Step 8 When the DIMM is installed, check that the release lever is flush against the side of the DIMM socket. If it is not, the DIMM might not be seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until the release lever is flush against the side of the DIMM socket.

Caution When inserting DIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the GRP to the factory for repair.

Step 9 Repeat Step 4 through Step 8 for the remaining DIMM, as required.

Checking the DIMM Installation

After you install the new DIMMs and replace the GRP, turn on system power and allow the system to reboot.

Note The time required for the system to initialize might vary with different router configurations and DRAM configurations. Routers with 256 MB or more of DRAM might take longer to boot than those with less DRAM.

If the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:

•Ensure that all DIMMs are installed correctly. If necessary, shut down the system and remove the GRP to check the DIMMs. Look straight down on the DIMMs to inspect them at eye level. They all should be aligned at the same angle and the same height when properly installed. If a DIMM appears to stick out or rest in the socket at a different angle from the others, remove the DIMM and reinsert it. Then replace the GRP and reboot the system for another installation check.

•DIMMs must be extended data output (EDO), +3.3VDC, 60-ns DRAM devices. The speed is printed along one edge of the DIMM.

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.
