It enables more effective, more secure, more personal communications that directly affect both sales and profitability. It brings people together by enabling a new way of communicating-where your business moves with you, security is everywhere, and information is always available...whenever and wherever it is needed. Cisco Unified Communications is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.
Product Overview
The Cisco® MCS 7835-H2 is a high-availability server platform for Cisco Unified Communications solutions. An integral part of a complete, scalable architecture for a new generation of high-quality IP voice solutions that run on enterprise data networks, the Cisco MCS 7835-H2 delivers the high performance and availability demanded by today's enterprise networks and represents an innovative solution that is easy to deploy and highly cost-effective. At only 2 rack units (2RUs) high, the Cisco MCS 7835-H2 offers tremendous power in a low-profile chassis that minimizes rack space. The Cisco MCS 7835-H2 runs a variety of Cisco Unified Communications applications, such as Cisco Unified Communications Manager (formerly known as Cisco Unified CallManager).

Key Features and Benefits
Performance
The Cisco MCS 7835-H2 is a robust, highly available server platform designed to support today's Cisco Unified Communications applications. It uses a Smart Array P400 Controller with a 256-MB cache to provide onboard RAID support. The Cisco MCS 7835-H2 occupies only 2RUs of space while providing the features most requested in a high-availability server platform. At product introduction the Cisco MCS 7835-H2 will ship with an Intel Xeon 2.33-GHz processor.
High Availability
High availability on the Cisco MCS 7835-H2 is achieved through the following mechanisms:
• Redundant hot-swap 800W power supplies
• Redundant hot-swap fans
• Hot-swap SAS hard drives configured using RAID 1
Serviceability
System Health LEDs
The Cisco MCS 7835-H2 provides system health LEDs and unit identification lights on the front and back of the server to make pinpointing system problems easier than ever. When an internal component fails, this indication is made on an internal component LED (amber) and on the front panel of the Cisco MCS 7835-H2. If the item is serviceable without removing the server hood, as in the case of a redundant power supply, the external health LED illuminates. 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 LEDs are green. If a failure has occurred but a redundant feature has enabled the system to continue running, the LED is amber. If the failure is critical and has caused the system to shut down, the LED is red.
Integrated Lights Out 2
The iLO 2 Standard and Advanced is included on this server. Combining essential management functions and diagnostics with basic lights-out functions as standard components of the server, iLO 2 is available at no charge. The iLO 2 standard provides fundamental server control and monitoring by integrating essential lights-out technology directly into the Cisco MCS 7835-H2 server architecture.
• Essential lights-out features include remote power control, text-based console, logs, status, and alert forwarding.
• The easy-to-use, dedicated lights-out LAN port is accessible through a browser interface.
• The iLO 2 standard saves a valuable PCI slot for additional functions and reduces installation and setup time.
• The iLO 2 standard eliminates the need for an external power adapter or any other internal or external cables.
• The iLO 2 standard provides a rich suite of security features, including Secure Sockets Layer (SSL).
• The iLO 2 standard provides a scalable solution by allowing group administration of iLO processors.
Redundant ROM
In the Cisco MCS 7835-H2, the ROM is divided into two logical sections. When the system boots, the primary ROM section is executed and used in server operation. During a ROM flash, the backup section is flashed. When the flash is fully completed, the backup section becomes the primary. If under rare conditions the flash does not complete safely, potentially because of power interruption, the backup is available to boot the system. In the situation where both ROM images are valid, the user can select which image to use at boot time.
DAT Tape Support
The Cisco MCS 7835-H2 can support an optional 36-/72-GB USB external Digital Audio Tape (DAT) drive or an optional USB rack-mount DAT drive. This tape drive connects through one of the 4 USB 2.0 ports provided by the Cisco MCS-7825-H2 server. The external DAT drive is orderable using part number DAT-USB-EXT-72=, and the rack-mounted 36-/72-GB DAT drive is orderable using part number DAT-USB-RM-72=.
