Components and Expansion Modules for Cisco 2000/3000 Modular Routers

All Cisco 2000/3000 modular routers can be fitted with a variety of expansion cards - NM type, WIC type, AIM, and PVDM. However, not all modules and components work in all routers, and its important to know what cards and modules work with which routers, as well as what specific IOS is required. In general, many of the newer and more sophisticated expansion modules will only be compatible with the newer lines of routers. However, incompatibility of expansion modules with routers occurs extensively, by design; Cisco specifically designs certain WIC and NM modules to work ONLY with specific lines of routers, and they WILL NOT WORK in others. So do your homework!

The lines of routers supporting NM, WIC, AIM, and PVDM expansion modules are the Cisco 1700, 1800, 2600 / 2600XM, 2800, 2900, 3600, 3700, 3800, and 3900.

The general types of expansion modules and components, aside from the standard components of each router type, is reviewed below.

WIC/VIC/VWIC/HWIC Modules

WIC-Type "wide area interface cards" (including WIC, VWIC, VIC, and HWIC), are small, single-purpose trunk and ethernet cards that fit into WIC slots either in the actual router chassis or into a WIC slot on an NM card. Some examples of WIC cards are the WIC-1DSU-T1 (T1 interface with integrated DSU), VIC-2FXS (voice interface cards supporting 2 FXS connections), HWIC-4ESW (high speed WIC card with 4 ethernet ports), and VWIC2-2MFT-T1/E1 (voice WIC trunk card, version 2, supporting 2 T1/E1 voice PRI trunk lines). It is critically important to confirm compatibility of a card with a router. For example, WIC-4ESW cards only work in small office routers, like the 1700 series. A list of the more common WIC type cards is provided below, and you can Use this link to Cisco for a comprehensive compatibility guide for WIC type cards with most current and legacy 2000/3000 routers.

This etherswitch card requires the double wide NM slot to provide an integrated switching function to a router.

Network Modules (NM, NME, NMD)

Many modular routers have at least 1 network module slot (NM slot), or the enhanced, larger version - NME or NMD. NMs are much larger slots for generally more sophisticated expansion modules. There is, for example, an NM-CUE (VOIP Unity Express) module that puts an entire Unity voicemail system on a router, as well as NM-1GE to add a gigabit GBIC ethernet, NM-2FE2W (adds two fast ethernet ports), and NM-HDV2-2T1/E1 (PVDM2 voice DSP carrier card with 2 T1/E1 voice trunk ports), among many. Again, matching the card to the hardware and IOS is critical; the NM-2FE2W for example does NOT work in most of the routers you'd want to use it in! An NM switch-switch type card for the ISR series - single and double width.

Physically larger NM type cards include the NME and NMD types, and these are only useable in routers physically supporting them. Click here for Cisco's list of NM Type cards that are compatible with both current and legacy Cisco routers.

AIM, PVDM, and Other Modules

There are a variety of other expansion modules for the 2000/3000 series. PVDM voice DSP modules (PVDM, PVDM-256K, PVDM2, and PVDM3) can be installed either on a router mainboard or NM-HDV2 expansion module for VOIP processing. AIM 'advanced integration modules' are daughter cards that attach directly to a router mainboard to provide enhanced SSL encryption, voicemail/IVR services, or VOIP DSPs.

In addition, there are a variety of other components and accessories, including mounting brackets, cables, DRAM and Flash modules, specialty covers and dividers, external flash modules (compact flash or PCMCIA), and a variety of specialty components sometimes needed for upgrades or replacement. Some of them may even be hard to identify, but if you contact us, we're normally able to tell you what it is and whether it's available.
