About this task

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.

Attention

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

• Power off the server and disconnect all power cords for this task. See Power off the server.

• 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.

• If the server is in a rack, remove it from the rack.

• If foot stands are installed on the server, pivot them inwards and lay the server on its side for easier operation.

Note

• Depending on the specific type, the PCIe adapter might look different from the illustration in this topic.

• Use any documentation that comes with the PCIe adapter and follow those instructions in addition to the instructions in this topic.
