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 235.
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 7.)
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” on page 45.
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.
