System Access Warnings
CAUTION
The power button, indicated by the stand-by power marking, DOES NOT completely turn off the system AC or DC power, 5V standby
power is active whenever the system is plugged in. To remove power from system, you must unplug the AC or DC power cord from the wall outlet. Your
system may use more than one AC or DC power cord. Make sure the AC or DC power cord(s) is/are unplugged before you open the chassis, or add or remove
any non hot-plug components.
• Do not attempt to modify or use an AC or DC power cord if it is not the exact type required by the local electrical code. A separate AC or DC cord
is required for each system power supply.
• The AC and DC power supplies are not designed to function in parallel. Do not operate the AC and DC power supplies at the same time. The
power cords must meet the following criteria:
• The power cord must have an electrical rating that is greater than that of the electrical current rating marked on the product.
• The power cord must have safety ground pin or contact that is suitable for the electrical outlet.
• The power supply cords are the main disconnect device to AC or DC power. The socket outlets must be near the equipment and readily accessible
for disconnection.
• The power supply cords must be plugged into socket-outlets that are provided with a suitable earth ground.
• This equipment should be connected directly to the DC supply system grounding electrode conductor or to a bonding jumper from a grounding
terminal bar or bus to which the DC supply system grounding electrode conductor is connected.
• This equipment should be located in the same immediate area (such as adjacent cabinets) as any other equipment that has a connection be-
tween the grounded conductor of the same DC supply circuit and the grounding conductor, and also the point of grounding of the DC system.
The DC system should be grounded elsewhere.
• The DC supply source is to be located within the same premises as the equipment.
• Switching or disconnecting devices should not be in the grounded circuit conductor between the DC source and the point of connection of the
grounding electrode conductor.
The power supply in this product contains no user-serviceable parts. Do not open the power supply. Hazardous voltage, current and energy levels are pres-
ent inside the power supply. Return to manufacturer for servicing.
When replacing a hot-plug power supply, unplug the power cord to the power supply being replaced before removing it from the server.
To avoid risk of electric shock, turn off the equipment and disconnect the power cord attached to the server before opening it.
• Turn off all peripheral devices connected to this product.
• Turn off the system by pressing the power button to off.
• Disconnect the AC or DC power by unplugging all AC or DC power cords from the system or wall outlet.
• Disconnect all cables that are connected to the system.
• Retain all screws or other fasteners when removing access cover(s). Upon completion of accessing inside the product, refasten access cover with
original screws or fasteners.
CAUTION
If the server has been running, any installed processor(s) and heat sink(s) may be hot. Unless you are adding or removing a hot-plug
component, allow the system to cool before opening the covers to avoid the possibility of coming into contact with hot component(s). During a hot-plug
installation, be careful when removing or installing the hot-plug component(s) since some surfaces will be hot.
CAUTION
To avoid injury, do not contact moving fan blades. If your system is supplied with a guard over the fan, do not operate the system
without the fan guard in place.
