A redundant power configuration enables a fully-configured system to continue running even if one of the power supply module fails. WARNING!To reduce the risk of personal injury or damage to the equipment, the installation of power supply modules should be referred to individuals who are qualified to service server systems and are trained to deal with equipment capable of generating hazardous energy levels. To reduce the risk of personal injury from hot surfaces, observe the thermal labels on each power supply modules. You can also consider wearing protective gloves. To reduce the risk of personal injury from electric shock hazards, do not open the power supply module. There are no serviceable parts inside the module. Electrostatic discharge can damage electronic components. Make sure that you are properly grounded before handling a power supply module. 67 To install a hot-swap power supply module: 1 Detach the cover from the chassis.

In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance. BIOS setup loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM which allows configuration data to be retained when power is turned off. Before you run the PhoenixBIOS Setup Utility, make sure that you have saved all open files. The system reboots immediately after you close the Setup.
