Overview of the Router

The Cisco 1900 Series Integrated Services Routers (ISRs) are modular routers with LAN and WAN connections that can be configured by means of interchangeable interface cards and internal service modules (ISMs). The series currently consists of the 1905, 1921, 1941, and 1941W (wireless) models. The 1941W is Wi-Fi CERTIFIED™ and 802.11a/b/g/n-compliant. The modular design of the routers provides flexibility, allowing you to configure your router according to your needs.

This ISR series has new slots that support next generation Enhanced High-Speed WAN Interface Cards (EHWICs), Internal Services Modules (ISMs, 1941 only), and 2 CompactFlash cards (1941 only). Universal serial bus (USB) ports are available for USB devices, and a USB mini Type-B serial console port is available in addition to the RJ-45 console connector.

Chassis Ventilation

An internal fan provides chassis cooling. An onboard temperature sensor controls the fan speed. The fan is always on when power is applied to the router. Under most conditions, the fan operates at the slowest speed to conserve power and reduce fan noise. It operates at the higher speeds when necessary under conditions of higher ambient temperature. See the

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. The Cisco

1900 series router has a lithium battery. This battery lasts the life of the router under the operating

environmental conditions specified for the router, and is not field-replaceable.

Warning

Dispose of used batteries according to the manufacturer’s instructions.

Chassis Security

The chassis of the router is constructed with a KensingtonTM security slot on the back panel. It can be secured to a desktop or other surface by using Kensington

Wireless LAN Connectivity

The embedded Wi-Fi CERTIFIED™, 802.11a/b/g/n-compliant wireless access point is preinstalled in the router as an optional feature. The Cisco 1900 series routers support both autonomous and unified features and network configurations.

The wireless access point does not have an external console port for connections. To configure the wireless device, you must use a console cable to connect a PC to the host router’s console port as described in command-line interface (CLI) to access the interface.

Table 1-5 describes the radios and antennas for the Cisco 1900 series wireless routers.

Interface Numbering

Baud Reset Button

The Cisco 1905 and Cisco 1921 ISRs have a baud reset button on the back panel. When the button is pressed during power on, ROMMON resets the router to the default console port configuration. If the baud reset button is pressed for longer than 30 seconds, the router defaults to the read-only ROMMON image. The default console port configuration is 9600 control is set to none.

Interface Numbering

Each individual interface (port) on a Cisco 1900 series router is identified by a number. The Cisco 1900 series routers contains the following wide-area network (WAN) and local-area network (LAN) interface types:

• Two onboard Gigabit Ethernet (GE) LAN interfaces

• Two slots in which you can install WICs, VWICs (data only), and HWICs. The Cisco 1905 comes

with a factory installed EHWIC in the right slot.

Chapter 1 Overview of the Router

baud, 8 data bits, 1 stop bit, no parity, and flow

The numbering format for the slots is interface-type 0/slot-number/interface-number. Tab le 1-6 summarizes the interface numbering. See Figure 1-5 to identify the slot numbers.

Ta b l e 1-6 Interface Numbering

Slot Number Slot Type Slot Numbering Range

Onboard Ports 10/100/1000 Ethernet 0/0 and 0/1

Slot 1 EHWIC/WIC/VWIC 0/1/0 to 0/1/0 (single or double-wide)

Note On the Cisco 1900 series router, the numbering format for configuring an async interface is 0/slot/port. To

configure the line associated with an async interface, simply use the interface number to specify the async line. For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in slot 1.

–

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

–

Determine whether 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 is 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. ESD 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.

General Site Requirements

• 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

This section describes the requirements that 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.

Site Environment

The Cisco 1900 series router is designed for placement on a desktop, rack-mounted or wall mounted.

The location of your router is an extremely important consideration for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can also make maintenance difficult. Plan for access to both front and back panels of the router.

When planning your site layout and equipment locations, remember the precautions described in the

“Site Configuration” section on page 2-4 to help avoid equipment failures and reduce the possibility of

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.

Statement 1007

the correct voltage, frequency, current draw, and power dissipation for the unit.)

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:

• Make sure 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. See the

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

Damage” section on page 2-3 to avoid damage to equipment. Damage from static discharge can

cause immediate or intermittent equipment failure.

• Make sure that the chassis cover and module back panels are secure. All empty interface card slots

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 creates air leaks, which may interrupt and reduce the flow of air across internal components.

Chapter 2 Preparing for Router Installation

Wireless LAN Considerations

Wireless communication is dependent upon the propagation of radio waves. Many environmental factors influence radio waves. The Cisco Multiband Swivel-Mount Dipole Antenna document Installation Notes section describes factors affecting this. Prior to determining a location for the router it is advisable you review these factors.

http://www.cisco.com/en/US/docs/routers/access/wireless/hardware/notes/antdip.html#wp1009743

The type of antenna used with your wireless router and its location greatly impact the quality of wireless connections to the router. Cisco 1900 series wireless routers are compatible with three different antenna types—swivel-mount dipole antennas that mounts on the back panel of the router, a wall-mount antenna, and a ceiling-mount antenna.

For more information about antenna coverage and optimal usage, see the following documents:

• Cisco Multiband Swivel-Mount Dipole Antenna

• Cisco Multiband Diversity Omnidirectional Ceiling-Mount Antenna

Network Cabling Specifications

The following sections describe the cables needed to install your Cisco 1900 series ISR in the following sections:

• Console and Auxiliary Port Considerations, page 2-5

• Preparing to Connect to a Network, page 2-7

For cable connection procedures, see the “Cable Connection Procedures for Cisco 1900 Series Routers” document.

Console and Auxiliary Port Considerations

The router includes USB, asynchronous serial and auxiliary ports. 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 provides 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 flow control, whereas 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) and at least one USB Type-A

2.0 compliant ports. See

OL-19084-02

Tabl e 1-1 on page 1-8 for a list of ports.

Cisco 1900 Series Hardware Installation

2-5

Console and Auxiliary Port Considerations

EIA/TIA-232 Port

Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE) or data communications equipment (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 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).

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

Connection Procedures for Cisco 1900 Series Routers” document.

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

Specifications. This document is located on Cisco.com.

USB Serial Console

The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin mini Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.

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

Connection Procedures for Cisco 1900 Series Routers” document.

Chapter 2 Preparing for Router Installation

“Connecting to the Console Port with Microsoft Windows” section on page 5-4 of the “Cable

For operation with Microsoft Windows, the Cisco Windows USB Console Driver must be installed on any PC connected to the Console port. If it is not installed, prompts guide you through a simple installation process.

The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.

Only one console port can be active at a time. When a cable is plugged into the USB console port the RJ

45 port becomes inactive. Conversely, when the USB cable is removed from the USB port the RJ 45

port becomes active.

Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps.

Note 4-pin mini Type-B connectors are easily confused with 5-pin mini Type-B connectors. They are

not compatible Only the 5-pin mini Type-B can be used.

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)—that

you are connecting to the synchronous serial interface

• Type of connector—male or female—that is required for connecting to the device

• Signaling standard that is required by the device

Configuring Serial Connections

The serial ports on the serial WICs use DB-60 connectors. Serial ports can be configured as DTEs or DCEs, 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 for the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper that allows you to select either DTE mode or DCE mode.) 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 that 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 WIC. The other end of the serial transition cable is available with a connector appropriate for the standard that 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

Documentation and Submitting a Service Request” section on page -xvi.

Chapter 2 Preparing for Router Installation

Although we do not recommend manufacturing your own serial cables (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the

Cable Specifications.

Transmission Speeds and 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 is significantly degraded or is completely lost.

Table 2-2 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

Distance for USB

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232 signals. Typically, EIA/TIA-449 and EIA-530 can support a 2-Mbps rate, and V.35 can support a 4-Mbps rate.

Asynchronous/Synchronous Serial Module Baud Rates

The following baud-rate limitations apply to the slow-speed serial interfaces 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 WICs provide Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) connections. BRI WICs are available with either an S/T interface that requires an external Network Termination 1 (NT1), or a U interface that has a built-in NT1. You can install the BRI WICs in any available WIC slots in the chassis.

Cable Information and Specifications for Cisco 1900 Series Routers

This document gives cable information and specifications for the console port, auxiliary port, and network ports on your Cisco 1900 series integrated services router. It contains the following sections:

• Console and Auxiliary Port Considerations, page 3-1

• Preparing to Connect to a Network, page 3-3

For cable connection procedures, see the “Cable Connection Procedures for Cisco 1900 Series Routers” document.

Console and Auxiliary Port Considerations

The router includes USB, asynchronous serial and auxiliary ports. 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 provides important cabling information to consider before connecting the router to a console terminal or modem.

3

The main difference between the console and auxiliary ports is that the auxiliary port supports flow control, whereas 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) and two USB Type-A 2.0 compliant ports.

EIA/TIA-232 Port

Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE) or data communications equipment (DCE) device at the end of the cable.

OL-19084-01

Cisco 1900 Series Hardware Installation

Console and Auxiliary Port Considerations

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

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

Connection Procedures for Cisco 1900 Series Routers” document.

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

Specifications. This document is located on Cisco.com.

USB Serial Console

The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin mini Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.

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

Connection Procedures for Cisco 1900 Series Routers” document.

For operation with Microsoft Windows, the Cisco Windows USB Console Driver must be installed on any PC connected to the Console port. If it is not installed, prompts guide you through a simple installation process.

The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.

Chapter 3 Cable Information and Specifications for Cisco 1900 Series Routers

“Connecting to the Console Port with Microsoft Windows” section on page 5-4 of the “Cable

Only one console port can be active at a time. When a cable is plugged into the USB console port the RJ

45 port becomes inactive. Conversely, when the USB cable is removed from the USB port the RJ 45

port becomes active.

Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps.

Note 4-pin mini Type-B connectors are easily confused with 5-pin mini Type-B connectors. They are

not compatible Only the 5-pin mini Type-B can be used.
