G? Is there any association with Flash Memory? Because I have a note when I want to upgrade the DRAM.

Thanks and Regards,

Bella

Hi @bella.nurhasanah

According to Cisco doc, you can upgrade to 8 GB:

Platform	Part number	Description
Cisco 4400 Series Routers (4451 and 4431)	MEM-4400-2G=	2G DRAM (1 DIMM) for Cisco ISR 4400, Control Plane or Data Plane, Spare
	MEM-4400-4G=	4G DRAM (1 DIMM) for Cisco ISR 4400, Spare
	MEM-4400-8G=	8G DRAM (1 DIMM) for Cisco ISR 4400, Spare

So can you just buy the memory from Newegg or such? I don't want to cause a problem with my SmartNet coverage, but I don't see an easy path to buying the DRAM.
