Back-UPS
®
CS
Reliable power protection for office and home office computers.
All of the Back-UPS CS units provide plenty of runtime to
ride through momentary outages or shut down your system
in the event of an extended outage. Outlets are provided for
your computer, monitor and peripherals, as well as 1-line
phone/fax/modem/DSL surge protection. The compact
design conserves valuable floor space. All of the Back-UPS
CS units come with APC’s file-saving, automatic system-
shutdown software.
The Back-UPS CS 350 and 500 are the first UPSs to offer both
serial and USB connectivity. The Back-UPS CS 350 and 500
are equipped with visual alarms which tell you when the UPS
is running on battery and alert you of any problems concern-
ing the UPS or the wiring within the building.
The Back-UPS 650 offers up to 44 minutes of battery runtime
and is only available with serial connectivity. The Back-UPS
650 also provides user-adjustable voltage and alarm settings.
Internet connections
dramatically increase risk factor
While multiple peripherals and datalines to
and from your system are vital, plugging a
phone or DSL line into your computer doubles
your vulnerability to power problems. Add
any peripheral, (such as a printer), and the
risk is even greater.
Let's take lightning as an example. Lightning
strikes a nearby transformer. If the surge is
powerful enough, it travels instantaneously
through wiring, network, serial and phone
lines in a fashion analogous to a tidal wave.
The modem and motherboard are destroyed
first, then the chips and data are lost.
The utility responds to over-voltages by
disconnecting the grid, which creates
brownouts and blackouts. In the worst case
scenario, password protection on your
hard drive can be jumbled, or the file
allocation table may be upset, rendering
the hard disk useless.
