Cisco® Integrated Services Routers (ISRs) are built on 30 years of our innovation and product leadership.
The Cisco 4451-X Integrated Services Router revolutionizes the delivery of application-aware services in a branch-office environment. This new member of the Cisco ISR Family provides extensive Layer 7 services hosted internally to the branch office while maximizing operating expenses (OpEx) savings.
You can order the platform as a base system or as a bundled system for security, unified communications, or application services. This ordering guide focuses on base system configurations and options, but most of the elements are applicable to bundle ordering as well. For a detailed list of advanced technology bundles, please refer to section 4 of this ordering guide.
1.1 Ordering the Cisco 4451-X Integrated Services Router
The Cisco 4451-X offers the highest performance among the ISR portfolio.
Table 1 lists the part number for the Cisco 4451-X platform.

You can order each Cisco 4451-X platform with dual power supplies that you can configure for power-supply redundancy.
You can order the power supplies listed in Table 2 with the system or as spares.
Table 2. Cisco 4451-X Power Supply Options (Offered with the System and as Spares)

The Cisco 4451-X ships with a default memory of 2-GB DRAM for data plane and 4-GB DRAM for the control plane in addition to 8GB of flash memory. The 4-GB DRAM configuration for the control plane is derived by the installation of two symmetrical dual in-line memory modules (DIMMs) of 2 GB in each of the memory slots of the Cisco 4451-X platform. When upgrading memory to higher densities, both memory slots must be populated with DIMMs of symmetrical type and density for high system performance. The Cisco 4451-X does not support the use of different DRAM densities in the 2 available DIMM slots or the use of only 1slot. The memory type and part numbers are as listed in Table 3.

1.2 Ordering Optional Items for Cisco 4451-X Router
Each Cisco 4451-X ships with a default accessory kit consisting of:
• 19-inch rack-mount brackets
• Regulatory & Compliance Safety Information (RCSI) guide
The default accessory kit does not include any Category 5 RJ-45 Ethernet cables or cables for the router console or auxiliary port. You can order the console and auxiliary cables as an option during router configuration or as spares.
You can order the 23-inch rack-mount brackets, the blank faceplates for module slots, and slot dividers as spares (Table 6).
Opacity shields are not required for the Cisco 4451-X because the router ships with a solid cover and the router interior is not exposed. Table 6 lists the part numbers for cables, rack-mount brackets, blank faceplates, and storage drives.

2. Ordering Cisco IOS Software Images and Licenses
Cisco ISRs deliver innovative technologies running on the industry-leading Cisco IOS® Software.
The Cisco 4451-X ships with a universal Cisco IOS Software image that contains all the features available for use on the router. A specific feature set is activated by using technology package licenses such as Security, Unified Communications, and Application Experience.
The Cisco 4451-X supports two types of universal images:
• Universal images with universalk9 in the image name: This universal image offers all the Cisco IOS Software features, including strong payload cryptography features such as IP Security VPN (IPsec VPN) and Secure Unified Communications.
• Universal images with universalk9_npe in the image name: The strong control of encryption capabilities by Cisco Software Activation helps meet U.S. export control requirements for cryptography. However, some countries have import requirements that require that the platform not support any strong payload cryptography. To satisfy the import requirements of those countries, Cisco allows you to order the router with an "npe" universal image that does not support any strong payload encryption. The npe image does support security features such as zone-based firewall and intrusion prevention through the SECNPE-K9 license.
Table 7 lists part numbers for universal Cisco IOS Software images for the Cisco 4451-X.

By default, you need to select an IP Base license. You can order the routers from the factory with technology licenses preinstalled using the paper license part numbers (start with the keyword "SL"). Alternately, if you plan to deploy the advanced technology features later, you can order the required licenses as spares. You can order spares for technology licenses as paper licenses or e-delivery licenses (start with keyword "SL").
The part numbers are listed in Table 8.
Table 8. IP Base Licenses for Cisco 4451-X (Maps to Both Types of Universal Images)

The Cisco 4451-X also offers a wide variety of feature licenses for unified communications functions such as Cisco Unified Communications Manager Express (Unified CME), Survivable Remote Site Telephony (SRST), and Cisco Unified Border Element.You need these licenses in addition to the technology license for a given solution deployment.
3. Ordering Modules for Cisco 4451-X
For a complete list of supported and unsupported modules, please refer to the Cisco Relevant Modules and Interfaces document for each product family.
You can also order the Cisco 4451-X as prepackaged bundled systems for deploying advanced technologies such as security, unified communications, and application services in the branch office.
4.1 Security Bundles
Cisco router security bundles deliver security features such as Cisco IOS Software-based firewall, VPN, and infrastructure security services over numerous WAN access technologies, offering high levels of performance, scalability, and availability to meet today's growing business requirements. Table 13 lists the security bundle for the Cisco 4451-X Router that comes with the Security technology license activated and the advanced security features available for use. By default, this bundle ships with the universal Cisco IOS Software image that supports payload cryptography.
