a. Referring to the topology diagram, connect the console (or rollover) cable to the console port on the

router and the other cable end to the host computer with a DB-9 or DB-25 adapter to the COM 1 port.

Ensure that power has been applied to both the host computer and router.

b. Establish a HyperTerminal or other terminal emulation program connection to the router.

a. From the privileged EXEC prompt, issue the reload command. Confirm the reload when prompted.

b. Observe the output as the router restarts.

Output similar to this will be displayed.

The startup process has three stages:

Examine the output displayed. Look at the highlighted section in the sample output in this lab that

relates to the POST. Mark any differences between your observed output and this sample.

What are possible reasons for these differences?

What does the POST test in the router?

If the POST is successful, what is loaded into RAM?

What is the purpose of what is loaded into RAM?

What would happen if the POST is unsuccessful, and what could this mean?

Examine the displayed output. Look at the sample output in this lab that relates to the IOS loading.

Mark any differences between your observed output and this sample.

What are possible reasons for these differences?

What are the three possible locations of the IOS?

How is the IOS location to be used specified?

Konfigurasi nilai register

The confreg program is available to decode configuration register values. It can be downloaded from

Academy Connection Tools. From Tools, select the CCNA Curriculum (not CCNA Discovery or CCNA

Exploration), and then select any v3.1 course. Click Cisco Configuration Register Decoder to

download the program.

After it is installed and executed, the program displays the binary and hexadecimal values of the

register that set the different router startup sequences and console communications.

What will be the result if an IOS image cannot be located and loaded?

Examine the displayed output. Look at the sample output in this lab that relates to the startup

configuration loading. Mark any differences between your observed output and this sample.

What are possible reasons for these differences?

What is the output if the router does not have a configuration to load?

What is displayed if a startup configuration is loaded?

Erase the configurations and reload the router. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), delete the IOS image file from the TFTP directory, reconnect the appropriate cabling, and restore the TCP/IP settings.

Prepare a troubleshooting checklist based on the router startup stages and the hardware and software

features associated with each stage. Format the checklist so that if it is noted that a stage was unsuccessful, the possible problems can be readily identified. For example, for “IOS not loaded” enter “ROMON prompt displayed.” Prepare a second checklist listing possible router faults or problems. For example, “no cooling fan sound,” “LEDs not illuminated or showing unusual behavior,” or “unexpected ROMON prompt displayed.” For each problem listed, enter the stage of the router startup process that failed.

Examine the router. In the table below, identify and match each item number in the figure with the description. In addition, record the number of each interface and port on the router with the description.

Is a module installed in Slot 0? No

How many Fast Ethernet interfaces does the router have?

WIC-2T two serial interfaces

Is a module installed in Slot 1?

Which of the modules and ports have the potential to be upgraded to improve the router’s

capabilities?

a. Referring to the topology diagram, connect the console (or rollover) cable to the console port on the

router and the other cable end to the host computer with a DB-9 or DB-25 adapter to the COM 1 port.

Ensure that power has been applied to both the host computer and router.

b. Establish a HyperTerminal or other terminal emulation program connection to the router.

c. From the privileged EXEC mode prompt of the terminal, issue show run and show flash:

commands.

Record the number and type of interfaces. Typical results are shown.

Record the details of the memory (DRAM, flash) modules.

Are there any differences between the physical and IOS inspections?

Observed differences could be due to the IOS having features implemented in the software that do not have the hardware module installed, or loopback interfaces may be configured.

If an installed hardware interface does not appear in the configuration, it may be faulty or may not be correctly installed. In some cases, slots must be filled consecutively; in other cases, certain module types can only be installed into specified slots.

After establishing the current hardware status of the router, examine the technical documentation to

determine the potential for upgrading and growth.

a. Go to the website http://www.cisco.com.

b. In the Quick Links pane on the right, select Documentation.

c. Under Select a category, click Routers. Under Select a product, click the Cisco 1800 Series

Integrated Services Routers link.

d. Review the documentation links displayed.

e. Under Product Literature, click the Data Sheets link. Note the range of data sheet documentation

available.

f. Click Cisco 1800 Series Integrated Services Routers: Cisco 1841 Router (Modular).

a. Read through the Cisco 1800 Series Integrated Services Routers: Cisco 1841 Router (Modular)

document, noting the structure and format of the information.

b. From Table 1, Architecture Features and Benefits of Cisco 1841 Router, record the following

information:

The number of different modules and interface cards that are supported: >30

Default memory capacity:

Cisco IOS versions supported:

c. From Table 5, Product Specifications of Cisco 1841 Router, locate and record the following

specifications from the Architecture section.

d. From the Table 6, Modules and Interface Cards the Cisco 1841 Router Supports, list the 10

different categories of interface card (WIC) supported by the 1841 platform.

e. From Table 6, what feature does the Advanced Integration Module (AIM) enable to be installed in an

1841 router?

The 1841 ISR has removable and interchangeable modules. Various optional modules can be installed in the router to provide specific capabilities. These modules are installed either by inserting them into slots on the chassis, or by opening the chassis and plugging them into connectors inside.Flash memory and interface cards fit into slots on the chassis and are installed and removed without opening the chassis.

There are three types of interface cards for the 1800 series modular routers:

The following components plug into connectors inside the chassis and are installed and removed only by

opening the chassis:

Summarize the changes that are possible for this router. This information is important to have and consider when planning and designing the network upgrade.

If the router is not at its limit of these features, candidates for upgrading could include:

Flash memory (if larger IOS required)

Erase any configurations and reload the router. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Network device capabilities are continuously developing. Consider the advantages of a modular platform over that of a device with a fixed hardware platform.
