DANGER: When working on or around the system, observe the following precautions:
Electrical voltage and current from power, telephone, and communication cables are hazardous. To
avoid a shock hazard:

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.
