I have a GB AIM CUE card that I have installed into my 2621XM. The router is running IOS 12.3(17a) with 128 MB RAM and 48 MB flash. During POST, the service engine AIM is recognized during the memory checks (see capture)
Smart Init is enabled

ID MEMORY_REQ TYPE
00036D 0X00103980 C2621XM Dual Fast Ethernet
00038E 0X0004FE00 Service Engine AIM
0X00098670 public buffer pools
0X00211000 public particle pools
but after complete boot, the service engien does not appear in a sh version, sh diag, or sh run.
I pulled the AIM CUE card out of my 2621 and installed it into my 3725. Router booted and I saw and was able to configure the service engine - so the problem is not the card.
I tried a different 2621 with the same results.
Full POST, sh version, sh diag, and sh run are attached
Good morning Jeffrey,
The compatibility matrix for CUE lists 12.3(7)T as the minimum version for the 2600XM series of routers. So it seems you could either run any of the later 12.3T images or go up to 12.4.
Hope this helps,
