Installation Prerequisites
Flash Memory Card Replacement and Formatting Prerequisites
If you have a Flash memory card installed in the PCMCIA slot of your RP, you must reformat it if
you want to use it with your new RSP7000. Using the RSP7000, you cannot read data on the RP's
Flash memory card, nor can you use it as bootable media. You must reformat the RP's Flash card on
the RSP7000 before you can use it with the RSP7000. Flash memory cards formatted on the
RP-based systems (7000 series routers) are formatted differently from Flash memory cards
formatted on RSP-based systems (7500 series routers or 7000 series routers equipped with an
RSP7000).
Caution
loss of important data that might be stored on a Flash memory card, proceed carefully. If you want
to save the data on a Flash memory card, copy the data to a server before you format the card.
Saving and Retrieving the Configuration File
This section describes the procedures for saving and retrieving the system configuration.
Configuration information resides in two places when the router is operating: the default
(permanent) configuration in NVRAM, and the running (temporary) memory in RAM. The default
configuration always remains available; NVRAM retains the information even when the power is
shut down. The current information is lost when if the system power is shut down. The current
configuration contains all nondefault configuration information that you added with the configure
command, the setup command facility, or by editing the configuration file.
The copy running-config startup-config command adds the current configuration to the default
configuration in NVRAM, so that it will also be saved when power is shut down. Whenever you
make changes to the system configuration, issue the copy running-config startup-config command
to ensure that the new configuration is saved.
If you replace the RSP7000, you will also replace the entire configuration (NVRAM resides in
socket U17 on the RSP7000). If you upload (copy) the configuration file to a remote server before
removing the RSP7000, you can retrieve it later and write it into NVRAM on the new RSP7000. If
you do not upload the configuration file, you will have to use the configure command or the setup
command facility to reenter the configuration information after you install the new RSP7000. For
complete descriptions of these commands and instructions for using them, refer to the appropriate
software documentation.
This procedure is not necessary if you are temporarily removing an RSP7000 that you will reinstall;
the lithium batteries will retain the configuration in memory until you replace the RSP7000 in the
system.
This procedure requires privileged-level access to the EXEC command interpreter, which usually
requires a password. Refer to the description that follows and contact your system administrator if
necessary, to obtain access.
