Does anyone know if cisco 1861 CME router (aka UC500) can run c1861-advipservicesk9-mz.15+ code?
Cisco say: Minimum Memory: DRAM:384 MB Flash:128 MB
It also says that the Maximum memory is 256MB (http://www.cisco.com/en/US/prod/collateral/routers/ps5853/ps8321/prod_qas0900aecd806c4def.html)
I tried running IOS 15, but the router keeps crashing. I suspect it is because I only have 256Mb memory. There is a DRAM slot available onboard, but I could not find any information on 1861 DRAM memory upgrade.
