Http - Riello NetMan 202 plus User Manual

- ENGLISH -

HTTP

Using the HTTP (Hyper Text Transfer Protocol), is possible to configure the NetMan plus and the
status of the UPS can be monitored by means of a web browser without having to install additional
software (see paragraph "Monitoring with HTTP"). 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 plus is an SNMP agent.
To exchange information, manager and agent use an addressing technique called MIB
(Management Information Base). There is an 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.
Modbus
The UPS status can be monitored by means of the standard network protocol MODBUS TCP/IP.
This service is always active on the TCP port 502. The supported function are listed on section
"Modbus TCP/IP protocol", together with the accessible registers.
