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 7835-I1 Unified CallManager Appliance (MCS 7835-I1) is a high-availability server platform for Cisco Unified CallManager 5.0 and an integral part of a complete, scalable architecture for a new generation of high-quality IP Communications solutions for enterprise data networks. Delivering the high performance and availability that today's enterprise networks demand, the solution is easy to deploy and highly cost-effective. The server appliance is preinstalled with an operating system and Cisco Unified CallManager 5.0. It is fully operational upon startup, requiring entry of just a few configuration items such as IP address and domain. At just 2 rack units (2RU) high, the Cisco MCS 7835-I1 Unified CallManager Appliance packs tremendous power in a low-profile chassis that minimizes rack space. It can support up to 2500 IP phones per server and 10,000 IP phones per cluster, and includes the following features and components:

• Intel Xeon 3.4-GHz or higher processor, an 800-MHz front side bus (FSB), and 2 MB of Layer 2 cache

• PC2-3200R 2-GB 400-MHz Double Data Rate 2 (DDR2) memory (must be installed in pairs)

• IBM ServeRAID 7k Redundant Array of Independent Disks (RAID) Controller with 256-MB memory and battery-backed caching

• Dual-port Gigabit Ethernet controller (embedded)

• Quick-deployment third-party rail kit

• Support for up to six 1-inch Ultra320 Small Computer System Interface (SCSI) hot-plug hard drives

• Hot-plug redundant power supplies

• Hot-plug redundant fans

• IBM LightPath Diagnostics to assist in identifying failed components

KEY FEATURES AND BENEFITS

Performance

The Cisco MCS 7835-I1 Unified CallManager Appliance is a robust, highly available server platform designed to support today's IP Communications applications. It includes such innovations as variable-speed fan support, NetBAY cabling support, and Light Path Diagnostics and Chipkill memory support. Occupying only 2RU of space, the Cisco MCS 7835-I1Unified CallManager Appliance provides the features most requested in a high-availability server platform. At product introduction, it includes an Intel Xeon 3.4-GHz processor, and the processor speed will be increased as Intel replaces the 3.4-GHz processor and introduces new processors.

High Availability

High availability on the Cisco MCS 7835-I1 Unified CallManager Appliance is achieved through the following mechanisms:

• Redundant hot-swap 625W power supplies

• Hot-swap SCSI hard drives configured using RAID 1

• Redundant hot-swap fans

Memory

The Cisco MCS 7835-I1 Unified CallManager Appliance supports up to 16 GB of DDR2 memory. The increased processor performance coupled with DDR2 memory allows for quick, efficient retrieval and processing of information. DDR memory executes twice the number of operations per cycle than traditional synchronous dynamic RAM (SDRAM) memory, effectively doubling the data exchange rate between memory and processors.

Variable-Speed Fan Support

The Cisco MCS 7835-I1 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, reducing the noise generated by the fans by operating them only when required and at a speed based upon the cooling requirements.

Advanced Connectivity Technology

The Cisco MCS 7835-I1 Unified CallManager Appliance supports IBM's new NetBAY Advanced Connectivity Technology products that help reduce Keyboard/Video/Mouse (KVM) costs by linking administrators' chain systems with Category 5 cable. In addition to reducing overall costs, Advanced Connectivity Technology reduces bulk cable clutter, making servers accessible and serviceable in the rack.

Serviceability

Light Path Diagnostics

The Cisco MCS 7835-I1 is equipped with Light Path Diagnostics, providing a central information LED panel (visible without removing the cover) and individual LED lights throughout the system on items such as memory dual in-line memory modules (DIMMs), peripheral-component-interconnect (PCI) slots, power supplies, and CPUs. It can quickly view system status, and service personnel can identify the specific failing component, helping reduce downtime and service costs. Thus the Cisco MCS 7835-I1 provides increased availability, because nontechnical personnel can report error conditions without removing the top cover and exposing vital components to further risk. If the system error LED on the front of the server is on, one or more LEDs inside the server or on the power supply will be on. These LEDs help identify and locate problems with some server components. By following the path of lights, users can quickly identify the type of system error that occurred. The Cisco MCS 7835-I1 is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the AC power source is good and the power supply can provide +5 VDC to the server.
Light Path Diagnostics provide indication of failures for the following conditions:

• One or both power supplies consuming power higher than maximum rating

• Power supply 1 failure

• Power supply 2 failure

• Error on voltage regulator module

• One or both processors failed

• Hardware configuration error

• Memory error

• Nonmaskable interrupt

• Error on the system board

• Service processor failure

• Error on adapter in PCI-X slots A, B, or C

• Hard disk error

• Fan failure or slow operation

• System temperature exceeded maximum rating

• Soft error

• RAID controller error

Enhanced Predictive Failure Analysis

The Cisco MCS 7835-I1 supports Enhanced Predictive Failure Analysis (PFA) on hot-swap fans, power supplies, processors, and memory and voltage regulator modules. Through diagnostics, the Cisco MCS 7835-I1 anticipates failures in these devices and generates an alert, allowing service personnel to quickly replace the components before a failure actually occurs. An example of PFA is its ability to monitor variations in electrical input/output to the power supplies and cooling fans.

DAT Support

The Cisco MCS 7835-I1 appliance can support an optional 36-/72-GB universal-serial-bus (USB) external Digital Audio Tape (DAT) drive (part number DAT-USB-EXT-72=) or an optional USB rack-mount DAT drive (part number DAT-USB-RM-72=). This tape drive connects through one of the 4 USB 2.0 ports provided by the Cisco MCS 7835-I1 appliance.
