To make the most of your MGE UPS and select the best solution for your configuration,
please consider the following points :
Which
Devices Require Battery Back-up and Which Don't ?
 |
 |
|
The CPU is the heart of
your system. You will of course want it to be fully protected against
power outages that can corrupt data or surges that can damage hardware. |
|
 |
|
Other devices with volatile
memory like external storage systems require battery back-up: you
can lose the data stored in memory in case of a power outage if you
don't protect them. |
|
 |
|
The monitor, even though
it doesn't have any memory, needs battery back-up: you don't want
to see what's going on and carry on working on your application in
case of an outage, don't you? |
|
 |
|
On the flip side, peripherals
like printers or scanners don't require battery back-up. Spikes and
other power disturbances can still damage their power supply, so you
will want to connect them on one of the surge-protected outlets of
Ellipse. |
What About Power Consumption?
 |
|
Flat panels add another
advantage to their small footprint: their power consumption is actually
very low: the 23" Cinema Display of Apple draws 1/3 of the
power of its 21" CRT equivalent! This is why you can use a smaller
UPS to get the same battery runtime. |
|
 |
|
Laser printers include
motors that require a lot of power (typically 300 watts at least).
Don't try to battery back them! The surge-only outlets of Ellipse
are perfect for these power hungry peripherals. |
