Connecting power cord to AC power supplies

About this task

Complete the following steps to connect the power cord from the facility AC power source to the device 's AC power supply. Before connecting to power, be sure to observe all "Power Precautions" in Safety precautions. In addition, refer to the power supply specifications and requirements in Product Specifications.

Procedure

  1. Remove the protective cover if it is still installed over the top air vents on the port side of the chassis. Refer to Removing the protective cover for instructions.
    CAUTION:
    Remove the protective cover on the port side of the chassis before applying power. This cover is attached over the air vents. If not removed, the chassis can overheat and eventually shut down.
  2. Install all power supplies provided for your device if not already installed. Refer to Installing a power supply for procedures.
  3. When installing device in a rack, route power cables from power distribution units (PDUs) so they do not cover air vents in chassis.
  4. Connect the provided AC power cords to a power source with voltage of 200–240 VAC, 50/60 Hz or optionally to a power source with voltage of 100–120 VAC, 50/60 Hz.
    DANGER
    High Touch Current. Earth connection essential before connecting supply.
    Note: Use of the high-voltage line (200–240 VAC) is highly recommended because of better power-conversion efficiency. With 120 VAC primary input, the power distribution unit (PDU) supplies roughly half the available wattage, which can limit blade and port configurations. For a "fully-loaded" chassis with maximum supported blades and optics, two power supplies connected to 200–240 VAC are required for full N+N redundancy. For details on power supplies required for operation and high availability, refer to "Power supply requirements" and "Power consumption" tables in the Product Specifications.
  5. Route the cords so they will be out of the way when connected to the power source. Ensure that the power cords have a minimum service loop of 15.2 cm (6 in.) available and are routed to avoid stress.
  6. Plug the power cords into power supplies. The power supply LED will light green when power is applied. Note that after one power supply is plugged into AC power, LEDs on the remaining installed power supplies will flash green until they also have power applied.

    The director performs a power-on self-test (POST) each time it is powered on. POST takes approximately 10 minutes, during which time status LEDs on installed blades and other FRUs may display amber. Power LEDs on all FRUs display green when power-on self-test (POST) is complete and all FRUs are functional. You can bypass POST by using the fastBoot command. You can also disable POST for successive reboots using the diagDisablePost command.

    Note:

    Do not connect the device to the network until the IP addresses are configured.

  7. After POST is complete, verify that the power LEDs on blades and other FRUs are green.

    For information about LED patterns, refer to Monitoring the Device.

  8. Ground the chassis by attaching a ground wire from building ground to an appropriate crimp connector and attaching the connector to the 2AWG Panduit LCD2-14AF lug located to the left of the bottom fan assembly near the bottom of the chassis.
