Hardware Features

Note Throughout the remainder of the publication, one model number will be used in text

references. For example, references to the model 2501 router will apply to both the

Cisco 2501 and CPA2501 routers.

Hardware Features

In addition to the interfaces listed in Table 1-1, the routers include the following hardware

features:

•Dynamic random-access memory (DRAM) for main memory and shared memory

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

•Flash memory for running the Cisco IOS software

•EIA/TIA-232 console port for local system access using a console terminal

•EIA/TIA-232 auxiliary port for remote system access using a modem

Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232

and RS-449 before their acceptance as standards by the Electronic Industries Association

(EIA) and Telecommunications Industry Association (TIA).
