Removable and Interchangeable Modules

Various optional modules can be installed in the router to provide specific capabilities. These modules can be installed either by inserting them into slots on the chassis, or by opening the chassis and plugging them into connectors inside the chassis.

•Flash memory and interface cards fit into slots on the chassis and can be installed or removed without opening the chassis.

There are three types of interface cards for the 1800 series modular routers:

–WAN interface cards (WICs)

–Voice WAN interface cards (VWICs—in data mode only on the Cisco 1841)

–High-speed WAN interface cards (HWICs)

•The following components plug into connectors inside the chassis and can be installed or removed only by opening the chassis:

–Advanced integration module (AIM)

–Synchronous dynamic RAM (SDRAM) small-outline dual in-line memory module (SODIMM) Table 2-2summarizes the optional modules:

Memory

Cisco 1800 series routers contain the following types of memory:

•SDRAM—Serves two functions. It stores the running configuration and routing tables, and it is used for packet buffering by the network interfaces. Cisco IOS software executes from SDRAM.

•Flash memory—Stores the operating system software image, configuration files, and log files. It is implemented in an external CompactFlash memory card.
