SAN512B-6 Installation, Service, and User Guide
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 Appendix B, "Product
specifications," on page 235.
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 Chapter 6, "Monitoring the
switch," on page 69.
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.
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.
