Overview of the Cisco 2518
The Cisco 2518 combines Ethernet hub and router capabilities with a built-in Integrated
Services Digital Network (ISDN) Basic Rate Interface (BRI).
The Cisco 2518 is an intelligent workgroup Ethernet hub with sophisticated internetwork
connectivity provided by its built-in WAN interfaces and the Cisco Internetwork Operating
System (Cisco IOS software).
This hub provides the capabilities of an Ethernet unshielded twisted pair (UTP)
concentrator, an intelligent Simple Network Management Protocol (SNMP) internetwork
router, and an ISDN terminal adapter.
The Cisco 2518 has the following features:
•
•
23 available Ethernet hub ports.
•
•
•
•
•
•
SNMP-managed hub and router ports.
Hub ports and router interfaces that can be configured using a modem, local terminal,
or a PC.
One ISDN (two B channels, one D channel) BRI operating at 128 kbps.
Two synchronous serial interfaces operating at up to 2 Mbps.
One AUI port for an external hub connection.
Numerous Cisco IOS feature sets.
One asynchronous serial interface for low-speed WAN access for dial-on-demand
routing or dial backup connections. Dial-on-demand routing reduces the cost of
wide-area access by making use of ISDN or serial dial-up lines as an alternative to costly
leased lines.
Overview of the Cisco 2518 1-1
•
Easy access to configuration switches and jumpers on the hub port card, management
card, and router card.

Hub Port Cards
Warning The ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Users should not attempt to tamper with or open any public
telephone operator (PTO)–provided equipment or connection hardware. Any hardwired
connection (other than by nonremovable, connect-one-time-only lug) must be made only
by PTO staff or suitably trained engineers. Translated versions of this warning are in the
appendix “Translated Safety Warnings.”
Warning The ports labeled “Ethernet” 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. Translated versions of this warning are in the
appendix “Translated Safety Warnings.”
Hub Port Cards
The hub port card is a slide-in card with 24 Ethernet hub ports.

Preparing for Installation 2-1
Safety Recommendations
•
Do not wear loose clothing that could get caught in the router/hub. Fasten your tie or
scarf and roll up your sleeves.
•
Wear safety glasses if you are working under any conditions that might be hazardous to
your eyes.
•
Do not perform any action that creates a potential hazard to people or makes the
equipment unsafe.
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity.
Warning Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when connected to
power and ground and can cause serious burns or can weld the metal object to the terminals.
To see this warning in multiple languages, see the appendix “Translated Safety Warnings.”
•

if an electrical accident occurs, you can quickly turn off the power.
•
Before working on the system, turn off the power and unplug the power cord.
Warning Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units. To see this
warning in multiple languages, see the appendix “Translated Safety Warnings.”
•
Disconnect all power before doing the following:
— Installing or removing a router/hub
— Working near power supplies
— Performing a software upgrade
•
Do not work alone if potentially hazardous conditions exist.
2-2 Cisco 2518 Router/Hub User Guide
Safety Recommendations
Warning Do not work on the system or connect or disconnect cables during periods of
lightning activity. To see this warning in multiple languages, see the appendix “Translated
Safety Warnings.”
•
Never assume that power is disconnected from a circuit. Always check.
Warning Do not touch the power supply when the power cord is connected. For systems
with a power switch, line voltages are present within the power supply even when the power
switch is off and the power cord is connected. For systems without a power switch, line
voltages are present within the power supply when the power cord is connected. To see this
warning in multiple languages, see the appendix “Translated Safety Warnings.”
•
Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, and missing safety grounds.
•
If an electrical accident occurs, proceed as follows:
— Use caution; do not become a victim yourself.
— Turn off power to the system.
— If possible, send another person to get medical aid. Otherwise, assess the condition
of the victim and then call for help.
— Determine if the person needs rescue breathing or external cardiac compressions;
then take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
Ensure that the router/hub is electrically connected to earth ground. Wear an
ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to
ground. To properly guard against ESD damage and shocks, the wrist strap and cord must
operate effectively. If no wrist strap is available, ground yourself by touching the metal part
of the router/hub.
Preparing for Installation 2-3
General Site Requirements
Caution For safety, periodically check the resistance value of the antistatic strap, which
should be between 1 and 10 megohms.
General Site Requirements
This section describes the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning
installation.
The Cisco 2518 is designed to be rack-mounted in a wiring closet, or placed on a desktop.
Warning Ultimate disposal of this product should be handled according to all national
laws and regulations. To see this warning in multiple languages, see the appendix
“Translated Safety Warnings.”
Site Environment
The location of the individual router/hub and the layout of your equipment rack or wiring
room are extremely important for proper system operation. Equipment placed too close
together, inadequate ventilation, and inaccessible panels can cause system malfunctions
and shutdowns, and can make system maintenance difficult.
When planning your site layout and equipment locations, use the precautions in the
following sections to help avoid equipment failures and reduce the possibility of
environmentally caused shutdowns. If you are currently experiencing shutdowns or
unusually high errors with your existing equipment, these precautions can help you isolate
the cause of failures and prevent future problems.
Preventive Site Configuration
The following precautions will help you plan an acceptable operating environment for the
Cisco 2518 and will help you avoid environmentally caused equipment failures:
•
Remember that electrical equipment generates heat. Ambient air temperature might not
be adequate to cool equipment to acceptable operating temperatures without adequate
circulation. Ensure that the room in which you operate your system has adequate air
circulation.
2-4 Cisco 2518 Router/Hub User Guide
General Site Requirements
•
Always follow the ESD-prevention procedures in the section “Preventing Electrostatic
Discharge Damage” earlier in this chapter to avoid damage to equipment. Damage from
static discharge can cause immediate or intermittent equipment failure.
Configuring Equipment Racks
The following tips will help you plan an acceptable equipment rack configuration:
•
Enclosed racks must have adequate ventilation. Ensure that the rack is not overly
congested because each unit generates heat. An enclosed rack should have louvered
sides and a fan to provide cooling air.
•
When mounting a router/hub in an open rack, ensure that the rack frame does not block
the intake or the exhaust ports. If the router/hub is installed on slides, check the position
of the router/hub when it is seated all the way into the rack.
•
In an enclosed rack with a ventilation fan in the top, excessive heat generated by
equipment near the bottom of the rack can be drawn upward and into the intake ports of
the equipment above it in the rack.
•
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling
air through the router/hub. The best placement of the baffles depends on the airflow
patterns in the rack, which you can find by trying different arrangements.
•
When equipment installed in a rack fails, turn off other equipment in the rack (and in
adjacent racks) to allow the unit under test a maximum of cooling air and clean power.
Power Supply Considerations
Check the power at your site to ensure that you are receiving “clean” power (free of spikes
and noise). Install a power conditioner if necessary.
Warning To avoid injury, read the installation instructions before you connect the system
to its power source. To see this warning in multiple languages, see the appendix “Translated
Safety Warnings.”
Caution To avoid damage from lightning and power surges, install proper grounding.
Preparing for Installation 2-5
General Site Requirements
Caution Some versions of the Cisco 2518 do not have auto-switching power supplies.
Before applying power to the router/hub, make sure the input voltage selection switch on
the power supply is set to the correct voltage for your area. See Figure 2-1.
Warning A voltage mismatch can cause equipment damage and may pose a fire hazard. If
the voltage indicated on the label is different from the power outlet voltage, do not connect
the chassis to that receptacle. To see this warning in multiple languages, see the appendix
“Translated Safety Warnings.”

Creating a Site Log
Creating a Site Log
The site log provides a historical record of all actions relevant to the Cisco 2518. Keep the
site log in an easily accessible place near the router/hub where anyone who performs tasks
has access to it. Use the installation checklist to verify steps in the installation and
maintenance of your system. Site log entries might include the following:
•
Installation progress
Make a copy of the installation checklist and insert it into the site log. Make entries on
the checklist as you complete each procedure.
•
Upgrades and maintenance procedures
Use the site log as a record of ongoing system maintenance and expansion history. Each
time a procedure is performed on the system, update the site log to reflect the following:
— Configuration changes
— Maintenance schedules and requirements
— Corrective maintenance procedures performed
— Intermittent problems
— Related comments and notes
Distance Limitations
When setting up your Cisco 2518, consider distance limitations and potential
electromagnetic interference (EMI) as defined by the Electronic Industries Association
(EIA). Following are the distance limitation specifications for serial interfaces.
Ethernet Connections
The IEEE 802.3 specification for the maximum length of an Ethernet unshielded twisted
pair (UTP) segment is 328 feet (100 meters) at a transmission rate of 10 Mbps.
2-8 Cisco 2518 Router/Hub User Guide
Distance Limitations
Serial Connections
As with all signaling systems, EIA/TIA-232 signals can travel a limited distance at any
given bit rate; generally, the slower the data rate, the greater the distance. Table 2-1 shows
the standard relationship between baud rate and maximum distance.

Caution EIA/TIA-232 is often used at greater distances than those specified in Table 2-1.
If you understand the electrical problems that can arise and can compensate for them, you
might still be able to get good results; however, do so at your own risk. We recommend that
you stay within the distances defined by the standard.
The use of balanced drivers allows EIA/TIA-449 signals to travel greater distances than the
EIA/TIA-232 standard. Table 2-2 lists the standard relationship between baud rate and
maximum distance for EIA/TIA-449 signals. These limits are also valid for V.35 and X.21.

The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps.
Exceeding this maximum could result in loss of data and is not recommended; do so at your
own risk.
Caution
Interference Considerations
When you run cables for any significant distance in an electromagnetic field, interference
can occur between the field and the signals on the cables. This fact has two implications for
the construction of terminal plant cabling:
•
•
Plant cabling can emit radio interference if it is unshielded for too long a distance.
Strong EMI, especially that caused by lightning or radio transmitters, can destroy the
EIA/TIA-232 drivers and receivers in the Cisco 2518.
If you use twisted-pair cables with a good distribution of grounding conductors in your
plant cabling, emitted radio interference is not likely. If you exceed the maximum distances,
ground the conductor for each data signal; however, this practice is not recommended.
If you have cables exceeding recommended distances, or if you have cables that pass
between buildings, give special consideration to the effect of lightning strikes or ground
loops. The electromagnetic pulse caused by lightning or other high-energy phenomena can
2-10 Cisco 2518 Router/Hub User Guide
Console and Auxiliary Port Considerations
easily couple enough energy into unshielded conductors to destroy electronic devices. If
your site has experienced this type of problem, consult experts in lightning suppression and
shielding.
To prevent EMI, consult experts in radio-frequency interference (RFI).
In order to avoid possible EMI interference, follow these recommendations:
•
•
Use category 3 UTP cables for the Ethernet hub ports.
Run the AC power cord away from the Ethernet cables to minimize noise coupling.
Console and Auxiliary Port Considerations
Before connecting the management card console and router card auxiliary ports, read the
following sections.
Management Card Console Port Connection
The management card has an RJ-45 console asynchronous serial port. This port connects
to a terminal or PC with a special blue colored RJ-45 to DB-25 console cable, which is
supplied. The default parameters for the console port are 9600 baud, 8 data bits, no parity
generated or checked, and 1 stop bit. The console port does not support hardware flow
control.
Note You cannot use this console cable for Ethernet or router auxiliary port connections.
Router Card Auxiliary Port Connections
The router card has an RJ-45 asynchronous (AUX) serial port that is used as an auxiliary
port. This port connects to a terminal using an RJ-45-to-DB-25 adapter. Depending on the
adapter used, this port becomes a data communications equipment (DCE) device or a data
terminal equipment (DTE) device. To use the terminal as a console, you should use a DCE
RJ-45-to-DB-25 adapter. The default parameters for the port are 9600 baud, 8 data bits, no
parity generated or checked, and 2 stop bits.
Preparing for Installation 2-11
Network Connection Considerations
Network Connection Considerations
This section contains information about connecting the Ethernet, serial, and BRI ports to
your network.
RJ-45 Ethernet
The Ethernet hub ports are located on the Cisco 2518 router/hub port card, and on the router
card. Use a modular, RJ-45, UTP cable to connect the Ethernet ports to workstations, PCs,
servers, or a media attachment unit (MAU). To connect to another hub, use a cross-connect
UTP cable.
Serial
Two serial interface ports are located on the router card. The serial ports use 60-pin, D-type
connectors. All serial interfaces except the EIA-530 interface can be configured as DCE
using a DCE cable. The DTE serial port needs external clocking, which is provided by a
channel service unit/data service unit (CSU/DSU) or modem.
You must use a special serial cable to connect the router card to a modem or CSU/DSU.
This cable is available from Cisco Systems and can be ordered with the system. The cable
uses a DB-60 connector on the router/hub end. For cable specifications, see the appendix
“Cabling Specifications.” For ordering information, contact a customer service
representative.
BRI
The Basic Rate Interface (BRI) port is an RJ-45 8-pin jack located to the right of the serial
port on the daughter card. Use an appropriate cable to connect the system directly to the
ISDN through the NT1. The common carrier will provide the NT1 connection worldwide,
except in North America, where the NT1 is owned by individual customers.
Warning Before opening the chassis, disconnect the telephone-network cables to avoid
contact with telephone-network voltages. To see this warning in multiple languages, see the
appendix “Translated Safety Warnings.”

Configuring the router card using AutoInstall
You should follow the procedure that best fits the needs of your network configuration.
Note When you finish configuring the router card, enter Ctrl-Q to return to the console
prompt.
4-2 Cisco 2518 Router/Hub User Guide
Configuring the Router Card
Configuring the Router Card Manually
If you do not plan to use AutoInstall, do not connect the router card’s serial (WAN) cable
to the CSU/DSU or the router card itself. This will prevent the router card from attempting
to run the AutoInstall process. The router card will attempt to run AutoInstall whenever you
start it if the serial (WAN) connection is connected on both ends and the router card does
not have a configuration stored in NVRAM.
It can take several minutes for your router card to determine that AutoInstall is not set up
on a remote TCP/IP host. After the router card determines that AutoInstall is not
configured, it will default to the setup routine. If the serial (WAN) cable is not connected,
the router card will boot from Flash memory and go into the setup routine.
Note You can run the setup routine any time you are at the enable prompt (#) by entering
the setup command.
When you have booted from Flash memory, the following information appears after about
30 seconds.
Step 1 If you are not connected to the router card, use the router command from the

#######
The router is now configured.
Configuring the Router Card Using AutoInstall
The AutoInstall process is designed to configure the router card automatically after
connecting to your wide-area network (WAN). For AutoInstall to work properly, a
Transmission Control Protocol/Internet Protocol (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 if the following two conditions are maintained:
1 The host must be on the opposite side of the router card’s serial connection to the WAN.
2 User Datagram Protocol (UDP) broadcasts to and from the router card and the TCP/IP
host must be enabled.
This functionality is coordinated by your system administrator at the site where the TCP/IP
host is located. Do not attempt to use AutoInstall unless the required files have been
provided on the TCP/IP host.
To prepare your router card for the AutoInstall process:
Step 1 Shut down the Cisco 2518.
Step 2 Place the Cisco 2518 in a location that will allow the serial (WAN) cable to make
a connection between the router card and the CSU/DSU without placing a strain
on the cable.
Step 3 Attach the serial cable or cables to the Cisco 2518 and the CSU/DSU.
Configuring the Router Card 4-9
Configuring the Router Card
Step 4 The BRI port, which is a female RJ-45 connector (see Figure 4-1), is located on
the interface panel of the daughter card above the serial 1 port.
Using the appropriate cable, connect the BRI port to the ISDN through the NT1.
The common carrier will provide the NT1 connection worldwide, except in North
America where the NT1 is owned by individual customers.
The router card will load the operating system image from Flash memory. If the
remote end of the WAN connection is connected and properly configured, the
AutoInstall process will begin.

BRI cable, detach the end away from the router card first to avoid possible electric shock.
Network hazardous voltages also are accessible on the router card in the area of the BRI
port (RJ-45 connector), regardless of when power is turned off. (See Figure 4-2.) To see
translated versions of this warning in multiple languages, see the appendix “Translated
Safety Warnings.”

The router card will send a Serial Line Reverse Address Resolution Protocol (SLARP)
packet over the serial line. When the packet reaches the opposite end of the WAN
connection, the remote router will reply with the IP address of its serial interface. The router
card will increment the serial interface address by one and assign this address to its own
serial interface. This process will take approximately one minute.
Note The remote router’s IP address must have a 1 as the fourth byte—for example,
127.100.21.1.
After the serial interface on the router card has been assigned a valid serial interface IP
address, it will resolve its host name. It will send a Trivial File Transfer Protocol (TFTP)
request on the serial line for the configuration file called network-confg. If the TCP/IP host
responds with this file, AutoInstall will search the file’s contents for the host name
associated with its IP address.
If the TCP/IP host does not respond with the network-confg file, AutoInstall will broadcast
a reverse domain name server (DNS) request containing the IP address for the router card’s
serial port that it was assigned over the network. If the DNS services have been set up,
AutoInstall will resolve the router card’s name from this file. After the IP address and host
Configuring the Router Card 4-11
Configuring the Router Card
name have been found, AutoInstall will broadcast a TFTP request to the TCP/IP host for
the file called hostname-confg. If this file has been set up by the system administrator, it
will be downloaded automatically to the router card’s memory, completing the
configuration.
If the AutoInstall completed successfully, you still need to write the configuration data to
the router card’s nonvolatile random-access memory (NVRAM) and reset the configuration
registers. Perform the following steps to complete these tasks:
Step 1 Enter the enable command to enter enable mode. Configuration changes can only
be made in enable mode.
Hostname> enable
Step 2 Enter the enable password that was configured into the router card by the
AutoInstall process:
Password:*******
Step 3 Enter the following command at the prompt:
c2518(boot)# copy running-config startup-config
This will save the configuration settings that the AutoInstall process created in the
router card. If you fail to do this, your configuration will be lost the next time you
reload the router card.
Step 4 You can check the value of these settings by entering the show version command
at the Hostname# prompt:
Hostname# show version
.
.
.
configuration register is 0x0 (will be 0x2102 at next reload)
If the AutoInstall feature is not set up, or if your router card is unable to locate the
appropriate files, you should use the manual configuration with or without the setup utility.

Network Connectivity
This chapter contains information on using the Cisco 2518 synchronous ports,
asynchronous serial ports, and BRI port.
The ports labeled “ETH,” “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 circuits.
Also, make sure the host chassis is connected to earth ground during normal use.
Synchronous Serial Connections
The Cisco 2518 serial ports provide two dedicated serial port interfaces operating in either
DTE or DCE mode, compatible with leased-line, circuit-switched, and packet-switched
services at speeds up to 2 Mbps. The serial port connectors use flexible serial transition
cables that allow easy transition to any of the common physical interfaces, including V.35,
EIA/TIA-232, EIA/TIA-449, EIA/TIA-530, and X.21.
The synchronous serial ports can be configured to connect SDLC devices to a corporate
internetwork, as shown in Figure 5-1.

CHAPT E R
Configuring the Cisco 2518
SNMP Agent with SPSET
This chapter describes the System Parameter Setup program (SPSET). SPSET resides in
the Cisco router/hub firmware, and is used to configure or modify the Cisco router/hub
simple network management protocol (SNMP) agent.
Note You do not need to run SPSET to configure the SNMP agent. After you have
configured the router card, PCbus ARP automatically assigns the agent’s IP address and
subnet mask.
Use SPSET to perform the following modifications:
•
•
•
•
•
Modify parameters.
Set serial port communication parameters.
Establish SNMP community names.
Set the SNMP managers to receive SNMP trap messages.
Save or delete router/hub management functions in NVRAM.
Configuring the Cisco 2518 SNMP Agent with SPSET 6-1
Running SPSET
Running SPSET
Connect a terminal or PC to the Cisco router/hub console port as described in the chapter
“Installing the Router/Hub.” SPSET is designed to use ANSI screen codes, therefore to see
a proper screen display, you should use a PC or VT100 terminal running ANSI emulation.
When the Cisco router/hub is powered on, the SNMP agent is configured to the values
stored in SPSET. To run the SPSET program, perform the following steps:
Step 1 If the SNMP agent is running, enter Ctrl-E several times until you see the <<C>>
prompt. This will stop the SNMP agent.
Note To restart the SNMP agent, enter AGENT at the <<C>> prompt.
Step 2 Enter SPSET and press Return to display the System Parameters Setup Main
Menu. If you want help messages to display at the bottom of the screen, enter
SPSET -HELP and press Return.

SELV Circuit Warning
Varning! ISDN-anslutningen betraktas som en spänningskälla och bör inte vara åtkomlig
för användaren (ISDN: Integrated Services Digital Network = digitalt flertjänstnät).
Användare får inte manipulera eller söka öppna utrustning eller anslutningsdon som
tillhandahållits av telefonbolag (PTO-produkter). Anslutning av ledningar (med undantag
av icke löstagbara kabelskor för engångsanslutning) får endast utföras av PTO-anställda
eller lämpligt utbildade tekniker.
SELV Circuit Warning
Warning The ports labeled “ETH,” “Token Ring,” 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.
Waarschuwing De poorten die "ETH", "Token Ring" en "AUX" zijn gelabeld, zijn
veiligheidscircuits met extra lage spanning (genaamd SELV = Safety Extra-Low Voltage).
SELV-circuits mogen alleen met andere SELV-circuits verbonden worden. Omdat de
BRI-circuits op dezelfde manier als telefoonnetwerkspanning behandeld worden, mag het
SELV-circuit niet met de telefoonnetwerkspanning (TNV) circuits verbonden worden.
Varoitus Portit, joissa on nimet "ETH", "TokenRing" ja "AUX", ovat erityisen pienen
jännitteen omaavia turvallisuuspiirejä (SELV-piirejä). Tällaiset SELV-piirit tulee yhdistää
ainoastaan muihin SELV-piireihin. Koska perusluokan liitäntöjen (Basic Rate Interface- eli
BRI-liitännät) jännite vastaa puhelinverkoston jännitettä, vältä SELV-piirin yhdistämistä
puhelinverkoston jännitepiireihin (TNV-piireihin).
Attention Les ports étiquetés « ETH », « oken
T Ring » et « A
UX » sont des circuits de
sécurité basse tension (Safety Extra-Low Voltage ou SELV). Comme les circuits BRI sont
considérés comme des sources de tension de réseau téléphonique, éviter de connecter un
circuit SELV à un circuit de tension de réseau téléphonique (telephone network voltage ou
TNV).
Warnung Die mit "ETH", "Token Ring" und "AUX" beschrifteten Buchsen sind
Sicherheitskreise mit Sicherheitskleinspannung (Safety Extra-Low Voltage = SELV).
SELV-Kreise sollten ausschließlich an andere SELV-Kreise angeschlossen werden. Da
BRI-Kreise wie Telefonnetzspannungen behandelt werden, ist der SELV-Kreis nicht an
Telefonnetzspannungskreise (TNV) anzuschließen.

BRI Cable Warning
Avvertenza Le porte contrassegnate da "ETH", "Token Ring" e "AUX" sono circuiti di
sicurezza con tensione molto bassa (SELV). I circuiti SELV devono essere collegati solo ad
altri circuiti SELV. Dato che i circuiti BRI vengono trattati come circuiti a tensione di rete
telefonica, evitare di collegare il circuito SELV ai circuiti in cui è presente la tensione di
rete telefonica (TNV).
Advarsel Utgangene merket "ETH", "Token Ring" og "AUX" er lavspentkretser (SELV)
for ekstra sikkerhet. SELV-kretser skal kun kobles til andre SELV-kretser. Da BRI-kretsene
håndteres som telenettspenning, bør du unngå å koble SELV-kretsen til kretser for
telenettspenning (TNV).
Aviso As portas com as etiquetas "ETH", "Token Ring" e "AUX" são circuitos de
segurança de baixa tensão (SELV). Estes circuitos deverao ser ligados apenas a outros
circuitos SELV. Devido ao facto dos circuitos BRI (Interface de Ritmo Básico) serem
tratados como sendo de tensão equivalente à da rede telefónica, evite ligar o circuito SELV
aos circuitos TNV (tensão de rede telefónica).
¡Advertencia! Los puertos "ETH", "Token Ring", y "AUX" son circuitos de muy baja
señal que garantizan ausencia de peligro (Safety Extra-Low Voltage = SELV). Estos
circuitos SELV deben ser conectados exclusivamente con otros también de tipo SELV.
Puesto que los circuitos tipo BRI se comportan como aquéllos con voltajes de red
telefónica, debe evitarse conectar circuitos SELV con circuitos de voltaje de red telefónica
(TNV).
Varning! De portar som är märkta "ETH", "Token Ring" och "AUX" är SELV-kretsar,
d.v.s. skyddskretsar med extra låg spänning (SELV: Safety Extra-Low Voltage =
skyddsklenspänning). SELV-kretsar får endast anslutas till andra SELV-kretsar. Eftersom
BRI-kretsar behandlas liksom telefonnätsspänning bör SELV-kretsen inte anslutas till
telefonnätsspänningskretsar (TNV-kretsar).
BRI Cable Warning
Warning Hazardous network voltages are present in the BRI cable. If you detach the BRI
cable, detach the end away from the AccessPro card first to avoid possible electric shock.
Network hazardous voltages also are present on the system card in the area of the BRI port
(RJ-45 connector), regardless of when power is turned off.

Troubleshooting Your Router Card
Troubleshooting Your Router Card
Your router card was intensively tested before it was shipped from the factory. Although it
is unlikely that the card will exhibit any problems, if your system appears to have problems
at startup, read the remainder of this appendix to identify the problem.
Problem Solving
To solve problems in the router card, you need to isolate the problem to a specific source,
if possible. By comparing what the router is actually doing to what it should be doing, you
can greatly simplify troubleshooting.
When troubleshooting the router card, consider the subsystems of the card:
•
Power system
This includes the Cisco 2518 power supply and the ISA bus system.
•
Network interfaces
The LEDs related to your network interface (Ethernet interface and serial WAN) are
used to help identify a failure. For information on LED indicators, refer to the following
section, “Reading the LED Indicators.”
•
System cables
This includes all the interface cables that connect the router card to the network.
Reading the LED Indicators
The router card and the daughter card each have two LED indicators on the interface panel.
The upper LED on the main card indicates the activity of the LAN interface on the card.
The lower LED on the main card indicates its functional condition.
The upper LED on the daughter card indicates the activity on serial port 1 on the daughter
card. The lower LED on the daughter card indicates the activity of the WAN (BRI) port.
(See Figure C-8.)

If the interface LED is not on when the interface is active, and the interface is correctly
connected, a problem might be indicated. Contact your system administrator. If an interface
is extremely busy, its LED will be on all the time. The green OK LED (below the interface
LED) will be on after the router card initializes correctly.
C-14 Cisco 2518 Router/Hub User Guide
Recovering a Lost Password
Troubleshooting Network Interfaces and Cables
The cables that connect the router card to your network must be securely fastened to
provide a trouble-free connection. If you suspect a problem with the cables, check the
following conditions and contact your system administrator.
•
A network interface is not recognized by the router card.
— Check the interface cable connection. The Ethernet port on the router card must
connect externally to the router port on the Cisco 2518 hub card.
— Check the LED that corresponds to that interface.
•
A network interface is recognized, but it will not initialize.
— Check the interface cable or the router configuration. Try toggling the interface by
issuing a shutdown command followed by a noshutdown command.
•
The router card will not boot properly, or reboots constantly or intermittently.
— This could be a problem with the processor or the software.
•
The router card boots, but the console screen is frozen.
— Check the console baud rate in your terminal emulator. It should be set to 9600
baud.
•
Your router card powers on and boots with a particular interface disconnected.
— Check the network interface connection.
Recovering a Lost Password
If you lose your enable password, or cannot remember it, you can recover it.
Systems running Cisco IOS Release 10.3(2) software or later use the enable secret
password, which is encrypted, and therefore cannot be recovered. If you lose your enable
secret password, you must configure a new one.
Following is the procedure for recovering a lost enable password and configuring a new
enable secret password. Before beginning this procedure, you should have terminal
emulation software running on your PC.
Router Card Maintenance C-15
Recovering a Lost Password
The password recovery procedure takes place in the following three steps:
1 Connect to the router card and enter ROM monitor mode.
2 Configure a new enable secret password or recover a lost enable password.
3 Save the configuration changes you make to NVRAM.
Entering ROM Monitor Mode
Take the following steps to enter ROM monitor mode:
Step 1 Connect to the router card via telnet or the management card router command.
Step 2 Enter the command show version to display the existing configuration register
value. Note this value for later use in Step 4 in the section “Saving Configuration
Changes.”
Step 3 If Break is disabled on the router card, reboot the card. If Break is enabled, send a
Break and then proceed to Step 4.
Step 4 Within 60 seconds of rebooting the card, press the Break key. This causes the
terminal to display the bootstrap program prompt (>).
Step 5 To reset the configuration register to boot from the boot ROMs and ignore
NVRAM, enter the following command at the bootstrap prompt:
> o/r 0x041
Note A key to recovering a lost password is to set the configuration register so that the
contents of NVRAM are ignored (0x0040), which allows you to see your password.
Step 6 Initialize the router card by entering the following command:
> i
C-16 Cisco 2518 Router/Hub User Guide
Recovering a Lost Password
Step 7 The router card will power cycle, the configuration register will be set to 0x141,
and the router card will boot the boot ROM system image and prompt you with
the system configuration dialog as follows:
--- System Configuration Dialog ---
Enter no in response to the system configuration dialog prompts until the
following system message is displayed:
Press RETURN to get started!
Step 8 Press Return. The boot ROM prompt appears as follows:
Router(boot)>
Step 9 Enter the command enable to enter EXEC mode in the boot ROM image. The
prompt changes to a pound sign (#):
Router(boot)#
If you lost an enable secret password, follow the steps in the following section “Configuring
a New Enable Secret Password.” If you lost an enable password, follow the steps in the
section “Recovering a Lost Enable Password” later in this chapter.
Configuring a New Enable Secret Password
Take the following steps to configure a new enable secret password:
Step 1 Enter the command configure memory to save the stored configuration in
NVRAM:
Router(boot)# conf mem
Step 2 Enter the enable secret command to configure a new enable secret password and
press Ctrl-Z to exit configuration mode:
Router(boot)# enable secret password
Router(boot)# ^Z
After configuring the new enable secret password, save your configuration changes by
following the steps in the section “Saving Configuration Changes” later in this appendix.
Router Card Maintenance C-17
Recovering a Lost Password
Recovering a Lost Enable Password
Take the following steps to recover a lost enable password:
Step 1 If your password is clear text, enter the EXEC command show configuration to
display the enable password in the configuration file and to display any boot
system commands.
Router(boot)# show config
Step 2 Locate the enable password command entry in the configuration and record the
enable password.
After recovering the enable password, save your configuration changes by following the
steps in the next section, “Saving Configuration Changes.”
Saving Configuration Changes
Take the following steps to save the configuration to NVRAM:
Step 1 Enter the command copy running-config startup-config:
Router(boot)# copy running-config startup-config
Caution Entering the command write memory or copy running-config startup-config
at this point will override the configuration. Make certain you have a backup copy of your
configuration file.
Step 2 Enter the command configure terminal at the EXEC prompt. You are prompted
as follows:
Router(boot)# conf term
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
Step 3 Enter no in response to any boot system command in the configuration file.
Step 4 Enter the command config-register 0xvalue to change the configuration register
value back to its original value (noted from Step 2 in the section “Entering ROM
Monitor Mode”). The factory default is 0x2102.
config-register 0x2102
