In addition to the interfaces listed in Table 1-1, Cisco 2600 series routers include the following hardware features:

•Dynamic random-access memory (DRAM) for main memory and shared memory (Cisco 261x and Cisco 262x routers)

•Synchronous dynamic random-access memory (SDRAM) for main memory and shared memory (Cisco 26xxXM, Cisco 265x, and Cisco 2691 routers)

•Nonvolatile random-access memory (NVRAM) for storing configuration information

•Flash memory—Stores the operating system software image. In Cisco 2691 routers, flash memory is a CompactFlash memory card. In all other Cisco 2600 series routers, flash memory is a single inline memory module (SIMM).

•EIA/TIA-232 (RJ-45) console port for local system access by using a console terminal

•EIA/TIA-232 (RJ-45) auxiliary port for remote system access or dial backup by using a modem Figure 1-1and Figure 1-2show examples of Cisco 2600 series routers.

Note Cisco 2600 series routers are either single rack-unit (1RU) or two rack-unit (2RU) high.

Note The number and type of interfaces vary, depending on the specific router.
