CHAPTER

Overview of the Routers

Cisco Integrated Services Routers Generation 2 (ISR G2) offer data functionality through Gigabit Ethernet ports and security functionality with a virtual private network (VPN) accelerator on the motherboard. Additional security features are available with add-on hardware and software.

Cisco 2900 series and Cisco 3900 series routers also provide voice IP telephony with digital signal processor (DSP) capability; and voice gateway, DSP farm, IP-to-IP gateway, Cisco Unified Communications Manager Express (CUCME) via Cisco IOS. Cisco Unity Express (CUE) is provided through the use of add-on hardware.

This series of ISRs have new slots that support next generation Enhanced High-Speed WAN Interface Cards (EHWICs), Internal Services Modules (ISMs), Packet Voice Data Modules (PVDM3s), Service Modules (SMs), and Services Performance Engines (SPEs).

Access to the Cisco Multi-Gigabit Fabric (MGF) facilitates connection between switch ports on the ISR without utilizing all of the external ports. A logical GE interface on the ISR connects external and internal modules through the MGF for improved LAN and WAN switching.

Gigabit Ethernet Ports

There are two different types of Gigabit Ethernet (GE) ports available on Cisco 2900 series and Cisco 3900 series ISRs.

Hardware Features

Auxiliary, RJ-45

GE Ports

SFP Ports

The GE RJ-45 copper interface ports support 10BASE-T, 100BASE-TX, and 1000BASE-T.

The small-form-factor pluggable (SFP) ports support 1000BASE-LX/LH, 1000BASE-SX, 1000BASE-ZX, and Coarse Wavelength-Division Multiplexing (CWDM-8) modules, as well as 100Mbs SFP modules.

The SFP port shares the same physical port as an RJ-45 GE port. Tabl e 1-4 on page 1-16 shows the models that support SFP installation. The SFP port supports auto-media-detection, auto-failover and remote fault indication (RFI), as described in the IEEE 802.3ah specification.

Use the media-type {rj45{auto-failover}} | {sfp{auto-failover}} command to enable the auto-media-detection and auto-failover features. Use the

Command Lookup Tool for details about this

command.

The SFP port can be configured for the following behaviors:

•

Always use the RJ-45 port.

•

Always use the SFP port.

•

Always use the RJ-45 port but fail over to the SFP port if the RJ-45 port fails. This is the default configuration.

•

Always use the SFP port but fail over to the RJ-45 port if the SFP port fails.

USB Serial Console Port

The Mini-USB type B serial port has been enabled to perform management tasks on the router. To use this port, you must install a Windows USB device driver before establishing physical connectivity between a personal computer and the router. See the

Device Driver” section on page 3-36 for driver installation instructions.

Note

The SPE 200 and the SPE 250 include a cryptographic accelerator for improved security performance. See the “Cryptographic Accelerator” section on page 1-27 for more information.

Service Modules

Service Modules (SM) are the largest modules on Cisco 2900 series and Cisco 3900 series ISRs. With the largest form-factor and power capacity, these modules deliver high-performance service applications. SMs are physically larger than legacy network modules, as a result, network modules require an adapter for installation. See the Installing Cisco Network Modules in Cisco Access Routers guide for installation instructions,

http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/InstNetM. html.

Enhanced High-Speed WAN Interface Cards

Enhanced High-Speed WAN Interface Card (EHWICs) are the latest generation of interface cards. EHWICs are installed in the EHWIC slot on the router. Legacy interface cards, such as WAN interface cards (WICs), voice interface cards (VICs), high-speed WAN interface cards (HWICs), double-width high-speed WAN interface cards (DHWICs), and (EHWICs) are supported in the EHWIC slot on the router.

Services Performance Engine 200 and Services Performance Engine 250 support the following legacy interface cards in the EHWIC slots. (See

Cisco 2900 series and Cisco 3900 series ISRs support a variety of power supply configurations. All power supplies are field replaceable and externally accessible with the exception of the Cisco 2901 ISR. The Cisco 2901 ISR has an internal power supply, which requires removing the cover for replacement.

If configured with dual power supplies or an Redundant power supplies (RPS), the power supplies are hot swappable. RPSs require an RPS adapter. There are two versions of the RPS adapter, one for the Cisco 2911 and one for the Cisco 2921 and 2951. Both use the Cisco Redundant Power System 2300.

Configurations include AC and DC (with and without IP), Dual DC, internal POE, and POE boost.

how to configure and manage power going to modules and peripherals.

Fans, Ventilation, and Airflow

The Cisco 2911 and Cisco 3900 series ISRs have optional fan filters that are easy to replace. The filters may be used to meet Network Equipment Building Systems (NEBS) requirements, or to operate in dusty environments. When a filter becomes dirty, discard it and replace it with a new one. See the

a Fan Tray or Air Filter” section on page 5-45.

Fan speeds are controlled by the fan speed controller circuitry. To minimize noise, the fans operate at one of several predetermined speeds and are dependent on the input ambient air temperature.

Secure Key

A hardware secure key storage unit is provided on the Cisco 3925 and Cisco 3945 routers to safely store passwords and credentials. The secure key storage unit is a self-contained tamper-resistant computer key-store that acts as a black box for credential storage by accepting credentials and never returning them.

Cryptographic Accelerator

Cisco 3925E and Cisco 3945E ISRs ship with a Services Performance Engine that includes an onboard cryptographic accelerator. It shares security processing for SSLVPN and IPSec. By default, acceleration of SSL is disabled so IPSec performance is maximized.

If you want to set up the router as an SSLVPN gateway, enable the SSLVPN feature with the crypto engine accelerator bandwidth-allocation ssl fair command. To learn more about the cryptographic accelerator, see the Configuring the Security Features module in the Cisco 3900 series, 2900 series, and 1900 series Integrated Services Routers Software Configuration Guide at Cisco.com.

Slot, Port, and Interface Information

Table 1-11 and Tabl e 1-12 show slot, port, and interface numbering ranges.

On the Cisco 2901 router, the numbering format for slots and ports is defined as follows: interface type 0/slot/port. “0” indicates slots that are built into the chassis of a router. On the Cisco 2901 router, all slots begin with “0,” because all slots are built into the chassis. On the Cisco 3900 series routers, some slots are built into the chassis and some are external.

Slots that are part of a network module or an extension voice module have numbers that begin with “1” or “2,” respectively. See the module documentation for more information.

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 ground.

Chapter 2 Preparing for Router Installation

•

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 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.

Rack Requirements

Some Cisco 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.

The following information can 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.

OL-18712-02

Page 71

Chapter 2 Preparing for Router Installation

•

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 it.

•

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 in the rack.

Router Environmental Requirements

Cisco 2900 series routers can be placed on a desktop or installed in a rack. The Cisco 2901 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, refer to the “General Site Requirements”

section on page 2-4, section. If you are currently experiencing shutdowns or an unusually high number

of errors with your existing equipment, these precautions and recommendations may help you isolate the cause of failure and prevent future problems.

•

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.

Router Environmental Requirements

•

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

Damage” section on page 2-4 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.

•

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.

Power Guidelines and Requirements

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.

The AC power supply includes the following features:

•

Autoselects either 110 V or 220 V operation.

•

All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates the correct voltage, frequency [AC-powered systems only], current draw, and power dissipation for the unit.)

Network Cabling Specifications

The following sections describe the cables needed to install your Cisco 2900 and 3900 series ISR in the following sections:

•

Console and Auxiliary Port Considerations, page 2-7

•

Preparing for Network Connections, page 2-9

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

Network Cabling Specifications

Console Port Connections

The router has both EIA/TIA-232 asynchronous (RJ-45) and USB 5-pin mini Type B, 2.0 compliant serial console ports. The console ports do not have any hardware flow control. Shielded USB cables with properly terminated shields are recommended.

EIA/TIA-232

Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the cable. Only one port can be used at the same time.

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, see the Cisco Modular Access Router Cable Specifications document located at 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 USB Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.

Note

Always use shielded USB cables with a properly terminated shield.

Network Cabling Specifications

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

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

“Installing the Cisco Microsoft Windows USB Device Driver” section on page 3-36.

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, and 115200 bps.

Network Cabling Specifications

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.)

Ta b l e 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.

Chapter 2 Preparing for Router Installation

Table 2-2 lists typical DTE and DCE devices.

Ter minal

CSU/DSU

Multiplexer

Signaling Standards Supported

The synchronous serial ports available for the router support the following signaling standards: they are 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).

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.

Cisco Modular Access Router

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

Unpacking the Router

Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to install the router, proceed with unpacking it.

The router, accessory kit, publications, and any optional equipment you ordered may be shipped in more than one container. When you unpack the containers, check the packing list to ensure that you received all of the items on the list.

Installing the Router

If you need to install service modules, interface cards, and FRUs, you can install them either before or after you install the router. Ideally, you install modules and interface cards when you have the best access to the back panel of the router. Internal modules and FRUs, such as internal services modules (ISMs) or packet voice data modules (PVDMs), and fan trays should be installed before rack-mounting. See the

“Installing and Upgrading Internal Modules and FRUs” section on page 5-1.

There are three methods of installing the router:

•
