Overview of Cisco Interface Cards for Cisco Access Routers

Revised: 12/03/2011, OL-12796-03

Overview

This document provides an overview of Cisco interface cards used in Cisco access routers, and contains the following sections:

Introduction to Cisco Interface Cards

Cisco interface cards are classified according to the technologies they support. For example, WAN interface cards (WICs) support WAN technologies, such as Gigabit Ethernet; and voice interface cards (VICs) support voice technologies. Voice/WAN interface cards (VWICs) can support voice, data, and voice and data applications, depending on the capabilities of the router in which the VWIC is installed. Enhanced High-speed WAN interface cards (EHWIC) provide expanded LAN and WAN capabilities, such as Gigabit Ethernet and Ethernet switching.

Note EHWICs are supported on Cisco 1861-E, Cisco 1900 series (modular), Cisco 2900 series, and Cisco 3900 series routers.

Cisco interface cards are available in the following two form factors to provide greater modularity and functionality for users:

  • Single-wide interface cards (see Figure 1)
  • Double-wide interface cards (see Figure 2)

Single-wide interface cards can be installed in interface card slots on supported Cisco access routers, in 1- or 2-slot network modules to be installed in network module slots on supported Cisco access routers, and in interface card slots on Cisco 1800 (modular) series, Cisco 2800 series, and Cisco 3800 series routers. Figure 1 shows a sample single-wide interface card.

Figure 1 Sample Single-Wide Interface Card

 

Double-wide interface cards can only be installed in interface card slots on Cisco 1900 series, Cisco 2800 series, Cisco 2900 series, Cisco 3800 series, and Cisco 3900 series routers. Figure 2 shows a sample double-wide interface card.

Figure 2 Sample Double-Wide Interface Card

 

Cisco Access Routers and Cisco Interface Cards

The Cisco interface cards described in this document are supported on the following Cisco routers:

  • Cisco 1800 series (modular), including the Cisco 1841 routers (see Figure 3)
  • Cisco 1900 series (modular), including the Cisco 1941 routers (see Figure 4)
  • Cisco 2800 series, including the Cisco 2801, Cisco 2811, Cisco 2821, and Cisco 2851 routers (see Figure 5 and Figure 6)
  • Cisco 2900 series, including the Cisco 2901, Cisco 2911, Cisco 2921, and Cisco 2951 routers (see Figure 7, Figure 8, and Figure 9)
  • Cisco 3700 series, including the Cisco 3725 and Cisco 3745 routers (see Figure 10 and Figure 11)
  • Cisco 3800 series, including the Cisco 3825 and Cisco 3845 routers (see Figure 10)
  • Cisco 3900 series, including the Cisco 3925 and Cisco 3945 routers (see Figure 11)
  • Cisco MWR 1941-DC routers (see Figure 12)
  • Cisco ICS 7750 routers

For information on these Cisco routers, see the hardware documentation described in the “Related Documents” section.

Note Certain Cisco interface cards are also supported on the Cisco ICS 7750. See Table 4 for more information.

Interface Card Slot Locations and Numbering on Cisco Access Routers

Cisco IOS Software Releases and Cisco Interface Cards

Cisco interface cards are often supported on multiple Cisco IOS releases. Cisco IOS release information is documented in the product data sheet and in Feature Navigator II.

To determine which Cisco IOS releases support your particular router and combination of cards and modules, go to the Software Advisor at http://tools.cisco.com/Support/Fusion/.

You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear.

Cisco Network Modules Supporting Cisco Interface Cards

Some Cisco network modules have interface card slots to allow installation of Cisco interface cards. These network modules have either one or two interface card slots, supporting either voice or data interface cards. See Figure 13 and Figure 14 for sample 1-slot and 2-slot network modules.

Note Some combination voice/data interface cards are supported on 1- or 2-slot network modules. However, interface card functionality is limited to either voice or data applications. See Table 1 for more information.

For more information about Cisco network modules, see Cisco Network Modules Hardware Installation Guide.

Cabling for Cisco Interface Cards

The cables required to connect the interface card to the network differ according to interface and connector type. See Table 2 for more information.

Note Cabling for 1- or 2-slot network modules is determined by the installed interface cards.

Note For network-end connectors and pinout specifications of the cables connecting the voice cards, see Cisco Modular Access Router Specifications.
