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.
Connecting power cord to HVAC/HVDC power supplies
About this task
Use steps in this section to apply power to the dual-function high-voltage AC and DC (HVAC/HVDC)
power supply. This power supply converts high-voltage DC or AC input to appropriate DC power for the
device.
Make sure that you observe the electrical caution and danger statements in “Safety precautions” on page
7 when connecting this power supply.
Note: The equipment installation must meet NEC/CEC code requirements. Consult local authorities for
regulations.
Note: Power is supplied to the device as soon as the first power supply is connected to a power source.
CAUTION:
The maximum input voltage for connection to the HVAC/HVDC power supply should not exceed 305
VAC and 400 VDC.
CAUTION:
The maximum input voltage for connection to the HVAC power supply must not exceed 305VAC.
Procedure
1. If connecting to AC power, attach an AC power plug to the unterminated wires on the
HVAC/HVDC power cord that meets your facility and local code requirements. If connecting to DC
power, verify how you will attach these unterminated wires to your sites DC power terminal blocks.
For more information on the HVAC/HVDC power cord available for these power supplies, refer to
“Using HVAC/HVDC power cords” on page 51.
2. 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.
3.
Remove the protective cover if it is still installed over the top air vents on the port side of the
chassis.
