Feature Benefit
Support for Cisco IOS
Software Release 12.3T
feature sets
• The Cisco 2800 helps enable end-to-end solutions with full support for the latest Cisco IOS Software-
based QoS, bandwidth management, and security features.
• Common feature and command set structure across the Cisco 1700, 1800, 2600, 2800, 3700 and 3800
series routers simplifies feature set selection, deployment, management, and training.
Optional integrated power
supply for distribution of
Power over Ethernet (PoE)
• An optional upgrade to the internal power supply provides in-line power (802.3af-compliant Power-over-
Ethernet [PoE] and Cisco standard inline power) to optional integrated switch modules.
Optional integrated universal
DC power supply
• On the Cisco 2811, 2821, and 2851 routers an optional DC power supply is available that extends
possible deployments environments such as central offices and industrial environments (Note: not
available on the Cisco 2801).
Integrated redundant-power-
supply (RPS) connector
• On the Cisco 2811, 2821, and 2851 there is a built in external power-supply connector that eases the
addition of external redundant power supply that can be shared with other Cisco products to decrease
network downtime by protecting the network components from downtime due to power failures.
Modularity—Features and Benefits
The Cisco 2800 Series provides significantly enhanced modular capabilities (refer to Table 2) while maintaining investment protection for
customers. The modular architecture has been redesigned to support increasing bandwidth requirements, time-division multiplexing (TDM)
interconnections, and fully integrated power distribution to modules supporting 802.3af PoE or Cisco in-line power, while still supporting most
existing modules. With more than 90 modules shared with other Cisco routers such as the Cisco 1700, 1800, 2600, 3700, and 3800 series,
interfaces for the Cisco 2800 Series can easily be interchanged with other Cisco routers to provide maximum investment protection in the case
of network upgrades. In addition, taking advantage of common interface cards across a network greatly reduces the complexity of managing
inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes.
Table 2. Modularity—Features and Benefits
Feature Benefit
Enhanced network-module (NME)
slots
• The NME slots support existing network modules (Note: NM and NME support on Cisco 2811,
2821, and 2851 only)
• NME Slots offer high data throughput capability (up to 1.6Gbps) and support for Power over
Ethernet (POE).
• NME slots are highly flexible with future support for extended NMEs (NME-X on Cisco 2821
and 2851 only) and enhanced double-wide NMEs (NME-XDs) (Note: Cisco 2851 only).
High-performance WIC (HWIC)
slots with enhanced functionality
• Four integrated HWIC slots on Cisco 2811, 2821, and 2851 and two integrated HWIC slots on
Cisco 2801 allow for more flexible and dense configurations.
• HWICs slots can also support WICs, VICs, and VWICs
• HWIC slots offer high data throughput capability (up to 400 Mbps half duplex or 800 Mbps
aggregate throughput) and Power over Ethernet (POE) support.
• A flexible form factor supports up to two double-wide HWIC (HWIC-D) modules.
