Installing the NPE-G1 or NPE-G2 Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information Upgrading the SDRAM SODIMMs on the NPE-G1 (Optional) If you have purchased an SDRAM memory upgrade for the NPE-G1, replace the SDRAM SODIMMs on the NPE-G1 using the following instructions. Removing a SODIMM Step 1 Locate the SODIMMs on the NPE-G1. Figure 7-14 Locating the SODIMMs on the NPE-G1 2 1 GIGABIT ETHERNET 0/1 LINK EN RJ45 RX GBIC TX GIGABIT ETHERNET 0/1 LINK EN RJ45 RX GBIC TX GIGABIT ETHERNET 0/1 LINK EN RJ45 RX GBIC TX NETWORK PROCESSING ENGINE - G1 CPU RESET C O M PAC T F L A S H SLOT ACTIVE POWER ON CONSOLE AUX 66948 1 SODIMM 2 2 SODIMM 1 Note Both SODIMMs must be of the same size and type, and both SODIMM sockets must be populated. Step 2 Remove the SODIMM you want to replace by pulling outward on the SODIMM spring latches with your thumbs. The SODIMM springs up to allow you to easily pull it from the socket. 7-26 Network Processing Engine and Network Services Engine Installation and Configuration OL-4448-12
