Maintaining and Upgrading the Router 5-17
Memory Replacement Procedures
Installing Flash-Memory SIMMs
You upgrade boot helper Flash memory by replacing the existing SIMM (labeled System Flash
Memory 0), or by adding a second SIMM to the empty socket (labeled System Flash Memory 1).
Take the following steps to add Flash-memory SIMMs:
Step 1
On the motherboard, locate the Flash-memory SIMM sockets shown in Figure 5-5 and
Figure 5-6.
Caution
Handle SIMMs by the edges only. SIMMs are ESD-sensitive components and can be
damaged by mishandling.
Step 2
Hold the SIMM with the polarization notch on the right and the component side away from
you with the connector edge at the bottom.
Step 3
Referring to Figure 5-12, insert the Flash-memory SIMM at a 45-degree angle and rock it
into its vertical position. (See Figure 5-5 and Figure 5-6.) When the SIMM is properly
seated, the socket guide posts will insert through the alignment holes, and the locking
springs will click into place. Use the minimum amount of force required.
