Field-Replaceable Units Chapter 1 Cisco 7200 VXR Product Overview Table 1-10 NPE-300 Memory Specifications (continued) Memory Type Size Quantity Description Location1 Secondary 256 KB - cache RM7000 processor, internal, U49 unified instruction and data cache Tertiary cache 2 MB (fixed) - RM7000 processor, external cache U7, U8, U9, U10, U17 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.

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. 1-22 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
