Cisco 4451-X Integrated Services Router
Product Overview

Benefits |
Description |
Services integration |
• The Cisco 4451-X Router offers service integration with voice, video, security, data, and embedded services.
• The Cisco 4451-X provides the highest performance among the routers in the Cisco ISR portfolio, enabling you to maximize services integration and reducing overall capital expenditures (CapEx) and OpEx.
|
Services on demand |
• The Cisco 4451-X industry-first internal services plane allows for remote installation of application-aware services without compromise. Applications run and are managed identically to their counterparts in dedicated appliances.
• A single Cisco IOSXE Software Universal image is installed on each Cisco ISR. The Universal image contains all of the Cisco IOS XE Software technology sets, which you can activate with a software license. With the Universal image your business can quickly deploy advanced features without downloading a new Cisco IOS XE Software image.
• The Cisco Unified Computing System™ (Cisco UCS®) E-Series modules allow you to reduce CapEx and deploy a variety of application services in an integrated general-purpose server.
|
High performance with integrated services |
• The Cisco 4451-X enables deployment in high-speed WAN environments with concurrent services enabled up to 2Gbps.
• The backplane architecture enables high-bandwidth module-to-module communication up to 10 Gbps without compromising router performance.
|
Network agility |
• The Cisco 4451-X gives you the performance and services needed to accommodate the changes in the business environment brought about by the migration to cloud-based services.
• Performance-on-demand licensing increases the router capacity without any hardware upgrades.
• Dual integrated power supplies provide power redundancy and industry-leading power efficiency.
• Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.
|
Investment protection |
• The Cisco 4451-X maximizes investment protection by supporting a rich set of Cisco IOS XE Software features delivered in a single, universal image.
• The Cisco 4451-X offers extensive growth possibilities as your network expands:
• The performance-on-demand licensing enables flexibility for future upgrades.
• Module density provides flexibility to add services as your business needs expand.

Architectural Features and Benefits of Cisco 4451-X
Architectural Features |
Benefits |
Modular platform |
• The Cisco 4451-X is a modular platform with several types of module slots to add connectivity and services for varied branch-office network requirements.
• The routers offer a breadth of LAN and WAN connectivity options through modules to accommodate field upgrades to future technologies without requiring platform replacement.
|
Processors |
• The Cisco 4451-X is powered by high-performance multicore processors that can support the growing demands of high-speed WAN connections to the branch office while also running multiple concurrent services.
• The Cisco 4451-X data plane uses an emulated Quantum Flow Processor (QFP) that delivers application-specific integrated circuit (ASIC)-like performance that does not degrade as services are added.
|
Embedded IP Security (IP sec) VPN hardware acceleration |
• Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined with an optional Cisco IOS XE Software Security license, enables WAN link security and VPN services. |
Integrated Gigabit Ethernet ports |
• The Cisco 4451-X provides four 10/100/1000 Ethernet ports for WAN or LAN.
• All four of the 10/100/1000 Ethernet ports can support Small Form-Factor Pluggable (SFP)-based connectivity in addition to RJ-45 connections, enabling fiber or copper connectivity.
• You also have the option of enabling PoE on 2 out of the 4 ports.
• An additional dedicated Gigabit Ethernet port is provided for device management.
|
USB-based console access |
• A mini type-B USB console port supports management connectivity when traditional serial ports are not available.
• Traditional console and auxiliary ports are also available.
|
Optional integrated power supply for distribution of PoE |
• An optional upgrade to the internal power supply provides inline power (802.3af-compliant PoE or802.3at-compliant PoE+) to optional integrated switch modules.
• Redundant PoE conversion modules provide an additional layer of fault tolerance.
• Optional PoE on two front Gigabit Ethernet interfaces provides power to external devices such as fourth-generation (4G) routers.
|
Optional integrated redundant power supply (RPS) and PoE boost |
• Power redundancy is available by installing an optional integrated RPS, thereby decreasing network downtime and protecting the network from power failures.
• Optional PoE boost mode increases total PoE capacity to 1000W.
