DellPowerEdge T310 Technical Guide 195 Power, Thermal, Acoustic5.1 Power SuppliesThe Dell™ PowerEdge™ T310 system includes a single non-redundant 375W power supply or anoptional redundant 400W power supply.The power supply subsystem provides power to the planar, four internal hard drive bays (cabled harddrive chassis), the hard drive backplane (hot-plug hard drive chassis), and the two 5.25‖ drive bays.Power is soft-switched, allowing power cycling using a switch on the front of the system enclosure orthrough software control (through server management functions). The power system is compatiblewith industry standards, such as ACPI and Server 2000.For a redundant power supply configuration, the second power supply provides hot-pluggable powerredundancy. In redundant mode, the system distributes the power load across both power supplies tomaximize efficiency. When a power supply is removed with the system powered on, the full powerload is picked up by the remaining power supply.If using only one hot-plug power supply, the power supply is installed in the PS1 location and a blankmodule (metal cover) is installed in the PS2 location for factory consistency. Electrically, the systemcan operate with a single power supply in either bay. The power supply has automatic input voltagedetection. An auxiliary power-out receptacle is not provided on this unit.The type of power supply can be selected when ordering a system. After purchase, upgrading from anon-redundant to a redundant configuration, or vice-versa, is not possible.5.2 Power Supply SpecificationsTable 5 shows the power supply specifications.Table 5.
