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.
•Ifthe system fails to boot properly, if the console terminal displays a checksum or memory error, or
ifthe show diag command output indicates an incorrect amount of memory (or no memory), check
the following:
–
Ensure that all memory devicesare installed correctly. If necessary, shut down the system and
removethe 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 deviceappears 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 severalattempts 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 anyother indications that might help solve the problem.
Thetime 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 keyto 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 startup-configuration command to display the enable password.
•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 Step11), instead of rebooting it.
