I need to upgrade RAM in a few Cisco 2651xm routers that I don't currently have physical access to.  Is there an IOS command that will show how many RAM slots are in use without having to take the cover off and visually inspect the motherboard?

just check the total amount of ram and then divide it by the size of each stick.

Thanks, but my question is how can I tell how many sticks are in the router in the first place?

by doing that, view the total and then divide by the size of each stick and you will get the amount of sticks.

It shows total amount of RAM, but not whether that is one stick or two.  For example, if I have a total of 64 MB of RAM, is it installed as one 64 MB stick or two 32 MB sticks?

On a PC, there is diagnostic software available that will tell you how many memory slots are on the motherboard and how many of these slots are utilized.  I'm looking for the same information for a router.

kf4zmt,

No, I've never run across a command that can perform a query on RAM Slots. The 2650x has two RAM slots. The routers I've ordered from Cisco with 32 64 or 128 have used one slot. Obviously if you have  some  96 MB, 160 MB, 192 MB, 256 MB your using 2 slots. My experience.

Have you tried to contact Cisco support?
They should be able to provide[or to tell you how to get ] the information about your hardware.

I've asked some colleagues and they believe its a physical only operation... i.e check under the hood :)
