Powering On the System

When all of the interfaces are connected, perform a visual check of all connections and then check that:

•The ejector levers on each line card are in the locked position.

•All top and bottom line card retaining screws are tight.

•All network interface cables are connected to the line cards.

•The console terminal is turned on.

•A PCMCIA flash memory card installed in the PRE.

You are now ready to power on the system for the first time using the following procedure:

Figure 4-1 Cisco 10008 Router DC PEM Power Switches

Step 1 Remove the tape from the building circuit breaker switches and set the circuit breaker to the On position.

At the front of the chassis, set the circuit breakers on the PEM units to the on ( | ) position (Figure 4-1).

a. The PEM Power LED lights (green), indicating that power is available to the chassis.

If any Fault LEDs (such as Miswire or Single Fan Failure) light (yellow), see the "Troubleshooting Installation Problems" section.

b. The blower module Fan OK LED lights (green), indicating that all fans in the blower are operating properly.

If any Fan Failure LEDs light (yellow), see the "Troubleshooting Installation Problems" section.

c. When the system boot is complete, the PRE begins to initialize the line cards. Go to the "Configuring the Cisco 10008 Router at Startup" section to configure the line cards.

Configuring the Cisco 10008 Router at Startup

This section explains how to create a basic running configuration for your Cisco 10008 router using the Cisco 10008 setup facility or the Cisco IOS command line interface (CLI). For information on modifying the configuration after you create it, see the Cisco IOS configuration and command reference guides.

To configure a Cisco 10008 router from the console, you must connect a terminal or terminal server to the router's console port. To configure the Cisco 10008 router over your management Ethernet, you must have the router's IP address available.

Startup Display

When you power on your Cisco 10008 router or execute the reload command, the console screen displays a message similar to the following:

Basic Configuration Using the Setup Facility

The first time you power on a Cisco 10008 router, the setup facility starts. You can also initiate the facility by running the setup command in privileged EXEC mode. This facility helps you enhance a default configuration that already exists on the Cisco 10008 router. The setup facility uses a question and answer sequence called the System Configuration Dialog to walk you through configuring the router.

You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.

Tip Basic configuration setup is often used as a quick way to achieve network connectivity, allowing you to retrieve a configuration file from a TFTP server.

Using the System Configuration Dialog

Use the System Configuration Dialog to help you perform a basic configuration. Proceed through the dialog by answering questions and then pressing the Enter key. In most cases, you can get additional information by entering a question mark (?). Throughout the dialog, default values are shown in square brackets [ ].

Tip If you have experience using Cisco routers, consider configuring the router by using the procedure described in the "Basic Configuration in Global Configuration Mode" section.

To cancel the configuration dialog, press Ctrl-C, or you can let the dialog help you perform one of two configuration types:

•Basic configuration setup configures only enough connectivity for management of the system.

•Extended setup asks you to configure each interface and is not appropriate for configuring the Cisco 10008 router. For more information, see the Cisco IOS Configuration Fundamentals Configuration Guide.

You can run the setup facility any time you are at the enable prompt (#) by entering the command setup.

Basic System Configuration Procedure

Use the following procedure to perform a basic configuration using the System Configuration Dialog:

Step 1 The dialog starts by asking if you want to continue with the configuration dialog. Enter Yes. To return to the enable prompt, enter No.
--- System Configuration Dialog ---
Continue with configuration dialog? [yes/no]: yes
Step 2 Enter Yes to perform a basic management setup. Enter No to perform an extended configuration setup.
Would you like to enter basic management setup? [yes/no]: yes
Step 3 Specify a hostname. The hostname becomes part of the Cisco IOS prompt.
Enter host name [Router]: my-router
Step 4 Specify a secret password. It appears in encrypted form in the configuration file.
Enter enable secret: my_secret
Step 5 Specify the enable password. It is used if you did not assign a secret one.
Enter enable password: my_password
Step 6 Specify the password to use for telnet sessions.
Enter virtual terminal password: my_vt
Step 7 At the configure system management prompt, enter No.
Configure System Management? [yes/no]: no
Step 8 If you want to access the router using SNMP, enter Yes at the prompt:
Configure SNMP Network Management? [yes]: yes
Step 9 Specify an SNMP community string.
Community string [public]: public
After you respond to the SNMP questions, the setup script lists the interfaces. For example:

Interface

IP-Address

OK?

Method

Status

Protocol

Ethernet0/0/0

unassigned

YES

unset

up

up

FastEthernet0/0/0

unassigned

NO

unset

up

up

Interfaces that are not okay (OK? = NO) do not have a valid configuration.

Step 10 To achieve network connectivity, enter the interface for the FastEthernet interface.
Enter interface name used to connect to the management network from the above interface 
summary: FastEthernet0/0/0
Step 11 Accept the default value for the type of connector. RJ-45 is the only connector that can be used on the Cisco 10008 router Ethernet port.
Configuring interface FastEthernet0/0/0:
Use the 100 Base-TX (RJ-45) connector? [yes]: yes
Step 12 Configure both the Cisco 10008 router and the remote device to use the same mode.
Operate in full-duplex mode? [no]: no
Step 13 You must enter the IP address to achieve network connectivity.
Configure IP on this interface? [yes]: yes
Step 14 Specify the IP address.
IP address for this interface: 172.27.48.209
Step 15 Enter the subnet mask for the IP address.
Subnet mask for this interface [255.255.0.0] : 255.255.0.0
The system displays the information you entered as well as several default commands, such as the no shutdown command. For example:
The following configuration command script was created:
hostname c10008
enable secret 5 $1$uror$EFU0hKOBQXhk975qKFZlL0
enable password lab
line vty 0 4
password lab
no snmp-server
!
no ip routing
!
interface FastEthernet0/0/0
no shutdown
media-type 100BaseX
half-duplex
ip address 172.27.48.209 255.255.0.0
!
end
Step 16 The setup script concludes by giving you the choice to exit without saving, start the setup script, or save the configuration file:
[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
Enter your selection [2]:
Step 17 After you complete the configuration dialog, enter global configuration mode and enable ip routing by entering the ip routing command:
router(config)#ip routing
Basic Configuration in Global Configuration Mode

The following command sequence allows you to perform a configuration similar to that generated by the setup command.
Router>configure terminal
Router(config)#hostname c10008
Router(config)#enable secret my_router
Router(config)#enable password my_rtr
Router(config)#snmp-server community public
Router(config)#ip routing
Router(config)#interface FastEthernet0/0/0
Router(config-if)#no shutdown
Router(config-if)#media-type 100BaseX
Router(config-if)#half-duplex
Router(config-if)#ip address 3.5.3.45 255.255.0.0
Router#copy running-config startup-config
You can now configure the line cards. For specific information on system and interface configuration, see the Cisco 10000 Series Router Line Card Configuration Guide.

Formatting Flash Memory Cards and Disks

The Flash memory disk card that shipped with your router contains the default Cisco IOS image for booting your router. This section explains how to format an ATA flash disk, modify its contents, or resolve a problem with the card.

Caution The formatting procedure erases all information on a Flash memory disks or cards.

Flash memory ATA disks and Flash memory cards use similar commands. The primary syntax change is that disk0: or disk1: refers to Flash memory ATA disks while slot0: or slot1: refers to Flash memory cards.

Use the following procedure to format a Flash memory disk:

Step 1 To format a Flash memory disk, you should be in privileged EXEC mode.

Step 2 Ensure there is a Flash memory disk in PCMCIA slot 0 or slot 1 of the PRE.

Step 3 Enter the format diskn: command at the privileged EXEC mode prompt to format the disk.

The following example shows the display after you enter the format disk0: command:
Router# format disk0: 
All sectors will be erased, proceed? [confirm] 
Enter volume id (up to 30 characters): MyNewdisk 
Formatting sector 1 
Format device slot0 completed 
Router#
The Flash memory disk is now ready for use.

Managing the File Systems

This section describes the file systems used on the Cisco 10008 series router and provides procedures for performing the following basic file system tasks:

•File Systems

•Copying the Startup Configuration to the Running Configuration

•Managing Configuration Files Larger than NVRAM

File Systems

The Cisco 10008 series router includes the file systems described in Table 4-1.

Table 4-1 Cisco 10008 Series Router Principal File Systems

Disk refers to an ATA Flash disk (48 or 128 MB).

Slot refers to a Flash memory card (8, 16, or 20 MB).

0 refers to the left slot on the PRE.

1 refers to the right slot on the PRE.

Secondary refers to the secondary PRE in a redundant system.

FTP
TFTP
RCP

ftp:
tftp:
rcp:

Protocols used for accessing files that are stored remotely.

Flash memory disks and the smaller Flash memory cards use similar commands. The primary syntax change is that disk0: or disk1: refers to Flash memory disks, and slot0: or slot1: refers to Flash memory cards.

You can use the privileged EXEC commands dir, del, and copy to manage the contents of the file systems. You can also use the commands mkdir and rmdir to create and remove directories on Flash disks. You cannot use the commands squeeze and undelete on Flash disks. For more information, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.

Copying the Startup Configuration to the Running Configuration

Use the copy startup-config running-config command to copy the startup configuration file on NVRAM to the running configuration. If your startup configuration file is approaching the NVRAM limit of 512 KB, you must either compress it or relocate it as described in the following sections.

Tip If your configuration file is large, run the copy startup-config running-config command during off-peak hours. This command might slow down traffic for several minutes while the system is merging the starting and the running configurations.

Managing Configuration Files Larger than NVRAM

To maintain a configuration file that exceeds the size of NVRAM (512 KB), you must compress or relocate the configuration file. This section provides an example of each approach. For more information, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.

Compressing the Configuration File

Use the service compress-config global configuration command to compress the configuration file for storage in NVRAM. A compressed file can take several minutes longer to load than an uncompressed file.

To compress configuration files, use the following commands, beginning in global configuration mode:

Step 1 Specify that the configuration file is to be compressed.
Router(config)# service compress-config
Step 2 Exit global configuration mode.
Router(config)# end
Step 3 Use one of the copy commands to copy the new configuration. For example:
Router# copy running-config startup-config
Building configuration...
Compressing configuration from 129648 bytes to 11077 bytes
[OK]
To cancel the compression feature, use the no service compress-config command.

Note If you try to load a configuration that is more than three times larger than the NVRAM size, the following error message appears: [buffer overflow—file-size/buffer-size bytes].

Relocating the Configuration to a Flash Disk

To run the startup configuration off a Flash disk, use the following commands beginning in privileged EXEC mode:

Step 1 Copy the current startup configuration to a new location. In the following example, the configuration file is copied from a TFTP server to a Flash disk in slot 0:
Router# copy tftp://172.16.2.15/example-config disk0:router-config
Step 2 Enter global configuration mode.
Router# configure terminal
Router(config)#
Step 3 The buffer that holds the configuration file is usually the size of NVRAM (512 KB). Larger configurations need larger buffers. Change the size of the buffer that holds the configuration commands.
Router(config)# boot buffersize 1024000
Step 4 Specify that the startup configuration file is located in Flash memory by setting the CONFIG_FILE variable. In the following example, the system is told that the boot configuration file is in slot 0 and the filename is router-config:
Router(config)# boot config disk0:router-config
Step 5 Exit global configuration mode.
end
Step 6 When you finish changing the running-configuration, save the new configuration.
Router# copy running-config startup-config
As a result of this procedure, when you reboot the Cisco 10000 series router, it loads the configuration file that resides on Flash disk 0.

Managing System Boot Parameters

This section tells you how to use Cisco IOS to modify PRE boot parameters by changing the configuration register settings.

During the boot process, the system reads a configuration register that defines certain system parameters. The software configuration register is a 16-bit register in NVRAM used to define such characteristics as

•The source of the Cisco IOS software image required to run the router

•Whether the system software should ignore the contents of NVRAM

•The behavior of the Break function

By modifying the boot parameters, you can customize your Cisco 10000 series router. For example, a common configuration register setting in some lab environments is 0x2100. Using this setting, the system boots to the ROM monitor prompt, where a technician can load a specific image by entering the boot command at the rommon prompt. (For more information, see the Cisco IOS Configuration Fundamentals Configuration Guide.)

Changing the Configuration Register Settings

To change the configuration register settings while you are running system software, perform the following steps:

Step 1 From global configuration mode, enter the config-register value command to set the contents of the software configuration register; value is a hexadecimal number preceded by 0x. For example:
Router(config)# config-register 0x2100
Consult the hexadecimal column in Table 4-2 for the possible settings to enter as the 4-bit value parameter.

Step 2 Exit global configuration mode by pressing Ctrl-Z.
Router(config)# Ctrl-Z 
Router#  
The new contents of the software configuration register are saved to NVRAM. These new settings do not take effect until you reload the system or reboot the router.

Step 3 To display the new software configuration register setting, issue the show version command.
Router# show version 
.
.
. 
#Configuration register is 0x141 (will be 0x2100 at next reload)
Step 4 Save the configuration file to preserve the new software configuration register settings.
Router# copy running-config startup-config
Step 5 Reboot the router.

The software configuration register setting takes affect only after you reload the system. This happens when you issue the reload command from the console or reboot the router.

Configuration Register Settings

Table 4-2 summarizes the modifications that you can make to the software configuration register. For detailed information, refer to the Cisco IOS Configuration Fundamentals Command Reference.

Note The factory default value for the software configuration register is 0x2102. This value is a combination of the following: binary bit 8 = 0x0100, bits 00 through 03 = 0x0002, and bit 13 = 2000.

Table 4-2 Definition of Bits in the Software Configuration Register

Predeployment Testing

Laboratory testing is a prerequisite for new equipment deployment. The aim of the testing is to certify the product for use in the network.

In the lab, the product is typically evaluated to

•Verify its interoperability with other network connected equipment

•Verify the performance and stability of a platform

•Test software services and features during simulated operation

•Verify that the product is NEBS compliant

Labs have a certification plan for measuring product stability and interoperability. After the platform demonstrates that it can pass the certification plan, it is deployed.

During performance testing, lab personnel:

•Refer to vendor documentation to make sure that the product meets vendor benchmarks.

•Often have specialized tools for testing, and might test the functionality in cooperation with customers who are interested in using the product.

Troubleshooting Installation Problems

This section contains general troubleshooting information to help you solve any problems you might encounter during the installation of the system. For any problems not covered in this section and for more detailed troubleshooting information, see the Cisco 10000 Series Router Troubleshooting Guide.

Table 4-3 General Troubleshooting Tips

Symptom

Steps to Take

System fails to power on

Check that:

•All power cords are properly connected to the Cisco 10008 router and at the power connection end.

•The PEM power switches are in the On position.

–For DC PEMs, the POWER LED should be on (green).

•The blower module is fully inserted (FANS OK LED is on (green).

System fails to boot up properly

If the system has power, check the FAIL LED on the PRE and any information on the alphanumeric display. If the FAIL LED is on, see the Cisco 10000 Series Router Troubleshooting Guide.

DC PEM problem

•If the FAULT LED is on, see the Cisco 10000 Series Router Troubleshooting Guide.

•If the MISWIRE LED is on, the -48V and return (RTN) wires are reversed. Power off the PEM and reconnect the wires correctly (see the "Connecting DC Power to the Cisco 10008 Router" section).

System experiences a critical alarm (Critical LED on the PRE is on)

Enter the show facility-alarm status command at the console.

System experiences a major alarm (Major LED on the PRE is on)

Enter the show facility-alarm status command at the console.

System experiences a minor alarm (Minor LED on the PRE is on)

Enter the show facility-alarm status command at the console.

You cannot establish a console or Telnet connection to the system.

For information about troubleshooting Ethernet connections, see the "Troubleshooting Ethernet Connections" section.

For information about troubleshooting the console port serial connections, see the "Troubleshooting the Console Port Serial Connection" section.

Fan Failure

Perform the following if a FAN FAILURE LED lights:

•Reseat the blower module (see the "Replacing the Blower Module" section).

•Remove the rear safety cover and be sure that the blower module cable is connected securely (see the "Replacing the Blower Module" section).

System overheats

This may be due to a failure in the blower module (see Fan Failure above), insufficient ventilation, or high ambient temperature. See the Cisco 10000 Series Router Troubleshooting Guide for additional information.

Troubleshooting Ethernet Connections

If an Ethernet connection to your Cisco 10008 router fails to work properly, and the corresponding LNK (Link) LED is not on, check for the following problems:

•Visually check that an Ethernet cable is connected to the correct Ethernet port on the PRE, and that the other end of the cable is connected to an Ethernet hub that is powered on and functioning properly.

•Check to see if you are using the correct type of cable. The cable must meet the specifications given in the "Connecting to a 10BASE-T Ethernet Network" section.

•The cable might be bad or broken. Replace the cable with a known, reliable straight-through Ethernet cable, checking to be sure the LNK LED comes on (green).

–If the LNK LED is still off, it is possible that the Ethernet port might be functioning properly, but the LED is not working. Check the Ethernet port (by trying to ping over it, for example) to determine if the problem is due to a bad LED or if the Ethernet link is bad.

•Make sure the PRE has booted up properly as follows:

–The Status LED should be on (green).

–If the Fail LED is on (yellow), see the Cisco 10000 Series Router Troubleshooting Guide for troubleshooting information.

•Check the hub:

–Is the cable connected into the correct hub port (for example, the hub LED is on, but the LNK LED on the PRE is not on).

–Be sure that the cable is not connected to an uplink port.

•If the LNK LED is on (green), but the Ethernet port does not seem to be working properly, make sure that the port in question is configured properly and is not administratively shut down. If you have a working console connection, perform the following steps:

–At the router prompt, enter show int fast0/0/0. If the port is administratively down, enter these commands to enable it:
switch> configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
router(config-if)# int fast0/0/0
router(config-if)# no shut
router(config-if)# exit
router(config)# exit
router#
–Check that the Ethernet port in question has a valid IP address assigned to it.

For more information about configuring Ethernet ports, see the Cisco 10000 Series Router Line Card Configuration Guide.

If the cable, connections, power, and configuration all check out, and you still cannot connect to the Ethernet port on the module, you probably need to replace the PRE. Contact the Cisco TAC for further assistance.

Troubleshooting the Console Port Serial Connection

If the terminal connected to the Cisco 10008 console port appears frozen or fails to work properly, check for the following problems:

•Check the console cable and make sure it is properly connected to the correct console port on the PRE, and to your equipment at the other end.

•Verify that you are using the proper type of cable and adapter. For additional information about cable pinouts, see the "Connecting a Video Terminal to the PRE Console Port" section.

•To be sure the cable is not defective or broken, replace the cable with another high quality cable if possible.

•Check that your terminal equipment is working properly and configured with the correct settings for the console port. The default console port settings are:

–9600 baud

–8 data bits

–1 stop bit

–No parity

–No flow control

•Check the LEDs on the PRE to make sure that it is powered on properly.

•If the cable, connections, power, and terminal settings are all acceptable and you still cannot connect to the console port on the module, you probably need to replace the PRE. Contact the Cisco TAC for further assistance.
