HP Integrated Lights-Out 2 User Guide

System Information SummaryThe System Information Summary tab displays the state of monitored host platform subsystems status at aglance, summarizing the condition of the monitored subsystems, including overall status and redundancy(ability to handle a failure). The subsystems can include fans, temperature sensors, power supplies, andvoltage regulator modules.• The Fans tab displays the state of the replaceable fans within the server chassis. This data includesthe area that is cooled by each fan and the current fan speeds.• The Temperatures tab displays the condition monitored at temperature sensors at various locations inthe server chassis and processor temperature. The temperature is monitored to maintain the locationtemperature below the caution threshold. If the temperature exceeds the caution threshold, the fanspeed is increased to maximum.• The VRMs tab displays VRM status. A VRM is required for each processor in the system. The VRMadjusts the power to meet the power requirements of the processor supported. A failed VRM preventsthe processor from being supported and should be replaced.• Power Supplies displays the presence and condition of installed power supplies.• OK indicates that the power supply is installed and operational.• Unpowered indicates that the power supply is installed, but not operational. Verify that thepower cord is connected.• Not present indicates that the power supply is not installed. Power is not redundant in thiscondition.• Failed indicates that the power supply should be replaced.FansiLO 2, in conjunction with additional hardware, controls the operation and speed of the fans. Fansprovide essential cooling of components to ensure reliability and correct operation. Fan location,placement, design and speed control take into account various temperatures monitored throughout thesystem to provide appropriate cooling with minimal noise levels.Fan operation policies might differ from server to server based on fan configuration and coolingdemands. Fan control takes into account the internal temperature of the system, increasing the fan speedto provide more cooling, and decreasing the fan speed if cooling is sufficient.
