Refer to Table 1 for a list of the pins used on the RJ-45-to-DB-25 adapters, used with an RJ-45 cable, to connect terminals and modems to the Cisco 7201 router. The cable you use may be a roll-over cable or a straight-through cable.

A roll-over cable can be detected by comparing the two modular ends of the cable. Holding the cables in your hand, side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the pin on the outside of the right plug. If your cable was purchased from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a roll-over cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5). (See Figure 10.)

RJ-45 Fast Ethernet cable

When using the Fast Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to it.

However, when the Fast Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface (CLI) commands, the port is forced to MDI mode.

When in a fixed-speed configuration and MDI mode:

•Use a crossover cable to connect to an MDI port

•Use a straight-through cable to connect to an MDI-X port

Connect Native Gigabit Ethernet Cables

The Cisco 7201 router native Gigabit Ethernet ports use either optical fiber or RJ-45 Ethernet cables. For installation information see:

•Install the SFP Module Optical Fiber Cables

•Install the Native Gigabit RJ-45 Ethernet Cables

The SFP port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. (See Figure 13.)

Appendix A, "Specifications" of the online Cisco 7201 Installation and Configuration Guide, provides cabling specifications and configuration information for the SFP modules that you install in the Gigabit Ethernet SFP ports.

Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70

Figure 13 shows the duplex LC-type connectors on your multimode or single-mode optical fiber cables. For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX). For duplex connectors, only one cable that has both TX and RX connectors is required. You can use either simplex or duplex connectors to the SFP ports on the
Cisco 7201 router.

Install the SFP Module Optical Fiber Cables

The SFP module ports support IEEE 802.3z (optical Gigabit Ethernet) interfaces compliant with 1000BASESX and 1000BASELX specifications.

SFP modules ordered with the Cisco 7201 router come installed in the system. Optical fiber cables are commercially available; they are not available from Cisco.

Warning Class 1 laser product. Statement 1008

Warning Class 1 LED product. Statement 1027

Step 1 Remove the plug from the SFP module so that you can insert the optical fiber cables. Keep the plug for use should you ever disconnect the optical fiber cables.

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Step 2 Attach the appropriate optical fiber cable directly to the SFP module. You can use either simplex or duplex connectors for most devices. (Figure 13 shows an SFP module with a duplex connector being installed in SFP port 0/1.)

•For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX).

•For duplex connectors, only one cable that has both TX and RX connectors is required.

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

Mode-Conditioning Patch Cord Description

A mode-conditioning patch cord can be used with the SFP-GE-L= (SFP module) to allow reliable laser transmission between the single-mode laser source on the SFP module and a multimode optical fiber cable.

When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.

A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in Figure 14) to a graded-index multimode optical fiber. Figure 14 shows a diagram of the mode-conditioning patch cord assembly.

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASE-LX and 1000BASE-LH links.

The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord. At the output of the patch cord, the SFP-GE-L= is compliant with the IEEE 802.3z standard for 1000BASE-LX.

Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the
Inspection and Cleaning Procedures for Fiber-Optic Connections document at http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml and the
Compressed Air Cleaning Issues for Fiber-Optic Connections document at http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml. Figure 14 shows one type of mode-conditioning patch cord.

Attach the Mode-Conditioning Patch Cord

To use a mode-conditioning patch cord, follow these steps:

Step 1 If you have not already done so, and the mode-conditioning patch cord has been in use, we strongly recommend cleaning optical fiber connections before attaching cables to equipment.
For information about cleaning fiber-optic cable connectors and receptacles, see the
Inspection and Cleaning Procedures for Fiber-Optic Connections document at http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml and the
Compressed Air Cleaning Issues for Fiber-Optic Connections document at http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml.

Step 2 Attach a mode-conditioning patch cord to the SFP module. (See Figure 14.)

Step 3 Attach the network ends of your mode-conditioning patch cord to the appropriate 1000BASEX equipment in your building cable plant.

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.

Install the Native Gigabit RJ-45 Ethernet Cables

This section provides information about installing the native Gigabit Ethernet RJ-45 cables.

Intra-Building Lightning Protection

Shielded cables, which are grounded at both ends, are required to be used on the 10/100/1000 Gigabit Ethernet RJ-45 ports 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 premises 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. Statement 1021

Proceed to the "Configure the Router" section to configure the router.

6 Configure the Router

Use this section for information on configuring the Cisco 7201 router.

Perform a Basic Configuration Using AutoInstall

The AutoInstall process is designed to configure the Cisco 7201 router automatically after connection to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be preconfigured to provide the required configuration files. The TCP/IP host may exist anywhere on the network as long as the following two conditions are maintained:

1. The host must be on the remote side of the router synchronous serial connection to the WAN.

2. User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host are enabled.

This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not use AutoInstall unless the required files are available on the TCP/IP host. Refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications for information about how AutoInstall works.

Complete the following steps to prepare your Cisco 7201 router for the AutoInstall process:

Step 1 Attach the appropriate synchronous serial cable to synchronous serial interface 0 on the router.

Step 2 Turn the power switch on the power supply to the on (O) position. (This action turns on AC power to the router.) The router loads the operating system image from flash memory. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process begins.

Step 3 Once the AutoInstall process is completed, use the copy running-config startup-config command to write the configuration data to the router's nonvolatile random-access memory (NVRAM). Perform the following step to complete this task.

Step 4 At the # prompt, enter the following command:
Hostname# copy running-config startup-config
Note Completing Step 3 saves the configuration settings that the AutoInstall process created to NVRAM. If you fail to do this, your configuration will be lost the next time you reload 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.

Note 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:

Configure the Native Gigabit Ethernet Interfaces

The Cisco 7201 router reports the Gigabit Ethernet SFP ports as GigabitEthernet 0/0, GigabitEthernet 0/1, GigabitEthernet 0/2, and GigabitEthernet 0/3. The Cisco 7201 router reports the RJ-45 ports as GigabitEthernet 0/0 and Gigabit Ethernet 0/1. Before configuring either the GigabitEthernet 0/0 or Gigabit Ethernet 0/1 interfaces, you must first use the media-type interface command to select the media type, sfp or rj45.

Changing the Media Type

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

media-type { sfp | rj45 }

Example:
interface GigabitEthernet 0/0
media-type rj45
end
Configuring the Interface Transmission and Speed Modes

After changing the media type, configure the speed and duplex transmission modes to appropriately match the new interface characteristics. Changing the speed and duplex of a Cisco 7201 router Gigabit Ethernet interface is done using the speed and duplex interface commands.

Table 3 Supported Speed and Duplex Settings

Media Type

SFP

1000, auto

full, half, auto¹

RJ-45

10, 100, 1000, auto

full, half, auto

¹GE 0/3 only supports full duplex mode.

When using the sfp media type, there is also the additional negotiation auto command that is used to enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

To turn this 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 IEEE 802.1z autonegotiation. We recommended that a fixed speed and duplex setting should be used.

When the interface is configured for negotiation auto, the interface advertises all modes of which it is capable. The link only comes up if the negotiation process succeeds in finding a common mode between the Cisco 7201 SFP media type and its link partner.

The sfp media type always defaults to 1000-Mbps, full-duplex operation. The only available speed in this mode is 1000 Mbps; there is no difference whether 1000 or auto is selected. GE 0/0, GE 0/1 and GE 0/2 support half and full duplex mode; GE 0/3 only supports full duplex mode.

Note Copper SFP modules are considered to be SFP media types, not RJ-45 media types. GE 0/2 and GE 0/3 are optical ports, whether or not a copper SFP module with an RJ-45 connector, or a standard SFP module is installed.

Note The negotiation auto feature is not supported when using the rj-45 media type and will be ignored if implementation is attempted. (Auto negotiation is always on in RJ-45 mode.)

When an RJ-45 interface is enabled, it advertises all modes of which it is capable. The link only comes up if the negotiation process succeeds in finding a common mode between the Cisco 7201 RJ-45 media type and its link partner.

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

For information on flow control, see the Cisco 7201 Installation and Configuration Guide, Appendix A, "Gigabit Ethernet Flow Control Information" section.

Debug Information

Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is 0, 1, 2, or 3) and show controllers GigabitEthernet 0/X (where X is 0, 1, 2, or 3).

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 controllers command displays more information specific to the Cisco 7201 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 controllers command also displays the current operating state of the driver and the Ethernet controller hardware. The show controllers 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 you want to try and reset it, use the command:

clear interface GigabitEthernet 0/X (where X is 0, 1, 2, or 3)

Clear Counters

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

clear counters GigabitEthernet 0/X (where X is 0, 1, 2, or 3)

Note Using this command will not reset the interface.
