Turn on Red Power Switch.
Green light glows as long as the Red Power Switch is
turned on. Power is now on inside the laptop cart.
Always-On Electrical Outlet stays on as long
as the Red Power Switch is on. (see below)
Green = Power On
Yellow = Power to the all the laptops
Blue = Turbo-Charge, 10 at a time
Amber = 2 Auxiliary Outlets ONLY
Setting the Combination Locks
Your new Intelligent Laptop Computer Cart comes equipped with two
re-settable Combination Padlocks. You can program them with the
same combination or different combinations – the choice is yours.
Each lock starts with 0-0-0-0. Follow the directions with the lock for
changing the combination. Remember to depress the shackle before
un-engaging it from the lock.
•Only One Electrical Plug to the wall outlet reduces nuisance tripping of circuit breakers.
• “Round Robin” sequencing e aluates the demand for power from each electrical strip of ten computers, concentrating on those batteries that ha e the most
demand for power.
• “Round Robin” also allows each electrical strip time to cool down. Cooler batteries last longer, and extended battery life sa es you money.
• A Divider Panel separates the computer/battery from the transformer, minimizing the transformer’s heat impact on the battery … cooler batteries last longer.
• The Brain recognizes as batteries become charged, and sends only enough power to keep the batteries well within their thermal limits, drawing only the
required power and sa ing you money.
• A single Mode Button lets you cycle through the arious settings, while the LED lights help keep track of what the power system is doing.
•Two Auxiliary Outlets on the top of the cart let you use a ideo projector or a printer with confidence, since the Brain will dedicate the power to those
accessories when you need to use them. Accidentally overloading the circuit is minimized!

Always-On Electrical Outlet
Under the Brain, accessible from the rear of the
cart, is one unique Electrical Outlet, rated for 1
Amp. This outlet is for a Wireless Access Point.
The Wireless Access Point’s power
cord can be routed through the cart at
the side cord-pass-thru-hole, opposite
the cart’s power cord. Remember, the
outlet is maximum 1 Amp, only.
Left alone, the Brain will automatically turn on the Yellow light, which
means that all power is being sent to charge the computer batteries.
Power Management System … “The Brain”

Power Strips A & B & C are controlled by the “Brain”, which shifts the
power from one strip to the other, and e en allows a “Turbo Charge”, where all

You know from personal experience the alue of keeping your
closet neat and organized. You know exactly where e erything is
when you open the door. So Bretford de eloped a “closet” for all
the cords and cables associated with Laptop Computers.
Your Intelligent Laptop Cart has its own “Cable Clutter
Closet” – a lockable compartment at the back of the cart
especially designed to keep all the cables away from the computers
and the hands that retrie e those computers from the cart.
The interior Divider Panel separates the cart so that 75% of
the cart is dedicated to the computers in the front and 25% is
dedicated to cables and power adapters in the back. Holes in the
Di ider Panel allow the computer connector cables to pass thru and
be easily connected to the computers for charging.
By separating the computer from its power adapter, you minimize the amount of
heat beside the computer battery, allowing it to charge at a lower temperature,
… allowing the battery to charge faster.
(see “How Does a Laptop Computer Manage Heat?” above)
Only the IT Administrator has access to the Cable Clutter Closet, since
it has its own programmable Combination Padlock.
Fold-back doors for easy access and full iew of the closet – you
immediately know if something is missing or out of place.
Special Cable Bins for the power adapters and their cables pro ide
nesting for cordsets.
Comes with appropriate stickers for color and number coding the
computers, the slots and the cable sets.

ELECTRICAL: A oid sparks. A oid arcing Always turn OFF the power to the cart before plugging IN or OUT!
ELECTRICAL: For Safety Purposes, make sure all electrical components do not exceed the the maximum load rating of 12 amps.
ELECTRICAL: Risk of electrical shock. Do not plug the power cord into another extension cord or relocatable power tap.
ELECTRICAL: The Power Bars inside the laptop cart are only for charging laptop computers. Any other use may cause an
o erload for the Power Management System, causing the “Brain” to shutdown, resulting in the LED lights flashing on and off.
To reset the Brain, turn off the main power switch, unplug the non-laptop computer, then turn the main switch back on.
CAUTION: Ventilation is critical for laptop computer carts to operate correctly, pro iding the appropriate airflow so that
heat-buildup is minimized during the battery-charging process, with the computers turned OFF. Be sure each laptop
computer is turned OFF before plugging into the cart.
CAUTION: Do Not block the entilation holes on the cart. Proper air flow is required for safe operation of equipment.
CAUTION: Cart with computers should be keep in a room with a maximum temperature not to exceed 77° F or 25° C.
CAUTION: Maximum weight of accessories on top of cabinet is 25 pounds. Do not block entilation holes when charging batteries.
CAUTION: A oid loading equipment in the cart in a une en fashion. Une en weight distribution could cause a hazardous condition.
How Does a Laptop Computer Manage Heat?
To manage the heat stress of the battery, computer engineers include
sophisticated battery management functions in the design of the computers.
They can be found in two places: the external charger & internal to the
notebook computer itself. The transformer con erts the alternating current
from the wall socket to a lower oltage direct current. Besides charging the
notebook’s battery these “bricks” as they’re sometimes called, can supply
enough electricity to operate the laptop and charge the battery
simultaneously.
Deep inside the computer a dedicated microcircuit continuously monitors
and manages the charging current, oltage and temperature of the battery.
If the temperature of the battery exceeds limits, the microcircuit will stop
charging the battery until the temperature drops to acceptable le els.
Keeping the battery cooler while charging allows the battery to charge faster.
