Chapter 3 Installing the Router

IOS Software Configuration for the Router

Table 3-11	Cisco IOS Software Image Sources
Onboard Flash Memory		The latest Cisco IOS software image is loaded into the
on the Gigabit Route		Flash memory, a single inline memory module (SIMM)
Processor (GRP)		that is preloaded at the factory before the router is
		shipped. The Flash memory SIMM is also referred to as
		nonvolatile random access memory (NVRAM). This
		type of memory retains its contents when system power
		is off.
Flash Memory Card		A Flash memory card inserted in a PCMCIA slot on the
		GRP, and loaded with the default software image, can
		serve as an external storage medium for the default Cisco
		IOS software image shipped with your router.
TFTP Server		You can download and store a valid Cisco IOS software
		image via a Trivial File Transfer Protocol (TFTP) using
		a Telnet connection.

Conditions to Check Before System Startup

Ensure that the following conditions are met before starting up the router:

•All cards are completely inserted into their card cage slots

•All captive screws are tightened

•All interface cable connections are secure

•All the power source cables are secured to the PDU

•All power cables are connected to the appropriate power source

•A terminal device is connected, powered on, and configured to 9600 bps, 8 data bits, no parity, and 2 stop bits (9600,8N2)

•A Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 (zero)

By default, the software configuration register is set to 0x0102, causing the system to boot automatically from the Cisco IOS software image stored on the Flash memory card. New Flash memory cards must be formatted before use. To format a new Flash memory card, refer to the section “Formatting a Flash Memory Card, page 3-67”.
