A06-0479 -2- • Voltages • Power supply status • Memory status • Fan status • HDD status • Error and status log You can receive the status and you can control all blade servers within the BladeCenter. You can also shut down and restart any blade server from anywhere on the network to help save time and costs associated with travel to the actual installation. These manageability functions are provided through a self-contained Web page, creating an easy, familiar way for administrators to monitor, control and maintain highly available BladeCenter installations. The management module communicates to the JS20 blades through a serial-over-LAN interface. Power management in the NEBS operating environment The 8842-RTx model is designed with a power management capability capable of providing the maximum uptime possible for your systems. In short term extended thermal conditions, the JS20 RTx model automatically reduces the frequency of the processor to maintain acceptable thermal levels rather than shut down completely or fail. The processor frequency will then automatically cycle backup as thermal conditions improve. Power management is invoked only when the blade is housed in a BladeCenter T chassis and only under the thermal conditions described as short term in the high end of the NEBS extended temperature range (41° to 55°C). The BladeCenter management module (MM) is notified when power management starts and again when it stops. Appropriate entries are then made in the MM Event Log. Applications could be sensitive to processor frequency changes. For instance, frequency reductions could potentially impact benchmarking or applications/tools that depend on execution times for accounting, CPU utilization or profiling. It is recommended that you contact your individual application vendors to determine if there are any possible impacts and to weigh the potential benefits and risks of 8842-RTx power management in the short term extended thermal NEBS environment before installing the system.

Note: Short term refers to a period of not more than 96 consecutive hours and a total of not more than 15 days in one year. (This refers to a total of 360 hours in any given year, but no more than 15 occurrences during that one-year period.)
