Step 1 Connect any LAN cables to the LAN ports.
Step 2 If using an external CSU/DSU, connect the router’s serial interface to the CSU/DSU, and the CSU/DSU to the line from the telco.
Step 3 If using an internal CSU/DSU, connect the router’s serial interface to the line from the telco.
Step 4 Connect the router’s console port to a PC (using a rollover cable), as needed, to configure the router.
Step 5 Connect a power cable from a power outlet to the power port on the router.
Step 6 Turn on the router.
■ User and Enable (privileged) mode
■ Entering and exiting configuration mode, using the configure terminal, end, and exit commands, and the Ctrl-Z key sequence
■ Configuration of console, Telnet, and enable secret passwords
■ Configuration of SSH encryption keys and username/password login credentials
■ Configuration of the host name and interface description
■ Configuration of Ethernet interfaces that can negotiate speed, using the speed and duplex commands
■ Configuring an interface to be administratively disabled (shutdown) and administratively enabled (no shutdown)
■ Navigation through different configuration mode contexts using commands like line console 0 and interface
■ CLI help, command editing, and command recall features
■ The meaning and use of the startup-config (in NVRAM), running-config (in RAM), and external servers (like TFTP), along with how to use the copy command to copy the configuration files and IOS images
■ The process of reaching setup mode either by reloading the router with an empty startup-config or by using the setup command
■ The questions asked in setup mode differ.
■ Routers have an auxiliary (Aux) port, intended to be connected to an external modem and phone line, to allow remote users to dial into the router, and access the CLI, by making a phone call.

1. What is the IP address or host name of the TFTP server?
2. What is the name of the file?
3. Is space available for this file in Flash memory?
4. Does the server actually have a file by that name?
5. Do you want the router to erase the old files?
1. The router performs a power-on self-test (POST) to discover the hardware components and verify that all components work properly.
2. The router copies a bootstrap program from ROM into RAM, and runs the bootstrap program.
3. The bootstrap program decides which IOS image (or other OS) to load into RAM, and loads that OS. After loading the IOS image, the bootstrap program hands over control of the router hardware to the newly loaded OS.
4. If the bootstrap program loaded IOS, IOS finds the configuration file (typically the startup-config file in NVRAM) and loads it into RAM as the running-config.
