Warning
The Industrial Ethernet OSM/ESM is designed for operation with safety extra-low
voltage (SELV). This means that only safety extra-low voltages (SELV) complying
with IEC 950/EN 60950/VDE 0805 may be connected to the power supply
terminals or the signaling contact.
For more detailed information on the OSM/ESM, refer to the “Industrial Ethernet
OSM/ESM” operating instructions in the appendix of this manual.
6.2.9 Network Management of the OSM/ESM
Functions
Network management provides the following functions:
Password protected login for administrators (write and read rights) and users (read
rights only)
S Reading out version and status information
S Setting the message and standby mask and address information
S Fixed parameter settings for ports and filter tables
S Output of statistical information
S Diagnostics of data traffic via a selectable mirror port
S Downloading new firmware versions via the network
If problems occur in the network, the OSM/ESM can send error messages (traps)
automatically to a network management system or E-mails to a network
administrator.
Remote Monitoring
Remote monitoring (RMON) provides the following functions:
The OSM/ESM is capable of visualizing statistical information according to the
RMON Standards 1 to 3. These include, for example, error statistics maintained for
each port separately.
