I. OUTLINE
I. 1. What is NetMan ?
This device is a network interface between the UPS and the LAN, is able to communicate in
severals way:
• TCP/IP UDP to be used in combination with our management software that is available for
all the common operating systems present on the market.
• HTTP to monitor the UPS status directly from a normal web browser without any added
software
• Telnet to configure the NetMan throw the network
• NetMan is able also to manage a modem. This is used to call the service center, that
immediately report the UPS failure.
I. 2. What is SNMP ?
With nowadays market environment using computer networks which become larger
and more complex, it is important to protect precious and confidential information and data.
Your computer systems connected to an uninterruptible power supply prevents from any data
loss in case of electricity outage. And what you need is a reliable equipment for monitoring and
control over each UPS within your computer system.
To monitor critical or operational states there is a standard network protocol for
network management - Simple Network Management Protocol (SNMP). This protocol is a
particle of IP protocols set even when there are solutions based on other network protocols
(IPX, etc.).
A PC or workstation supported by your UPS may perform the critical function that
cannot be cancelled by the provided network station monitoring. Or, your UPS may support
peripheral accessories and not the PC or workstation that has the ability, with suitable
software, to monitor the UPS directly via a serial interface network solution for monitoring
and control of the UPS.

Management Information Base ( MIB )
MIB (Management Information Base) is a virtual structure used for communication
between a NMS and SNMP Agent. MIB consists of OIDs (Object Identifiers) that label the
variables which can be controlled and monitored by a NMS (Network Management Station).

I. 3. What is Network Adapter?
The Network Adapter enables the network management of UPS units or other
equipment. Adapter is supplied with basic accessories that can be completed according to
individual customer's needs and requirements. In Figure 1 you see the Network Adapter
(NetMan101 version), in Figure 2 there is an example of connection between Network
Adapter NetMan 102 and UPS; this device is an expansion card for your UPS to insert directly
into UPS slot (for Ups models supporting that), but functionality is exactly the same of
NetMan101: in this manual everything explained about NetMan101 is the same for
NetMan102.

NETWORK
Fig. 3 Connecting Network Adapter NetMan 101 to an U S
Adapter connects to the twisted-pair Ethernet (10 base T) network via RJ-45
connector.
Adapter communicates with a NMS via the Ethernet network. Adapter includes SNMP
agent that implements Management Information Base (MIB) and, at the same time,
communicates with the UPS via a serial interface, and thus creates a data interconnection
between the systems.
Network Management Stations (NMS) can receive critical states of the UPS (traps)
and are able to monitor the important data about the UPS, for example input and output
voltages, battery status, etc. Moreover, the set of SNMP commands can remotely activate
various instructions for the UPS and control the supply of power from the UPS to the
connected load. For example it supports a remote restart of connected equipment.

Fig. 3 Connecting Network Adapter to the network.
Network adapter was designed after a careful consideration of needs of wide range of
network environments. As a result it offers network management with several supports :
* Universality and flexibility
* Network Interface Card (NIC) slot provides the Network Adapter, via a
manufacture-configured interface, to Ethernet.
User-configured parameters are stored in the Network Adapter´s nonvolatile memory.
Configuration can be updated via RS-232 port via a terminal.
Some proceeds in this Manual utilize specific parts of the Network Adapter. Before
you start working under these proceeds, make familiar with the Adapter's specific parts. In
Figure 4 you see the Adapter and its main parts.

I. 4 System requirements
Before you begin to install Network Adapter, make sure to have the following parts:
• items given in article I.3 Package content
• possibility to create network connection
• Network Management Station (NMS) based on SNMP, to verify the installation or the web
browser to test the HTTP communication or the UPS management software to test the
UDP communication.
• terminal (Terminal Emulation Station) with RS-232 and terminal emulation software for
SNMP Agent configuration. This terminal can be a PC or other computer capable of
activating the terminal emulation software with X-modem protocol. It must be capable of
connection to Network Adapter via RS-232 connection. Terminal emulation software can
be either Windows HyperTerminal or any similar software pack.
• equipment cooperating with Network Adapter, in this case an UPS.
• following values :
- IP address and network mask of Network Adapter for the given network
- IP address of a NMS for sending traps
- Community definitions for Network Adapter
- IP address of gateway/router
