Replacing Rsp7000 Dram Simms - Cisco 7000 Hardware Installation And Maintenance

Installing and Configuring Processor Modules
This completes the SIMM replacement procedure.
Proceed to the section "Removing and Replacing the RP, SP or SSP, RSP7000, or RSP7000CI" to
replace the RSP7000 in the chassis and restart the system for an installation check. Note that the
RSP7000 does not support OIR
If the system fails to boot properly, or if the console terminal displays a checksum or memory error,
check the following:
•
•
If after several attempts the system fails to restart properly, contact a service representative for
assistance. Before you call, make note of any error messages, unusual LED states, or any other
indications that might help solve the problem.
Note
Routers with 128 MB of DRAM will take longer to boot than those with 16 MB of DRAM.\

Replacing RSP7000 DRAM SIMMs

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 5-15.)
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.
This section describes the steps for increasing the amount of DRAM by replacing up to four SIMMs
that you obtain from an approved vendor.
5-200 Cisco 7000 Hardware Installation and Maintenance
Ensure that all SIMMs are installed correctly. If necessary, shut down the system and remove the
RSP7000. Check the SIMMs by looking straight down on them and then inspecting them at eye
level. The SIMMs should all be aligned at the same angle and the same height when properly
installed. If a SIMM appears to stick out or rest in the socket at a different angle from the others,
remove the SIMM and reinsert it. Then replace the RSP7000 and reboot the system for another
installation check.
Each DRAM SIMM bank must contain SIMMs of the same size and speed or the system will not
operate. SIMMs must be 60 ns or faster. The speed is printed along one edge of the SIMM.
The time required for the system to initialize varies with different router configurations.
The total number of memory devices per SIMM differs for each manufacturer. The SIMMs
