The Cisco 3900 series, 2900 series, and 1900 series integrated services routers (ISRs) offer secure, wire-speed delivery of concurrent data, voice, and video services. The modular design of these routers provides maximum flexibility, allowing you to configure your router to meet evolving needs.
The routers offer features such as hardware-based virtual private network (VPN) encryption acceleration, intrusion-protection and firewall functions, and optional integrated call processing and voice mail. A wide variety of legacy network modules and interfaces, service modules (SMs), internal services modules (ISMs), next-generation packet voice/data modules (PVDM3), Services Performance Engines (SPEs), high-density interfaces for a wide range of connectivity requirements, and sufficient performance and slot density for future network expansion requirements and advanced applications are available.
Power-saving hardware and software features are incorporated throughout the series. These routers provide access to the multi-gigabit fabric, which provides a connection between switch ports without using up external ports. The logical Gigabit Ethernet (GE) interface on the router connects external and internal modules through the backplane for LAN and WAN switching. Software feature upgrades are provided through software licensing.
The following sections describe the Cisco 3900 series, 2900 series, and 1900 series ISRs:
Cisco 3900 series routers with either Services Performance Engine 200 or Services Performance Engine 250 have an onboard cryptographic accelerator that is shared between SSLVPN and IPSec. By default, acceleration of SSL is disabled so IPSec performance is maximized.
Cisco 3900 series, 2900 series, and 1900 series ISRs provide an additional mechanism for configuring the system through a USB2 serial console port. The traditional RJ-45 serial console port is also available.
Some modules and interface cards that are inserted in new slots provide hardware and software power management features described below:
•High efficiency AC power supplies
•Electrical components with built-in power saving features, such as RAM select and clock gating
•Ability to disable unused clocks to modules and peripherals
•Ability to power down unused modules and put peripherals into a reset state, put front panel ports and unused internal components in a shutdown or reset state
Advanced Capability CompactFlash
Cisco 3900 series, 2900 series, and 1900 series ISRs use Advanced Capability CF3 memory to store the system image, configuration files, and some software data files.
SFP/Gigabit Ethernet Port
Cisco 2921, Cisco 2951 and Cisco 3900 Series routers have an SFP/Gigabit Ethernet port that supports copper and fiber concurrent connections. Media can be configured for failover redundancy when the network goes down. For more information, see the "Configuring Backup Data Lines and Remote Management" section.
New Modules and Interface Cards
Cisco 3900 series, 2900 series, and 1900 series ISRs introduce the following new modules and interface cards, which are inserted in the following new router slots:
Note See the router's product page at Cisco.com for a complete list of supported modules and interfaces.
Multi-Gigabit Fabric Communication
Cisco 3900 series, 2900 series, and 1900 series ISRs use a MGF4 for the new modules and interface cards to inter-communicate on the router. Legacy modules that support Cisco HIMI5 also support MGF to inter-communicate on the router. Next generation module drivers integrate with the MGF to perform port configurations, configure packet flow, and control traffic buffering. All configurations are performed from the module-side, which may or may not lead to changes on the MGF. For more information, see the "Configuring Multi-Gigabit Fabric Communication" section.
Integrated Application Services Features
Cisco 3900 series, 2900 series, and 1900 series ISRs offer integrated security features and voice features.
4Does not support Voice application services. Includes embedded wireless access point that supports Cisco Unified Wireless Architecture.
Cisco 3900 series, 2900 series, and 1900 series ISRs have introduced new slots on the chassis. The first column in Table 3 lists the new slot names. The second column lists the corresponding old slot names. Modules previously inserted in the old slots now insert in the new slots with the help of an adapter card.
For instance, network modules (NMs), enhanced network modules (NMEs), and extension voice modules (EVMs) use an adapter, or carrier card, to insert into the SM slot. See your router's hardware installation guide for adapter information.

The following ports are common among Cisco 3900 series, 2900 series, and 1900 series routers:
•Gigabit Ethernet RJ45—Ports available through an RJ45 connector.
•Gigabit Ethernet RJ45/SFP—Ports available through RJ45- SFP connectors. Connection supports fail-over if the secondary connection goes down.
•RS232 Aux—Supports modem control lines and remote administration for box-to-box redundancy applications.
•RS232 Serial Console—Supports modem control lines and remote administration of the router with the proprietary cable shipped in the box.
•Type A USB 2.0—Supports USB-based flash memory sticks, security tokens, and USB-compliant devices.
•Type B mini-port USB Serial Console—Supports modem control lines and remote administration of the router using a type B USB-compliant cable.
Cisco 3900 series, 2900 series, and 1900 series ISRs support Cisco IOS software entitlement. Your router is shipped with the software image and the corresponding permanent licenses for the technology packages and features that you specified preinstalled. You do not need to activate or register the software prior to use. If you need to upgrade or install a new technology package or feature see Software Activation on Integrated Services Router,
See the router-specific hardware installation guide to install the router in an appropriate location. Connect the router with the appropriate cables. Supply power to the router and perform the initial software configuration using Cisco Configuration Professional Express. After the initial configuration is completed, perform the following steps:
