Caution

Ensure the device is not installed in close proximity to other devices which could lead to excessive pre-heating of air at the air intake of the router.

Caution

Your chassis installation must allow unrestricted airflow for chassis cooling.

Cisco 2800 Series Router Installation and Preventive Maintenance

Periodic inspection and cleaning of the external surface of the router is recommended to minimize the negative impact of environmental dust or debris on the router performance. The frequency of inspection and cleaning is dependent upon the severity of the environmental conditions. Cleaning involves vacuuming of router air intake and exhaust vents.

Caution

Fans are dynamic Electro-Mechanical devices. As such, fans can fail for various electronic reasons, and will eventually fail due to mechanical wear-out. Sites with ambient temperatures consistently above 25 degree C and with potentially high levels of dust or debris may require fan servicing.

Real-Time Clock

An internal real-time clock with battery backup provides the system software with time of day on system power up. This allows the system to verify the validity of the certification authority (CA) certificate. In the Cisco 2811, Cisco 2821, and Cisco 2851 routers, the clock and battery are permanently installed; the battery lasts the life of the router under the operating environmental conditions specified for the router. The Cisco operating environmental conditions specified for the router, and is not field-replaceable.

Interface Numbering

Table 7 summarizes the interface numbering on a Cisco 2801 series router. Ta ble 8 summarizes the

interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers.

Note

The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600 series routers.

On the Cisco 2801 router, the numbering format for slots is interface type 0/slot/port. “0” indicates slots that are built into the chassis of a router. On the Cisco 2801 router, all slots begin with “0,” because all slots are built into the chassis. Note that this is different from the Cisco Cisco

2851 routers. On these routers, some slots are built into the chassis and have slot numbers that

2811, Cisco 2821, and

begin with “0”. However, it is possible to have other slots that are part of a network module or an extension voice module. Those slots have slot numbers that begin with “1” or “2,” respectively.

Note

On the Cisco 2801 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an asynchronous interface, simply use the interface number to specify the async line. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0 on a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.

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.

•

Never open the enclosure of the router’s internal power supply.

•

If an electrical accident occurs, proceed as follows:

–

Use caution; do not become a victim yourself.

OL-5784-01

–

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.

General Site Requirements

•

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

This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, this section can also help you isolate the cause of failures and prevent future problems.

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

The device is designed for connection to TN and IT power systems.

The AC power supply includes the following features:

•

Autoselects either 110 V or 220 V operation.

Site Environment

Cisco 2800 series routers can be placed on a desktop or installed in a rack. This Cisco 2811 router can also be wall mounted. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations 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 “ environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Site Configuration,” to help avoid equipment failures and reduce the possibility of

OL-5784-01

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:

•

Ensure that the room where your router operates has adequate air circulation. Electrical equipment generates heat. Without adequate air 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 3 to avoid damage to equipment. Damage from static discharge can cause

immediate or intermittent equipment failure.

•

Ensure that the chassis cover and module rear panels are secure. All empty network module slots, interface card slots, and power supply bays 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 permits air leaks, which may interrupt and reduce the flow of air across internal components.

Equipment Racks

General Site Requirements

Note

Cisco 2800 series routers include brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 23-inch rack.

Brackets for a 23-inch rack are not available for Cisco 2801 routers.

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

•

Allow clearance around the rack for maintenance.

•

Allow at least one rack unit of vertical space between routers.

•

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 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.

•

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.

Port and Cable Information for Cisco 2800 Series Routers

This document provides information about cables needed to install your Cisco 2800 series integrated services router. It includes the following sections:

•

Console and Auxiliary Port Considerations, page 1

•

Preparing to Connect to a Network, page 2

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 connected to the console port, or remotely using a modem connected to the auxiliary port. This section discusses important cabling information to consider before connecting the router to a console terminal or modem.

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 send data at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

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 the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter (provided with the Cisco 2801 router only).

Corporate Headquarters: Cisco Systems, Inc., 170 West Tasman Drive, San Jose, CA 95134-1706 USA

Preparing to Connect to a Network

The default parameters for the console port are 9600 baud, 8 data bits, 1 stop bit, and no parity. The console port does not support hardware flow control. For detailed information about installing a console terminal, see the

For cable and port pinouts, refer to the online document Cisco Modular Access Router Cable

Specifications. This document is located on Cisco.com.

“Connecting to a Console Terminal or Modem” section on page 12.

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. (A DB-9-to-DB-25 adapter is also included with the Cisco 2801 router.)

For detailed information about connecting devices to the auxiliary port, see the “Connecting to a Console

Terminal or Modem” section on page 12 of the “Cable Connection Procedures for Cisco 2800 Series Routers” online document.

For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications online document on Cisco.com.

Preparing to Connect to a Network

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

Network connection considerations are provided for several types of network interfaces and are described in the following sections:

•

Ethernet Connections, page 3

•

Serial Connections, page 3

•

ISDN BRI Connections, page 5

•

10BASE-T—10 Mbps full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328

Refer to the Cisco Modular Access Router Cable Specifications online document for information about Ethernet cables, connectors, and pinouts.

Serial Connections

Serial connections are provided by WAN interface cards and network modules. For more information on WAN interface cards, refer to the network modules, refer to the Cisco Network Modules Hardware Installation Guide. These documents are accessible online at Cisco.com.

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

The Cisco 2801 and Cisco 2811 routers do not support the 1000BASE-T Ethernet implementation.

feet (100 meters).

Cisco Interface Cards Installation Guide. For more information on

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.)

OL-5785-01

Table 1 lists typical DTE and DCE devices.

Ta b l e 1 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.

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 of the “

” online document.

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

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 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

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

OL-5785-01

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 3 lists the specifications for ISDN BRI cables. Also, refer to the Cisco Modular Access Router Cable

http://www.cisco.com/en/US/docs/routers/access/2800/hardware/installation/guide/hw.html

For module and interface card compatibility information, see the data sheet for each module and interface card.

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Statement 1

You can set any Cisco 2800 series router on a desktop or install it in a rack. A Cisco 2811 router can also be mounted on a wall or other flat surface. See the applicable instructions in the following sections.

•

Rack-Mounting the Chassis

•

Setting the Chassis on a Desktop

•

Mounting a Cisco 2811 Router on a Wall

Caution

To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always hold the chassis by the metal body.

Rack-Mounting the Chassis

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 interface cards, you can do so either before or after rack-mounting the router. Ideally, you would install modules and interface cards when you have the best access to the rear panel of the router. Internal modules, such as advanced integration modules (AIMs) or packet voice data modules (PVDMs), should be installed prior to rack-mounting.

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 (with respect to ground) and voltage (within 0.25 volts). Do not connect –DC grounded and +DC grounded dual sources to Cisco 2811, Cisco 2821, and Cisco 2851 routers.

Caution

Dual sources with opposite-polarity grounding damage equipment.

In Figure 6, source A and source B share common positive terminal connections. This is allowed only if Va equals Vb (within 0.25 V).

Caution

When connecting source A and source B with common positive terminals, if source A and source B voltages are unequal by more than 0.25 V, the higher-voltage source can discharge into the lower-voltage source through the A- and B- input terminals. Excessive discharging currents through these terminals can cause one or both of the dual input DC power supply's internal A- or B- fuses to open, resulting in

Note

lack of redundancy or system failure. When source A and source B are within 0.25 V, discharge current is minimal.

When source A and source B are wired with common negative terminals, as in Figure 5, discharging does not occur and there is no restriction requiring that source A and source B voltages be equal.

Connecting Routers to Backup Power

If your router uses the Cisco Redundant Power System (RPS), refer to the Cisco Redundant Power

System Hardware Installation Guide for instructions about the power connections. You can access this

document at:

http://www.cisco.com/en/US/docs/routers/access/rps/hardware/installation/guide/rpshim.html.

Connecting WAN, LAN, and Voice Cables

Caution

Note

Before connecting the RPS to the router, make sure that either the RPS is in standby mode or the RPS AC power is disconnected. Connecting the RPS to AC power automatically places the RPS in active mode.

The Cisco 2801 router does not support an RPS.

Connecting WAN, LAN, and Voice Cables

This section describes how to connect the WAN, LAN, and voice interface cables. It covers the following topics:

•

Ports and Cabling, page 9

•

Connection Procedures and Precautions, page 11

One or two Ethernet cables are typically provided with the router. Additional cables and transceivers can be ordered from Cisco. For ordering information, contact customer service. For cable pinouts, refer to the

Cisco Modular Access Router Cable Specifications document.

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Warning

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

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.

Connecting to a Console Terminal or Modem

Connection Procedures and Precautions

Connect each WAN, LAN, and voice cable to the appropriate connector on the chassis or on a network module or interface card.

•

Position the cables carefully, so that they do not put strain on the connectors.

•

Organize cables in bundles so that cables do not intertwine.

•

Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition cables, if necessary.

•

Install cable ties in accordance with site requirements.

For cable pinouts, refer to the Cisco Modular Access Router Cable Specifications document.

Connecting to a Console Terminal or Modem

Your router has asynchronous serial console and auxiliary ports for system management. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

Cisco provides the following cables for connecting your router to a console terminal, PC, or modem:

•

One console cable (RJ-45-to-DB-9, blue)

•

One modem cable (RJ-45-to-DB-25, black) (Cisco 2811, Cisco 2821, and Cisco 2851 only)

•

One DB-9-to-DB-25 adapter (Cisco 2801 only)

This section describes how to connect a console terminal or PC to the console port and how to connect a modem to the auxiliary port.

Connecting to a Console Terminal or Modem

Connecting to the Console Port

If a console terminal or PC is connected to the console port, you can configure the router locally. To connect a console terminal or a PC running HyperTerminal or similar terminal emulation software to the console port on the router, perform the following steps:

Step 1

Step 2

Use the blue RJ-45-to-DB-9 console cable to connect the router to a terminal.

Note

Configure your terminal or terminal emulation software for 9600 baud (default), 8 data bits, 1 stop bit, no parity, and flow control set to “none.”

Note

On the Cisco routers, the console port is color-coded blue.

Because hardware flow control is not possible on the console port, do not connect modems to the console port. Connect modems only to the auxiliary port.

Connecting to the Auxiliary Port

If a modem is connected to the auxiliary port, a remote user can dial in to the router and configure it. To connect a modem to the auxiliary port on the router, perform the following steps:

Step 1

Step 2

Use the black RJ-45-to-DB-25 modem cable or the RJ-45-to-DB-9 console cable with a DB-9 to DB-25 adapter to connect the router to a modem.

Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115200 bps is supported) and hardware flow control with data carrier detect (DCD) and data terminal ready (DTR) operations.
