Cisco 2900 Series
Modularity Features and Benefits
The Cisco 2900 Series provides significantly enhanced modular capabilities (refer to Table 3) offering
investment protection for customers. Most of the modules available on previous generations of Cisco
routers, such as the Cisco 2800 Series, are supported on the Cisco 2900 Series. Additionally, modules can
be used on other supported Cisco platforms to provide maximum investment protection. Taking advantage
of common interface cards across a network greatly reduces the complexity of managing inventory
requirements, implementing large network rollouts, and maintaining configurations across a variety of
branch-office sizes.
A complete list of supported modules, including a list of supported SFPs for the Cisco 2900 Series, is
available at: http://www.cisco.com/go/2900.
ISR Modules Description
Cisco Service Module • Each service module slot offers high-data-throughput capability:
- Up to 4 Gbps aggregate toward the route processor
- Up to 2 Gbps aggregate to other module slots over MGF
• Service module (SM) slots are highly flexible with support for double-
wide service modules (SM-D's), which are Service Modules that
require two SM slots. SM-Ds in the Cisco 2921 and 2951 provide
flexibility for higher-density modules.
• A service module slot replaces the network module and the extension
module for voice/fax (EVM) slots and is offered on Cisco 2911, 2921,
and 2951 ISRs.
• An adapter module enables backward compatibility with existing
network modules, enhanced network modules (NMEs), and EVMs.
• Service module slots provide twice the power capabilities relative to
the network-module slots, allowing for flexibility for higher-scale and
better-performance modules.
• Power to service module slots can be managed by extensions similar
to the Cisco EnergyWise framework, so your organization can reduce
energy consumption in your network infrastructure. Full EnergyWise
support will be available in future software releases.
Cisco Enhanced High-Speed WAN • The EHWIC slot provides enhancements to the prior generation's
Interface Card (EHWIC) high-speed WAN interface card (HWIC) slots while provide maximum
investment protection by natively supporting HWICs, WAN interface
cards (WICs), voice interface cards (VICs), and voice/WAN interface
cards (VWICs).
• Four integrated EHWIC slots on the Cisco 2901, 2911, 2921, and 2951
allow for more flexible configurations.
• Each HWIC slot offers high-data-throughput capability:
- Up to 1.6 Gbps aggregate toward the route processor
- Up to 2 Gbps aggregate to other module slots over the MGF
• Flexibility to support double-wide modules is enabled by combining
two EHWIC slots. Up to 2 double-wide HWIC (HWIC-D) modules are
supported.

Modularity Features and Benefits
ISR Modules Description
Cisco Internal Services Module (ISM) • A single ISM slot provides flexibility to integrate intelligent service
modules on an internal slot within the chassis
• Each ISM slot offers high-data-throughput capability:
- Up to 4 Gbps aggregate toward the route processor
- Up to 2 Gbps aggregate to other module slots over the MGF
• The ISM replaces the AIM slot; existing AIM modules are not
supported in the ISM slot.
• Power to ISM slots can be managed by extensions similar to the Cisco
EnergyWise framework, so your organization can reduce energy
consumption in your network infrastructure. Full EnergyWise support
will be available in future software releases.
Cisco High-Density Packet Voice • PVDM3 slots natively support PVDM3 modules, providing support for
Digital Signal Processor (DSP) richer density for rich-media voice and video.
Module (PVDM3) Slots
• Each PVDM3 slot connects back to the system architecture through a
on Motherboard
2 Gbps aggregate link through the MGF.
• Investment protection for PVDM2 modules is supported through an
adapter module.
• Power to the PVDM slots can be managed by extensions similar to
the Cisco EnergyWise framework, so your organization can reduce
energy consumption in your network infrastructure. Full EnergyWise
support will be available in future software releases.
Compact Flash Slots • Two external Compact Flash slots are available on the Cisco 2900
Series Integrated Services Routers. Each slot can support high-speed
storage densities upgradeable to 4 GB in density.
USB 2.0 ports • Two high-speed USB 2.0 ports are supported. The USB ports enable
secure token capabilities and storage.
