Before proceeding, ensure that you have the proper tools and ESD-prevention equipment available.
To upgrade DRAM, you install SIMMs in one or two banks. Table 5-9 lists the various
configurations of DRAM SIMMs that are available. Note which banks are used given the
combinations of available SIMM sizes and the maximum DRAM you require. SIMMs must be 60 ns
or faster and no taller than one inch.
Depending on your router configuration, Cisco IOS Release 11.1(1) might require more than
Note
16 MB of DRAM for your RSP7000. Upgrade your system DRAM based on your current
configuration and this potential requirement.

1. The 24-MB DRAM configuration is also available as an 8-MB upgrade to the standard 16-MB configuration, by adding
DRAM-Product Number MEM-RSP-8M= (consisting of two, 4-MB DRAM SIMMs), for a total of 24 MB.
To prevent DRAM errors, each DRAM bank used must contain no less than two SIMMs

of the same type. You must install either two SIMMs in bank 0 or four SIMMs in two banks.
Removing SIMMs
Place removed SIMMs on an antistatic mat and store them in an antistatic bag. You can use the
SIMMs that you remove in compatible equipment.
Caution To prevent ESD damage, handle SIMMs by the card edges only.
Follow these steps to remove the existing SIMMs:
Turn OFF the system power and follow the steps in the section "Removing and Replacing
Step 1
the RP, SP or SSP, RSP7000, or RSP7000CI." Note that the RSP7000 does not support
OIR.
Step 2 Place the RSP7000 on an antistatic mat or pad, and ensure that you are wearing an antistatic
device, such as a wrist strap. Position the RSP7000 so that the handle is away from you, and
the edge connector is toward you; opposite of the position shown in Figure 5-12.
Locate SIMMs. The DRAM SIMMs occupy U4 and U12 in bank 0, and U18 and U25 in
Step 3
bank 1. (See Figure 5-12.)
