Utilizing a single Intel Prestonia Xeon 2.4GHz processor, the Cisco MCS 7835I-2400 is a robust highly available server platform designed to support today's IP Communications applications. The MCS 7835I-2400 supports up to 4GB of Double Data Rate (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.The MCS 7835I-2400 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 only operating them when required and at a speed based upon the cooling requirements.The MCS 7835I-2400 supports IBM's new NetBAY Advanced Connectivity Technology products that helps reduce KVM costs by letting administrators' chain systems together with Cat5 cable. In addition to reducing overall costs, Advanced Connectivity Technology reduces bulk cable clutter, making servers more accessible and serviceable in the rack.The MCS 7835I-2400 is equipped with Light Path Diagnostics. Light Path Diagnostics provides a central information LED panel (visible without removing the cover) and individual LED lights throughout the system on items like memory DIMMs, PCI slots, power supplies and CPU's. IT can then quickly view system status and in the case of a problem, service personnel can pinpoint the specific failing component, helping reducing downtime and service costs. This can provide increased availability, since nontechnical personnel can now 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 will help identify and locate problems with some server components. By following the path of lights, you can quickly identify the type of system error that occurred. The MCS 7835I-2400 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.The MCS 7835I-2400 supports Enhanced Predictive Failure Analysis (PFA) on hot swap fans, power supplies, processors and memory and voltage regulator modules. Through diagnostics the MCS 7835I-2400 is able to anticipate failures in these devices and generate an alert, which can allow IT 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.The MCS 7835I-2400 is equipped with Chipkill memory as part of its architecture. Chipkill Memory which protects, at the motherboard level, against 1, 2, 3 and 4 bit memory errors - protecting against 99% of memory failures. This, coupled with enhanced predictive failure analysis helps administrators keep planned and unplanned downtime to a minimum.
