Hold the SIMM between your thumbs and forefingers. (See
Step 2
The SIMM should be facing component-side down.
Note
Insert the connector edge of the SIMM straight into the socket.
Step 3
When inserting the SIMM, use firm but not excessive pressure. If you damage a socket, you will have to

return the RSP to the factory for repair.
Step 4 Gently push the SIMM into the socket until the socket release levers close over the ends of the SIMM.

Step 5 Check to see if the SIMM is seated properly. If the SIMM appears misaligned, carefully remove it and
reseat it in the socket. Push the SIMM firmly back into the socket until first one and then the other socket
release lever moves into place.

This completes the procedure for installing DRAM SIMMs. Proceed to the following section to check
the installation.
Checking the RSP Memory Upgrade
This section describes how you would verify the memory upgrade.

of any error messages, unusual LED states, or any other indications that might help solve the problem.
The time required for the system to initialize might vary with different router configurations and DRAM
configurations. Routers with 128 MB of DRAM might take longer to boot than those with less

Figure 14.) If necessary, rock the SIMM gently back and forth to seat it properly.
Step 1 through Step 5 above if you are replacing more than one SIMM.
Observe the LED states and the console display. As the system reinitializes the interfaces, the
enabled LEDs should go on. (Port adapter status LEDs might be on, depending on your
connections.) The console screen also displays a message as the system discovers each interface
during its reinitialization.
Use the show diag command to verify that the system recognizes the new memory; check the line
of the show diag command output that begins with Controller Memory Size.
If the system fails to boot properly, if the console terminal displays a checksum or memory error, or
if the show diag command output indicates an incorrect amount of memory (or no memory), check
the following:
– Ensure that all memory devices are installed correctly. If necessary, shut down the system and
remove the RSP. Check the memory devices by looking straight down on them and then at eye
level. The devices should be aligned at the same angle and the same height when properly
installed. If a memory device appears to stick out or rest in the socket at a different angle from
the others, remove the device and reinsert it; then replace the RSP and reboot the system for
another installation check.
Each SIMM socket must contain a SIMM of the correct size and speed or the system cannot

operate. To ensure this, use only memory devices that are included with Cisco Systems memory
kits.
