Table 1-1	Cisco 7600 Series Routers Key Features (continued)
Feature	Description
Memory	• Electrically erasable programmable read-only memory (EEPROM) on the
components	supervisor engine or route switch processor stores module-specific
	information, such as the serial number, part number, controller type,
	hardware revision, configuration information, and other details unique to
	each module.
	• NVRAM for storing configuration information.
	• DRAM for default system software.
	• Internal flash memory—To store the boot image. The defaults are:
	• The RSP720 SP/RP and the Sup32 SP contain a CompactFlash (CF)
		adapter that provides 512 MB of internal flash memory.
	• The Sup720 SP/RP, Sup32 RP, and Sup2 SP/RP contain 32-MB or
		64-MB of internal flash memory. Cisco IOS Release 12.2(18)SXF and
		later releases support the CF adapter as an orderable option (Cisco part
		number CF-ADAPTER=) for these Sups. 1
	Note In the command-line-interface (CLI), you access internal flash memory
		as bootdisk (CF adapter) or bootflash (non-CF adatper). When you
		install a CF adapter on the Sup720, Sup32, or Sup2, bootflash becomes
		an alias to bootdisk.
	• External flash memory—To store and run software images and configuration
	files or to serve as an input/output (I/O) device. You can install 64-MB,
	128-MB, 256-MB, or 512-MB flash memory cards, or 1-GB MicroDrive card,
	in slots on the supervisor engine or RSP front panel.
	The Sup2 supports PCMCIA flash memory cards only. It does not support
	CompactFlash or MicroDrive cards.
	• Flash file system—Flash memory contains a file system. You can use a
	variety of commands to manage the file system (such as cd, pwd, dir, and
	delete). The file system includes the following devices:
	–	Onboard bootflash/bootdisk
	–	Flash memory slot
Component hot	All components (including optional redundant modules and fans) support hot
swapping	swapping, which allows you to add, replace, or remove components without
	interrupting the system power or causing other software or interfaces to shut down.
Management	• CLI through the console port or Telnet

•Simple Network Management Protocol (SNMP)
