Product Overview

The Cisco MCS 7825-H2 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. A solution that is easy to deploy and highly cost-effective, this powerful platform 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 server 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 memory, error correction code (ECC), double data rate 2 (DDR2), and synchronous dynamic RAM (SDRAM) standard; 8 GB maximum

• Two integrated 10/100/1000BASE-T 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

• 450W autoranging, Power Factor Correction (PFC) power supply

• 1-rack-unit (1RU) (1.75 in./4.5 cm high) form factor

• Integrated Lights Out (ILO) remote management
