Failure To Boot After A Sdram Upgrade Or Replacement; Using The Show Version Command - Cisco 7304 Installation And Configuration Manual

Chapter 7 Upgrading, Configuration, and Troubleshooting Tasks
The show bootvar command can be used in ROMmon mode to verify that parameter settings are correct.
In cases where the system will not boot up, you can also use the bootldr command in ROMmon mode.
First check to see if bootldr is set correctly:
If bootldr is not set correctly, set it with the correct image:
Be careful of typographical errors in ROMmon mode as there is no error checking.
Caution
You can use the ROMmon command sync to save the current parameters that remain after a power cycle
to NVRAM.
Use the set command to check your configuration.

Failure to Boot After a SDRAM Upgrade or Replacement

Note Only the NSE-100 uses SDRAM SODIMMs. The NSE-150 DDR-SODIMMs are not field-upgradeable.
If, after a SDRAM upgrade or replacement, the system fails to boot properly, or if the console terminal
displays a checksum or memory error, ensure that the SODIMM is installed correctly. If necessary, shut
down the system and remove the network services engine. Check the SODIMM by looking straight down
on it and then at eye level. If the SODIMM appears to stick out or rest in the socket at an odd angle,
remove it and reinsert it. Then replace the network services engine and reboot the system for another
installation check.
If after several attempts the system fails to restart properly, contact a service representative for
assistance. Before you call, note any error messages, unusual LED states, or other indications that might
help solve the problem.

Using the show version Command

Use the show version command to display the configuration of the system hardware including the NSE
and the software version.
The following example of the show version command identifies an NSE-100 installed in a Cisco 7304
