System Software

The Cisco 7505, Cisco 7507, and Cisco 7513 routers support downloadable system software and
microcode for most Cisco IOS software and microcode upgrades. This enables you to remotely
download, store, and boot from a new image. The publication Upgrading Software and Microcode in
Cisco 7000 Series and Cisco 7500 Series Routers (DOC- 781144=) provides instructions for upgrading
over the network or from floppy disks.
Flash memory contains the default system software. An erasable programmable read-only memory
(EPROM) device contains the latest microcode version, in compressed form, for each interface
processor.
At system startup, an internal system utility scans for compatibility problems between the installed
interface processor types and the bundled microcode images. The utility then decompresses the images
into running dynamic random-access memory (DRAM). The bundled microcode images then function
the same as the EPROM images.
The Cisco IOS software images reside in Flash memory, which is located on the RSP2 in the form of a
single in-line memory module (SIMM), on Flash memory cards that insert in the two PC Card slots
(slot 0 and slot 1) on the front of the RSP2. (See
memory enables you to download and boot from upgraded Cisco IOS images remotely or from software
images resident in the RSP2 Flash memory.
Although no monitoring of voltage or temperature is done by the RSP2, a comparator device ensures that
voltage is within the normal operating ranges, and three temperature sensors on the RSP2 send
temperature information to the chassis interface (CI) card. The CI card reports all voltage and
temperature readings, and these readings are available through standard software commands for
environmental monitoring. The RSP2 uses a software-controlled configuration register, so you do not
have to remove the RSP2 to configure jumpers. There are no user-configurable jumpers on the RSP2.
The exception to this is CIP microcode, which, as of Cisco IOS Release 11.1(1), is unbundled from the
Note
Cisco IOS software image bundle, and is available in a separate bundle on floppy disks, a TFTP server,
Cisco.com, or PC Card-based Flash memory media.

Installation Prerequisites

Before beginning the installation procedures, review the following sections to ensure awareness of the
appropriate regulatory and safety requirements, and to ensure that your RSP2 hardware functions
properly with compatible components:
•
•
Note If you are replacing an existing RSP2, back up your current configuration file to a remote server before
you remove the RSP2 to avoid having to reenter all your current configuration information manually. To
back up the file, you need access to a remote server. For instructions for uploading the file and retrieving
it after the new RSP2 is installed, see the
