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 device can be monitored by means of a web browser without having to install
additional software. All the most popular web browsers are supported; only most recent version of
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.
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 device.
The UDP connection uses the UDP 33000 port by default but can be configured on other ports
according to requirements.

- 10 -
Modbus TCP/IP
The device 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 device 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 device 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.
Syslog
Netman 204 can send events to a syslog server over UDP. This service allow to centralize the log
of the IT infrastructure on a single server, in order to have them consumed on the preferred way.
Email
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. The port is
configurable. For more details, see paragraph “Configuration”
Reports
NetMan 204 can send periodic e-mails with an attachment containing the files of the device 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”).

- 11 -
DEVICE VALUES AND EVENTS HISTORY LOG ARCHIVE
NetMan 204 records the device values (Datalog) and events (Eventlog) in a history log database.
Eventlog
The Eventlog service is always active and records all relevant device events in the ‘event.db’ file.
The file can be downloaded via FTP or can be viewed through the web page without credentials.
With the “Email report” service, is sent a .csv with the event of the last day or week according to
your setting. The data are saved in circular list mode; thus the most recent data are saved by
overwriting the oldest data.
Datalog (only for UPS devices)
The Datalog service records the main data of the UPS in the ‘datalog.db’ file.
This service writes a record each hour at 00 minutes, which summarizes the data of the past hour:
values are recorded at their minimum, maximum and medium. Records older than one year get
overwritten with new records.
The file can be downloaded via FTP or can be viewed through the web page (only the most
important values are shown on the web page) without credentials.
With the “Email report” service, the last records (last day or last 7 days according to your settings)
will be sent in a .csv format.

- 12 -
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 device monitoring and control
software or with a web browser.
The values provided by the sensors may also be requested with SNMP according to the RFC 3433
standard (MIB files on the download site).
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 device 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
cabling of the network cable”)

CONFIGURATION
OVERVIEW
NetMan 204 can be configured via USB, via SSH or via HTTP.
NetMan 204 comes provided as factory default with DHCP enabled and with the following
services active: SSH, HTTP, SNMP, UDP and FTP.
In order to change the configuration of NetMan 204, you have to log in as admin (default
password “admin”).
5
NetMan 204 needs approx. 2 minutes to become operational from when it is powered up
or after a reboot; before this time the device may not respond to commands that are sent
to it.
Configuration via HTTP/HTTPS
In order to change the configuration via http/https, you have to insert in your web browser the
hostname or IP address of the NetMan 204 and then log in as admin (default password: "admin").
The HTTPS service uses TLS (transport layer security) in order to provide cryptographic
security. However, the certificate used is self-signed and therefore the web browser may
prompt a security alert; in this case you can ignore the alert and proceed with the
configuration of NetMan 204.
Once login has been effected, you can browse through the menus to configure the NetMan 204.
In order to make a new configuration effective, it is necessary to save it. Some changes
are applied immediately, while other require a reboot of the NetMan 204 (as required with
a pop-up by your web browser).
