Checking Basic Power Problems

1If the power indicator on the system front panel or power supplies does not indicate that power is available to the system, ensure that the power cables are securely connected to the power supplies.

2If the system is connected to a PDU or UPS, turn the PDU or UPS off and then on.

3If the PDU or UPS is not receiving power, plug it into another electrical outlet. If it still is not receiving power, try another PDU or UPS.

4Reconnect the system to the electrical outlet and turn on the system.

If the system still is not working properly, see "Troubleshooting Power Supplies" on page 154.

Checking the Equipment

This section provides troubleshooting procedures for external devices attached to the system, such as the monitor, keyboard, or mouse. Before you perform any of the procedures, see "Troubleshooting External Connections" on page 144.

Troubleshooting External Connections

Loose or improperly connected cables are the most likely source of problems for the system, monitor, and other peripherals (such as a printer, keyboard, mouse, or other external device). Ensure that all external cables are securely
