ONT Fan Tray
- On the far left, a small field replaceable fan unit cools the ONT
and preserves the life of ONT components. The fans are redundant and each
pair of fans has its own fail LED to indicate when failure has occurred. When the
fans are operating normally, the fan LEDs will both be green. There are two
thumbscrews which can be used to remove the fan unit and replace it in the
event of a failure. The fan unit has 4 fans in two groups to provide full fan
redundancy in the event of a fan failure.
·
Power Supply A/B
- Two redundant load sharing, field replaceable power
supplies are supported for the unit. You can maximize redundancy and
survivability by equipping both units and supplying AC power from two different
circuits on different circuit breakers. Both 715W and 1100W power supplies are
supported allowing support of different PoE power loads. The Power Supplies
support two LEDs:
o
Input OK
: If green, the AC input to the supply is good.
o
Output OK
: If green the DC output of the supply is good.

ONT Ground Lug
- A safety ground lug is provided to provide protection from
shock hazards.
