Memory Components - Cisco RSP1 Installation And Configuration Manual

What Is the RSP1?

Memory Components

Figure 2 shows the various types of memory components on the RSP1, and Table 1 lists the
functions of each type.

Type Size
DRAM 16 to 128 MB
NVRAM 128 KB
Flash SIMM 8 MB
Flash Card 8, 16, and 20 MB
Boot ROM 256 KB
1. A system configuration file is contained in NVRAM, which allows the software to control several system variables.
2. Only Intel Series 2 Flash memory cards can be used with the RSP1.
System Software
The Cisco 7505 router supports downloadable system software and microcode for most Cisco IOS
and microcode upgrades, which enables you to remotely download, store, and boot from a new
image. The publication Upgrading Software and Microcode in Cisco 7XXX Series Routers
(Document Number 78-1144-xx), which accompanies all Cisco IOS upgrade kits, 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, then decompresses the images into running dynamic random-access
memory (DRAM). The bundled microcode images then function the same as the EPROM images.
