Install a hot-swap power supply unit

Use this information to install a hot-swap power supply unit.

About this task

The following describes the information that you must consider when installing a power supply unit:

• If the power supply unit to be removed is the only one installed, the power supply unit is not hot-swappable. Before removing it, you must turn off the server first. To support redundancy mode or hot-swap, install an additional hot-swap power supply unit.

• If you are replacing the existing power supply with a new power supply:

  • Use Lenovo Capacity Planner to calculate the required power capacity for what is configured for your server. More information about Lenovo Capacity Planner is available at: Lenovo Capacity Planner website.

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

  • Attach the power information label that comes with this option on the existing label near the power supply.

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.

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.

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.

Safety information for DC power supplies

CAUTION

240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland ONLY. Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.

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 you may damage the equipment and result in data loss, the damages and losses result from incorrect operation of the equipment will not be covered by the manufacturers’ warranty.

CAUTION

The power-control button on the device does not turn off the electrical current supplied to the device. The device also might have more than one connection to dc power. To remove all electrical current from the device, ensure that all connections to dc power are disconnected at the dc power input terminals.

Attention

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

• Keep static-sensitive parts in their static-protective packages until installation to prevent exposure to static electricity. Handle the parts with an electrostatic-discharge wrist strap or other grounding systems. Place the parts on a static-protective surface.

Procedure

1. If there is a power-supply-unit filler installed, remove it.
   Figure 2. Hot-swap power-supply-unit filler removal
   

   

   
   
   1. Pinch the latches to unlock the power-supply-unit filler.
   2. Pull out the filler.
2. Slide the new hot-swap power supply unit into the bay until it snaps into position.
   Important

   • Depends on the model, the color of release tab might be different.

   • If the power supply unit is to be replaced by a new one, make sure that the new one has identical color of the release tab, wattage and efficiency with the old one.

3. Connect the power supply unit to a properly grounded electrical outlet.

   • For 240 V DC power supply units:

     1. Turn off the server.

     2. Connect one end of the power cord to the power connector on the power supply unit.

     3. Connect the other end of the power cord to a properly grounded electrical outlet.

   • For AC power supply units:

     1. Connect one end of the power cord to the power connector on the power supply unit.

     2. Connect the other end of the power cord to a properly grounded electrical outlet.

4. Make sure the power supply unit handle is perpendicular to the power supply unit; then, tie the power cord to the handle with the pre-attached strap as shown below.
