How to add the memory of mid-range routers using 8240CPU such as R262×, R263×E and R36××E?
1. All R3680E, R3640E, R2631E and R2630E have two memory slots. When only the first (near to CPU) is used, 32M, 64M and 128M are permitted; but in expansion of memory, the first slot must insert a memory of 128M, and the combination is as follows:
slot 1 slot 2
2. R2620 and R2621 have only one memory slot respectively, supporting 32M, 64M and 128M.
3. By default, R36××E is 128M memory; R263×E is 64M memory, and R262× is 32M memory.
