Remove a Power Conversion Station (PCS)

Use this information to remove a Power Conversion Station (PCS).

About this task

Attention

For safety reasons, when removing a tray or a PCS, it is highly recommended to use the Genie® Lift™ GL™-8 due to the server’s weight. Lenovo offers the lift with add on fixtures Genie Lift GL-8 Option Kit and GL-8 Kit for N1380 and SC Systems. If no lift tool is available on-site, customers must move the machine to an accessible, powered area before the trained technician arrives and handles reinstallation. Lenovo strongly advises configuring a complete solution for N1380 and SC-Systems with the lift tool and its add-on features via non-racked items.

Attention

Mandatory tool for tray removal and installation.

• Lift tool assembly

  • Genie GL-8 lift tool installed with the lift tool fixture. The foot-release brake should also be attached to the lift tool.

  • For assembling instructions, see Setting up the lift tool assembly

• For mandatory tools ordering information, see ThinkSystem server options.

The PCS is extremely heavy. When moving the PCS, always hold the PCS by its handles (1), and make sure to keep both latches in the closed position.

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.

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.

S040

CAUTION

Protective gloves should be worn for this procedure.

CAUTION

High touch current. Connect to earth before connecting to supply.

Attention

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

• Disconnect the power cord from the connector on the back of the power conversion station.

• If only one PCS is installed in the solution, you must turn off the solution before removing the power conversion station.

• In some configurations, the PCS are connected to a Y-splitter power cord. In such cases, the Y-splitter cord is connected to a rack power cord that is connected to the facility power outlet. It is NOT allowed to disconnect the Y-splitter power cord and the rack power cord.

Important

Before removing the PCS, it is strongly suggested to reduce the power loading of each node installed in the enclosure by turning the node into idle state or power off state.

When removing the PCS, the following SMM3 event messages may appear. These SMM3 event messages can be ignored before a replacement PCS is installed. For more information, see Messages.

Table 1. SMM3 messages after removing a PCS
