Field-Replaceable Units Chapter 1 Product Overview Table 1-2 Network Processing Engine Memory Specifications (NPE-100, NPE-150, and NPE-200) Memory Type Size Quantity Description Location DRAM 32 to 128 MB 2 to 4 16- or 32-MB SIMMs (based on maximum DRAM required) Bank 0: U18 and U25 or U11 and U251 Bank 1: U4 and U12 or U42 and U522 SRAM NPE-150 1 MB 8 8 chips, each being 128K words x 9 bits wide U700 through U703 U800 through U803 NPE-200 4 MB 8 Boot ROM3 8 chips, each being 512K words x 8 bits wide U6, U10, U13, U14, U28, U29, U38, and U39 NPE-200 256 KB 1 EPROM for the ROM monitor U92 program Primary cache - - R4700 processor, internal NPE-100, cache NPE-150: U201 R5000 processor, internal cache NPE-200: U44 Secondary 512 KB 4 cache R4700, unified external cache NPE-100 and NPE-150: U2, U10, U14, and U26 R5000, unified external cache NPE-200: U16, U9, U109, and U107 1. The sockets for bank 0 on the NPE-100 and the NPE-150 are numbered U18 and U25. The same sockets on the NPE-200 are numbered U11 and U25. 2. The sockets for bank 1 on the NPE-100 and the NPE-150 are numbered U4 and U12. The same sockets on the NPE-200 are numbered U42 and U52. 3. ROM = read-only memory. The NPE-100 and NPE-150 use the boot ROM present on the I/O controller. Note To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that your system initializes correctly at startup, DRAM bank 0 (socket U18 and U25, or U11 and U25) must contain no fewer than two SIMMs of the same type. You may also install two SIMMs of the same type in bank 1 (socket U4 and U12, or U42 and U52); however, bank 0 must always contain the two largest SIMMs. Table 1-3 lists the NPE-175 and NPE-225 memory specifications.
