If IBM supplied the 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.
o
For AC power, disconnect all power cords from their AC power source.
o
For racks with a DC power distribution panel (PDP), disconnect the
customer’s DC power source to the PDP.
•
When connecting power to the product ensure all power cables are properly
connected.
o
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.
o
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.
