The Cisco® Unified Communications system of voice and IP communications products and applications enables organizations to communicate more effectively-enabling them to streamline business processes, reach the right resource the first time and impact the top and bottom line. The Cisco Unified Communications portfolio is an integral part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes which 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.
The Cisco Media Convergence Server 7825-I1 Unified CallManager Appliance (MCS-7825-I1) is an entry-level appliance for Cisco Unified CallManager 5.0. It 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. It delivers the high performance and availability that today's enterprise networks demand, and it provides a turnkey solution that is easy to deploy and highly cost-effective. The server appliance is preinstalled with an operating system and Cisco Unified CallManager 5.0 software. The server appliance is fully operational upon startup, requiring entry of just a few configuration items such as IP address and domain. The Cisco MCS 7825-H1 Unified CallManager Appliance includes the following features and components (Figure 1):
• Intel Pentium 4 3.4GHz processor, an 800MHz front side bus (FSB), and 1MB of Layer 2 cache
The Cisco MCS 7825-I1 Unified CallManager Appliance supports Cisco Unified CallManager 5.0 with up to 1000 IP phones per server and 4000 IP phones per cluster.
PRIMARY FEATURES AND BENEFITS
The Cisco MCS 7825-I1 Unified CallManager Appliance is a robust, highly available server platform designed to support today's IP communications applications. It uses a single Intel Pentium 4 3.4 GHz processor with an 800 MHz FSB.
The Cisco MCS 7825-I1 Unified CallManager Appliance supports up to 4GB of DDR memory. The increased processor performance coupled with DDR memory allows customers to retrieve and process information faster and more efficiently. DDR memory executes twice the number of operations per cycle than traditional SDRAM memory, effectively doubling the data exchange rate between memory and processors.
Variable-Speed Fan Support
The Cisco MCS 7825-I1 Unified CallManager Appliance includes variable-speed fans to reduce operating noise. Through the use of temperature sensors within the server, the speed of the fans is adjusted to maintain the proper cooling. This reduces the noise generated by the fans by operating them only when required and at a speed based upon the cooling requirements.
SATA and Integrated RAID
The Cisco MCS 7825-I1 Unified CallManager Appliance supports enhanced serviceability through integrated RAID level 1 and front-accessible, simple-swap SATA hard-disk drives. If a hard drive fails, user data is preserved on the mirrored drive, and system administrators can easily replace the failing drive without removing the server from the rack. This reduces downtime and provides data reliability in a compact, highly cost-effective server.
System Error LEDs
The Cisco MCS 7825-I1 Unified CallManager Appliance provides a system error LED and system locator LED on the front of the server to make pinpointing system issues easier than ever. When a system error occurs, this indication is made on the front panel of the Cisco MCS 7825-I1 Unified CallManager Appliance. If no failures have occurred, the system error LED is not lit.
Table 1 gives product specifications of the Cisco MCS 7825-I1 Unified CallManager Appliance.
You may order the appliance in one of two ways. You can enter CALLMANAGER-5.0 into the Dynamic Configuration Tool on Cisco.com, and you will view a list of Cisco Unified CallManager appliances and their associated licenses. You may also order the components individually using the following product IDs:

IDENTIFYING SERVER CPU SPEED
As the Cisco MCS 7825-I1 Unified CallManager Appliance matures and as Intel retires slower processors and replaces them with faster processors, the processor speeds will be changed. Table 4 provides the Cisco manufacturing part number that is shown on the chassis to help identify any processor speed of any individual Cisco Unified CallManager Appliance.
