DESCRIPTION
OVERVIEW
NetMan 204 is a device that allows UPS management through a LAN (Local Area Network); the
accessory supports all the main network protocols (SNMP v1 and v3, TCP/IP, HTTP and so on)
and is compatible with Ethernet 10/100Mbps IPv4/6 networks. The UPS can therefore be
integrated easily into medium and large-sized networks.
The device also records UPS values and events in the history log archive and can manage
optional environmental sensors (not supplied with the device, but provided separately)

NETWORK SERVICES
NetMan 204 implements a series of services based on the main network protocols. These services
can be activated or deactivated according to requirements (see paragraph “Configuration”). A brief
description for each of these is given below.
SSH
By means of a SSH client (available on all the main operating systems) a remote connection with
NetMan 204 can be established to change its configuration (see paragraph “Configuration via
SSH”).
Serial network
To emulate a point-to-point serial connection through the network (TCP/IP protocol) in order to use
special function service software.
Wake-on-LAN
NetMan 204 can send “Wake-on-LAN” command for remote computers boot.
HTTP
Using the HTTP (Hyper Text Transfer Protocol), is possible to configure the NetMan 204 and the
status of the UPS can be monitored by means of a web browser without having to install additional
software. All the most popular web browsers are supported.
SNMP
SNMP (Simple Network Management Protocol) is a communication protocol that allows a client
(manager) to make requests to a server (agent). NetMan 204 is an SNMP agent.
To exchange information, manager and agent use an addressing technique called MIB
(Management Information Base). There is a MIB file for each agent, defining which variables can
be requested and the respective access rights. The agent can also send messages (TRAP) without
a prior request from the manager, to inform the latter of particularly important events. SNMPv3 is
the evolution of SNMP and introduces new important features related to security. (See paragraph
“SNMPv3”).
UDP
UDP (User Datagram Protocol) is a low level network protocol that guarantees speed in the
exchange of data and low network congestion. It is the protocol used by the UPSMon software for
monitoring and control of the UPS.
The UDP connection uses the UDP 33000 port by default but can be configured on other ports
according to requirements.
- 9 -
Modbus TCP/IP
The UPS status can be monitored by means of the standard network protocol MODBUS TCP/IP.
Modbus TCP/IP is simply the Modbus RTU protocol with a TCP interface that runs on Ethernet.
BACnet/IP
The UPS status can be monitored by means of the standard network protocol BACnet/IP.
BACnet (Building Automation and Control networks) is a data communication protocol mainly used
in the building automation and HVAC industry (Heating Ventilation and Air-Conditioning).
FTP
FTP (File Transfer Protocol) is a network protocol used for file exchange. NetMan 204 uses this
protocol for:
1. download of files of the UPS values and events history log archive (Datalog and Eventlog);
2. download and upload of configuration files;
3. firmware upgrade.
In both cases a client FTP is required, configured with these parameters:
• Host: hostname or NetMan 204 IP address;
• User: see chapter “Users”;
• Password: current password.
The connection can also be established using a web browser (all the most popular web browsers
are supported), by inserting the hostname or IP address of the NetMan 204.
NetMan 204 can send a notification e-mail if one or more alarm conditions occur. The e-mails can
be sent to up to three recipients and they can be sent for seven different kinds of alarm.
SMTP (Simple Mail Transfer Protocol) is the protocol used to send the e-mails. They are sent to an
SMTP server on port 25. For more details, see paragraph “Configuration”
Reports
NetMan 204 can send periodic e-mails with an attachment containing the files of the UPS values
and events history log archive.
This service can be used to periodically save the history log archives.
The “Email” service must be enabled in order to send reports; the reports are sent to all the
addresses configured for this service (for more details see paragraph “Configuration”).
- 10 -
UPS VALUES AND EVENTS HISTORY LOG ARCHIVE
NetMan 204 records the UPS values (Datalog) and events (Eventlog) in a history log archive. The
data are saved to file in text format.
The format used to record the date and time is of the type: YY/MM/DD HH:MM:SS
Eventlog
The Eventlog service is always active and records all relevant UPS events in the ‘event.log’ file.
The file can be downloaded via FTP or sent by e-mail using the “Email report” service. The data
are saved in circular list mode, thus the most recent data are saved by overwriting the oldest data.
Datalog
The Datalog service records the main data of the UPS in the ‘data.log’ file. The file can be
downloaded via FTP or can be sent by e-mail using the “Email report” service. The following data
are monitored:
• Input voltage phase 1
• Input voltage phase 2
• Input voltage phase 3
• Input frequency
• Output voltage phase 1
• Output voltage phase 2
• Output voltage phase 3
• Load on phase 1
• Load on phase 2
• Load on phase 3
The interval of time between one recording and the next (Log frequency) can be configured by the
user (see paragraph “Miscellaneous Menu”). The data are saved in circular list mode, thus the
most recent data are saved by overwriting the oldest data. Data for up to 256 different points of
time can be recorded.

ENVIRONMENTAL SENSORS (OPTIONAL)
It is possibile to connect to NetMan 204 the environmental sensors for monitoring temperature,
humidity and digital input/output.
The information provided by these sensors can be showed with the UPS monitoring and control
software or with a web browser (the HTTP service must be active).
The values provided by the sensors may also be requested with SNMP according to the RFC 3433
standard (MIB files in the bundled CD).
Available sensors
• Temperature: detects the environmental temperature in °C.
• Humidity & Temperature: detects the relative humidity in % and the environmental
temperature in °C.
• Digital I/O & Temperature: detects the environmental temperature in °C and features a
digital input and a digital output.
It is possible to connect up to 3 environmental sensor to a NetMan 204 (for sensor
installation please see the sensors’ manual).
INSTALLATION
1. Remove the cover of the UPS expansion slot by removing the two retaining screws.
2. Insert NetMan 204 in the slot.
3. Secure Netman 204 in the slot using the two screws removed previously.
4. Connect the device to the network by means of connector RJ-45 (see “Specifications for the
