Cisco 3900 Series
Series Features Overview
The Cisco 3900 Series is architected to meet the application demands of today's branch offices with design
flexibility for future applications. The modular architecture is designed to support increasing bandwidth
requirements, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to
modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). The table below
lists the architectural features and benefits of the Cisco 3900 Series.
Architectural Features Description
Modular Platform • The Cisco 3900 Series routers are highly modular platforms with several
types of module slots to add connectivity and services for varied branch-
office network requirements.
• The routers offer an industry-leading breadth of LAN and WAN
connectivity options through modules to accommodate field upgrades
to future technologies without requiring platform replacement.
• The Cisco Services Performance Engine (SPE) on the Cisco 3900
offers the ability to increase the performance of the router with a field-
upgradable motherboard as your network needs grow.
Processors • The Cisco 3900 Series are powered by high-performance multi-core
processors that can support the growing demands of high-speed WAN
connections to the branch-office while also running multiple concurrent
services.
Embedded IP Security with • Embedded hardware encryption acceleration is enhanced to provide
higher scalability, which, combined with an optional Cisco IOS Security
Security Sockets Layer
(IPsec/SSL) VPN Hardware license, enables WAN link security and VPN services (both IPsec and
Acceleration SSL acceleration).
• The onboard encryption hardware out-performs the advanced
integration modules (AIMs) of previous generations.
• The Cisco 3900 Series introduces an innovative multigigabit fabric
Multigigabit Fabric (MGF)
(MGF) that allows for efficient module-to-module communication,
enabling tighter services interactions across modules while reducing the
overhead on the router processor.
TDM Interconnectivity • Unified communications services in the branch office are significantly
Fabric enhanced with the use of TDM interconnectivity fabric in the router
architecture, allowing for scaling of DS-0 channel capacity.
Integrated Gigabit Ethernet • The Cisco 3900 Series provides three 10/100/1000 Ethernet WAN ports.
Ports
• Two of the three 10/100/1000 Ethernet WAN ports on the Cisco 3900
Series can support Small Form-Factor Pluggable (SFP)-based
connectivity in lieu of RJ-45 ports enabling fiber connectivity.
Innovative Universal- • A new, innovative, mini-B USB console port supports management
Serial-Bus (USB)-based connectivity when traditional serial ports are not available.
Console Access
• Traditional console and auxiliary ports are also available.
Optional Integrated Power • An optional upgrade to the internal power supply provides inline power
Supply for Distribution (802.3af-compliant PoE, Enhanced PoE, and Cisco Inline Power) to
of PoE and Universal optional integrated switch modules.
DC Power Supply
• On the Cisco 3925 and 3945 routers, an optional DC power supply will be
available in the future that extends possible deployment environments
such as central offices and industrial environments.

Architectural Features Description
• Both the Cisco 3925 and 3945 allow for power redundancy through
Optional Integrated
Redundant Power Supply the use of an optional integrated redundant power supply, thereby
(RPS) and PoE Boost decreasing network downtime and protecting the network from power-
supply failures.
• When populated with dual integrated power supplies, the Cisco 3925
and 3945 can operate in a configurable PoE boost mode in lieu of
redundant power mode whereby the power capacity of the platform
is increased to almost twice the normal power to support additional
PoE ports.
Designed for Flexible • Both the Cisco 3925 and 3945 are designed for NEBS environments.
