DANGER
Make sure that the power source circuits are properly grounded, then use the power cord
supplied with the device to connect it to the power source.
c. If connecting to an AC power source, connect to a power source with voltage of 200–277 VAC,
50/60 Hz (recommended).
Note: Use of a high-voltage line (200–277 VAC) is highly recommended because of better
power-conversion efficiency. For a "fully-loaded" chassis with maximum supported blades and
optics, two power supplies connected to 200–277 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 Appendix B, “Product Specifications,” on
page 231.
DANGER
High Touch Current. Earth connection essential before connecting supply.
CAUTION:
Use a separate branch circuit for each power cord, which provides redundancy in case one of
the circuits fails.
10. If connecting to an DC power source, use the following steps. (If connecting to a AC power source,
go to step 9.)
a. Make sure that you observe applicable electrical caution and danger statements in “Safety
precautions” on page 7 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, refer to “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.
11. 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.
12. 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.
13. 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” on page 81.
14. Ground the chassis by attaching a ground wire from facilities 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.
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.
