Replacing and Upgrading DRAM SIMMs

This section describes the steps for increasing the amount of DRAM by replacing up to four SIMMs

that you obtain from an approved vendor. The system DRAM resides on up to four SIMMs on the

RSP7000. The DRAM SIMM sockets are U4 and U12 for Bank 0, and U18 and U25 for Bank 1.

The default DRAM conﬁguration is 16 MB (two 8-MB SIMMs in Bank 0). (See Figure 6.)

Note

in the following illustrations are generic representations of the actual DRAM SIMMs for your

RSP7000. To be sure that you are using the correct SIMMs, refer to the speciﬁc part or product

numbers indicated in the approved vendor list (AVL) and by your DRAM upgrade requirements.

Figure 6

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 7 on

page 31.) 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.
