Component Description
CPU (NPE200) Central processing unit.
Processor memory The Cisco IOS image is initially read out of Flash
memory, decompressed, and loaded into processor
memory (also known as main memory).
Routing tables, call control blocks, and other data
structures are also stored here.
Packet I/O memory Packets are temporarily stored in I/O memory.
slot0: flash:
PCMCIA Flash memory cards. Stores Cisco IOS
images, modem firmware/portware, and custom web
slot1:
pages.
bootflash: Flash memory on the Cisco 7206 s motherboard.
nvram: Non-volatile configuration memory.
dsc12-slot0:
PCMCIA Flash memory cards. Flash memory in the
DSC.
dsc12-slot1:
dsc12-bootflash: Flash memory on DSC s motherboard.
dsc12-nvram: Non-volatile configuration memory in the DSC.

" Inspect the Flash memory on the router shelf and dial shelf. Both images must have a matching
Cisco IOS Release number. In this example, both images are from Release 12.0(4)XL1. As the
chassis boots up, the images are copied, decompressed, and loaded into DRAM memory.
