Reference Information

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 4 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.

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.

Caution

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

Follow these steps to remove the existing SIMMs:

To prevent DRAM errors, each DRAM bank used must contain no less than two SIMMs

To prevent ESD damage, handle SIMMs by the card edges only.

Turn OFF the system power and follow the steps in the section "Removing the RSP7000"

on page 18.

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 3 on page 5.

Locate SIMMs. The DRAM SIMMs occupy U4 and U12 in bank 0, and U18 and U25 in

bank 1. (See Figure 3.)
