The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be
determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications to this product not authorized by Cisco could void the FCC approval and negate your authority to operate the product.

This guide explains how to install, connect, and perform initial configurations for the Cisco 2900 series
and Cisco 3900 series Integrated Services Routers (ISRs). Some information may not apply to your
specific router model.
Note For warranty, service, and support information, see the “Cisco Warranty Terms” section in the
Readme First for the Cisco 1900 Series, 2900 Series, and 3900 Series Integrated Services
Routers document that was shipped with your router.
This guide is intended for Cisco equipment providers and service persons who are technically
knowledgeable and familiar with Cisco routers and Cisco IOS software and features. They would
understand how to install, configure, and maintain the router, and they should be familiar with electronic
circuitry and wiring practices, and have experience as an electronic or electromechanical technician.
This guide identifies certain procedures that should be performed only by trained and qualified
personnel.

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.

Chassis Views
This section contains views of the front and back panels of the Cisco 2900 series and Cisco 3900 series
routers, showing locations of the power and signal interfaces, module slots, status indicators, and chassis
identification labels.
Note Routers support the following slot types: Service Modules (SMs), Enhanced High-Speed Interface Card
(EHWICs), high-speed WAN interface cards (HWICs), voice WAN interface cards (VWICs), WAN
interface cards (WICs), Internal Services Modules (ISMs), and packet voice DSP modules (PVDM3s).
However, some router models do not support all of these media types. See the router model descriptions
for more information.
