5 Connect the Router to the Network This section provides information about cables and ports and attaching the router to the network.
For more information, see the online Cisco 7401ASR Installation and Configuration Guide.
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 on page 28. Note 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.
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. Step 2 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. If you plan to use a GBIC-LX/LH at distances greater than 984.25 feet (300 meters) over 50/125-micron or 62.
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.
6 Connect Power to the Router This section provides instructions for attaching the power cables to the router and powering on the router. Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. Warning The AC power supply has double pole/neutral fusing. The Cisco 7401ASR router comes with either an AC or DC power supply. A dual DC power supply option is available.
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.
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 turned on. Note After powering off the router, wait at least 30 seconds before powering it on again. The following table provides information about the LEDs as the system starts. Figure 22 Identifying LEDs and LED Status 2 5 3 6 4 7 57605 1 9 10 8 No.
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.
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 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).
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.
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.
Configure Fast Ethernet Interfaces In the following example, a Fast Ethernet interface in slot X is configured for a Fast Ethernet LAN using IP.
Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and then enter the cable range number. Enter the zone name and any other additional zones that are associated with your local zone: Configure AppleTalk on this interface? [no]: yes Extended AppleTalk network? [no]: yes AppleTalk starting cable range [0]: Step 4 Save your settings to NVRAM. See the “Save the Running Configuration to NVRAM” section on page 33.
