Cisco RSP1 Installation And Configuration Manual page 9

New microcode is released to enable new features, improve performance, or fix bugs in earlier
versions. The Cisco routers feature downloadable software and microcode for most upgrades. These
features enable you to download new (upgraded) images remotely, store the images in router
memory, and load the new images at system startup without having to physically access the router.
You can store multiple versions for a specific processor type in Flash memory and use configuration
commands to specify which version the system should load at startup. All interfaces of the same type
(for example, all CIPs) use the same microcode image. Although most upgrades can be downloaded,
some exceptions require ROM replacement to ensure proper startup and operation. Microcode
images that are bundled with the system image load automatically along with the new software
image.
Note
to work together. Overriding the bundle can result in incompatibility between the various interface
processors in the system. We recommend that you use only the microcode image that is bundled. The
exception to this is CIP microcode, which as of Cisco IOS Release 11.1(1) is unbundled from the
Cisco IOS image bundle, and is available in a separate bundle on floppy disks, a TFTP server, from
CIO, or on Flash memory cards.
List of Tools and Parts
You need some or all of the following tools and parts to remove and replace an RSP1. If you need
additional equipment, contact a customer service representative for ordering information.
•
Number 2 Phillips or 1/4-inch, flat-blade screwdriver for the captive installation screws that
secure the RSP1 in its slot.
•
ESD-prevention equipment or the disposable ESD-preventive wrist strap included with all spares
and upgrade kits.
•
Antistatic mat, foam pad, or bag for the removed RSP1 (place the removed RSP1 into an
antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are
replacing components and will reinstall the RSP1)
•
If you are replacing SIMMs, you will need 60-ns SIMMs from an approved vendor.
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 RSP1, you will also replace the entire configuration (NVRAM resides in socket
U17 on the RSP1). If you upload (copy) the configuration file to a remote server before removing
the RSP1, you can retrieve it later and write it into NVRAM on the new RSP1. If you do not upload
The software and interface processor microcode images are carefully optimized and bundled
