Ensure that you understand the danger notices for the uninterruptible power supply units.
Use the reference numbers in parentheses at the end of each notice, such as (C003) for example, to find the matching translated notice in IBM Systems Safety Notices.
DANGER
Do not open or service
any power supply assembly. (D005a)
DANGER
Uninterruptible power
supply units
contain specific hazardous materials. Observe the following precautions
if your product contains an uninterruptible
power supply:
- The uninterruptible power supply contains lethal voltages. All repairs and service must be performed only by an authorized service support representative. There are no user serviceable parts inside the uninterruptible power supply.
- The uninterruptible power supply contains its own energy source (batteries). The output receptacles might carry live voltage even when the uninterruptible power supply is not connected to an ac supply.
- Do not remove or unplug the input cord when the uninterruptible power supply is turned on. This removes the safety ground from the uninterruptible power supply and the equipment connected to the uninterruptible power supply.
- The uninterruptible
power supply is
heavy because of the electronics and batteries that are required.
To avoid injury, observe the following precautions:
- Do not attempt to lift the uninterruptible power supply by yourself. Ask another service representative for assistance.
- Remove the battery, electronics assembly, or both from the uninterruptible power supply before removing the uninterruptible power supply from the shipping carton or installing or removing the uninterruptible power supply in the rack.
DANGER
Observe the following precautions when working
on or around your IT rack system:
- Heavy equipment–personal injury or equipment damage might result if mishandled.
- Always lower the leveling pads on the rack cabinet.
- Always install stabilizer brackets on the rack cabinet.
- To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.
- Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices.
- Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.
- Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.
- An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
DANGER
- Do not install a unit in a rack where the internal rack ambient temperatures will exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.
- Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.
- Consideration should be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.
- (For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.
- (For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.
