19 For more information, see the online Cisco 7401ASR Installation and Configuration Guide. Figure 14 Gigabit Ether net and Fast Ether ne t/Ether net Por t Identification Fast Ethernet RJ-45 Connectio.
20 Note Both native Fast Ethernet/Ethernet ports and Gigabit Ethern et ports are reported as GE0/0 and GE0/1 in software. Y ou must use the media-type command to select which media type you want to use before you conf igure th ese ports. See “Configure the Native Giga bit Ethernet and Fast Ethernet/Ethernet Interfaces” section on page 28.
21 Step 2 Attach the appropriate optical fiber cable directly to the SC -type port on the GBIC. Y ou can use either simplex or duplex connectors for most devices. T wo cables are required for simplex connectors, on e cable for transmit (TX) and one for rece ive (RX).
22 Port Adapter Cable Connections The instructions for connecting the c ables fo r each port adapte r insta lled in the Cisco 7401ASR ro uter are in the respec tive online note for each port adapter . Th e documents are available on the Documenta tion CD-ROM and on C isco.
23 6 Connect Power to the Router This section provides instructions for attaching the pow er cables to the router and powering on the router . War n in g This unit might have more than one power cord. T o reduce the risk of electric shock, disconnect the two power supply cords before servicing t he unit.
24 Step 2 Ensure that no current is flowing through the DC power supply leads. T o ensure that all power is OFF , locate the circuit breaker on the panel board that services the DC circuit, sw itch the circuit breaker to th e OFF position, and tape the switch handle of the circuit breaker in the OFF posi tion.
25 Start the Router Step 1 Place the power switch in the on (|) position. Step 2 Listen for the fans; they should be operating as soon as power is tu rned on. Note After powering off the router , wait at least 30 seconds before p owering it on again. The following table provides information about the LEDs as the system starts.
26 7 Configure the Router Perform a Basic Configuratio n Using the Setup Facility If you do not plan to use Auto Install, do not connect the router ’ s serial (W AN) cable to the channel service unit/data service unit (CSU/DSU).
27 Note The first two sections of the configuration script (the ba nner and the installed hardware) appear only a t initial system startup. On subsequen t uses of the setup command facility , the script begins with a System Configuration Dialog as show n in the following example.
28 Step 7 For the following queries, enab le routing on AppleT alk 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.
29 Step 1 T o 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 Giga.
30 Reset the Interface Should you have a problem with your in terface and wi sh to try and reset it, use the command: clear interface GigabitEthernet 0/X (where X is either 0 or 1) Clear Counters Inte.
31 Configure Fast Et hernet Interfaces In the following example, a Fast Ethernet interface in slot X is configured for a Fast Ethernet LAN using IP . Follow thes e steps to configure Fast Ethernet int.
32 Step 3 If you are using App leT alk on the interface, enter yes . Enter yes to configure for extended AppleT alk networks, and then enter the cable range number .
33 The following configuration command script was created: hostname Router enable secret 5 $1$u8z3$PMYY8em./8sszhzk78p/Y0 enable password betty line vty 0 4 password fred snmp-server community public .
34 Check the Running Configuration Settings T o check the value o f the settings yo u have ente red, enter the show running-config command at the Router# prompt: Router# show running-config T o review change s you make to the configuration, use the EXEC mode show startup-config command to display the information stored in NVRAM.
