Q: How to extend the memory of mid-range routers that use 8240CPU like R262X, R263XE and R36XXE?
A: 1. There are two memory slots on the R3680E/R3640E/R2631E/R2630E. When the first slot (close to the CPU) is used only, the memory can be 32M, 64M or 128M. When the memory is extended, a memory bar of 128M must be inserted in the first memory slot.
Optional combinations are as follows:
Slot 1 Slot 2
2. There is only one memory slot on the R2620/R2621, supporting 32M, 64M and 128M.
3. By default, the R36XXE uses the memory of 128M; the R263XE uses the memory of 64M; the R262X uses the memory of 32M.
