Hi, I would like to upgrade DRAM 512MB to 1 GB in Cisco 3845. Without shutdown how to know whether DRAM placed in one or two DIMMS or SIMMS.
from the cli type "sh tech-support" you will see something like:-
Dimm 0 SPD data :
Size of dimm = 256 Megabytes
Memory Type = 0x7
There is a lot of data from the output, I suggest you log it to a text file, then search for it.
