Hi all,
I have a strange one for you guys and would appreciate any ideas you may
have.
I have a Cisco 3640 router that is operating normally. It is however using
IOS 11.1 and we have bought memory to upgrade this (sho ver below) . We
install the DRAM and all is great. Install the flash and the router fails to
boot. I don't have any log messages, but the remote support guy says that it
(router console) says there is no flash installed in the router. Since this
happened previously, we tried another 2 separate 3640 chassis', and this
flash memory worked great. Now this leads me to believe there is something
wrong with the motherboard on the router. Strangely enough another reboot of
the router and everything comes up with the exception of the Token Ring
interface - a further look here reports an error about wrong ring number.
Nothing has changed at all here. Another reload and the flash vanishes.
Reinstall the old flash memory and router is operational again.
I know this memory works - used other routers. The ring number error has me
totally confused. Upgrades to all other exactly configure sites worked
perfectly
New flash module is 16MB and old is 4MB
