The “Power Manager” has two LED indicator lights that let you know what it is happening

The left light is Amber and the right one is Red

Amber

Red

1. When the power button is switched to the “On” position, both

indicator lights will light up for approximately 2 seconds.

2. Both lights will then turn off while the “Power Manager” evaluates

the power required to charge the first set of devices.

3. The Amber light will come on and stay lit indicating that the “Power

Manager” is now in “Smart Charge” mode. This means that laptops

will be charged in groups, three minutes at a time.

4. Once the power needed to charge all of the devices in the cart

reaches a level that will not trip the circuit, the “Power Manager”

enters “All Charge” mode and both lights will be off. All devices are

now charging.

1. If both the Amber and Red lights start to blink, it means one set of devices is drawing too much current and the “Power

Manager” needs to be reset by turning it off and back on. If problem persists there may be a faulty device that needs to be

removed.

2. If the Amber light displays single blinks, it means the current required to power the auxiliary outlet is too high. Unplugging

whatever is in the auxiliary outlet should allow the “Power Manager” to resume charging the devices.

3. If the Amber light displays double blinks, the internal temperature of the cart is too high. Open the doors of the cart and/or move

the cart to a cooler room. The cart should cool down without having to turn off the “Power Manager”

How Does the Network Ready Cart Manage Heat?

When computers are charging, the source of heat is the adapter/transformer.

However, when they are receiving updates from your network, the computers must

be powered on meaning the source of the heat inside the cart is the computers’

ventilating themselves to keep their internal batteries cool. The air emitted from each

computer is very hot and with all 32 laptops ventilating at once, the internal

temperature of the cart rises dramatically while they are updating.

Computer manufacturers recommend a safe temperature range of 50°F to 95 °F for

operating laptops. To keep the internal temperature of the cart within these limits,

the MDM Network Ready Laptop Cart features ventilation on the side panels and is

equipped with two thermally-controlled fans that turn on when the temperature

inside the cart exceeds 77°F. Bretford has conducted extensive testing that

confirms the effectiveness of these features.

ELECTRICAL: Avoid sparks. Avoid 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 strips inside the laptop cart are only for charging laptop computers. Any other use may cause an

overload for the Power Management System, causing the Power Manager to shutdown. To reset the “Power Manager”, turn off the  

main power switch, unplug the non-laptop device, then turn the main switch back on.

CAUTION: Be sure each laptop computer is turned OFF before plugging into the cart..

CAUTION: Do Not block the ventilation holes or fans on the cart. Proper air flow is required for safe operation of equipment.

CAUTION: Cart with computers should be kept 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.

CAUTION: Avoid loading equipment in the cart in a uneven fashion. Uneven weight distribution could cause a hazardous condition.

Laser-Cut ID #’s in

front & back keep computers

and their cable sets in the right

place and make it easy to

identify if something is

missing.

The system allows you to “Desktop” Cord Management

organize the computer cord sets while seated at a table. No more

bending or kneeling behind the cart!! Simply remove the four

steel panels, secure the adapters with the Velcro straps, and re-

hang them in the rear of the cart.

Cable Management … Done at your Desk!

Power Manager

Uses the power from a

single wall outlet to charge

and update laptops safely

and efficiently.

When the Power Manager has moved through all of power modes described

in the blue box on the reverse side of this guide, the power required for all six

power strips will be below 10 amps and the network switch will be powered

on. Once on, the network switch will ALWAYS receive power until the Power

Manager is manually turned off.

If the combined draw of the power strips and network switch exceeds 10

amps, the cart will revert to “Smart Charge” mode. The network switch will

continue to get power but some computers will be running on battery power

every three minutes as the Power Manager redistributes the current.

Note that if the computers are updated remotely, they must be receiving AC

power to receive a “wake up” packet. Therefore, when using Wake-On LAN

we recommend the computers be to prevent the “awakened” in stages

Power Manager from reverting to “Smart Charge” mode. For example, the

“wake-up” packet would be sent to the computers in slots 1-8; once they are

on, the packet would be sent to the computers in slots 9-16, and so on until all

32 devices are powered on.

Since computers can receive updates while operating on battery power, the

update can now be sent to all 32 of them at once. If the computers are

powered on manually, updates can be sent to the entire cart simultaneously.

Dedicated Space

for your 19” rack-mounted

network switch.

For Best Results When Using the Networking Functionality,

We Recommend that All of the Computers in the Cart be

Fully Charged

Networking with the Power Manager

Mount your switch in the back of the cart

Remove the top panel in front of the cart

Plug your switch into the Power Manager

Getting Started

The cable management

channel includes a cut-out

designed to hold the Ethernet

cable and power cord in place.

Place the power cord on top of

the Ethernet cable and loop it into

the “notch” and over the hook at

the front.

Be sure to leave enough slack at both

ends of the power cord to be able to

plug one end into the power strip and

pass the other end through the divider

panel to the front of its assigned storage

slot. Use the to Laser Cut ID Numbers

quickly match computers with their cord

sets.

The MDM Network Ready Laptop Cart ships with 32 Ethernet

cables pre-wired in the rear of the cart. One end will be routed

to the dedicated space for your network switch and the other

end will be threaded through the divider panel into the cable

management channel in the front section of the cart.

Network updates sent to computers using the MDMLAP32NR are the responsibility of your IT Department. The information above explains

how the Power Manager will potentially affect these efforts and all recommendations are based on results of Bretford’s internal tests.
