This section contains information for trained service technicians.
Inspecting for unsafe conditions
Use the information in this section to help you identify potential unsafe conditions in
an IBM®product that you are working on. Each Lenovo product, as it was designed
and manufactured, has required safety items to protect users and service
technicians from injury. The information in this section addresses only those items.
Use good judgment to identify potential unsafe conditions that might be caused by
non-Lenovo alterations or attachment of non-Lenovo features or options that are not
addressed in this section. If you identify an unsafe condition, you must determine
how serious the hazard is and whether you must correct the problem before you
work on the product.
Consider the following conditions and the safety hazards that they present:
v Electrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
v Explosive hazards, such as a damaged CRT face or a bulging or leaking
capacitor.
v Mechanical hazards, such as loose or missing hardware.
To inspect the product for potential unsafe conditions, complete the following steps:
1. Make sure that the power is off and the power cord is disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and
observe any sharp edges.
3. Check the power cord:
v Make sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between
the external ground pin and the frame ground.
v Make sure that the power cord is the correct type, as specified in “Power
cords” on page 51.
v Make sure that the insulation is not frayed or worn.
4. Remove the cover.
5. Check for any obvious non-Lenovo alterations. Use good judgment as to the
safety of any non-Lenovo alterations.
6. 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.
7. Check for worn, frayed, or pinched cables.
8. Make sure that the power supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Observe the following guidelines when you service electrical equipment:
v Check the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
v Use only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical currents.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
v Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
v Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
v Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
v Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you are working with powered-on electrical equipment, use only one
hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
v Use extreme care when you measure high voltages.
v To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
v If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.

Note: When 4 GB or more of memory (physical or logical) is installed, some
memory is reserved for various system resources and is unavailable to the
operating system. The amount of memory that is reserved for system resources
depends on the operating system, the configuration of the server, and the
configured PCI optional devices.
Turning off the server
When you turn off the server and leave it connected to ac power, the server can
respond to requests from the service processor, such as a remote request to turn
on the server. While the server remains connected to ac power, one or more fans
might continue to run. To remove all power from the server, you must disconnect it
from the power source.
Some operating systems require an orderly shutdown before you turn off the server.
