OVERVIEW
The 3Com® Router 3000 series routers provide the following types of interfaces:
■Ethernet interface
■Synchronous/asynchronous serial interface
■Auxiliary (AUX) port
■ISDN BRI S/T and U port
■CT1/PRI port
These features allow you to combine the various technologies, such as PSTN/ISDN, FR (Frame Relay), X.25, leased line, and T1 line, for networking. These multiple interfaces also allow Router 3000 series routers to interoperate with the products of other manufacturers on all levels.
Router 3000 routers use three types of memory:
■ Synchronous Dynamic Random Access Memory (SDRAM) — Saves router operation system software
■ Flash memory — Saves router program files, configuration files and so on
■Boot ROM — Saves boot and initialization programs of the router

PREPARING TO INSTALL THE ROUTER
Safety Warnings
As you prepare to install your router, consider the following safety guidelines:
■Switch off the power supply before connecting the cables.
- Keep the router far away from any heat source.
■To ensure normal heat dissipation, do not stack routers during the installation.
- Do not keep a router in a damp place, and prevent liquid from getting into the router.
■Make sure that the neutral point of the power is grounded properly, to avoid personal injury.
■Make sure that the power is off before plugging or unplugging the interface cards, modules and cables of the router.
■ Before removing the chassis, disconnect all the power cords and external cables.
■To avoid damage to the router, connect all the cables correctly, and never connect telephone cables (including the ISDN lines) to the console or AUX port.
■ During the installation, wear the ESD (Electro-Static Discharge) preventive wrist strap and ESD-preventive gloves. See the Static Electricity section in this chapter for additional information on ESD prevention.
■ 3Com recommends that you use an uninterrupted power supply (UPS) with your router.
■ To enhance the anti-lightning-strike capability of the router, install a power arrester at the front end of the power input, and a special arrester at the input end of the outdoor cable, such as telephone cable, ISDN line or T1/E1 line.
General Site Requirements
The environment of the installation site influences the performance and lifetime of the router. In addition, if the router operates in inappropriate working environment, its performance will become unreliable. The installation site for your router should meet the following requirements for temperature and humidity, dust, gases, static electricity, and electromagnetic discharge.
Temperature and Humidity
To ensure normal operation and to prolong the operational lifetime of the router, the equipment room must maintain adequate temperature and humidity. If the equipment room is damp, it is likely to affect the performance of the insulating material, which may result in electric leakage and lead to metal erosion.
If the equipment room is very dry, the insulating shim will contract, leading to loosening of the fastening screws. In addition, static electricity will be produced, which damages the complementary metal-oxide-semiconductor (CMOS) circuit on
the router. If the equipment is always very hot, the aging process of insulating materials accelerates, which affects the reliability of the router and even its operational lifetime. The requirements for the temperature and humidity of the router installation site are listed in Table 1.
Table 1 Temperature and Humidity Requirements
| Temperature Relative humidity | |
| 0^0 to 40^ ( 32^0 to 104^ ) 5% to 85% |
Dust Dust is harmful to the safe operation of the router. Dust on the chassis can result in static absorption and cause faulty contact between metal connection components or points. Especially when indoor humidity is low, dust is absorbed more easily which not only shortens the operational lifetime of the equipment, but also can result in communication failure. The specifications for the dust content and diameter of the granule within the equipment room are listed in Table 2.
Table 2 Specification for Dust Content
| Maximum diameter (μm) 0.5 | 135 | |||
| Maximum density (the number of granules per cubic meter) | 1.4 × 10^7 | 7 × 10^5 | 2.4 × 10^5 | 1.3 × 10^5 |
Gases Besides the dust specification, the equipment room should also meet strict requirements for the content of salt, acid and sulfide. These harmful gases can accelerate the metal erosion and the aging process of some parts. The presence of harmful gases, such as SO_2 , H_2S , NO_2 , NH_3 , and Cl_2 , should be prevented. The specific limitation values of these harmful gases are given in Table 3.
Table 3 Harmful Gas Limitation Values in Equipment Room
| Gas Average (mg/m) | 3) Maximum (mg/m 3) | |
| SO_2 | 0.2 1.5 | |
| H_2S | 0.0 0.03 | |
| NO_2 | 0.04 | 0.15 |
| NH_3 | 0.05 | 0.15 |
| Cl_2 | 0.01 | 0.3 |
Static Electricity Although careful considerations in preventing electrostatic discharge (ESD) have been taken in the design of the router, if the level of static electricity exceeds a certain threshold, it will cause great damage to the circuit and even to the entire router.
On the communication network connected to the router, the electrostatic induction comes mainly from two aspects: one is from the outside electrical fields, such as the outdoor high-voltage power cable and lightning, and the other is from the inside system, such as indoor environment, floor material and the system structure.
To prevent damage caused by the static electricity, insure that:
■The equipment is grounded
■The equipment room is dust-proof
■Adequate temperature and humidity conditions prevail
■ The operator wears the ESD-preventive wrist strap, ESD-preventive gloves and ESD-preventive clothes while contacting the circuit board.
■The dismantled circuit board is placed upward on the ESD preventive workbench, or put into an ESD preventive bag.
■You avoid holding the outside edge of the circuit board while observing or removing the circuit board, to avoid direct contact with the elements of the circuit board.
Electromagnetic Discharge
All interference sources, whether from outside the router, from the application system, or from inside the router, can damage the router and influence the conduction patterns of capacitance coupling, inductance coupling, electromagnetic wave radiation, common impedance, including the grounding system, coupling and wire, such as power cords, signal cables and output cables.
Take the following precautions:
■ Take effective measures against electrical net interference for power supply system.
■Do not use the working ground of the router together with the grounding device of the power equipment or thunder-proof grounding. Separate them as far as possible;.
- Keep the router away from strong wireless frequencies, radar, and high-current equipment.
■Adopt electromagnetic shielding if necessary.
Preventing Lightning Damage
Although many measures have been taken to protect the Router 3000 series routers from lightning, damage to the router can still happen. To protect your router from lightning, take the following measures:
■Ensure that the PGND wire of the chassis is well grounded
■Ensure that the neutral point in the socket of the AC power supply is well grounded
■ To enhance the lightning protection capability of the power supply, a lightning arrester could be installed at the input end of the power supply
- As for the signal line outdoors to which the interface modules of Router 3000 series routers are connected, such as an ISDN line or telephone line, a special lightning arrester should be installed at the input end of the signal line to enhance the lightning protection capability.
Workbench Requirements
Whether you install the router in a cabinet or directly place it on the workbench, it is necessary to ensure that:
■There is spacing reserved at the air inlet and outlet in the router so as to facilitate the ventilation of the router cabinet.
■ The cabinet and workbench are firm enough to support the weight of the router and other installation accessories.
■The cabinet and workbench are well grounded.
Inspecting the Router and Accessories
After you verify that the installation conditions comply with these requirements, open the packing case of the router and check the contents against the your order contract. Contact your Service representative if you find any discrepancies.
Installation Equipment To install your router, you will need:
■Tools
Phillips screwdriver
Flat-head screwdriver
ESD-preventive wrist strap and ESD-preventive gloves
Flat-blade screws (used in wall mounting)
■Cables

INSTALLING THE ROUTER
There are two ways you can install your router:
■On a vertical surface
■On a workbench
Mounting the Router on a Vertical Surface
The Router 3000 series routers can be mounted onto a vertical surface using 2 pan-head screws and 2 brackets on the base of the router using the following procedure:
1 Mark the bracket positions on the wall.
2 Screw 2 pan-head screws into the marked positions on the wall or the vertical surface, so that the screws match the 2 brackets on the base of the router. Each screw should project 0.6 cm (.25 in) from the wall or the surface.
3 Hang the router on the screws by the two brackets.
4 Make sure that the front panel LEDs are easily visible to the operator
5 Fix the external power supply of the router to prevent the power cords from falling down
See Figure 1 and Figure 2 for illustrations of this procedure.
Figure 1 The Bottom of the Router
Figure 2 Hanging the Router on a Vertical Surface
| Installing the Router on a Workbench | To install the router on a workbench, take the following precautions:■Make sure that the workbench is smooth and stable.■Leave a heat-dissipation clearance of 10cm (4in) around the router.■Do not put heavy things on the router. |
| Connecting the Protection Ground Wire | Properly connect the protection ground (PGND) wire before connecting other cables. Shorten the ground wire as much as possible to avoid the router and the peer device being damaged during lightning.The AC input of the router is connected to an AC noise filter whose neutral point is connected to the chassis directly, that is PGND (protection ground). The chassis must be grounded properly, to improve the router's ability to resist electromagnetic interference. The PGND also provides protection for the external network, to ensure that the PGND wire lets out the lightning current.The grounding point of the chassis is located on the rear panel and is labeled with a grounding label. The grounding resistance should not be greater than 5 ohm. Connect this point to the ground using a grounding wire. |
| Connecting the Power Cable | External AC power supplies are provided for Router 3000 series routers. The power supplies have the following specifications:■Input: 100 to 240VAC, 50/60Hz, 0.5 to 1 A■Output: 12VDC, 4AConnect the power supply to a 3-core outlet with a neutral point. The neutral point of the outlet should be grounded reliably.To connect the power supply:1 Turn off the power to the router.2 Connect the output end of the power supply to the power socket on the rear panel of the router.3 Connect the input end of the power supply to the AC power outlet.4 Turn on the power switch on the router.5 Confirm that the router has power by checking whether the POWER LED is on. |
Figure 3 illustrates the power supply.
Figure 3 Router 3000 Power Supply

2 Connect the output of the power supply to the power input on the rear panel of the router.
3 Insert the input connector of the power supply into an AC power outlet.
4 Turn on the power the power to the router.
5 Confirm that the router has power by checking whether the POWER LED is on.
6 If you repeat this procedure several times and the POWER LED remains off, see Chapter 6, Troubleshooting.
Connecting the Router to the Console Terminal
The Router 3000 series routers provide an EIA/TIA-232 asynchronous serial console port, through which you can configure the router.
The console cable is an 8-core shielded cable. The end that is used to connect to the console port of the router has an RJ-45 connector. The other end of the console cable has both a DB-9 (female) adapter and a DB-25 (female) adapter. Use the appropriate connector for the port on the console terminal.
Figure 4 illustrates the console cable.
Figure 4 Console Cable Assembly
See Appendix A for the pinout details of the console cable.
To configure the router through the console terminal:
1 Turn off power to the router.
2 Select a console terminal — The console port can be either a standard ASCII terminal with an RS-232 serial interface, or a PC.
3 Connect the cable — Turn the power switch off, and then connect the RS-232 serial interface of the console cable to the console port of the router.
After the connection and verification, power on the router. The startup information of the router is displayed on the console terminal.
Connecting the Router to the Ethernet
The Router 3000 series routers provide a fixed 10/100BASE-TX fast Ethernet interface that uses category-5 twisted pair cable, as shown in Figure 5
Figure 5 Ethernet Cable Assembly
The Ethernet cables are classified as straight-through network cable and crossover network cable. They have the following features:
■Straight-through network cable — The sequences of the wires crimped at the RJ-45 connectors of the two ends are the same. The cable is used in the connection between a terminal device, such as a PC or a router, and the Hub or LAN Switch. Straight-through network cables are delivered along with the router.
■Crossover network cable — The sequences of the wires crimped at the RJ-45 connectors of the two ends are different. The cable is used in the connection between the terminal device, such as a PC or a router, and another terminal device. You can create this cable yourself, if necessary.
For the pinouts, identification and making of the two network cables, see Appendix A. Take the following considerations into account before you connect:
■The fixed Ethernet cables are included in the standard configuration of the router.
■ Use shielded cables to ensure electromagnetic compatibility.
■Identify the mark on the module port so you can plug the cable in correctly.
■ When connecting the Ethernet cable to a LAN Switch, plug the cable into the 10/100BASE-T interface marked with MDIX.
To connect the Ethernet cable:
1 Turn off power to the router.
2 Select the Ethernet cable.
When connecting the router with a PC or a router, use the crossover network cable.
When connecting the router to a hub or a LAN switch, use the straight-through network cable.
3 Connect one end of the Ethernet cable to the appropriate Ethernet module on the router.
4 Connect the other end of the Ethernet cable to the Ethernet interface of the Hub or the LAN switch.
5 Verify the connection by checking that the 100M ETH LED on the top of the router is on.
Connecting the Router to the WAN
The Router 3000 series routers provide the following WAN interfaces:
■AUX port (all models)
■ Mutiprotocol synchronous/asynchronous serial port (Router 3012, Router 3013, Router 3015)
■ISDN S/T (Router 3013)
■ISDN U (Router 3015)
■CT1/PRI (Router 3016)
Connecting the AUX Port to the Modem
The auxiliary (AUX) port is an EIA/TIA-232-compliant sync/async serial interface that is used for remote configuration or dial-up backup. To be connected to a remote device, a local modem must be connected to a remote modem through PSTN. For the connection method, see Chapter 4, Booting and Configuring the Router. If the console port fails, the AUX port can also serve as a console port. For AUX port specifications, see Chapter 1, Overview.
The AUX cable is an 8-core shielded cable. One end of the cable has an RJ-45 connector and connects to the AUX port of the router. The other end has both a DB-25 (male) adapter and a DB-9 (male) adapter. Use the appropriate connector for the port on the modem.
Figure 6 illustrates the AUX cable.
Figure 6 AUX Cable Assembly
To connect the AUX cable:
1 Turn off power to the router.
2 Plug the RJ-45 connector of the AUX cable into the AUX port of the router.
3 Connect the DB-25 or DB-9 adapter of the AUX cable to the serial interface of the analog modem.
For pinout details of the AUX cable, see Appendix A.
Connecting the Synchronous/Asynchronous Serial Interface to a CSU/DSU
The synchronous/asynchronous serial interface is usually used to connect a WAN device, such as a modem, and a CSU/DSU. It can operate in synchronous/asynchronous mode and DTE/DCE mode. For the attributes of the interface, see Chapter 1, Overview.
Synchronous and Asynchronous mode
V.35 and V.24 (EIA/TIA-232) standards support synchronous operating mode, while only V.24 (EIA/TIA-232) standard supports the asynchronous operating mode. The maximum transmission distance and baud rate of the signal vary with the operating mode. See Table 1 for the details.
Table 1 Transmission Rate and Transmission Distance of V.24 (EIA/TIA-232)/V.35 Cable
| V.24 (EIA/TIA-232) V.35 | |||
| Baud Rate (bps) | Maximum Transmission Distance (m) Baud Rate (bps) | Maximum Transmission Distance (m) | |
| 2400 60 2400 1250 | |||
| 4800 60 4800 625 | |||
| 9600 30 9600 312 | |||
| 19200 30 19200 156 | |||
| 38400 20 38400 78 | |||
| 64000 20 56000 60 | |||
| 115200 10 64000 50 | |||
| -- 2048000 30 | |||
Caution: The baud rate should not exceed 64 Kbps when the V.24 cable operates in synchronous mode.
DTE and DCE mode
The synchronous serial interface can operate in both DTE mode and DCE mode. For two devices connected directly, one device should operate in DTE mode, and the other device should operate in DCE mode. The DCE mode device provides a synchronous clock and specifies the transmission rate, the DTE mode device accepts the synchronous clock and communicates at the specified transmission rate. Usually, the router serves as the DTE device. To determine whether the device is a DTE or a DCE, refer to the user manual for the device. Table 2 helps identify DTE and DCE devices.
Table 2 Typical DTE and DCE
| Type of Equipment | Type of Interface | Typical Equipment |
| DTE male PC or router | |
| DCE female Modem, multiplexer or CSU/DSU |
In general, the asynchronous serial interface is connected to a modem or a terminal adapter (TA) to act as the dial-up interface. In this case, it is unnecessary to determine whether the device is DTE or DCE, you must only select the appropriate baud rate.
The synchronous/asynchronous serial interface cable is connected to a DB-50 receptacle. Proper connection cable needs to be selected for the protocol applied.
Nine types of synchronous/asynchronous serial interface cables are available. However, these cables are optional and you must select the proper one based on your requirements when you purchase the router All these types of cables have a DB-50 adapter at the router end.
At the network end, the connector is different for each type of cable, as described in the following list:
■V.24 (EIA/TIA-232) DTE cable — DB-25 (male) adapter
■ V.24 (EIA/TIA-232) DCE cable — DB-25 (female) adapter
■V.35 DTE cable — 34-pin (male) adapter
■V.35 DCE cable — 34-pin (female) adapter
■X.21 DTE cable — DB15 (male) adapter
■X.21 DCE cable — DB15 (female) adapter
■EIA/TIA-449 DTE cable — DB37 (male) adapter
■EIA/TIA-449 DCE cable — DB37 (female) adapter
■EIA-530 DTE cable — DB25 (male) adapter
For the pinouts of these cables, see Appendix A.

Use the following procedure to connect the synchronous/asynchronous cable to the SERIAL0 interface and the DSU/CSU device:
1 Turn off power to the router.
Caution: Plugging/unplugging the connectors of the synchronous/asynchronous serial interface online can damage the router or the remote device.
2 Choose the appropriate synchronous/asynchronous cable.
3 Plug the DB-50 adapter of the cable into the SERIAL0 interface of the router.
4 Connect the other end of the cable to the CSU/DSU device. (If the WAN uses a dial-up line, connect the cable to the serial interface of the analog modem. See Connecting the AUX Port to the Modem.)
Connecting to the CT1/PRI Port
The Router 3016 provides a CT1/PRI port that provides CT1 (channelized T1) access and implements the ISDN PRI function. See CT1/PRI interface attributes.
CT1/PRI cable is a 100 ohm shielded straight-through cable and both ends of which are RJ45 connectors, as shown in Figure 16.
Figure 16 T1 Cable
For pinout details of the T1 cable, see Appendix A.
To connect the T1 cable:
1 Turn off power to the router.
Caution: Identify the mark on the CT1/PRI port. Plugging the connector in incorrectly can cause damage to the router.
2 Insert the connector at one end of the T1 cable into the CT1/PRI port of the router.
3 Insert the connector at the other end of the T1 cable into the corresponding device.
4 Power on the router and verify that T1-LNK LED on the top of the router chassis is lit. If it is off, check the connection cable.
Connecting to the ISDN Port
The Router 3013 router provides an ISDN S/T port, and the Router 3015 router provides an ISDN U port. These routers perform data transfer in 2B+D mode and support both ISDN dial-up and leased line. See for the ISDN interface attributes.
ISDN S/T Cable
The ISDN S/T cable for the Router 3013, shown in Figure 17, is a 4-core twisted pair cable. Both ends of the cable have RJ-45 connectors, of which, 3-pin and 6-pin are sending end, and 4-pin and 5-pin are receiving end.
Figure 17 ISDN S/T Cable

Press Enter. The system displays the [3Com] prompt, which indicates that the router has entered the system view and you can configure the router.
Configuration Fundamentals of the Router
The configuration process includes the following steps:
1 Clarify your networking requirements. These requirements include:
■The connectivity requirements of the remote sites
■The types of LAN and WAN interfaces required for the network
■The configuration of IP and IP subnet settings and any other protocols
■ The network reliability, management, and security policies
2 Based on your network requirements, draw a clear and integrated networking diagram.
3 Configure the WAN interface of the router:
- Configure the physical operating parameters (the operating mode of the serial interface, baud rate, and synchronous clock) of the interface according to the transmission medium of the WAN. For the dial-up interface, you need to configure DDR parameters.
- Configure the link layer protocol encapsulated on the interface and the related operating parameters according to the type of the WAN.
4 Configure the IP addresses or IPX network number for all the ports of the router according to the division of the subnets.
5 Configure the routes. If you have to start up the dynamic routing protocol, configure the related operating parameters of the protocol.
6 Create the security configuration for the router, as necessary.
7 Create the reliability configuration for the router, as necessary.
SNMP Management
For help managing routers on your network, you can use 3Com Network Supervisor software to discover, map, and display network links and IP devices.
To allow Network Supervisor to monitor your routers, you must first configure SNMP V1 and SNMP Trap support with the following commands:
[3Com] snmp-agent sys-info version v1
[3Com] snmp-agent community read <read-community-string>
[3Com] snmp-agent community write <write-community-string>
[3Com] snmp-agent trap enable
[3Com] snmp-agent target-host trap address <addr> parameter v1 securityname <security-name-string>
In this example,

Command Line Interface
The command line interface of the Router 3000 series routers provides commands to configure and manage the router. The command line interface has the following characteristics:
■Performs the local configuration through the console port.
■ Performs local or remote configuration through the telnet command, which can be used to log on directly and manage other routers.
■Implements the configuration on the router through the terminals (the asynchronous interface, including those connected to the AUX port and AS port) in the dumb terminal mode.
■Configures the hierarchical user protection (guest, operator, administrator). Only administrator users are authorized to configure and manage the routers.
■Online help, available by typing? at any time.
■ Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose the availability of the network.
■Provides detailed debugging information to diagnose network faults.
■The command line interpreter adopts fuzzy search for the keywords of the command. A conflict-free keyword if entered, will be interpreted accordingly. For example, for a display command, you can enter dis.
To facilitate the management of the router in the system view, all the commands are grouped. Each group corresponds to a view. Users can use these commands to switch between different views. Many commands are limited to use in a single view. Other commands (such as ping, display current-configuration, interface) can be executed in all views.

Uploading and Downloading Applications and Configuration Files Using FTP
Uploading files involves transferring them from a PC running the FTP client to a router running the FTP server, through the router's Ethernet interface. This is called a put operation.
Downloading files involves transferring them from the FTP server on the router, through its Ethernet port, to the PC running the FTP client. This is called a get operation. All FTP clients, including local and remote users, who are connected to a router can upload and download if they pass user authentication.
To transfer files using FTP, you must create the appropriate configuration, as shown in Figure 5 and Figure 6, and described in the following procedures.

To create a remote FTP upload/download configuration:
1 Connect the PC to any port on the router through a WAN. This procedure does not require that the IP address of the PC and that of the router be on the same segment and is used for remote upgrading routers.
2 Copy the application program files or configuration files to a path, the default is C:\version.
To start the FTP server on the router and to set the user name and password, you should work with the maintenance personnel at the router site. All FTP client programs can use the username and password to log on to the FTP server.
To start the FTP server and set the user name and password:
1 Set the authentication mode:
2 [3Com] aaa-enable
3 [3Com] aaa authentication-scheme login default local
4 [3Com] aaa accounting-scheme optional
5 Add the user name and password:
[3Com] local-user user password simple 123 service-type ftp where user is the user name and 123 is the password.
6 Start the FTP server:
[3Com] ftp-server enable
To upload or download an application program file or configuration file:
1 In DOS mode, enter the path where the application or configuration files are located.
2 Execute the FTP command and set up the FTP connection with the router. For example:
C:\version\ftp 10.110.10.10
If the connection is set up, the following information displays:
Connected to 10.110.10.10 220 FTP server ready on R3000 at User(10.110.10.10:(none)):
3 Use the username and password that have already been set on the router to log on to the FTP server.
User(10.110.10.10:(none)): user 331 Password required for ftp Password: 230 User ftp logged in ftp>
The appearance of the ftp> prompt indicates that you can begin the upload or download operation.
During the upload and download operation, the default name of the router's application program is SYSTEM. Configurations file are named CONFIG by default.
4 To upload the application or configuration files, enter the appropriate path and file name at the following prompts:
ftp>put
local file
remote file
After the uploading is completed, the ftp> DOS prompt displays again.
5 Enter dir to display the name and size of the file on the router. If the upload is successful, the sizes of the file on the router and on the PC will be the same.
6 To download the application or configuration files, enter the appropriate path and file name at the following prompts:
ftp>get
local file
remote file
After the upload or download is complete, exit the FTP client program:
ftp>quit

[R3000] save
6 Execute the save command after modifying the user password to save the change.
If the Boot ROM password for the router is lost, contact your Service representative.
Maintaining Router Hardware
In preparation for the maintenance of your router hardware, collect and have ready the following tools:
■Phillips screwdriver
■ESD-preventive wrist strap and ESD-preventive glove
■Static shielding bag
■Chip extractor
Caution: Observe the following precautions when maintaining your router hardware:
■There is a seal on one of the screws on the chassis of the Router 3000 routers. When the Service representative performs maintenance on the router, the seal is must be intact. Contact your Service representative before you open the chassis.
- Replace the hardware of router sensibly and in a proper way under the guidance of the technical support personnel.
■Confirm that all power supplies have been disconnected from the router while performing the hardware maintenance. Otherwise, the operator may get injured through an electric shock.
■ Wear an ESD-preventive wrist strap and ESD-preventive gloves during the hardware maintenance for the router and ensure that the strap makes a good skin contact.
■For the device to operate normally, use only the SDRAM provided by 3Com Corporation.
Opening the Cover of Router Chassis

When a Boot ROM is damaged or when data that becomes corrupted because of a software failure and cannot be corrected, it should be replaced.
Router 3000 Boot ROMs are located at the same position on the mainboard, as shown in.
Figure 8 Boot ROM Location
Caution: Use a chip extractor to replace the Boot ROM.
To replace the Boot ROM:
1 Insert the top end of the chip extractor into the Boot ROM socket, turn inward slightly, withdraw the extractor upward and lift the Boot ROM out.
2 Put the Boot ROM into the static shielding bag.
3 Insert the end of the chip extractor into the socket of the new Boot ROM.
4 Position the Boot ROM so that the beveled edge of the socket matches the beveled edge on the Boot ROM and plug it into the Boot ROM socket.
Caution: Be careful not to damage or bend the pins at the bottom of the Boot ROM. If the pins are bent, straighten them with needle-nose pliers.
Closing the Router Chassis Cover
To prevent cables from being pressed or cut off when you close the cover of the router chassis, roll up all the cables and put them into the chassis before closing the cover.

TROUBLESHOOTING
The Power LED is Off. If the power LED is off, verify that:
■The power switch of the router is turned on.
■The power supply switch is turned on.
■The power cord of the router is connected properly.
■The power supply suits the requirement of the router.
Caution: Do not plug in or unplug the power cord when the power is on. After having checked the conditions in the previous list, if the power LED is still off, contact your Service representative.
Nothing is Displayed on the Terminal after Power-On
After the system runs the power-on self-test (POST), if the system operates normally, the start-up information is displayed on the console terminal. If the configuration system has a fault, the terminal may display nothing.
If the terminal does not display any information after the power-on self-test, verify that:
■The power system is normal.
■The console cable is connected correctly.
If the power system is normal and the console cable is connected properly, there may be something wrong with the console cable or the HyperTerminal parameters. Check the cable or the parameters.
HyperTerminal parameters should have the following values:
■Baud — 9600
■Data bits — 8
■Stop bit — 1
■Parity — None
■Flow control — None
■Terminal emulation — VT100
If the parameter settings do not match these values, reconfigure them.
If the previous checks do not solve the problem, contact your Service representative and follow the representative's instructions.
Illegible Characters Display on the Terminal after Power-On
If the system operates normally after the system runs the power-on self-test (POST), the start-up information is displayed on the console terminal. If the configuration system has a fault, the terminal may display only illegible characters.
If the console terminal displays illegible characters after the POST, verify that the HyperTerminal parameters are set properly, as follows:
■Baud: 9600
■Data bits: 8
■Stop bit: 1
■Parity: None
■Flow control: None
■Terminal emulation: VT100
If the parameter settings do not match these values, reconfigure them.
