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 “Desktop” Cord Management system allows you to
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 “awakened” in stages to prevent the
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 Laser Cut ID Numbers to
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.
CAUTION:
Before moving cart from one room to the next, wrap the power cords on the winders located on the side of the cart.
CAUTION:
No TV/Monitor to be used on top of cart.
