Use the information in this section to identify potentially unsafe conditions with your server. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury.
Important: Electrical grounding of the server is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
Make sure all power cords are disconnected from the system when reading the following step in
this manual: “ |
offTurnthe server and peripheral devices and disconnect the power cords and all |
external cables. |
” |
CAUTION:
This equipment must be installed by trained service personnel, as defined by the NEC and IEC 60950- 1, Second Edition, the standard for Safety of Information Technology Equipment. Lenovo assumes you are qualified in the servicing of equipment and trained in recognizing hazards in products with hazardous energy levels.
Use the following checklist to verify that there are no potentially unsafe conditions:
1.Make sure that the power is off and the power cord is disconnected.
2.Check the power cord.
•Make sure that the third-wire ground connector is in good condition. Use a meter to measure thirdwire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.
•Make sure that the power cord is the correct type.
To view the power cords that are available for the server: a. Go to:

b. In the Customize a Model pane:
1) Click Select Options/Parts for a Model |
. |
2)Enter the machine type and model for your server. c. Click the Power tab to see all line cords.
•Make sure that the insulation is not frayed or worn.
3.Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo alterations.
4.Check inside the server for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.
5.Check for worn, frayed, or pinched cables.
6.Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

After the server performs a short self-test (power status LED flashes quickly) when connected to input power, it enters a standby state (power status LED flashes once per second).
The server can be turned on (power LED on) in any of the following ways:
•You can press the power button.
•The server can restart automatically after a power interruption.
Note: If the boot screen lingers with the message of “System Security - The system has been tempered with,” it means the server cover is not properly installed. Remove and reinstall it (see “Server cover replacement” on page 115); then, restart the server.
For information about powering off the server, see “Power off the server” on page 8.
The server remains in a standby state when it is connected to a power source. To remove all power from the server (power-on LED off), you must disconnect all power cables.
To place the server in a standby state (power-on LED flashes once per second):
•Start an orderly shutdown using the operating system (if supported by your operating system).
•Press the power-on button to start an orderly shutdown (if supported by your operating system).
•Press and hold the power button for more than 4 seconds to force a shutdown.

Important:
•Before you move the jumpers, turn off the server. Then, disconnect all power cords and external cables. Do not open your server or attempt any repair before reading and understanding the following information:
–http://thinksystem.lenovofiles.com/help/topic/safety_documentation/pdf_files.html
–“Handling static-sensitive devices” on page 33
•Any system-board switch or jumper block that is not shown in the illustrations in this document are reserved.

Some of the components in the server come with internal cables meant for specific connectors.
Before connecting the cables, read the following guidelines carefully:
•Turn off the server before you connect or disconnect any internal cables.
•Refer to the documentation that comes with any external devices for additional cabling instructions.
•Make use of the identifiers printed on the cables to locate the proper connectors.
•Ensure that the cable is not pinched and does not cover any connectors or obstruct any components on the system board.
Note: Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from the system board. Failing to release them before removing the cables will damage the cable sockets on the system board, which are fragile. Any damage to the cable sockets might require replacing the system board.
