introduction
In critical situations, count on MGE UPS
SYSTEMS Pulsar EX20 and EX30
uninterruptible power supplies (UPS). Their
protection keeps your data intact and
accessible.
Pulsar EX20 and EX30 UPSs ensure top
quality power around the clock, and continue
operations during power failures. An
intelligent microprocessor detects any
operating anomalies of the UPS and triggers
an alarm if corrective action is necessary.
In addition to the high-technology aspect of
these UPSs, you can count on backup from
our staff, a team of specialists, around the
corner from you, throughout the world. It’s
no accident that MGE UPS SYSTEMS is the
world leader in UPS protection. The UPS
shall provide power factor correction to
prevent harmonic distorsions and current
created by non-linear critical loads from
polluting the incoming AC line.
UPS includes:
cbatteries,
cpower factor correction / battery charger,
cDC to DC converter,
cDC to AC Converter,
cbypass switch,
cinput/output filters.
The MGE Pulsar UPS is capable of
providing the following modes of operation:
cON LINE MODE which is the primary
mode of operation in which the critical load
is continuously supplied by the inverter and
protected from all forms of power line
disturbances:
ranging from atmospheric phenomena, to
nearby devices generating interference such
as elevators, photocopy machines and
machine tools, not to mention human errors,
like the accidental pulling out of power cords
or tripping of circuit breakers. The
consequences of these disturbances on
computer systems range from data losses to
hardware damage (power supplies, hard
disks).
Pulsar EX20 and EX30 are specially
designed to protect network servers and all
other interconnection devices that are
sensitive to electrical disturbances.
Pulsar EX20 and EX30 add fault-tolerance
to the utility supplying your sensitive
equipment.
Pulsar EX20 and EX30 are designed as
compact units and feature very quiet
operation. They can be installed under a
desk, and can also be installed in a rack
(see "options").
Pulsar EX20 and EX30 provide a stable
supply of clean power, long back-up time
during a utility outage (see table) and vast
information and control possibilities
according to the configuration selected.
Pulsar EX20 and EX30 On-Line technology
provides maximum protection and
availability of your workstations, server, and
network communication devices.
Pulsar EX20 and EX30 offer many functions
and characteristics designed to simplify
power management:
cautomatic battery test carried out
periodically. In the event of a fault, a LED
provides advance warning for battery
replacement;
cBYPASS MODE which is a default mode
in the event of an inverter failure or overload
in which the critical load is supplied AC
through EMI/RFI filter:
application of Pulsar EX20 and
EX30:
Network servers and interconnection
devices are very sensitive to electrical
disturbances of all types, including outages,
voltage sags, brownouts, spikes, etc. The
origins of the disturbances also vary,

cfront panel LEDs signal all types of faults
and alarms;
cBar graph continuously indicates the
battery charge level or the critical load
power level;
cPulsar EX20 and EX30 are environment
friendly: all components are recyclable and
an electronic power-saver device reduces
power consumption if the UPS is not active
for a period exceeding 5 minutes while on
battery back-up;
cEX Driver software provides rapid startup
of Pulsar EX20 and EX30 using the EX
Tuner configuration module. This module
adapts Pulsar EX20 and EX30 to user
preferences (battery test frequency, startup
and shutdown sequences, setting of battery
thresholds, etc.). Operation and monitoring
are ensured by the UPS Manager 3.1
module operating under Windows 3.1.
EX Driver connects to the RS 232 port on
the Pulsar EX20 and EX30 (see
"communication" section for further details);
cSolution-PacTM is a CD-ROM which
contains all the tools needed to supervise
your UPS.

with RFC 1628 specifications (IETF) and
was certified by the InterWorking Labs
during the Test Summit in June 1994;
cSNMP card: this card, inserted into your
unit, makes your UPS SNMP-compatible in
any environment;
cstatus information card: this option
provides you with 5 voltage-free contacts: on
battery, on by-pass, low battery, load on
UPS.
Contact your dealer for further information
on these options.

vi Pulsar EX : 51032278XT/AB MGE UPS SYSTEMS
software supplied with
Pulsar EX20 and EX30
To meet the different operating
environments of your UPS, Pulsar EX
includes 2 MGE UPS SYSTEMS software
programs:
cEX-Driver software for Windows (on 3.5"
diskettes);
cSolution-PacTM network software (on CD-
ROM).
EX-Driver for Windows
EX Driver for Windows provides
communication with the UPS from a simple
Windows workstation. EX-Driver is
compatible with Windows 3.1x and Windows
95, for communication with the UPS via a
serial connection for various needs:
cpersonalization of the UPS operating
mode: the EX-Tuner utility, can be used to
change certain UPS operating parameters if
the standard factory settings are not ideal for
the operating conditions.
It is possible to modify the output voltage,
battery-test frequency, startup and shutdown
sequences, operation of automatic by-pass,
etc.;
cUPS monitoring from a Windows
workstation and system safety:
EX-Driver, UPS Manager 3 software, can
display the UPS status, warn the user if a
problem arises, and provide automatic
shutdown.
The many possibilities available include:
vsupervision of operating parameters
through a graphic interface (display of
battery charge level, remaining battery time
and UPS load level). These values can be
recorded periodically in a log file,
vmessages to the user in case of power
outage or UPS problem and recording of
events in a log file,
vduring long-term power outages,
automatic shutdown of the system and of
the UPS, followed by automatic restart of the
UPS (system reboot) on return of utility
power,
vPowerShareTM functions.
Solution-PacTM for networks and
multi-station systems
Novell Netware, Windows NT, OS/2 Lan
Server, SCO Unix, etc.)
Protection by UPS is only complete and
effective if combined with powerful software
functions which warn users and the operator
of any power supply problem, automate
system shutdown, supervise and remotely
control the UPSs. MGE UPS SYSTEMS
created Solution-PacTM for this purpose.
Solution-PacTM combines all these functions
in a single CD-ROM, usable in local or
remote mode (SNMP), and covering the
main network environments.
Solution-PacTM is the ideal solution for
protecting networks and multistation
systems.
Solution-PacTM on a single CD-ROM
contains everything needed to safeguard
one or more systems and to supervise one
or more UPSs from a local or remote station.
Solution-PacTM includes SNMP UM-Agent,
UM-Client system shutdown software, and
UM-Console supervision software.
Solution-PacTM is a powerful and upgradable
software tool which provides all the
supervision, control and safety functions
associated with a UPS:
vgraphic display of the UPS,
vremote control of the UPS and output
receptacles,
vuser alarm of problems,
vrecording of events in log files,
vautomatic system shutdown and restart,
vlocal or remote supervision of UPSs and
ancillary devices,
vtransmission of UPS information and
alarms to any SNMP supervisor.

communication
cthe U-Talk communication port, at the rear
of the Pulsar, delivers information in the
form of an RS232 series link supported by
the communication protocol exclusive to
MGE UPS SYSTEMS.
The Solution-PacTM programs use the data
made available by this protocol.
option 1
cstatus information card: after the card is
installed in the rear of the Pulsar,
communication port transmits the status
information on a SUB-D 9-pin female
connector using the following pinouts:
1- ground,
2- remote power off,
4- normal operation,
5- common,
6- operation on utility power,
7- low battery warning,
8- load supplied by UPS,
9- operation on battery.
With the EX Driver software program you
can set up Pulsar EX to suit your user
conditions (EX Tuner), supervise your UPS
and safeguard your system (UPS Manager
3.1). To install EX Driver, connect the serial
cable supplied to COM1 to COM4 (set up by
EX Tuner) series port of your computer
equipped with Windows 3.1 on the one end,
and to the serial Pulsar EX connector on the
other end. Insert the disk and type A:\Install.
Follow the installation instructions on the
screen. You may then use 2 software
