 AVU: Includes a 1U high integral chamber for inlet airflow and a 1U high fan
tray with an internal alarm module. The AVU comprises 10 brush-less fans,
where 9 fans are sufficient for cooling a fully loaded chassis.
 Power Feeder: The PIU can support a maximum current of 58 A (@-40.5 VDC).
In certain installations with a relatively high number of ODUs this current
may not be sufficient to power the shelf and all the ODUs. In such
installations the ODU Power Feeder is used as an additional power source
providing power (-48V DC) to ODUs. It transfers transparently all signals
between the AU and the ODU, while injecting DC power received from an
external source. Each ODU Power Feeder unit can serve up to four ODUs.
