Use flash memory to store multiple Cisco IOS software and microcode images
that you can use to operate the router. You can download new images to flash
memory over the network (or from a local server) to replace an existing image, or
to add it as an additional image. The router can be booted (manually or
automatically) from any of the stored images in flash memory.
Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server that
allows other servers to boot remotely from the stored images, or to copy them into
their own flash memory.
The system uses two types of flash memory:
Onboard flash memory (called bootflash)—Contains the Cisco IOS boot
•
image.
20 MB Type II PCMCIA flash memory cards (MEM-GRP-FL20=)—Contain
•
Cisco IOS software images.
The performance route processor (PRP) uses a Motorola PowerPC 7450 CPU that
runs at an external bus clock speed of 133 MHz and has an internal clock speed
of 667 MHz.
Figure 1-14 identifies the slots, ports, and LEDs on the PRP front panel.
