Installing and Configuring Processor Modules
This section describes the steps for increasing the amount of DRAM by replacing up to four SIMMs .
Figure 5-12
The SIMM sockets use the thumb tabs that are often used in PCs and other computer equipment.
Each RSP7000 SIMM socket has two metal retaining springs, one at each end. (See Figure 5-13.)
When a SIMM is fully seated in the socket, the retaining springs snap over the ends of the SIMM to
lock it in the socket.
