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.

Upgrading, Configuration, and Troubleshooting Tasks

Using the show version Command

Router(config)#

boot

bootldr bootdisk:c7300-boot-mz-my-image

Router(config)#

copy system: running-config nvram: startup-config

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:

ROMMON>

set

bootldr

is not set correctly, set it with the correct image:

ROMMON>

BOOTLDR=”bootdisk:c7300-boot-mz-my-image”

Caution

Be careful of typographical errors in ROMmon mode as there is no error checking.

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

router:
