Checking the RSP Memory Upgrade
This section describes how you would verify the memory upgrade.
•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 DIMM socket must contain a DIMM 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.
If after several attempts the system fails to restart properly, contact TAC (see the “Obtaining Technical Assistance” section on page 89 ), or 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. The time required for the system to initialize might vary with different router configurations and DRAM configurations. Routers with 256 MB of DRAM might take longer to boot than those with less DRAM.
This completes the RSP memory upgrade verification.
Recovering a Lost Password
An overview of the procedure for recovering a lost password follows:
•Use the show version command to note the existing software configuration register value.
•Break to the bootstrap program prompt.
•Change the configuration register to ignore NVRAM.
Note A key to recovering a lost password is to set the configuration register so that the contents of NVRAM are ignored (0x0040), allowing you to see your password.
•Enter privileged level in the system EXEC.
•Use the show
•Change the configuration register value back to its original setting. If the enable password is encrypted, the following procedure does not work for password recovery and you must reconfigure the router using the displayed configuration (shown in Step 11), instead of rebooting it.
