Hardware Supported
Cisco IOS Release 12.1(5)YC3 supports the following Cisco 800 series routers:
•Cisco 811 and Cisco 813
•Cisco 827 and Cisco 827-4V
For detailed descriptions of new hardware features, see New and Changed Information.
Cisco 811 and 813 Routers
The Cisco 811 and 813 Routers provide the following key hardware features:
•Flash memory: Default is 8 MB and is expandable to 12 MB. Additional Flash memory is installed using Intel "Mini-Card" technology.
•Dynamic RAM: Default is 8 MB and is expandable to 16 MB, which must be obtained from Cisco Systems.
•The central processing unit is a 33 MHz MPC 850 processor.
•Routers mounted on a wall.
Table 2 lists the supported interfaces for the Cisco 811 and 813 routers.

Cisco 827 and Cisco 827-4V Routers
The Cisco 827 and Cisco 827-4V Routers provide the following key hardware features:
•The routers provide connection to an ADSL network or telephones and fax machines through an ADSL port.
•Flash memory: Default is 12 MB and is expandable to 20 MB. If 12 MB of Flash is installed, 8 MB is used for the Cisco IOS images and 4 MB hosts the ROMMON and NVRAM. Additional memory can be added using Flash cards.
•Cisco 827 Router Dynamic RAM: Default is 16 MB of DRAM and is expandable to 32 MB.
•Cisco 827-4V Router Dynamic RAM: Default is 24 MB and is expandable to 32 MB. The Cisco 827-4V Router also contains an 8-MB DIMM card.
•The central processing unit is a 50 MHz MPC 855T RISC processor.
•Color-coded ports and cable reduce the chance of cabling errors.
•Routers can be stacked or mounted on a wall.
•The routers provide locking power connectors and a Kensington-compatible locking slot.

Determining Your Software Release
To determine the version of Cisco IOS software running on your Cisco 800 series router, log in to the router and enter the show version EXEC command:
Cisco Internetwork Operating System Software
IOS (tm) 800 Software (C800-Y6-MW), Version 12.1(5)YC2, RELEASE SOFTWARE
Upgrading to a New Software Release
For general information about upgrading to a new software release, see Cisco IOS Upgrade Ordering Instructions located at:
http://www.cisco.com/warp/public/cc/cisco/mkt/ios/prodlit/957_pp.htm
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release 12.1(5)YC3 supports the same feature sets as Releases 12.1 and 12.1 T, but Release 12.1(5)YC3 can include new features supported by the Cisco 800 Series Routers. Table 4 lists the feature sets supported by the Cisco 800 Series Routers.
