THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Preface

Opening a TAC Case

Using the online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer.

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers: Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

EMEA: +32 2 704 55 55 USA: 1 800 553-2447

Obtaining Technical Assistance

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions. Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You

and Cisco will commit all necessary resources around the clock to resolve the situation. Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your

business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Memory Types

Chapter 1 Overview of Cisco 3600 Series Routers

This section describes the various types of memory that may be present in a Cisco 3600 series router.

Cisco 3600 series routers support the following types of memory:

• DRAM or SDRAM—Stores the running configuration and routing tables, and is used for packet

buffering by the router’s network interfaces. The Cisco IOS software executes from DRAM.

• Nonvolatile random-access memory (NVRAM)—Stores the system configuration file and the

virtual configuration register. (For more information, see Appendix C, “Configuration Register.”)

• Flash memory—Stores the operating system software image. You can also add Flash memory on

PCMCIA cards and compact Flash cards, depending on the router.

• EPROM-based memory—Stores the ROM monitor, which allows you to boot an operating system

software image from Flash memory or PCMCIA memory.

Interface Numbering

Cisco 3620 and Cisco 3640 Interfaces

Each individual network interface on a Cisco 3620 or Cisco 3640 router is identified by a slot number and a unit number.

Slot Numbering

The Cisco 3620 or Cisco 3640 router chassis contains two or four slots in which you can install modules. You can install any module into any available slot in the chassis. For Cisco 3620 and Cisco 3640 routers, the slots are numbered as follows:

• Slot 0 is at the bottom right (as viewed from the rear of the chassis), near the power supply.

• Slot 1 is at the bottom left.

• Slot 2 is at the top right, above slot 0.

Chapter 1 Overview of Cisco 3600 Series Routers

• Slot 3 is at the top left, above slot 1.

Unit Numbering

Cisco 3600 series routers have unit numbers that identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the unit number; for example, Ethernet 0/0.

Figure 1-7 shows a router with a 2E 2-slot module in slots 0 and 1. Two serial WAN interface cards are

installed in the module in slot 0. One serial and one ISDN BRI WAN interface card are installed in the module in slot 1.

Voice Interface Numbering

Voice interfaces are numbered as follows: interface-type chassis-slot/voice-module-slot/voice-interface For example, Slot 1, voice network module slot 0, is referred to as voice 1/0/0 (closest to chassis slot 0).

Cisco 3631 Interfaces

Each individual interface (port) on a Cisco 3631 router is identified by number as described in the following sections.

WAN and LAN Interface Numbering

The Cisco 3631 router chassis contains the following WAN and LAN interface types:

• One built-in FastEthernet LAN interface

• Two slots in which you can install WAN interface cards (WICs)

• Two single-width slots (slot 1 and slot 2) in which you can install single-width network modules

Interface Numbering

The numbering format is Interface-type Slot-number/Interface-number. Two examples are:

• FastEthernet 0/0

• Serial 1/2

The slot numbers are as follows:

• 0 for all built-in interfaces

• 0 for all WIC interfaces

• 1 for interfaces in the lower network module slot

• 2 for interfaces in the upper network module slot

Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top.

Figure 1-8 shows an example of interface numbering on a Cisco 3631 router with:

• A WIC in each WIC slot (containing interfaces serial 0/0 and serial 0/1 in physical slot W0, and

interface serial 0/2 in physical slot W1)

• A 32-port asynchronous network module in slot 1 (containing interfaces serial 1/0 through serial

1/31)

• An alarm interface controller network module in slot 2 (internally connected to interface serial 2/0)

• One built-in Ethernet 10/100 interface—FastEthernet 0/0

Note The slot number for all WIC interfaces is always 0. (The W0 and W1 slot designations are for physical

slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are:

–

If slot W0 is empty and slot W1 contains a 1-port serial WIC, the interface in the WIC is numbered serial 0/0.

–

If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces in physical slot W0 are numbered serial 0/0 and serial 0/1, and the interface in physical slot W1 is numbered serial 0/2.

–

If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces in physical slot W0 are numbered serial 0/0 and serial 0/1, and the interface in physical slot W1 is numbered BRI 0/0.

Cisco 3660 Interfaces

Each individual network interface on a Cisco 3600 series router is identified by a slot number and port number.

Slot Numbering

The Cisco 3660 router chassis has six network module slots. Each network module slot accepts a variety of network module interface cards, supporting a variety of LAN and WAN technologies. Figure 1-9 shows the locations of the network module slots.

Slot 1

Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the port number; for example, Ethernet 0/0.

• Slot 0 contains fixed Fast Ethernet ports and is located at the top of the chassis.

• Slot 1 through Slot 6 accept up to six network modules.

Port numbers usually begin at 0 for each interface slot, and continue from right to left and, if necessary, from bottom to top. However, interface numbering for the Cisco 3660 series routers and for Ethernet and Token Ring network modules with two WAN interface card slots differs in the following ways:

• WAN interface card slot numbers always appear as slot 0, even if the interface card is installed in

the slot labeled W1.

• WAN interface cards are numbered dynamically, starting with the first card installed. For example:

–

If slot W0 is empty and slot W1 contains a 1-port serial WAN interface card, the interface number would be serial 0/0.

–

If slot W0 contains a 2-port serial WAN interface card and slot W1 contains a 1-port serial interface card, serial 0/0 and 0/1 would reside in slot W0 and serial 0/2 would reside in slot W1.

Voice Interface Numbering

Voice interfaces are numbered differently from WAN interfaces. Voice interfaces are numbered as follows:

interface-type chassis-slot/voice-module-slot/voice-interface

If you have a 4-channel voice network module installed in slot 1 of your router, the voice interfaces will be as follows:

• Chassis-slot 1, voice-network-module-slot 0, voice-interface 0, referred to as voice 1/0/0 (closest to

chassis-slot 0)

• Chassis-slot 1, voice-network-module-slot 0, voice-interface 1, referred to as voice 1/0/1

• Chassis-slot 1, voice-network-module-slot 1, voice-interface 0, referred to as voice 1/1/0

• Chassis-slot 1, voice-network-module-slot 1, voice-interface 1, referred to as voice 1/1/1 (farthest

from chassis-slot 0)

Safety Recommendations

Chapter 2 Preparing to Install the Router

• Locate the emergency power-off switch in the room in which you are working. Then, if an electrical

accident occurs, you can quickly turn off the power.

• Disconnect all power before doing the following:

–

Installing or removing a chassis

–

Working near power supplies

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power

extension cables, frayed power cords, and missing safety grounds.

• Do not work alone if hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

• If an electrical accident occurs, proceed as follows:

–

Use caution; do not become a victim yourself.

–

Turn off power to the device.

–

If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and then call for help.

–

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for it.

• Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at

the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing modules:

• Ensure that the router chassis 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 channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

• If no wrist strap is available, ground yourself by touching a metal part of the chassis.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should

be between 1 and 10 megohms (Mohm).

General Site Requirements

Site Environment

All Cisco 3600 series routers can be placed on a desktop or mounted in a rack. The Cisco 3620 and Cisco 3640 routers can also be installed on a wall. The location of your router and the layout of your equipment rack or wiring room are extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear panels of the router.

When planning your site layout and equipment locations, remember the precautions described in the next section, “Site Configuration” 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 may help you isolate the cause of the failures and prevent future problems.

Site Configuration

The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:

Chapter 2 Preparing to Install the Router

• Ensure that the room where your router operates has adequate circulation. Electrical equipment

generates heat. Without adequate circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.

• Always follow ESD-prevention procedures described in the “Preventing Electrostatic Discharge

Damage” section on page 2-2 to avoid damage to equipment. Damage from static discharge can

cause immediate or intermittent equipment failure.

• Ensure that the chassis cover or mainboard tray and module rear panels are secure. All empty

network module slots, WAN interface card slots, and power supply bays (in the Cisco 3660 router) must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings will create air leaks, which may interrupt and reduce the flow of air across internal components.

Cisco 3600 Series Routers Hardware Installation Guide

OL-2056-05

Chapter 2 Preparing to Install the Router

Equipment Racks

You can mount the Cisco 3620 and Cisco 3640 routers in a 19-inch rack (with a 17.5- or 17.75-inch opening), a 23-inch rack, or a 24-inch rack.

The Cisco 3631 and Cisco 3660 routers can be mounted in a 19-inch rack (with a 17.5- or 17.75-inch opening), or a 23-inch rack.

The following information will help you plan your equipment rack configuration:

• Allow clearance around the rack for maintenance.

• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each

router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake ports

or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated into the rack.

• Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through

the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.

General Site Requirements

• When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the

equipment by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to allow the router under test a maximum of cooling air and clean power.

Cisco 3600 Series Routers Hardware Installation Guide

OL-2056-05

Chapter 2 Preparing to Install the Router

Console and Auxiliary Port Considerations

The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the router either locally using a console terminal, or remotely using a modem connected to the auxiliary port. This section discusses important cabling information to consider before connecting a console terminal, which can be either an ASCII terminal or a PC running terminal emulation software, to the console port or modem to the auxiliary port.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, a message is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

Console and Auxiliary Port Considerations

The router has an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the cable.

For connection to a PC running terminal emulation software, your router is provided with an RJ-45 to DB-9 adapter cable.

To connect the router to an ASCII terminal, use an RJ-45 rollover cable and an RJ-45-to-DB-25 female adapter (not provided).

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware flow control. For detailed information about installing a console terminal, refer to the “Connecting to a Console Terminal or Modem” section on page 3-43.

For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.

Auxiliary Port Connections

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the cable.

For connection to a modem, your router is provided with an RJ-45-to-DB-25 adapter cable. For detailed information about connecting devices to the auxiliary port, refer to the “Connecting to a

Console Terminal or Modem” section on page 3-43.

For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.

Chapter 2 Preparing to Install the Router

Warning

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors.

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet implementations are as follows:

• 100BASE-T—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable.

• 10BASE-2—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment

distance is 607 feet (186 meters).

• 10BASE-5—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment

distance is 1,640 feet (500 meters).

• 10BASE-T—Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is

328 feet (100 meters). UTP cables look like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not meet.

Refer to the Cisco Modular Access Router Cable Specifications online document for information about Ethernet cables, connectors, and pinouts. This document is available online and on the Cisco Documentation CD-ROM.

Token Ring Connections

The IEEE has established Token Ring as standard IEEE 802.5. Specifications indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling.

Note To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make

sure that you use a shielded RJ-45 Token Ring cable when connecting your router to a Token Ring network.

Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the Token Ring must use the same operating speed.

Use a Token Ring cable to connect the router to a switch. Refer to the section “Token Ring Port Pinouts” in the Cisco Modular Access Router Cable Specifications online document for the Token Ring port pinouts. This document is available online and on the Cisco Documentation CD-ROM.

Serial Connections

Preparing to Connect to a Network

Serial connections are provided by WAN interface cards and network modules. For more information on WAN interface cards, refer to the Cisco Interface Cards Installation Guide. For more information on network modules, refer to the Cisco Network Modules Hardware Installation Guide. These documents are accessible online and on the Cisco Documentation CD-ROM.

Before you connect a device to a serial port, you need to know the following:

• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are

connecting to the synchronous serial interface

• Type of connector, male or female, required to connect to the device

• Signaling standard required by the device

Configuring Serial Connections

The serial ports on the asynchronous/synchronous serial network modules and the serial WAN interface card use DB-60 connectors. Serial ports can be configured as DTE or DCE, depending on the serial cable used.

Serial DTE or DCE Devices

A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE device provides a clock signal that paces the communications between the device and the router. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper to select either DTE or DCE mode.) Tab le 2-2 lists typical DTW and DCE devices.

Table 2-2 Typical DTE and DCE Devices

Device Type Gender Typical Devices

DTE Male

DCE Female

1. If pins protrude from the base of the connector, the connector is male.

2. If the connector has holes to accept pins, the connector is female.

Signaling Standards Supported

The synchronous serial ports available for the router support the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco DB-60 shielded serial transition cable that has the appropriate connector for the standard you specify. The documentation for the device you want to connect should indicate the standard used for that device. The router end of the shielded serial transition cable has a DB-60 connector, which connects to the DB-60 port on a serial WAN interface card. The other end of the serial transition cable is available with a connector appropriate for the standard you specify.

Chapter 2 Preparing to Install the Router

Terminal PC

Modem CSU/DSU Multiplexer

The synchronous serial port can be configured as DTE or DCE, depending on the attached cable (except EIA-530, which is DTE only). To order a shielded cable, contact customer service. See the “Obtaining

Technical Assistance” section on page xviii.

Note All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device.

Although manufacturing your own serial cables is not recommended (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the Cisco Modular Access Router

Cable Specifications document.

Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal significantly degrades or is completely lost.

Note Only the serial WAN interface card supports bit rates above 128 Kbps.

Table 2-3 lists the recommended maximum speeds and distances for each serial interface type; however,

you might get good results at speeds and distances greater than those listed, if you understand the electrical problems that might arise and can compensate for them. For instance, the recommended maximum rate for V.35 is 2 Mbps, but 4 Mbps is commonly used.

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232 signals. The recommended distance limits for EIA/TIA-449 shown in Table 2- 3 are also valid for V.35, X.21, and EIA-530. Typically, EIA/TIA-449 and EIA-530 can support 2-Mbps rates, and V.35 can support 4-Mbps rates.

Asynchronous/Synchronous Serial Module Baud Rates

The following baud-rate limitations apply to the slow-speed serial interfaces found in the asynchronous/synchronous serial modules:

• Asynchronous interface—Maximum baud rate is 115.2 kbps.

• Synchronous interface—Maximum baud rate is 128-kbps full duplex.

ISDN BRI Connections

The BRI WAN interface cards provide Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) connections. The BRI modules and BRI WAN interface cards are available with either an S/T interface that requires an external Network Terminator 1 (NT1), or a U interface that has a built-in NT1.

You can install the BRI modules in any available slot in the chassis.

Warning

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.

Use a BRI cable (not included) to connect the BRI WAN interface card directly to an ISDN. Table 2 -4 lists the specifications for ISDN BRI cables. Also, refer to the Cisco Modular Access Router Cable

Installing the Chassis

Depending on your router, you can set the chassis on a desktop, install it in a rack, or mount it on a wall or other flat surface. Select the procedure that best meets the needs of your network:

• Setting the Chassis on a Desktop, page 3-3

• Rack-Mounting the Chassis, page 3-3

• Wall-Mounting the Cisco 3620 Router, page 3-18

Note The Cisco 3640, Cisco 3661 and the Cisco 3660 routers cannot be wall-mounted.

Setting the Chassis on a Desktop

You can place Cisco 3600 series routers on a desktop or shelf. For Cisco 3620 routers only, attach the rubber feet supplied in the accessory kit. The procedure is as follows:

Installing the Chassis

Step 1 Place the router upside-down on a smooth, flat surface. Step 2 Peel the rubber feet off the black adhesive strip and place them adhesive-side down at each corner of the

underside of the chassis.

Step 3 Place the router top-side up on a flat, smooth, secure surface.

The following warning applies to Cisco 3660 routers:

Warning

Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg). Excessive weight

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit.

on top could damage the chassis.

After the router has been installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the “Installing Chassis Ground Connection” section on

page 3-19.

Rack-Mounting the Chassis

Statement 1032

OL-2056-05

If you are planning to rack-mount the router, do so before making network and power connections. If you need to install network modules or WAN and voice interface cards, you can do so either before or after rack-mounting the router. Ideally, you would install modules or WAN interface cards when you have the best access to the router’s rear panel.

Attaching Brackets to the Router

You can rack-mount a Cisco 3600 series router with either the front or the rear of the chassis facing forward. See the following sections for bracket installation instructions for each chassis orientation:

• Front-Panel-Forward Installation, page 3-6

• Rear-Panel-Forward Installation, page 3-9

• Center-Mount Installation, page 3-12

Note Use the screws supplied with the brackets for this installation.

Note If you are installing a Cisco 3620 or Cisco 3640 router in a 19-inch rack with a 17.5-inch opening, orient

the brackets so that they will not need to slide between the chassis and the rack; the 17.5-inch rack opening is not wide enough for the chassis plus the bracket thickness. (See Figure 3-6, Figure 3-7,

Figure 3-12 and Figure 3-13.)

Wall-Mounting the Cisco 3620 Router

This section explains how to mount the Cisco 3620 router on a wall.

Tip When choosing a wall-mounting location, consider cable limitations and wall structure.

The router is shipped with 19-inch rack-mount brackets, which can also be used for wall-mounting. If you ordered the 23- or 24-inch brackets, either pair could be used to wall-mount your router. The rubber feet are required to provide spacing between the wall and the router for ventilation and proper cooling.

Attaching Rubber Feet to the Router

Attach the rubber feet supplied in the accessory kit. Peel the rubber feet off the black adhesive strip and attach one rubber foot at each corner of the underside of the chassis.

Attaching Wall-Mount Brackets to the Router

Chapter 3 Installing the Router

To install the Cisco 3620 router on a wall, first attach the brackets on each side of the chassis as shown in Figure 3-30, using plastic washers and slotted hex-head screws. Position the washers so that the narrow shoulder faces the router chassis.

Note The hex-head screws and plastic washers are used only for wall-mounting the router. For rack-mounting,

the brackets are attached using Phillips-head screws, without washers.

Wiring the DC-Input Power Supply in Cisco 3631 Routers

If your router has a DC-input power supply, follow the directions in this section for proper wiring.

DC Wiring Requirements

A Cisco 3631 router with a DC-input power supply requires copper wire and crimp-type terminals for the power connections. Table 3- 2 summarizes the wiring requirements.

You can connect a single DC power source to either the A input or the B input. If there are dual power sources, connect one source to the A input and one source to the B input; both sources must be the same polarity and voltage.

Identifying a Rollover Cable

Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable. Hold the cables 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 wire connected to the pin on the outside of the right plug. (See Figure 3-65.) If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
