Console and Auxiliary Port Cable Connections


Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. The DCE-mode console port is for connecting a console terminal and the DTE-mode auxiliary port is for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your router.



Step 1 Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2).

Step 2 Use an auxiliary and console port cable. (An auxiliary port and console port cable and adapter kit is available from Cisco Systems—Product Number ACS-2500ASYN=.) Use the console cable to connect the terminal to the console port. After you establish normal router operation, you can disconnect the terminal.



Note You must supply your own interface cable between the auxiliary port and the equipment you are connecting. For console and auxiliary port pinouts, see the online Cisco 7401ASR Installation and Configuration Guide.


Gigabit Ethernet and Fast Ethernet Port Connections

The Cisco 7401ASR router has two native 10/100/1000-Mbps Ethernet interfaces. Each interface consists of two physical ports, an RJ-45 media port and a GBIC media port. The RJ-45 media ports provides 10/100-Mbps connectivity while the GBIC media ports provides 1000-Mbps connectivity.


Note The RJ-45 media is not capable of 1000 Mbps. This is only available via the Gigabit Ethernet GBIC media.



Note Any two of the four Ethernet ports may be used at the same time.


For more information, see the online Cisco 7401ASR Installation and Configuration Guide.

Intra-Building Lightning Protection

Shielded cables which are grounded at both ends are required to be used on the 10/100 Ethernet port in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requirement for customer premise installations.


Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.


To identify the RJ-45 cable type, hold the two ends of the cable next to each other so you can see the colored wires inside the ends. The straight-through wire type has colored wires in the same sequence at both ends. In the crossover wire type, the first colored wire at the far left is the third colored wire at the other end. The second colored wire at the far left is the sixth colored wire at the other end.

Attach RJ-45 Ethernet cables to the appropriate connector.


Note Both native Fast Ethernet/Ethernet ports and Gigabit Ethernet ports are reported as GE0/0 and GE0/1 in software. You must use the media-type command to select which media type you want to use before you configure these ports. See "Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces" section.


GBIC Cabling and Connection Equipment

The Gigabit Interface Converter (GBIC) port is a 1000-Mbps optical interface in the form of an SC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Interface Converter models WS-G5486 or GBIC-SX=, WS-G5484 or GBIC-LX/LH=, and WS-G5487 or GBIC-ZX-SM= are supported in the Cisco 7401ASR router. For cabling distances, specifications, and other information, see the online Cisco 7401ASR Router Installation and Configuration Guide at http://www.cisco.com/univercd/cc/td/doc/product/core/7401/7401icg/index.htm.


Note All Gigabit Ethernet GBIC ports have SC-type connectors.

Note There is no support for copper-based GBICs (1000BASET) as these do not conform to the GBIC standard and have not been validated by Cisco.



Step 1 Remove the GBIC plug.

Step 2 Attach the appropriate optical fiber cable directly to the SC-type port on the GBIC. You can use either simplex or duplex connectors for most devices.

Two cables are required for simplex connectors, one cable for transmit (TX) and one for receive (RX).

One cable that has both TX and RX connectors is required for duplex connectors.



Caution If you plan to use a GBIC-LX/LH at distances greater than 984.25 feet (300 meters) over 50/125-micron or 62.5/125-micron multimode fiber, to prevent data transmission problems you must use the mode-conditioning
patch cord.

Step 1 Attach the patch cord to the SC-type receptacle on the GBIC (2).

Step 2 Attach the network ends of your patch cord to the appropriate 1000BASEX equipment in your building cable plant (9).



Note Ensure that you connect the TX and RX ports on one end of the patch cord to the RX and TX ports (respectively) on the other end. Connect TX to RX and RX to TX.


A mode-conditioning patch cord can be used with the GBIC-LX/LH to allow reliable laser transmission between the single-mode laser source on the GBIC and a multimode optical fiber cable.

Port Adapter Cable Connections

The instructions for connecting the cables for each port adapter installed in the Cisco 7401ASR router are in the respective online note for each port adapter. The documents are available on the Documentation CD-ROM and on Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/core/7200vx/portadpt/index.htm. Also see the release notes for any information about a specific port adapter. Release notes are found at http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm.

Step 1 Check that the power switch (2) is in the off (O) position.

Step 2 Plug the power cable into the AC connector (1) on the router.

Step 3 Plug the AC power supply cable into the AC power source.


Connect DC-Input Power


Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.



Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.



Step 1 At the rear of the router, check that the power switch is in the off (O) position.

Step 2 Ensure that no current is flowing through the DC power supply leads. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Step 3 Using a wire stripper, strip approximately 0.55 inch (14 mm) from the -V and +V leads.

Step 3 During the boot process, observe the system LEDs. The STATUS LED comes on immediately as amber, then turns to green when the IOS is booted. Port adapter LEDs go on and off irregularly.

Step 4 Observe the initialization process. The LEDs on the port adapter behave differently (most flash on and off). The ENABLED LED on each port adapter goes on when initialization is completed and the console screen displays a script and system banner.


7 Configure the Router

Perform a Basic Configuration Using the Setup Facility

If you do not plan to use AutoInstall, do not connect the router's serial (WAN) cable to the channel service unit/data service unit (CSU/DSU). If the WAN cable is not connected, the router boots from Flash memory and goes automatically into the setup facility.

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

If the serial (WAN) cable is connected to the CSU/DSU and the router does not have a configuration stored in NVRAM, the router attempts to run AutoInstall at startup. The router may take several minutes to determine that AutoInstall is not set up to a remote TCP/IP host. Once the router determines that AutoInstall is not configured, it defaults to the setup facility.

Configure Global Parameters

When you first start the setup program, you must configure the global parameters. These parameters are used for controlling system-wide settings. Complete the following steps to enter the global parameters:


Step 1 Connect a console terminal to the console port, and then boot the router.

The system boots from Flash memory. The following information appears after about 30 seconds. When you see this information, you have successfully booted your router:

Press RETURN to get started!

Note The first two sections of the configuration script (the banner and the installed hardware) appear only at initial system startup. On subsequent uses of the setup command facility, the script begins with a System Configuration Dialog as shown in the following example.


--- System Configuration Dialog ---
 
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.

Step 2 When asked if you want to enter the initial configuration dialog and see the current interface summary, enter yes or press Return:

Would you like to enter the initial configuration dialog? [yes]:

First, would you like to see the current interface summary? [yes]:

In the following example, the summary shows a Cisco 7401ASR router at first-time startup; that is, 
nothing is configured. 
Any interface listed with OK? value "NO" does not have a valid configuration
 
Interface 	        IP-Address	        OK?       	Method            	Status	          Protocol

FastEthernet1/0	  unassigned	         NO	        unset	              down	           down

Step 3 Choose which protocols to support on your interfaces. For Internet Protocol (IP)-only installations, you can accept the default values for most of the questions. A typical configuration using IP, IPX, and AppleTalk follows and continues through Step 5:

Configuring global parameters: 

Enter host name [Router]:

Step 4 Enter enable secret, enable, and virtual terminal passwords:

The enable secret password is a one-way cryptographic secret  
password used instead of the enable password when it exists.

Enter enable secret: barney

The enable password is used when there is no enable secret 
password and when using older software and some boot images.

Enter enable password: betty

Enter virtual terminal password: fred

Step 5 The Simple Network Management Protocol (SNMP) is the most widely supported open standard for network management. It provides a means to access and set configuration and run-time parameters of routers and communication servers. SNMP defines a set of functions that can be used to monitor and control network elements.

Enter yes or press Return to accept SNMP management; enter no to refuse it:

Configure SNMP Network Management? [yes]:

Configure DECnet? [no]:
Configure CLNS? [no]:
Configure bridging? [no]:
Configure XNS? [no]:
Configure Apollo? [no]:

Step 7 For the following queries, enable routing on AppleTalk and IPX:

Configure AppleTalk? [no]: yes
Multizone networks? [no]: yes

Configure IPX? [no]: yes

Step 8 In most cases you use IP routing. If you are using IP routing, you must also select an interior routing protocol. You can specify only one of two interior routing protocols to operate on your system using the setup facility: Interior Gateway Routing Protocol (IGRP) or Routing Information Protocol (RIP). To configure IP routing, enter yes (the default) or press Return, and then select an interior routing protocol:

Configure IP? [yes]:
Configure IGRP routing? [yes]:
Your IGRP autonomous system number [1]: 15

The following sample display includes a continuous listing of all configuration parameters selected in Step 3 through Step 8. Only IP, IPX, and AppleTalk are the selected protocols for this example.

Step 9 Save your settings to NVRAM. See the "Save the Running Configuration to NVRAM" section. If you do not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.


Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces

Changing the Media Type


Note The Cisco 7401ASR router reports both the Fast Ethernet/Ethernet and the Gigabit Ethernet ports as GE 0/0 and GE 0/1. Before configuring either port type, you must first use the media-type interface command to select the media type, either Gigibit Ethernet (gbic) or Fast Ethernet/Ethernet (rj45).



Step 1 To be able to use a particular media port, use Cisco IOS to select the media type. This is done by using the media-type interface command:

media-type { gbic | rj45 }

Example:
interface GigabitEthernet 0/0
media-type rj45
end

Step 2 After changing the media type, configure the speed and duplex to appropriately match the new interface characteristics. Changing the speed and duplex of a Cisco 7401ASR router Gigabit Ethernet interface is done using the speed and duplex interface commands.


Note These commands are only applicable when using the RJ-45 media.


speed { 10 | 100 | 1000 | auto }

duplex { full | half | auto }


The following speed/duplex settings are supported:

Media Type 	       Speed                Duplex 
------------------------------------------------------- 
RJ45		          10, 100, auto	       full, half, auto
GBIC              ignored (1000)       ignored (full)		       (By default on this interface)
-------------------------------------------------------

When using the GBIC media, there is also the additional negotiation auto command that is used to enable the IEEE 801.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

Step 3 To turn the negotiation auto feature off (it is on by default), issue the interface command no negotiation auto. This is useful for connecting to other Gigabit Ethernet equipment that does not support 802.1z autonegotiation.


Note The negotiation auto feature is not supported when using the media type rj-45 and will be ignored if implementation is attempted.


If you change from the GBIC to the rj-45 media type, you must set speed and duplex after you have executed the media-type command to ensure the interface will operate in the correct mode.

The media-type GBIC mode will always default to 1000-Mbps, full-duplex operation as this is the only configuration that is supported in this mode. Any speed or duplex commands are ignored while using this media type, even if present in the config (for example, show running-config).


Debug

Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is either 0 or 1) and show controllers GigabitEthernet 0/X  (where X is either 0 or 1).

The output of the show interface command is useful for determining the current operating mode of the interface (speed/duplex/media-type) and the current interface statistics.

The output of the show controller command displays more information specific to the Cisco 7401ASR router Gigabit Ethernet interface. For example, it shows the detected link status, speed, and duplex, and also determines the current status of autonegotiation and the link partners' abilities (if it is an autonegotiation-capable interface).

The show controller command also displays the current operating state of the driver and the Ethernet controller hardware. The show controller command is a very powerful debugging aid, especially for Cisco engineers should you need help in debugging a problem. If you have any problems with your Gigabit Ethernet interfaces, you will need to provide this information to Cisco for analysis.

Reset the Interface

Should you have a problem with your interface and wish to try and reset it, use the command:
clear interface GigabitEthernet 0/X    (where X is either 0 or 1)

Clear Counters

Interface counters may be cleared (reset) by using the command:

clear counters GigabitEthernet 0/X    (where X is either 0 or 1)

This will not reset the interface.

Configure Port Adapter Interfaces

Following are the steps for configuring interfaces to allow communication over a LAN or WAN. To configure the interface parameters, you need your interface network addresses and subnet mask information. Consult with your network administrator for this information.

Configure ATM Interfaces

In the following example, an ATM interface in slot 1 is configured for an ATM LAN using IP. Follow these steps to configure an ATM interface:


Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Step 4 Save your settings to NVRAM. See the "Save the Running Configuration to NVRAM" section. If you do not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.


Note If additional Ethernet interfaces are available in your system, you are prompted for their configurations as well.



Configure Synchronous Serial Interfaces

Synchronous serial interfaces are configured to allow connection to WANs through a CSU/DSU. In the following example, a synchronous serial interface in slot X is configured for a WAN connection using IP. Follow these steps to configure synchronous serial interfaces:


Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Configuring interface parameters:

Configuring interface serial 1/0:
Is this interface in use? [yes]: 
Configure IP on this interface? [yes]: 
IP address for this interface: 1.1.1.30

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://tools.cisco.com/RPF/register/register.do

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

When you call the center, please have available your service agreement number and your product serial number.
