may print a message on the console port reporting a checksum error. If this happens, locate the
EPROM that might be incorrectly inserted, remove it, straighten pins as required, then reinsert the
EPROM and restart the system. If an EPROM is inserted backwards and power is turned ON, the
EPROM is damaged and requires replacement.

Replacing RP SIMMs (Upgrading DRAM)

The system DRAM resides on four single inline memory modules (SIMMs) on the RP. The default
DRAM configuration is 16 MB (four 4 MB x 9 SIMMs). This section provides the steps for
increasing the amount of DRAM from 16 MB to 64 MB by replacing the four 4 MB SIMMs with
four 16 MB SIMMs that you obtain from an approved vendor. Some (earlier) RPs do not support
16 MB SIMMs; before upgrading, use the prerequisites in the following section to ensure that your
RP will support the larger SIMMs. You must use SIMMs that you obtain from an approved vendor;
otherwise, Cisco Systems cannot ensure proper operation.
Compatibility Requirements
Before replacing SIMMs to increase the amount of DRAM available in your system, ensure that your
RP supports 16 MB SIMMs and that you obtain the replacement SIMMs from an approved vendor.
Only RPs that meet the following prerequisites support the larger (16 MB) SIMMs:
•
If your system contains Software Release 9.17, the minimum requirements are:
— System Software Release 9.17(8) (or a later 9.17 image) in ROM
— System Bootstrap Version 4.6(7.3) (or a later 4.6 bootstrap version)
— RP board revision B0 or later
•
If your system contains Software Release 9.21, the minimum requirements are:
— System Software Release 9.21(3) (or a later 9.21 image) in ROM
— System Bootstrap Version 4.7(2.1) (or a later 4.7 bootstrap version)
— RP board revision B0 or later
Bootstrap Version 4.6 is used exclusively with Software Release 9.17, and Bootstrap Version 4.7 is
used exclusively with Software Release 9.21. The revision numbers (indicated within parentheses)
for each version are revised independently of other bootstrap versions. Therefore, 4.6(7) can be a
later version than 4.7(2).
If you installed ROMs of a different capacity than those that were previously installed,
check Figure 5-8 and reset jumpers J3 or J4 if necessary (notification of a new ROM size
will be included with the replacement EPROMs if applicable).
Follow the Steps in the section "Installing CxBus Interface Processors" to reinstall the RP.
Be sure to use the ejector levers to install the RP, then tighten the top and bottom captive
installation screws.
Reconnect any console or auxiliary port cables to the connectors on the RP.
Turn ON the system for an installation check, which is described in "Starting the Router"
in the chapter "Installing the Router."
If you power up a system when one or more of the EPROMs is incorrectly inserted, the system
