Cisco, Network Equipment Resource: Who Is “The Frickin Awesome Router”?

The Cisco 4451-X Integrated Services Router (ISR) is a modular router with LAN and WAN connectivity and supports several interface modules, including Cisco Service Modules (SMs), or Enhanced Service Modules (SM-X), and Network Interface Modules (NIMs). The router has slots that support the interface modules and modular Solid State Drives (SSDs).

The Cisco ISR 4451-Xs target the following applications:

• Enterprise applications—Intended as the mid-size aggregation and gateway router typically residing in a regional or large branch office:

–WAN aggregation at Cisco Enterprise core

–Internet gateway

–Branch or regional office aggregation

–Remote access aggregation

• Service provider applications—Intended for high-end Enterprise Branch environments.:

–High-end customer premises equipment (CPE) for business-quality Internet access

–Service provider leased line aggregation

–Provider edge (PE) and high-end customer edge (CE) for Layer 2 VPN or Layer 3 VPN services

–Broadband aggregation—PPPoE/PPPoA aggregation and Service Selection Gateway (SSG)

–Low-end Ethernet aggregation

The Cisco ISR 4451-Xs provide the following capabilities:

•Two single-wide SM slots that may be combined into one double wide SM slot.

•Three single-wide NIM slots that may combined into one double wide (NIM1 and NIM2) and one single wide NIM slot (NIM3). The slots can also support a modular or optional SSD.

•NIM3 slot also functions as a special hard drive carrier slot.

•1 10/100/1000 RJ-45 Ethernet port for system managements (labeled "GE 0" with "MGMT" on the left of the connector)

•2 USB 2 Type A host ports

•1 USB mini-TypeB Console (placed next to the RJ45 Console port)

•1 RJ45 Console

•1 RJ45 AUX port with full modem control signals

•4 10/100/1000 RJ-45 Ethernet ports (labeled GE 0/0/0, 0/0/1, 0/0/2, and 0/0/3)

•4 100/1000 SFP Ethernet ports (labeled SFP 0/0/0, 0/0/1, 0/0/2, and 0/0/3)

•LEDs for Ethernet and console status

•LEDs for SATA hard disk drive activity and status (available on certain models)

•Two DDR3 240 pin Control Plane DIMM slots which can be replaced

•One DDR3 240 pin Data Plane DIMM slot which can be replaced
