Rear View

Figure 1-4 Cisco 7301—Rear View

Five internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. (See Figure 1-4.) The five fans are located at the rear of the chassis as is the chassis grounding connector that provide a chassis ground connection for ESD equipment or a t

wo-hole grounding lug.

System Board

Internally, the system board contains the following components:

• Two SODIMM DDR-SDRAM memory modules that are available in three options: 128 MB,

256 MB, and 512 MB

• BCM 1250 processor system

• BCM 1250 integrated dual processor that operates at an internal clock speed of 700 MHz. The

BCM 1250 processor maintains and executes the system management functions for the Cisco 7301 ro

uter. The processor also performs some memory and environmental monitoring functions.

–

The BCM 1250 serves as the system controller. It interconnects the processor with the double data rate synchronous dynamic random-access memory (DDR-SDRAM) controller, lightning data transport (LDT) bus, and the three direct-interface Gigabit Ethernet interfaces, and the port adapter PCI bus, which allows the port adapter access to DDR-SDRAM.

• Cache memory

The processor system has two levels of cache: primary and secondary cache that are internal to the mi

croprocessor with secondary unified cache for data and instruction.

• Three Gigabit Ethernet interfaces: (six ports: three SFP GBIC [optical] and three RJ-45s [copper]).

Any three ports are available at the same time and are linked directly to the BCM 1250 system.

• A CompactFlash Disk for storing the default Cisco IOS software image.

• Auxiliary port with full data terminal equipment (DTE) functionality.

• Boot ROM for storing sufficient code for booting the Cisco IOS software.

• Flash memory for storing the boot helper (boot loader) image.

–

One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately

0.108-inch (2.743-mm) insulation, for a total wire diameter of approximately 0.27 inches (6.858 mm). The wire length depends on your router location and site environment.

The rack-mount and cable-management kit includes the following parts:

• Two rack-mount brackets for mounting the chassis in the rack

• One cable-management bracket

• One AC power cable-retention clip (if you ordered a single AC power supply)

• Four 12-24 x 0.5-in. screws to secure the rack-mount brackets to the chassis

• Four 8-18 x .37-in. screws to secure the rack-mount brackets to a 19-inch rack

• Four 8 x .375-in. screws to secure the rack-mount brackets to a 21–23-inch rack

• One M4 x 20-mm screw to attach the cable-management bracket to the rack-mount bracket

In addition, you might need the following external equipment:

• Data service unit (DSU) to connect each serial port to an external network

• T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link

Control (HDLC) synchronous serial data stream into a T1 data stream with the correct framing and ones density to connect a serial port to a T1 network. (Some telephone systems require a minimum number of 1 bits per time unit in a data stream, called ones density.) Several T1 CSU/DSU devices are available as additional equipment, and most provide a V.35, EIA/TIA-449, or EIA-530 electrical interface.

• Ethernet transceiver

• Token Ring multistation access unit (MSAU)

• ESD-preventative wrist strap

• Power cord

• Appropriate cables to connect the router to the console and auxiliary ports

Electrical Equipment Guidelines

The port adapter is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent system failures. Each port adapter consists of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the carrier helps protect the boards, use an antistatic strap whenever handling the port adapter. Handle the carriers by the handle and the carrier edges only; never touch the boards or connector pins.

Site Requirement Guidelines

Warning

Before you install, operate, or service the system, read the “Site Preparation and Safety Information” section of the Cisco 7301 Series Internet Routers Regulatory Compliance and Safety Information document. This section contains important safety information you should know before working with the system.

Statement 200

The environmental monitoring functionality in the Cisco 7301 router protects the system and components from potential damage from overvoltage and overtemperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure the site maintains an ambient temperature of 32•F through F through 104•F (0•C through 40•C), and keep the area around the chassis as free from dust as is practical. F (0•C through 40•C), and keep the area around the chassis as free from dust as is practical.

Planning a proper location for the Cisco 7301 router and the layout of your equipment rack or wiring cl

oset is essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance difficult. Following are precautions that can help avoid problems during installation and ongoing operation.

Figure 2-2 Airflow Through the Chassis

When you plan the location and layout of your equipment rack or wiring closet, you need to consider how air flows through your router. The Cisco 7301 router draws cooling air in through the intake vents on the front of the chassis and moves the air across the internal components and out the exhaust vents on the rear of the chassis. Figure 2-2 shows airflow through the router.

Temperature sensors on the system board monitor the internal air temperature and send warning m

essages when the internal air temperature approaches a specified threshold. If the internal temperature exceeds the specified threshold, the system environmental monitor shuts down all internal power to prevent equipment damage from excessive heat. (See the “Environmental Monitoring and Reporting

Functions” section on page 3-5 for temperature threshold information.)

Installing the Router

This section explains how to install a Cisco 7301 router in a general tabletop or workbench installation and in a rack, and how to attach I/O, port adapter, and power cables. This section contains the following topics:

• Installing the Chassis in the Rack, page 2-9

General Tabletop or Workbench Installation

The router should already be in the area where you will install it, and your installation location should already be determined. If not, see the “Preparing to Install the Cisco 7301 Router” section on page 2-1, and the “Site Requirement Guidelines” section on page 2-4.

When installing a Cisco 7301 router on a workbench or tabletop, ensure that the surface is clean and in a

safe location and that you have considered the following:

• The router requires at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (the front

and back sides of the router).

• The router should be installed off the floor. (Dust that accumulates on the floor is drawn into the

interior of the router by the cooling fans. Excessive dust inside the router can cause overtemperature conditions and component failures.)

• There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the router for

installing and replacing router parts—such as the port adapter, SFP GBIC module, or CompactFlash Disk—or accessing network cables or equipment.

• A blank port adapter is installed if a port adapter or service adapter is not in place.

• The router will receive adequate ventilation (it is not being installed in an enclosed cabinet where

ventilation is inadequate).

• If you plan to install the cable-management bracket, unpack and have handy the cable-management

bracket and one M4 x 20-mm screw.

• An adequate chassis ground (earth) connection exists for your router chassis.

Warning

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).

Statement 13

Following are the steps for installing a Cisco 7301 router on a workbench or tabletop:

Step 1 Remove any debris and dust from the tabletop or workbench, as well as the surrounding area. Also make

sure your path between the router and its new location is unobstructed.

Step 2 On the chassis, ensure that the port adapter latch is in the locked position. Step 3 Lift the chassis by placing your hands around the chassis sides and lifting the chassis from underneath.

To prevent injury, avoid sudden twists or moves.

Step 4 Place the router on the tabletop or workbench. Step 5 Ensure that there is at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents of the router

and no exhaust air from other equipment will be drawn into the chassis. Also, ensure that there is approximately 19 inches (48.3 cm) of clearance at the front and rear of the chassis.

This completes the general tabletop or workbench installation.

Chapter 2 Rack-Mounting, Tabletop Installation, and Cabling

Installing the Router

Rack-Mounting a Cisco 7301 Router

The chassis mounts to two rack posts with brackets that attach to either the front or the rear sides of the chassis. The inside width between the two posts or mounting strips (left and right) must be at least 17.3 inches (43.9 cm).

Some equipment racks provide a power strip along the length of one of the mounting strips. Figu

re 2-7

shows a typical four-post equipment rack with a power strip along one of the back posts. If your rack has th

is feature, consider the position of the strip when planning fastener points to ensure that you will be able to pull the port adapter, SFP GBIC module, or CompactFlash Disk straight out of their respective slots.

The inlet and exhaust ports for cooling air are located on the front and rear of the chassis, respectively, so

multiple routers can be stacked in a rack with little or no vertical clearance.

Before beginning the installation, determine the type of rack you are using and whether or not you want th

e chassis front- or rear-mounted.

Note If you are rear-mounting the chassis and want to use the cable-management bracket, you must purchase

a second rack-mount kit. You need another rack-mount bracket to attach to the front of the chassis. After it is attached to the chassis, install the cable-management bracket to the rack-mount bracket.

Attaching the Chassis Rack-Mount and Cable-Management Brackets

This section explains how to install the rack-mount and cable-management brackets at the front and the rear of a Cisco 7301 router. Before installing the chassis in the rack, you must install a rack-mount bracket on each side of the front or rear of the chassis.

The parts and tools required for installing the rack-mount brackets and cable-management bracket are li

sted in the “Tools and Parts Required” section on page 2-2.

Step 1 Locate the threaded holes in the rear sides of the chassis. Step 2 Align the rack-mount bracket to the side of the router. Depending on which set of holes on the

rack-mount bracket that you use, the router will either be recessed in the rack or protrude from the rack.

Step 3 Insert and tighten the two screws. Step 4 Repeat Step 1 through Step 3 on the other side of the router.

Note To use the cable-management bracket with the Cisco 7301 router rear-mounted, you must purchase a

second rack-mount kit, attach a rack-mount bracket to the left front of the chassis, and attach the cable-management bracket to it. See the “Attaching the Cable-Management Bracket” section on page 2-8 for cable-management bracket installation instructions.

This completes the procedure for installing the rack-mount and cable-management brackets on a Cisco 7301 router for a rear rack-mount configuration. Go to the “Installing the Chassis in the Rack” section

on page 2-9.

Installing the Chassis in the Rack

Caution To prevent injury, review the safety precautions in this chapter before installing the router in a rack.

After installing the brackets on the chassis, you mount the router by securing the rack-mount brackets to t

wo posts or mounting strips in the rack using the four screws provided. Because the brackets support the weight of the entire chassis, be sure to use all four screws to fasten the two rack-mount brackets to the rack posts. Figure 2-6 on page 2-10 and Figure 2-7 on page 2-11 show typical installations in two-post and four-post equipment racks.

We recommend that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the ro

uter and any equipment directly above and below it.

To install the chassis in the rack, complete the following steps:

Step 1 On the chassis, ensure that the port adapter latch is in the locked position and tightened, and that the

CompactFlash Disk and any SFP GBIC modules are installed.

Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are

engaged or that the rack is otherwise stabilized.

Step 3 Position the chassis so that the front end is closest to you. Lift the chassis and move it to the rack. To

prevent injury, avoid sudden twists or moves.

Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the

chassis) meet the mounting strips or posts on both sides of the equipment rack.

For two-post rack installation, go to the “Two-Post Rack Installation” section on page 2-10.

Attaching a Chassis Ground Connection

Before you connect power or turn on power to your router, we strongly recommend that you provide an adequate chassis ground (earth) connection for the router chassis. Chassis ground connectors are provided on each Cisco 7301 router chassis. (See Figure 2-8 on page 2-12.)

To ensure the chassis ground connection that you provide is adequate, you will need the following parts an

d tools:

• One grounding lug—Must have two number-10 screw holes that have a 0.63-inch (16.002-mm)

spacing between them, and a wire receptacle large enough to accept a 6-AWG multistrand, copper

wire. This grounding lug is not available from Cisco Systems; electrical-connector vendors provide

this type of grounding lug.

• Two Phillips machine screws with locking washers—M5 (metric), 0.031-inch (0.8-mm) pitch,

0.315-inch (8-mm) length. These screws are not available from Cisco Systems; they are available

from a commercial hardware vendor.

• One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108-inch

(2.743-mm) insulation, for a total wire diameter of approximately 0.27 inches (6.858 mm). The wire

ength is dependent on your router location and site environment. This wire is not available from

Cisco Systems; it is available from a commercial cable vendor.

• Number 2 Phillips screwdriver

• Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding

lug

• Wire stripper

Connecting Port Adapter Cables

The instructions for connecting the cables for the port adapter installed in the Cisco 7301 router are contained in the respective configuration notes for each port adapter. For example, if you are connecting the optical fiber cables for the PA-POS-OC3 port adapter, refer to the configuration note PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration at

http://www.cisco.com/univercd/cc/td/doc/product/core/7206/port_adp/sonet_pa/paposoc3/index.htm.

Port adapter documents are also available on the Documentation CD-ROM.

Connecting I/O Cables

This section contains connection equipment information for the Gigabit Ethernet, console, and auxiliary ports.

Warning

The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

Statement 22

Connecting Console and Auxiliary Port Cables

Note The console cable kit product number is ACS-2500ASYN.

The Cisco 7301 router has a DCE-mode console port for connecting a console terminal, and a DTE-mode a

uxiliary port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your

router.

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these

ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The Cisco 7301 router uses RJ-45 ports for both the auxiliary port and console port.

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, 1 stop bits (9600 8N1). After you establish normal router

operation, you can disconnect the terminal.

For console and auxiliary port pinouts for the RJ-45 connector, see A

Connecting I/O Cables

Refer to Table 2-2 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 7301 router. The cable you use may be a roll-over cable or

a straight 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 2-10.)

Figure 2-10 Identifying a Roll-Over Cable

The Cisco 7301 router ships with a rolled cable. Connection to a terminal or a modem will require an RJ-45-to-DB-25 adapter, and possibly a DB-25-to-DB9 adapter. Refer to Ta ble 2-3 for the cable and adapter configurations that can be used to connect terminals and modems to the Cisco 7301 router.

The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables with RJ-45 connectors. Cisco Systems does not supply Category 5 UTP cables; these cables are available commercially.

See A

ppendix A, “Specifications,” for Gigabit Ethernet RJ-45 port specifications.

Intra-Building Lightning Protection

Shielded cables, which are grounded at both ends, are required to be used on the 10/100/1000 Ethernet (RJ-45) 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.

Step 1 Remove the plug from the SFP GBIC module so that you can insert the 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 GBIC module. You can use either simplex

or duplex connectors for most devices. (Figure 2-13 shows a SFP GBIC module with a duplex connector being installed in SFP GBIC slot 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.

A mode-conditioning patch cord can be used with the GLC-LH-SM to allow reliable laser transmission between the single-mode laser source on the SFP GBIC module and a multimode optical fiber cable. For installation instructions, see the

“Attaching the Mode-Conditioning Patch Cord” section on page 2-19.

Attaching the Mode-Conditioning Patch Cord

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

When an unconditioned laser source designed for operation on single-mode optical fiber is directly c

oupled 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) th

at 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.

Connecting I/O Cables

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 2-14) to a graded-index multimode optical fiber. Figure 2-14 shows a diagram of the mode-conditioning patch cord assembly.

Figure 2-14 SFP Mode-Conditioning Patch Cord

Note Figure 2-14 shows one type of mode-conditioning patch cord.

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

Step 1 Attach a patch cord to the SFP GBIC module. (See Figure 2-13.) Step 2 Attach the network ends of your 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 (r

espectively) on the other end. Connect TX to RX and RX to TX.

This completes the procedures for connecting the I/O cables.

Attaching the Alarm Port Cable

Figure 2-15 Connecting the Alarm Port Cable

If you have an alarm system, attach the alarm cable to the Cisco 7301 router alarm port. The alarm port cable is not provided by Cisco Systems. Insert the cable connector into the alarm port. The cable connector cannot be incorrectly inserted into the alarm port.

The alarm port is used to monitor fatal or severe errors that cause Cisco IOS to crash. The alarm port is c

onnected to a normally closed solid state relay. Cisco IOS writes to a hardware port and the relay

ontact opens. If the system enters into a ROMmon or watchdog reset state, the relay contacts close. The

closing contacts alert the alarm annunciator or monitor that a Cisco IOS crash has occurred.

If interfaces fail or other non-fatal errors occur, the alarm port does not respond. Continue to use SNMP t

o manage these types of errors.

For alarm port specifications, see A

Chapter 3 Starting and Configuring the Router

Functional Overview

Chassis Slot and Logical Interface Numbering

In the Cisco 7301 router, the port-adapter-slot-number is the chassis slot in which a port adapter is installed, whereas the logical-interface-number is the physical location of the interface port on a port adapter.

The port adapter slot in the Cisco 7301 router is numbered slot 1. Port adapter slot 0 is always reserved fo

r logical ports 10/100/1000.

The Media Access Control (MAC) or hardware address is a standardized data link layer address that is re

quired for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The Cisco 7301 router uses a specific method to assign and control the MAC addresses of its port adapters. For a description of the MAC address, see the

“MAC Address” section on page 3-3.

You can identify port adapter slots by using software commands. To display information about all port ad

apter slots, use the show interfaces command. To display information about a specific port adapter

slot, use the show interfaces command with the port adapter type and slot number in the format

show interfaces port

-adapter-type slot-number/port-number. If you abbreviate the command (sh int)

and do not specify port adapter type and slot number (or arguments), the system interprets the command as show interfaces and displays the status of all port adapters and ports.

The following example shows how the s

how interfaces command, used without arguments, displays status information (including the physical port adapter number) for the port adapter in a Cisco 7301 router.

In the following example, most of the status information for each interface is omitted.

MAC Address

All LAN interfaces (ports) require unique MAC addresses, also known as hardware addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the OIR feature requires a different method. (For a description of OIR, see the

“Online Insertion and Removal” section on page 3-4.)

Using OIR, you can remove a port adapter and replace it with another identically configured one. If the ne

w port adapter matches the port adapter you removed, the system immediately brings it online. In order to enable OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the system board. Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot. The MAC address for the port adapter slot in the Cisco 7301 is slot 0. You can remove a port adapter and insert it into another router without causing the MAC addresses to move around the network or be assigned to multiple devices.

3-4

Cisco 7301 Installation and Configuration Guide

OL-5418-07

Chapter 3 Starting and Configuring the Router

Functional Overview

Note that if the MAC addresses were stored on each port adapter, OIR would not function because you could never replace one port adapter with an identical one; the MAC addresses would always be different. Also, each time a port adapter was replaced, other devices on the network would have to update their data structures with the new address. If the other devices did not update quickly enough, the same MAC address could appear in more than one device at the same time.

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the

memory device on which they are stored.

Online Insertion and Removal

All port adapters and service adapters in the Cisco 7301 routers support online insertion and removal (OIR). However, it is wise to shut down the interface before removing a port adapter that has active traffic moving through it. Removing a port adapter while traffic is flowing through the ports can cause system disruption. Once the port adapter is inserted, the ports can be brought back up.

Note As you disengage the port adapter from the router or switch, online insertion and removal (OIR)

administratively shuts down all active interfaces in the port adapter.

OIR allows you to install and replace port adapters and service adapters while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific pr

ocedures for installing and replacing a port adapter or service adapter in a Cisco 7301 router, refer to

the online configuration note for each port adapter or service adapter.

Each port adapter or service adapter has a bus connector that connects it to the router. The connector has a

set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter or service adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter or service adapter is being removed or inserted into the system. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface.

For example, when you insert a port adapter or service adapter, the longest pins make contact with the p

ort adapter or service adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter or service adapter in a Cisco 7301 router, the pins send signals to

notify the system, which then performs as follows:

1. Rapidly scans the system for configuration changes.

2. Initializes all newly inserted port adapters or service adapters, noting any removed interfaces and

placing them in the administratively shutdown state.

3. Brings all previously configured interfaces on the port adapter back to the state they were in when

they were removed. Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the original port adapter. (A service adapter has no configurable ports.)

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation. The environmental monitoring functions constantly monitor the internal chassis air temperature and DC supply voltages and currents. If conditions reach shutdown thresholds, the system shuts down to avoid equipment damage from excessive heat. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.

Environmental Monitoring

The environmental monitoring functions use two sensors, Sensor 1 (U62) on the underneath front edge of the system board, and Sensor 2 (U5), near the fans. If the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system. The system stores the present parameter measurements for both temperature and DC voltage in NVRAM so you can retrieve them later as a report of the last shutdown parameters.

If an internal power supply temperature or voltage reaches a critical level, the power supply shuts down wi

thout any interaction with the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the syste

• Normal—All monitored parameters are within normal tolerances.

• Warning—The system has exceeded a specified threshold. The system continues to operate, but

operator action is recommended to bring the system back to a normal state.

• Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to

operate; however, the system is approaching shutdown. Immediate operator action is required.

• Shutdown—The processor has detected a temperature condition that could result in physical damage

to system components and has disabled DC power to all internal components. This condition requires immediate operator action. All DC power remains disabled until you toggle the power switch. Before any shutdown, the system logs the status of monitored parameters in NVRAM so you can retrieve it later to help determine the cause of the problem.

• Power supply shutdown—The power supply detected an internal out-of-tolerance overvoltage,

overcurrent, or temperature condition and shut itself down. All DC power remains disabled until you toggle the power switch.

Table 3-1 lists th

e typical temperature thresholds for the Cisco 7301 router, and Tab le 3-2 lists the DC

power thresholds for the normal, warning, and critical (power supply-monitored) levels.

Functional Overview

Note Table 3-2 shows output from the show environment table command.

Reporting Functions

The Cisco 7301 router displays warning messages on the console if chassis interface-monitored parameters exceed a desired threshold. You can also retrieve and display environmental status reports with the show environment, show environment all, show environment last, and show environment table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows.

Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature

conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.

The show environment command displays reports of the current environmental system status. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within normal range:

Router# show environment

All measured values are normal

If the environmental status is not normal, the system reports the worst-case status level. Following is a sample overvoltage warning:

Router# show environment

Warning:+3.45 V measured at +3.27 V

The show environment last command retrieves and displays the NVRAM log, which shows the reason for the last system shutdown (if the shutdown was related to voltage or temperature) and the environmental status at that time. Air temperature is measured and displayed, and the DC voltage supplied by the power supply is also displayed.

For complete descriptions and instructions for the environmental monitor commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications, which are available online.

Checking Conditions Prior to System Startup

Check the following conditions before you start your router:

• The port adapter is inserted in its slot and the port adapter latch is in the locked position.

• The network interface cable is connected to the port adapter.

• A CompactFlash Disk is installed.

• The console terminal is turned on.

You are now ready to start your router. Proceed to the section “Sta

rting the System and Observing Initial

Conditions.”

Chapter 3 Starting and Configuring the Router

Starting the System and Observing Initial Conditions

After installing your Cisco 7301 router and connecting cables, start the router as follows:

Step 1 At the front of the router, place the power switch on the power supply in the on (|) position. Step 2 Listen for the fans; you should immediately hear them operating. Step 3 During the boot process, observe the system LEDs. The LEDs on the port adapter go on and off in

irregular sequence. They may go on, go out, and go on again for a short time. On the router, the green STATUS LED comes on and stays on.

Step 4 Observe the initialization process. When the system boot is complete (a few seconds), the processor

begins to initialize the port adapter and the I/O subsystem. During this initialization, the LEDs on the port adapter probably will flash on and off.

The enabled LED on the port adapter goes on when initialization is completed, and the console screen di

splays a script and system banner similar to the following:

Step 5 When you start up the router for the first time, the system automatically enters the setup facility, which

determines which port adapter is installed and prompts you for configuration information. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt:

--- System Configuration Dialog ---

At any point you may enter a questions mark ‘?’ for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets ‘[]’.

continue with configuration dialog? [yes]:

You have the option of proceeding with the setup facility to configure the interfaces, or exiting from setup and using configuration commands to configure global (system-wide) and interface-specific parameters. 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.

Many of the port adapter LEDs do not go on until you have configured the interfaces. To verify correct operation of each interface, complete the first-time startup procedures and configuration, and then refer to the configuration note for the port adapter for LED descriptions and to check the status of the interfaces.

If the system does not complete each of the steps in the startup procedure, proceed to Cha

pter 5,

Chapter 3 Starting and Configuring the Router

Configuring a Cisco 7301 Router

Before configuring the router, determine whether or not you want to use a management tool such as Cisco Security Device Manager.

Cisco Security Device Manager (SDM), version 1.1, is an optional Java-based device-management tool th

at allows you to configure LAN interfaces, routing, Network Address Translation (NAT), firewalls, Virtual Private Networks (VPNs), and other features without knowledge of the Cisco command-line interface (CLI). You can configure features such as Access Control Lists (ACLs), routing protocols, and other options using the advanced mode SDM.

Note You will need to use CLI commands to configure several features that SDM does not support. SDM does

not support the following features: WAN configuration, Gigabit Ethernet (GE) interfaces, AA client, EZ VPN server, QoS, SSHv2, DHCP server configuration options, and usability enhancements.

SDM is preinstalled on your router’s flash disk or compactflash disk when it is ordered as part of a VPN bundle or as part of a 7xxx VPN bundle. If your router did not ship with SDM preinstalled, you can download a free copy from the Software Center at Cisco.com at

http://ww.cisco.com/kobayashi/sw-center/index.shtm. Because SDM uses a GUI, it requires that you

access it from a PC using a supported web browser. Go to the Cisco Router and Security Device Manager

(SDM) User Guide for the Cisco 7200 VXR and Cisco 7301 Routers d

ocumentation for more information.

You can configure your Cisco 7301 router using one of the procedures described in the following se

ctions:

• Performing a Basic Configuration Using AutoInstall, page 3-10

• Performing a Basic Configuration Using the Setup Facility, page 3-11

• Performing a Basic Configuration Using Global Configuration Mode, page 3-20

Follow the procedure that best fits the needs of your network configuration.

Note You need to acquire the correct network addresses from your system administrator or consult your

network plan to determine correct addresses before you can complete the router configuration.

Before continuing the configuration process, check the current state of the router by entering the show version command. The show version command displays the release of Cisco IOS software that is available on the router. Sample output of the show version command appears in the “Viewing Your

System Configuration” section on page 3-34.

Performing a Basic Configuration Using AutoInstall

The AutoInstall process is designed to configure the Cisco 7301 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.

3-11

Cisco 7301 Installation and Configuration Guide

OL-5418-07

Chapter 3 Starting and Configuring the Router

Configuring a Cisco 7301 Router

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 7301 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 (|) 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 co

nnection is connected and properly configured, the AutoInstall process begins.

Once the AutoInstall process is completed, use the c

opy 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 3 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.

Performing 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 sto

red 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.

Configuring 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:

Configuring the Native Gigabit Ethernet Interfaces

The Cisco 7301 router reports the Gigabit Ethernet RJ-45 and SFP GBIC ports as GigabitEthernet 0/0, GigabitEthernet 0/1, and GigabitEthernet0/2. Before configuring any of the three interfaces, you must first use the media-type interface command to select the media type, either gbic 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 { gbic | rj45 }

Example:

interface GigabitEthernet 0/0

media-type rj45

end

3-15

Cisco 7301 Installation and Configuration Guide

OL-5418-07

Chapter 3 Starting and Configuring the Router

Configuring a Cisco 7301 Router

Configuring the Interface Transmission and Speed Modes

Step 1 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 7301 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, 1000, auto full, half, auto GBIC(1) 1000, auto(2) full, half, auto

-------------------------------------------------------------

a. If you are using the no negotion auto command, the speed and duplex should be set to a value other

than auto for correct operation.

b. The only available speed in this mode is 1000 Mbps; there is no difference whether 1000 or auto is

selected.

When using the SFP GBIC media, there is also the additional ne

gotiation auto command that is used to

enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

Step 2 To turn this autonegotiation 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.

Note The negotiation auto feature is not supported when using the media type rj-45 and will be

ignored if implementation is attempted.

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 mode, even if present in the configuration (for an example, see output from show running-config).

Debugging

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

1, or 2).

The output of the sho

w 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 s

how controller command displays more information specific to the Cisco 7301 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).

Configuring a Cisco 7301 Router

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.

Resetting 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, or 2)

Clearing Counters

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

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

Note Using this command will not reset the interface.

Configuring 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.

Note Only one port adapter can be installed in the Cisco 7301 at one time. Following are three examples of

three different interfaces that might be used.

Configuring 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:

Configuring interface parameters:

Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network

number:

Configure IPX on this interface? [no]: yes IPX network number [2]:

Performing a Basic Configuration Using Global Configuration Mode

You can configure a Cisco 7301 router manually if you prefer not to use the setup facility or AutoInstall. Complete the following steps to configure the router manually:

Step 1 Connect a console terminal to the console port. Step 2 When asked if you want to enter the initial dialog, answer no to go into the normal operating mode of

the router:

Would you like to enter the initial dialog? [yes]: no

Step 3 After a few seconds the user EXEC prompt (Router>) is displayed. Type enable to enter enable mode

(configuration changes can only be made in enable mode):

Router> enable

The prompt changes to the privileged EXEC prompt:

Router#

Step 4 Enter the config terminal command at the enable prompt to enter configuration mode from the terminal:

Router# config terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

At the Router(config)# prompt, enter the interface type slot/port command to enter the interface configuration mode:

Router(config)# interface serial

slot/port

Router(config-int)#

In either configuration mode, you can now enter any changes to the configuration. Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter.

Step 5 Save your settings to NVRAM, or if you are enabling the second processor, see “Enabling the Second

Processor” section on page 3-20. (See the “Saving the Running Configuration to NVRAM” section on page 3-27.) 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 ro

uter.

Your router is now minimally configured and will boot with the configuration you have entered. To see a list of the configuration commands available to you, enter ? at the prompt while in configuration mode.

Enabling the Second Processor

The Cisco 7301 includes a dual-CPU-core BCM 1250. All Cisco IOS images for the Cisco 7301 platform use CPU-core 0. CPU-core 1 allows acceleration of specific feature sets via separately purchased special software. As of Cisco IOS Release 12.3(14)YM, multi-processor forwarding (MPF) accelerates the following broadband features: L2TP Access Concentrator (LAC), L2TP Network Server (LNS), and PPP Terminated Aggregation (PTA). Port adapters are not supported in the multi-processor forwarding (MPF) path on processor 1.

You may have purchased the enabling software when you purchased a new chassis or you may have p

urchased the software as an upgrade.

If you are purchasing the software as an upgrade, you must:

• Upgrade the ROMmon if you do not have the minimum ROMmon version.

–

The minimum ROMmon version is 12.3-4r.T2.

–

The recommended ROMmon version is 12.3-4r.T4 or higher.

• Install the enabling software.

Instructions for upgrading ROMmon are in the “U

pgrading ROMmon on the Cisco 7301” section on

page 3-27.

The software releases associated with enabling the second processor are listed in Ta

ble 3-3.

Also see the Mu

lti-Processor Forwarding (MPF) for Broadband LAC document for minimum memory

requirements and configuration information.

Note Before enabling the second processor, you must have IP routing turned on.

Processor 1 is enabled by default after you install the enabling software. To have all packets forwarded b

y processor 0, use the no ip mpf command. To enable processor 1, use the ip mpf command.

hostname: (config)# [no] ip mpf

Saving the Running Configuration to NVRAM

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-config startup-config command at the

Router# prompt:

Router# copy running-config startup-config

Using this command saves the configuration settings that you created in the router using configuration mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload the router.

Checking the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-config command at the

Router#

prompt:

Router# show running-config

To review changes you make to the configuration, use the EXEC mode show startup-config command to display the information stored in NVRAM.

Performing Other Configuration Tasks

To make advanced configuration changes after you establish the basic startup configuration for your router, refer to the modular configuration and modular command reference publications in the Cisco IOS so

ftware configuration documentation set that corresponds to the software release installed on your

Cisco hardware. These publications contain additional information on using the configure command.

The configuration publications also provide information about the following tasks:

• Understanding and working with the user interface on your router

• Booting and rebooting the router

• Setting the configuration register

• Loading configuration files or system images using remote copy protocol (rcp) or Trivial File

Transfer Protocol (TFTP)

• Reloading the operating system

Upgrading ROMmon on the Cisco 7301

Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image instead of having to replace hardware (Cisco 7301) to get a new image.

There are two ROMmon images: the ReadOnly image that ships with your system (and is always av

ailable if you have Cisco 7301 hardware EPROM Version 1.4 and software C7301:Rommon version is

12.3(4r)T2 or later), and the upgradable ROMmon image that is downloaded from a specified TFTP file location. You can choose to configure the system to point to the upgradable ROMmon image. At bootup, the system starts with the ReadOnly image and then, if configured, jumps to the upgradeable ROMmon image. If the upgradeable ROMmon image fails to boot, the router will mark this ROMmon image as invalid and reverts to the ReadOnly ROMmon image.

3-28

Cisco 7301 Installation and Configuration Guide

OL-5418-07

Chapter 3 Starting and Configuring the Router

Upgrading ROMmon on the Cisco 7301

The first time a new ROMmon image is executed, you must allow the system to boot ROMmon before doing any additional resets or power cycling. If the ROMmon-executing process is interrupted, the system interprets this as a bootup failure of the new ROMmon image. The router reverts to the ReadOnly image.

Note The ROMmon upgradeable image is marked as invalid if it fails to boot. Do not reset the router when it

is doing an initial bootup.

Using the show rom-monitor Command and showmon Commands

Use the show rom-monitor command if you are in Cisco IOS, or the showmon command if you are in ROMmon, to determine which ROMmon images are available. See the following examples for information shown in the output of the show rom-monitor or showmon commands:

• If you are in Cisco IOS, use the show rom-monitor command:

Router> show rom-monitor ReadOnly ROMMON version:

Upgrade ROMMON version:

Currently running ROMMON from Upgrade region ROMMON from Upgrade region is selected for next boot

• If you are in ROMmon, use the showmon command:

rommon 1 > rommon CLI showmon

Upgrade ROMMON currently running Upgrade ROMMON is selected for next boot rommon 2 >

Using the upgrade rom-monitor Command

Use the upgrade rom-monitor file file_id command to program the ROMmon.

See the following example of the upgrade r

om-monitor command:

Router# upgrade rom-monitor file tftp://00.0.00.0/biff/C7301_c7301-is-mz Loading pgettner/C7200_NPEG1_RMFUR.srec from 00.0.00.0 (via GigabitEthernet0/1): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! [OK - 392348 bytes]

Changing Preferences to Choose the Other ROMmon Image

To use the other ROMmon image, use one of the following commands to make the change depending on whether you are in Cisco IOS or in ROMmon:

• In Cisco IOS, use the upgrade rom-monitor preference command to change to the other ROMmon

image:

upgrade rom-monitor preference [readonly | upgrade]

Example:

Router: upgrade rom-monitor preference readonly You are about to mark ReadOnly region of ROMMON for the highest boot preference. Proceed? [confirm] Done! Router must be reloaded for this to take effect.

• In ROMmon, use the ROMmon CLI rommon-pref command to change to the other ROMmon

Chapter 3 Starting and Configuring the Router

Replacing or Recovering a Lost Password

This section describes how to recover a lost enable or console login password, and how to replace a lost enable secret password on your Cisco 7301 router.

Note It is possible to recover the enable or console login password. The enable secret password is encrypted,

however, and must be replaced with a new enable secret password.

Overview of the Password Recovery Procedure

Following is an overview of the steps in the password recovery procedure:

Step 1 If you can log in to the router, enter the show version command to determine the existing configuration

Step 2 Press the Break key to get to the bootstrap program prompt (ROM monitor). You might need to reload

the system image by power cycling the router.

Step 3 Change the configuration register so the following functions are enabled:

a. Break b. Ignore startup configuration c. Boot from Flash memory

Note The key to recovering a lost password is to set the configuration register bit 6 (0x0040) so that

the startup configuration (usually in NVRAM) is ignored. This allows you to log in without using a password and to display the startup configuration passwords.

Note When powering off the router, wait 30 seconds before powering it on again.

Step 4 Power cycle the router by turning power off and then back on. Step 5 Log in to the router and enter the privileged EXEC mode. Step 6 Enter the show startup-config command to display the passwords. Step 7 Recover or replace the displayed passwords. Step 8 Change the configuration register back to its original setting.

Note To recover a lost password if the Break function is disabled on the router, you must have physical access

to the router.

Chapter 3 Starting and Configuring the Router

Replacing or Recovering a Lost Password

Details of the Password Recovery Procedure

Complete the following steps to recover or replace a lost enable, enable secret, or console login password:

Step 1 Attach an ASCII terminal to the console port on your router. Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit (9600 8N1). Step 3 If you can log in to the router as a nonprivileged user, enter the show version command to display the

existing configuration register value. Note the value for use later and proceed to Step 6. If you cannot log in to the router at all, go to the next step.

Step 4 Press the Break key or send a Break from the console terminal. If Break is enabled, the router enters the

ROM monitor, indicated by the ROM monitor prompt (

rommon1>). Proceed to Step 6. If Break is disabled,

power cycle the router (turn the router off or unplug the power cord, and then restore power after waiting 30 seconds). Then proceed to Step 5.

Step 5 Within 60 seconds of restoring the power to the router, press the Break key or send a Break. This action

causes the router to enter the ROM monitor and display the ROM monitor prompt (

rommon1>).

Step 6 Set the configuration register using the configuration register utility; enter the confreg command at the

ROM monitor prompt as follows:

rommon1> confreg

Step 7 Answer yes to the enable “ignore system config info?” question, and note the current configuration

Step 8 Initialize the router by entering the reset command as follows:

rommon2> reset

The router initializes, the configuration register is set to 0x142, and the router boots the system image from Flash memory and enters the System Configuration Dialog prompt as follows:

--- System Configuration Dialog --

Step 9 Enter no in response to the System Configuration Dialog prompts until the following message is

displayed:

Press RETURN to get started!

Step 10 Press Return. The user EXEC prompt is displayed as follows:

Router>

Step 11 Enter the enable command to enter privileged EXEC mode. Then enter the show startup-config

command to display the passwords in the configuration file as follows:

Router# show startup-config

Step 12 Scan the configuration file display looking for the passwords (the enable passwords are usually near the

beginning of the file, and the console login or user EXEC password is near the end). The passwords displayed look something like this:

enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei enable password 23skiddoo . . line con 0 password onramp

Chapter 3 Starting and Configuring the Router

Replacing or Recovering a Lost Password

The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console login passwords may be encrypted or clear text. Proceed to the next step to replace an enable secret, console login, or enable password. If there is no enable secret password, note the enable and console login passwords, if they are not encrypted, and proceed to Step 17.

Caution Do not execute the next step unless you have determined you must change or replace the enable, enable

secret, or console login passwords. Failure to follow the steps as shown might cause you to erase your router configuration.

Step 13 Enter the configure memory command to load the startup configuration file into running memory. This

action allows you to modify or replace passwords in the configuration.

Router# configure memory

Step 14 Enter the privileged EXEC command configure terminal to enter configuration mode:

Hostname# configure terminal

Step 15 Change all three passwords using the following commands:

Hostname(config)# enable secret

newpassword1

Hostname(config)# enable password

newpassword2

Hostname(config)# line con 0 Hostname(config-line)# password

newpassword3

Change only the passwords necessary for your configuration. You can remove individual passwords by using the no form of the above commands. For example, entering the no enable secret command removes the enable secret password.

Step 16 You must configure all interfaces to be not administratively shut down as follows:

Hostname(config)# interface gigabitethernet 0/0 Hostname(config-int)# no shutdown

Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces are administratively shut down and unavailable when the router is restarted.

Step 17 Use the config-register command to set the configuration register to the original value noted in Step 3

or Step 8, or to the factory default value 0x2102 as follows:

Hostname(config)# config-register 0x2102

Step 18 Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode

and return to the EXEC command interpreter.

Caution Do not execute the next step unless you have changed or replaced a password. If you skipped Step 13

through Step 16, skip to Step 20. Failure to observe this caution causes you to erase your router configuration file.

Step 19 Enter the copy running-config startup-config command to save the new configuration to NVRAM. Step 20 Enter the reload command to reboot the router. Step 21 Log in to the router with the new or recovered passwords.

This completes the steps for recovering or replacing a lost enable, enable secret, or console login password.

Warning

During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Statement 94

Before removing any port adapter, gracefully shut down the interface so that there is no traffic running through the port adapter when it is removed. Removing a port adapter while traffic is flowing through the ports can cause system disruption.

The Cisco 7301 router supports OIR of the port adapter. However, if you choose to power off the router to

remove or install a port adapter, turn the power switch to the off position and then remove the power cable. After you have replaced the port adapter or inserted a filler panel, replace the power cable and then turn the power switch to the on position.

Note After powering off the router, wait at least 30 seconds before powering it on again.

Follow these steps for inserting and securing a port adapter:

Step 1 Attach an ESD wrist strap between you and an unpainted chassis surface. For wrist straps with a banana

jack, insert the banana jack in its grounding hole (see Figure 4-2) located on the front of the chassis, near the STATUS LED and power switch.

Powering Off the Router and Removing the Cover

Step 2 Remove the port adaper from the chassis slot. Use a Phillips screwdriver to turn the screw holding the

port adapter latch. The screw should be loose enough to allow the latch to rotate to an unlocked position (1). The latch can rotate 360

Step 3 Grasp the handle and pull the port adapter (2) or blank port adapter from the router. Step 4 Disconnect all cables from the port adapter. Step 5 Locate the port adapter slot guides inside the Cisco 7301 router. They are near the top, and are recessed

about one-half inch.

Caution The port adapter must slide into the slot guides under the chassis lid. Do not allow the port adapter

components to come in contact with the system board or the port adapter could be damaged.

Step 6 Carefully slide the port adapter into the port adapter slot and seat it. When installed, the port adapter

input/output panel should be flush with the face of the router.

Step 7 Rotate the port adapter latch to the upright locked position and use a Phillips screwdriver to tighten the

latch screw. Loosen the latch screw, if needed, to be able to rotate the latch over the port adapter. Then tighten the latch screw.

Step 8 Reconnect any cables, including the port adapter and power cables, and place the cables through any

cable-management bracket or power cable-retention clip.

Step 9 Power on the router by turning the power switch to the on position.

This completes the port adapter installation procedure.

Caution To ensure the proper flow of cooling air across the internal components, make sure a port adapter filler

plate is installed in the unoccupied port adapter slot.
