NOTE: On Managed Charging Carts, an LED indicator displays when power is distributed to the external
outlets. If there is available current while the Aux outlets are in use, it will be directed to charging the
notebooks. Once external equipment is unplugged or turned off, full charging activity resumes. First-level
power priority is given to the auxiliary, switch and WAP outlets. Notebook outlets will receive current if there
is remaining power available.
Timer Controller Sorting/prioritizing of power allocation happens when the cart is plugged in and when a new factor (such as
plugging in an additional notebook, use of the external auxiliary outlets, etc) is introduced or at regular
intervals if no new event occurs.
Fast Response Inrush
Current Limit
Phases the power of the notebook outlets up over four (20 unit carts) or six banks (30 unit carts), preventing
breaker from tripping on start up of charging. All notebook outlets are powered up in groups of five after the
turn-on delay and will remain powered up until an over-temperature fault, circuit breaker trip, AC cord
removal, charging or managing the next bank, auxiliary outlet is used or site power is removed.
LED Status Indicators None Eight LED lights with
corresponding icons are
located on the top work
surface for easy read out.
Indicators show the following
power information:
White Solid – HP logo
Blue Solid – Power to
the cart
White Solid – Power to
the external outlets
Blue Slow Flashing –
Bank (1-4) is charging
Blue Fast Flashing –
Cart is sensing the
current draw
Amber Flashing – Max
recommended
temperature is
exceeded and power is
removed from the
notebooks (overtemp)
None Ten LED lights with
corresponding icons
are located on the top
work surface for easy
read out. Indicators
show the following
power information:
White Solid – HP
logo
Blue Solid –
Power to the
cart
White Solid –
Power to the
external outlets
Blue Slow
Flashing – Bank
(1-6) is charging
Blue Fast
Flashing – Cart
is sensing the
current draw
Amber Flashing
– Max
recommended
temperature is
exceeded and
power is
removed from
the notebooks
(overtemp)
NOTE: At cart start up, the system initiates a current sensing action. During
this time, the bank being sensed will flash fast until the sensing activity is
complete. Interval length is optimized at 30 seconds per bank for current
sensing and 10 minutes per group for charging.
