Connect Equipment Power Cords to PDUs

After installing equipment into the rack, connect the power cords to the PDUs.

Note -  Refer to the Sun Rack II User's Guide and your equipment documentation for instructions on installing equipment into the rack.
  • Connect the power cords using these guidelines.

    As you connect power cords, label each power cord and note which outlet it is connected to, in case you need to replace or move equipment in the rack.


    Caution  -  When connecting equipment to the PDU, ensure that you install the most symmetrical load to all of the phases as possible.


    Caution  -  Circuit Overloading – When connecting equipment to the PDU, consider the damaging effect that overloading the circuits might have on overcurrent protection and supply wiring. Always review the equipment nameplate ratings when considering circuit overloading issues.

    • When routing jumper cords, avoid cluttering the center of the rack by first routing the jumper cords away from the PDU. Then route the jumper cords through your equipment cable management device to your equipment.

    • Do not connect all of the equipment to the same PDU group of sockets.

    • For equipment with dual redundant power supplies (two power supplies), connect each power supply to different PDUs.
