sdram dimm configuration on 3660

Hi, is there any method of determining the sdram dimm hardware configuration on a 3660 without opening the actual router ?

Re: sdram dimm configuration on 3660

check "sh version" and it will tell you how much DRAM you have.

Re: sdram dimm configuration on 3660

I actually need the physical configuration - how many simms and simm memory size - 2 x 8mb or 1 x 32 etc.

Sorry, no way !

The command "show c2600" exists on 2600 router platforms and shows the memory slots being used. This command on the 3600 platform "show c3600" does not show the same.

If you take a look in this link (http://www.cisco.com/warp/customer/cc/pd/rt/3600/prodlit/544_pp.htm) you can see:

"The 32 MB DRAM memory default is available on all new system orders placed after October 26th, 1998 on the following feature sets including: 11.1A, 11.2P, 11.3, 11.3T, 12.0, and 12.0T. There will be no additional charge for this memory increase."

I think this is a only 32 Mb DIMM in slot 0, but I have purchased some 3660 after 1998 and came to me with differents configurations of memory.

But if you have in your "sh ver" 32 Mb, is very possible that you have just one DIMM in slot 0

The only way to ensure is open !

many thanks

Re: sdram dimm configuration on 3660

Hopefully this should work on 3660 also.

Sorry, the above link, does not work for a 3660.

Re: sdram dimm configuration on 3660

Hi,

Hope this might help you. Can you issue the 'sh pci controller' command and review the following output information. This procedure is not documented but may be it works.

'show pci controller' and parse the output as below to
