1.Location on processing engine board. See Figure 1-9.

2.Bank 0 is used exclusively for packet memory and is not user configurable.

3.Bank 1 contains the Cisco IOS software, processor memory, and packet memory.

4.OTP = one-time programmable

Note The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet memory requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed configuration in the factory.

Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3 (see Figure 1-9). Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM in slot 3 can be zero.

1.There are two user-upgradable SDRAM slots in bank 1. (Bank 0 is used exclusively for packet memory and is set at a fixed configuration in the factory.)

2.These products are also available as SDRAM upgrades. To order an upgrade, add an equal sign (=) after the product number, for example, MEM-SD-NPE-128MB=.

3.This 32 MB is fixed memory in SDRAM bank 0, socket U16. Socket U15 is never populated.
