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-H1 Unified CallManager Appliance (MCS 7825-H1) 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 turnkey 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 5.0 application. 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:
• Intel Pentium 4 3.4GHz processor, a 800MHz front side bus (FSB), and 1MB of Layer 2 cache
• PC3200 double-data-rate-1 (DDR1) 400MHz RAM
• Two gigabit network interface cards (NICs)
• Two 80-GB serial advanced technology attachment (ATA) hard-disk drives configured in Redundant Array of Independent Disks (RAID) 1
• Quick-deployment third-party rail kit
• 350 W power-factor-correction (PFC) power supply
• 1 RU (1.75-in.) form factor
• Integrated Lights Out (ILO) remote management
The Cisco MCS 7825-H1 Unified CallManager Appliance supports up to 1000 IP phones per server and 4000 IP phones per cluster.
KEY FEATURES AND BENEFITS
The Cisco MCS 7825-H1 Unified CallManager Appliance is a robust, highly available server platform designed to support Cisco Unified CallManager 5.0 using a single Intel Pentium 4 3.4 GHz processor with an 800 MHz FSB.
The Cisco MCS 7825-H1 Unified CallManager Appliance provides system-health LEDs and unit-identification lights on the front and back of the server to ease the identification of system issues. When an internal component fails, this indication is made on an internal-component LED (amber) and on the front panel of the Cisco MCS 7825-H1 Unified CallManager Appliance. If the item is serviceable by removing the hood, as in the case of a fan failure, the internal-health LED illuminates. If no failures have occurred, the system-health LED is green. If the failure is critical and has caused the system to shut down, the LED is red.
In the Cisco MCS 7825-H1 Unified CallManager Appliance, the ROM is divided into two logical parts. When the system boots, the primary ROM side is executed and used in server operation. During a ROM flash, the backup side is flashed. When the flash is fully completed, the backup side becomes the primary. If under rare conditions the flash does not complete safely, potentially because of a power interruption, the backup is available to boot the system. In the situation where both images are valid, the user can select which image to use at boot time.
Serviceable SATA Disk Drives
The Cisco MCS 7825-H1 Unified CallManager Appliance is configured with two 80-GB serial advanced technology attachment (SATA) "cold-pluggable" disk drives configured in a RAID 1 mirror set. The appliance continues to operate if either of the two disk drives fails. The SATA disk drives are accessible to the end user through openings in the front bezel of the server. If a drive fails, the end user can schedule server downtime, power down the server, and replace the failed SATA drive by simply removing it (each drive is equipped with a front latch that positively mates the drive to the server) and replacing it with an unconfigured spare drive. After restarting the server, the RAID 1 firmware initiates a re-mirroring of the new drive to help ensure that drive redundancy on the Cisco MCS 7825-H1 Unified CallManager Appliance is maintained. The serial-drive technology introduced in the Cisco MCS 7825-H1 Unified CallManager Appliance provides a highly reliable, high-performance, cost-effective solution.
Table 1 gives specifications of the Cisco MCS 7825-H1 Unified CallManager Appliance.

IDENTIFYING SERVER CPU SPEED
As the Cisco MCS 7825-H1 matures, the processor speeds will be changed as Intel retires slower processors and replaces them with faster processors. Table 4 provides the Cisco manufacturing part number that is shown on the chassis to help identify any processor speed of any individual server.
