Install a hot-swap power supply unit

Follow instructions in this section to install a hot-swap power supply unit.

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.

S029

DANGER

danger

For -48V dc power supply, electrical current from power cords is hazardous.

To avoid a shock hazard:

• To connect or disconnect -48V dc power cords when you need to remove/install redundancy power supply unit(s).

To Connect:

To Disconnect:

Turn OFF subject dc power source(s) and equipment(s) that are attached to this product. Install the power supply unit(s) into the system housing. Attach dc power cord(s) to the product. Ensure correct polarity of -48 V dc connections: RTN is + and -Vin (typical -48 V) dc is -. Earth ground should be connected very well. Connect dc power cord(s) to subject power source(s). Turn ON all the power source(s).

Disconnect or turn off the subject dc power source(s) (at the breaker panel) before removing the power supply unit(s). Remove the subject dc cord(s) and make sure the wire terminal of power cord(s) is insulated. Unplug the subject power supply unit(s) from the system housing.

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.

About this task

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.

• Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

Procedure

1. Make preparation for this task.
   1. If the configuration is with only one power supply unit, install the power supply unit in PSU bay 1 (the right bay).
   2. If the configuration is with two power supply units, make sure the power supply units are with the same brand, power rating, wattage and efficiency level.
   3. If a power supply filler is installed in the bay, pull the filler out of the bay.
      Note

      During normal operation, each power supply bay must contain either a power supply unit or a power supply filler for proper cooling.
2. Make sure the label on the power supply is facing up; then, grasp the handle and slide it into the power supply bay until it clicks into place.

3. Connect the power supply unit to a properly grounded electrical socket with a power cord.
4. Make sure that the AC power LED on the power supply unit is lit, indicating that the power supply unit is operating correctly.
