• 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 power
source 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.
