About this task

S001

DANGER

danger

Electrical current from power, telephone, and communication cables is hazardous.

To avoid a shock hazard:

• Connect all power cords to a properly wired and grounded electrical outlet/source.
• Connect any equipment that will be attached to this product to properly wired outlets/sources.
• When possible, use one hand only to connect or disconnect signal cables.
• Never turn on any equipment when there is evidence of fire, water, or structural damage.
• The device might have more than one power cord, to remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

S002

CAUTION

The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

S033

CAUTION

Hazardous energy present. Voltages with hazardous energy might cause heating when shorted with metal, which might result in spattered metal, burns, or both.

S035

CAUTION

Never remove the cover on a power supply or any part that has this label attached. Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

Attention

• Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

The following tips describe the type of power supply unit that the server supports and other information to be consider when installing a power supply unit:

• The standard shipping has only one power supply unit installed in the server. For redundancy and hot-swap support, installing an additional power supply unit is a must. Certain customized models might be shipped with two power supplies installed.

• Ensure that the devices to be installed are supported. For a list of supported optional devices for the server, go to: Lenovo ServerProven website

  CAUTION

  1. 240 V dc input (input range: 180-300 V dc) is ONLY supported in Chinese Mainland.

  2. Power supplies with 240 V dc are not hot-swappable. To remove the power cord, ensure you have turned off the server or disconnected the dc power sources at the breaker panel.

  3. In order for the ThinkSystem products to operate error free in both a DC or AC electrical environment, a TN-S earthing system which complies to 60364-1 IEC 2005 standard has to be present or installed.

  Note

  • Ensure that the two power supply units installed on the server have the same wattage.

  • When replacing the existing power supply unit with a new power supply unit of different wattage, attach the power information label that comes with this option onto the existing label near the power supply unit.

在直流输入状态下，若电源供应器插座不支持热插拔功能，请务必不要对设备电源线进行热插拔，此操作可能导致设备损坏及数据丢失。因错误执行热插拔导致的设备故障或损坏，不属于保修范围。

NEVER CONNECT AND DISCONNECT THE POWER SUPPLY CABLE AND EQUIPMENT WHILE YOUR EQUIPMENT IS POWERED ON WITH DC SUPPLY (hot-plugging). Otherwise the equipment and result in data loss may be damaged, the damages and losses result from incorrect operation of the equipment will not be covered by the manufacturers’ warranty.

Procedure

1. Remove a power-supply-bay filler, if any.
   Important

   To ensure proper cooling during normal server operation, both of the power supply bays must be occupied. This means that each bay must have a power supply unit installed; or one has a power supply unit installed and the other has a power-supply filler installed.
2. Note the orientation of the power supply unit; then, slide it into the chassis until it snaps into position.
