X7-8 Director Hardware Installation Guide
CAUTION
Use a separate branch circuit for each power cord, which provides redundancy in case one of the circuits
fails.
8. If connecting to an DC power source, use the following steps. (If connecting to a AC power source, go to Step 7.)
a) Make sure that you observe applicable electrical caution and danger statements in Safety Precautions when
connecting this power supply.
b) Terminate the negative (-) and positive (+) unterminated wires on the HVAC/HVDC power cord to the DC power
source. Connect the ground wire to building ground.
For more information on the HVAC/HVDC power cord available for these power supplies, see Using HVAC/HVDC
Power Cords.
NOTE
Make sure that there is an adequate circuit breaker in the DC input circuit to the system based on input
wiring to the product and input voltage.
9. 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.
10. After power is applied, the power supply LED will light green.
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 on the device using the
diagDisablePost command.
NOTE
Do not connect the device to the network until the IP addresses are configured.
11. After POST is complete, verify that the power LEDs on blades and other FRUs are green.
For information about LED patterns, see the "Monitoring the Device" chapter.
12. Ground the chassis by attaching a ground wire from the facilities ground to an appropriate crimp connector and
attaching the connector to the 2AWG Panduit LCD2-14AF lug located under the fan assemblies near the bottom of the
chassis.
Using HVAC/HVDC Power Cords
HVAC/HVDC power supply power cords, available from Brocade, are shipped with an Anderson Saf-D-Grid 400 connector
on the power supply end and three unterminated 14 AWG UL 600V 90C wires with ring lugs on the power source end.
Power cord length is 6 m (19 ft. 8 in.). For connecting to a power source, attach either an AC power plug to these wires
that meets your facility and local code requirements, or connect these wires to appropriate DC power terminal blocks.
The following table defines the function of the 14 AWG wires in the power cable:
