The Cisco® Unified Communications system of voice and IP communications products and applications helps organizations communicate more effectively-by helping them streamline business processes, reach the right resource the first time, and increase profitability. The Cisco Unified Communications portfolio is an integral part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes that also includes network infrastructure, security, and network management products; wireless connectivity; and a lifecycle services approach-along with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.

Product Overview

The Cisco MCS 7825-I2 Unified CallManager Appliance is an integral part of a complete, scalable architecture for a new generation of high-quality IP communications solutions that operate on enterprise data networks. This powerful platform is a solution that is easy to deploy and highly cost-effective, and it delivers the high performance and availability that today's enterprise networks demand. The server appliance is preinstalled with an operating system and the Cisco Unified CallManager 5.1 application. It is fully operational upon startup, requiring entry of just a few configuration items such as IP address and domain. The appliance includes the following features and components:

• Intel dual-core, Pentium D, 2.8- or 3.4-GHz processor with an 800-MHz front side bus (FSB) and 4 MB of Layer 2 cache

• 2 GB of installed PC2-4200 error correction code (ECC) double data rate 2 (DDR2) synchronous dynamic RAM (SDRAM); 8 GB maximum

• Two integrated 10/100/1000T Gigabit Ethernet network-interface-card (NIC) ports

• Two 80-GB serial-advanced-technology-attachment (SATA) hard disk drives configured in Redundant Array of Independent Disks (RAID) level 1

• No floppy diskette drive installed

• Quick-deployment third-party rail kit

• 350W autoranging, Power Factor Correction (PFC) power supply

• One rack unit (1RU) (1.75 in./4.5 cm high) form factor, 22 in./56 cm deep
