Cisco 3640 router problem ?
Hello technical expert,
I have Cisco 3640 router that have 16MB flash memory and 48MB DRAM memory. I want to install a NM-ESW-16 16 ports network module in my router. I used Software Advisor of CISCO web site and that told me minimum Software Image c3640-i-mz.123-23, Minimum DRAM 50, Minimum Flash6 16. My router’s DRAM is smeller than requirement. But I copied 12.3-23 IOS and my router boots it without any problems. But there is not my 16 ports nm in show run command result.
Why I can’t see my 16 ports? Is it from DRAM ?
Yes, you don't have enough memory to recognize the module is the likeliest cause.
