WARNING: Do not cross the wires — In the wiring block, blue
aligns with blue, green aligns with green, and black aligns with

3.
Use a flat-blade screwdriver to tighten the screws that secure the bare
wires into the wiring block.
4.
Insert the DC power connector cable end into the power socket of the
DC PSU and tighten the thumb screws. See items 1 and 2 in the figure.
WARNING: Never try to force the power connector into or out of
the DC PSU power socket.
NOTE: To remove the power connector from a DC PSU, unscrew the
thumb screws and pull the power connector from the DC PSU socket.
Installing a Fan Module
The four fan modules and the power supplies are hot-swappable if you install
a second (redundant) power supply.
NOTE: To run the system, the four fan slots must have operating fan
units. If you do not install a module in each slot, the system shuts down
in one minute.
NOTE: The system supports two airflow direction options. You can only
use a single direction in a chassis.
•
Normal is airflow from the I/O side to the power supply.
•
Reversed is airflow from the power supply to the I/O side.
There are environmental factors that could decrease the amount of time
required between fan replacements. Check these environmental factors
regularly. Any unusual environmental circumstance at the site that causes an
increase in temperature and/or particulate matter in the air might affect
performance (for example, new equipment installation).
1.
Remove the fan module from the shipping box.
2.
Use the grab handle to slide the module into the switch fan slot.
