Cisco Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks enabling easy collaboration every time from any workspace.
The Cisco MCS 7845-H2 Media Convergence Server is a high-availability server platform for Cisco Unified Communications Solutions. It is an integral part of a complete, scalable architecture for a new generation of high-quality IP voice solutions that run on enterprise data networks. It 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 7845-H2 packs tremendous power in a low-profile chassis that minimizes rack space.
The Cisco MCS 7845-H2 can run any of the following Cisco applications:
• Cisco Unified Application Environment
• Cisco Unified Communications Manager: Up to 7,500 Cisco Unified IP Phones per server
• Cisco Emergency Responder; Up to 30,000 Cisco Unified IP Phones per server
The Cisco MCS 7845-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 256-MB cache to provide onboard redundant Array of Independent Disks (RAID) support. The server occupies only 2RU of space while providing the features most requested in a high-availability server platform. At product introduction, the Cisco MCS 7845-H2 will ship with two Intel Xeon 2.33-GHz processors.
High availability on the Cisco MCS 7845-H2 is achieved through the following mechanisms:
• Redundant hot-swap power supplies
• Redundant hot-swap fans
• Hot-swap SAS hard drives configured using RAID 1
System Health LEDs
The Cisco MCS 7845-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 7845-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 Integrated Lights Out 2 (iLO 2) standard is included on the motherboard. Combining essential management functions and diagnostics with basic lights-out functions as standard components of the server, iLO 2 is available at no charge.
• iLO 2 provides fundamental server control and monitoring by integrating essential lights-out technology directly into the Cisco MCS 7845-H2 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.
• iLO 2 saves a valuable Peripheral Component Interconnect (PCI) slot for additional functions and reduces installation and setup time.
• iLO 2 eliminates the need for an external power adapter or any other internal or external cables.
• iLO 2 provides a rich suite of security features, including Secure Sockets Layer (SSL).
• iLO 2 provides a scalable solution by allowing group administration of iLO 2 processors.
DAT Tape Support
The Cisco MCS 7845-H2 can support an optional 36/72-GB universal-serial-bus (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-7845-H2. 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=.
