Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard:
If IBM supplied a power cord(s), connect power to this unit only with the IBM provided power cord. Do not use the IBM provided power cord for
any other product.
Do not open or service any power supply assembly.
Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this product during an electrical storm.
The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords.
For AC power, disconnect all power cords from their AC power source.
For racks with a DC power distribution panel (PDP), disconnect the customer’s DC powersource to the PDP.
When connecting power to the product ensure all power cables are properly connected.
For racks with AC power, connect all power cords to a properly wired and grounded electrical outlet. Ensure that the outlet supplies
proper voltage and phase rotation according to the system rating plate.
For racks with a DC power distribution panel (PDP), connect the customer’s DC power source to the PDP. Ensure that the proper polarity
is used when attaching the DC power and DC power return wiring.
Connect any equipment that will be attached to this product to properly wired outlets.
When possible, use one hand only to connect or disconnect signal cables.
Never turn on any equipment when there is evidence of fire, water, or structural damage.
Do not attempt to switch on power to the machine until all possible unsafe conditions are corrected.
Assume that an electrical safety hazard is present. Perform all continuity, grounding, and power checks specified during the subsystem
installation procedures to ensure that the machine meets safety requirements.
Do not continue with the inspection if any unsafe conditions are present.
Before you open the device covers, unless instructed otherwise in the installation and configuration procedures: Disconnect the attached AC
power cords, turn off the applicable circuit breakers located in the rack power distribution panel (PDP), and disconnect any telecommunications
systems, networks, and modems.
Connect and disconnect cables as described in the following procedures when installing, moving, or opening covers on this product or attached
devices.
To disconnect:
1. Turn off everything (unless instructed otherwise).
2. For AC power, remove the power cords from the outlets.
3. For racks with a DC power distribution panel (PDP), turn off the circuit breakers located in the PDP and remove the power from the Customer's
DC power source.
4. Remove the signal cables from the connectors.
5. Remove all cables from the devices.
To connect:
1. Turn off everything (unless instructed otherwise).
2. Attach all cables to the devices.
3. Attach the signal cables to the connectors.
4. For AC power, attach the power cords to the outlets.
5. For racks with a DC power distribution panel (PDP), restore the power from the Customer'sDC power source and turn on the circuit breakers
located in the PDP.
6. Turn on the devices.
Sharp edges, corners and joints may be present in and around the system. Use care when handling equipment to avoid cuts, scrapes and
pinching. (D005)
Heavy equipment - personal injury or equipment damage might result if mishandled. (D006)
Uninterruptible power supply (UPS) units contain specific hazardous materials. Observe the following precautions if your product contains a UPS:
The UPS 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 UPS.
The UPS contains its own energy source (batteries). The output receptacles might carry live voltage even when the UPS is not connected to an
AC supply.
Do not remove or unplug the input cord when the UPS is turned on. This removes the safety ground from the UPS and the equipment connected
to the UPS.
The UPS is heavy because of the electronics and batteries that are required. To avoid injury,observe the following precautions:
Do not attempt to lift the UPS by yourself. Ask another service representative for assistance.
Remove the battery, electronics assembly, or both from the UPS before removing the UPS from the shipping carton or installing or
removing the UPS in the rack.
(D007)
Professional movers are to be used for all relocation activities. Serious injury or death might occur if systems are handled and moved incorrectly.
(D008)
Ensure that your DC mains supply is earthed at the point of generation per IEC 60950-1and ITU-T Recommendation K.27. (D009)
Serious injury or death can occur if loaded lift tool falls over or if a heavy load falls off the lift tool. Always completely lower the lift tool load plate and
properly secure the load on the lift tool before moving or using the lift tool to lift or move an object. (D010)
DANGER
Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages,
disconnect all power cords and power cables. (L003)
Caution notices
A caution notice calls attention to a situation that is potentially hazardous to people because of some existing condition, or to a potentially dangerous situation that might
develop because of some unsafe practice.
